G0602 Lathe Accessory Upgrade – QCTP Tool Holder Storage Brackets!

Hi guys! I’ve been without internet due to a winter storm for more than a week. It’s good to be back!

Luckily I only lost power for 1 day following the storm. So I had a lot of time to play around with my newly constructed 3D printer. One of the first parts I made was a Quick Change Tool Post (QCTP) Tool Holder that would attach to the back of my Grizzly G0602 lathe’s backsplash. Here you can see 5 tool holder storage brackets clipped in place, with my trusty Diamond Tool Holder hanging on the first bracket.

I have an AXA (#100) piston-style QCTP and I needed a good way to store my tool holders. My tool holders were too tall to fit into all but the biggest drawer on my Kennedy tool chest, and I had other stuff occupying that space. So my tool holders always seemed to sit on the benchtop or on a clean part of my chip tray near my tailstock. Not ideal. I’ve knocked them off more than once – and they ALWAYS land cutting-edge down.

Then Norman sent me some cast aluminum tool holders that were an excellent yet simple solution to the problem. But they needed to be mounted to the wall to be used effectively. I didn’t have a wall nearby to bolt them to (I have metal shelving along every square foot of my shop walls) so I bolted them to a piece of 2×4 and clamped that near my lathe. That worked, but it wasn’t an ideal solution either.

So instead I took cues from Normans design and created an ABS plastic version that would clip to my G0602 backsplash. I’m very pleased with the results! Here’s a closeup:

The parts aren’t perfectly smooth like what you’d expect from an injection molded part. But then again, they don’t need to be smooth to perform their function. My 3D printer lays down layers of plastic in very thin (.010 or less) layers with an accuracy/resolution of .003 to .005 – just fine for a part like this. Each part takes a little over an hour to print, so they aren’t as quick to manufacture as an injection molded part either. But the setup cost for an injection mold for a part like this would be in the thousands just to have the mold made. I think that’s probably the reason nobody has bothered to manufacture a part like this before – they’d have a hard time making their money back on the initial mold investment if they sold the parts for $10 a piece. But having the ability to print a part like this eliminates the financial barriers associated with bringing it to market.

I’m going to list a few of these on eBay at $8 each. If ProjectsInMetal members/visitors would like to buy some I’ll sell them for $7 and cut eBay and their fees out of the equation. They are very light and thus inexpensive to ship. About $4 for the set of 5 that I sent to Norman (from Seattle to Texas via First Class Mail). Shipping outside the USA will be a bit more, but I won’t overcharge.

If the parts prove popular and a lot of people buy them I may look a little harder into an injection mold. But for now I’m extremely happy with the printed version. They are very strong (you’d have to try hard to break them) and fit my tool holders very well. As for the backsplash, the G0602 has a lip that is folded forward .06, and down .05. If you have a different backsplash with similar dimensions the brackets would probably fit with little to no modification. But if necessary they could be easily filed to fit a slightly larger backsplash lip. They won’t, however, fit a backsplash folded the opposite direction. But I could easily re-design the clip if you’ve got a lathe with different dimensions. Just let me know.

If you’d like to purchase, please use the PayPal button below. If you have trouble using the PayPal button, please send me a private message via the forum. Right now the only color I have is Black, and I have 10 in stock (but I can make more). Thanks!

  1. Tyler, are you going to offer other (larger) sizes?

     Woody

  2. I can modify both the dovetail size (to fit BXA or larger) as well as the clip size (to fit the dimensions of your backsplash). Were you looking to put this on a different lathe with a different backsplash or on a G0602 with a larger QCTP?

    If you're using a BXA I'll have to buy a cheap tool holder for testing, so it will take a few weeks to put a set together for you (I'll have to wait for the tool holder to get here).

    I'd do it strictly off of dimensions, but plastic shrinks in funny ways, so there's a fair amount of tweaking involved before you get a nice fit. I guess if I were a plastics engineer I could calculate shrinkage … but I'll stick with the easy way.

    I guess if I knew the exact dimensions of the BXA dovetail I could just create a plastic mockup of the dovetail and use that. I'll poke around online and see if I can find a chart that will tell me the sizes of the different dovetails.

    If your talking about a lathe with a larger backsplash lip I can do that as well, but my lathe has a +/- .02 variance along it's length. So it's impossible to get a perfect fit all along the backsplash. I guess they weren't too worried about the tolerances when they made that bend. But since it's plastic it's very easy to file it a bit if it's too snug, or add a strip or two of masking tape to the inside of the lip (where you wouldn't see it) to make it tighter if it's too lose. So as long as you're willing to fiddle a bit with the fit of the backsplash, I can modify that dimension as well.

    How many clips were you interested in?

  3. Here I hope this satisfies .

  4. Tyler, Thank you for the holders I received them in the mail today. I must say I'm impressed with them they look and work nice, fit on the splash guard really well. I'd sure like to see these or something being made by your printer.

    Here's some photos of them now I have 10 holders and 5 tools so I can buy more tools for the extra holders.

     

    Here's 3 holders doing their thing!

    2 of the holders, they snap right on the splash guard

    another view

    the holder, this is the side that clips into the guard. They can't damage the tool holder being made of plastic and they should not rattle or make any noise on the guard, at least I don't think they will.Laugh

  5. @Alexander – thanks Alex! That should make it easy!

    @norman – I'm glad you're happy with them! Thanks for posting pictures. My backsplash is +/- ten thou. So some spots are more snug than others with the clips. I tried to design the clip so that it fell in the middle of the tolerance. Were there any clips that were too loose or too tight on any spots along the backsplash? If they are too tight you could file them some. If they are too loose you could add a layer of masking tape as a shim (to the part, not the backsplash). 

    The last thing I want is the clips to fall off in use like pegboard hooks! 

    Also, I had a couple of additional questions (a customer survey if you will). 

    • Do they fit ok all along the backsplash? See above.
    • Is the finish better/worse than you expected for
      a printed part?
    • Is the part as strong as you expected?
      Stronger/weaker?
    • Are you overall satisfied with the part?
    • Would you buy other printed parts if their
      quality matched this one?

    Thanks!

  6. Hi Tyler, great idea!! 

     

    You might choose to “share your project” (ie CAD model) for those of us outside the USA who have our own 3D printers as well Laugh

     

    Cheers,
    Matt

  7. Sure Matt, I can send you the sketchup file (sorry, that's what I used to design it). Or I could send you the .stl file in a PM. What 3D printer do you have? I'm happy to give it to members that have 3D printers, but I'd rather PM the files than post them.

  8. Tyler – Received the tool holder hangers today and I'm impressed by the finish on them. I didn't expect that from a 3-D printer (although I don't have any experience with them). They do fit differently along the length of the backsplash because of its varying thickness along the top. I found that even with the shims you provided, I couldn't get them to fit snugly, so I made some thicker shims using rubberized gasket material attached with double-sided tape. Now they fit better. They do tend to lift off the back-splash when I remove a holder from them, though, so I think I'll try drilling and tapping a hole through the face of the hanger so that a set screw can be installed, coming out of the rear of the hanger right below the back-splash fold-over. That will make the hangers captive so they can't lift off, yet they can still be slid to new positions if desired. 

    To answer your other questions: I would buy other “printed” parts, they are quite strong enough  for this purpose, I'm satisfied with the parts and I'm glad to have them.

    Thanks for a great product, priced right and delivered quickly.

  9. Hi Cutter, thanks for following up. 

    I'm bummed that they don't fit perfectly. I tried hard to find a width that was a happy-medium for my lathe's backsplash dimensions in the hopes that it would be a good fit for everyones G0602. I've sent a few dozen clips out and from the people I've heard back from the fit has ranged from perfect to almost perfect, but fixable with shims. You were the first that had an issue with them lifting up during use that couldn't be fixed with a shim of a few thousandths, which is why I included the adhesive shims. 

    But I like your idea and I might try to re-design them. If I do I'd be happy to send you replacements if you cant get yours to fit right. 

    Anyway, I'm glad that you'd be interested in future products. That's what I like to hear! I've got several ideas for future products, I just have to find the time to turn them into a reality.

    Thanks again for the feedback!

    Hi Tyler, sorry for the tardy reply, a Sketchup file via PM is fine (I use Sketchup extensively as well).  I've got an eMaker Huxley which I'm currently in the middle of assembling…so a “real” and “useful” print job like your tool holder brackets would be great.

    Thanks!

  11. Got my 3D printed QCTP tool holders today – they are NICE!

    The fit is just fine – just pressed to splash panel and hung tools.

    I was impressed with finish – Tyler, I thought you were not printing these solid, sure seem solid to me?

    Plenty strong – just right.

    I'm very satisfied with product and will be watching to see what other goodies you come up with.  Just having something “printed” is neat – like in Star Trek<:)

    Ken H>

  12. Excellent to hear Ken, thanks for the feedback!

    And they made it from Seattle to Alabama very quickly. I sent them Monday the 19th and you had them by the 21st. Who says USPS can't be quick?!

    You're correct, they aren't solid. That would add a lot of plastic (and print time) without adding to the strength of the part. Instead, they are printed with a sort of honeycomb fill that makes them very strong without wasting plastic and print time. Similar to how cardboard is strong because it has corrugations, yet still very light.

    I'm glad you're happy with them. I'm working on another accessory for the G0602, but it's stretching the limits of the size of the print bed. So I need to either figure out a way to shrink it a bit, or build a larger printer.

    But I'll get it sorted eventually.  

    Anyway, enjoy the clips. And remember, if anything ever happens to one (it gets damaged or fails in some way) let me know and I'll send you a replacement. Thanks for the business!

  13. Tyler,

    Are you still selling these on eBay, or are they available to purchase somewhere on the Projects in Metal website?

    Titaniumboy

  14. They are available via this link to the original blog post. Eventually (when I have more than 1 product to sell) I'll have a “Store” section. But for now it's just via the original blog post. 

    At the bottom of the post you should see a yellow/gold paypal “Buy Now” button. They are $7 each. 

    How many were you interested in? I have 3 that are ready to ship, but I can print more if you want a set of 4 or 5. It'll only take an hour or two to print them.

     

     

  15. Hi Tyler,

    I would be interested in anywhere from 2 to 4 QCTP holders, depending on what is the most cost effective number to ship.  Also, is there a volume discount?Smile

    Did you ever post the .stl or sketchup file for these holders?  If so, I think it would be cool to take the file to school and see of the instructor will agree to print these out on the Stratasys 3D printer that they have.  It will be interesting to see the quality differences (if any) between the low cost MakerBot and the $20,000 – $35,000 commercial printer.  The commercial 3D printer still is only able to print to 0.010″ resolution.

    The sketchup file would be more for my use when (if) I ever get a 3D printer.  The printer at school would definitely need the .stl file.

     

    Titaniumboy

  16. The bubble mailer I use will fit up to 6 clips. The shipping cost for any quantity is $4 total. So while there isn't a volume discount, the shipping stays the same for 1 or 100 clips. 

    On average it has cost between $2 and $4 in shipping, plus $0.70 for the envelope. The total depends on the distance and the weight of the package. So I seem to “break-even” at at $4, which is still cheaper than the smallest flat-rate box (which is $4.75). There is no “handling” charge. Just shipping. They're not all that hard to pack. Smile

    And the shipping quoted is for USA orders. Orders outside the USA will require some adjustment depending on where they are going. 

    I can send you the STL and Sketchup files in a PM if you like. Just let me know.

  17. Tyler,

    Thanks for the Sketchup and .stl files.  I’ll see what I can do with them in class this week.  My Solidworks class is tomorrow night so I should know soon whether I’ll be able to print this at school.

    I ended up buying four holders through your new Store last night.  I wonder if I have the honor of being your first “official” Store customer?

    Thanks again.

     

    Titaniumboy

  18. Yes indeed! You were the first official customer to order using the “Store” tab. I should keep a list of the first 300 customers and give you a special badge for the forum, like “Spartan”. Or is that too cheesy?

    But I think it’d be cool to somehow thank the first batch of real customers. After all, you guys are buying things from a new company with no customer reviews or feedback to guide your decision. You should be rewarded for taking a chance. If you have a better idea, let me know. Maybe something like the list of “Top Posters” that shows up at the bottom of the forum. But instead of “Top Posters” it could be “Top Customers”. I don’t know. I’ll keep thinking.

    Anyway, thank you for your business!

  19. Tyler:

     

    I just received my tool-holder brackets, and they work great!  I’m very happy with them, and they have allowed me to free-up some drawer space.  3-D printed parts are so cool!  Keep up the good work, and design some more clever devices that you can “print-out” for us!

     

    Thanks,

    Bruce.

  20. I got mine in yesterday. these are great. 5 of them are now fitted long the back of my lathe. such a better method than I was using. they are up there securely and now i have no worries about busting any more carbide inserts from falling tools. great product…. just wish my lathe was longer so I could mount more

  21. Glad to hear you’re both enjoying your clips! I’ve just added a new product to the store page and I’ve got a few other things in the works. I’ll keep you posted.

  22. Tyler,

    Nice job on the holders.

    Curious, how long does this take you to print.  

    Have you considered just pouring them into a silicone mold? The Material you could/would use would be urethane based.

    VERY VERY tough stuff . Easy to do and the materials can be had most anywhere.

    I just mentioned this because thats what I use for most of my projects. perhaps the urethane might end up costing more

    but once poured, your pulling a part out in less then 30 mins. you could pour several, or even dozens at a time. 

    I started out using the urethane as a way to build inexpensive molds for my thermo former. (2’x6′) 

    Feel free to contact me if you have any questions..

    Sam 

  23. Hi Sam, I have considered a silicone mold, but I’ve only worked with silicone molds once (I made some soap molds for my wife who makes her own soap). 

    For that project I had a friends help who’s an experienced moldmaker. He’s since moved and I’ve lost contact with him. 

    The parts take about 1.5 hours each to print. I print them 4 at a time (since that’s what fits on the printing bed). So I run a batch before I go to bed, then another when I get up, and then a third when I get home. So I can print about 12 in 24 hours. But I like the idea of molding them instead. Especially if I made a half dozen molds and mixed up a large batch of urethane.

    How much does the eurethane cost? Is it by the ounce?

    And the silicone? I think we used about $100 in silicone to make the two trays we made for soap, but I don’t know if I’d use the same kind, or a different kind for urethane.

    So yes, I’d love to pick your brain further. You’re not by any chance in the seattle area are you? That’d be just too convenient! I’m not that lucky.

  24. Tyler,

    No, unfortunately for you Im not in Seattle, Tampa bay ….

    My wife is from Vancouver Ca. but that doesn’t help at all huh!?… Moving on. Like just about everything  You can purchase urethane from many place’s and varieties. the product I use comes in 1 gallon kits and last i recall is about $60 produces about 1.2 gallons in volume. dries to working / handling in about 15 mins. very tough stuff. I have been through about 15 gallons of the stuff.

    Ill look up the vendor (Bcc products)info and send it to you. (I use the quick cast line) and yes your right you could make a silicone mold that holds say 6,7,8 heck 2 dozen parts. then pour all of them at once.  the finished product would only require, IF (and this is a maybe ) the removal of the spur. 

    time would be cut into a fraction of your current time. another thing to keep in mind is the cost of the silicone yes its quite pricey and won’t last forever, but its totally recycle-able. so no real lost $$. I just did a steering wheel for my truck…I prob spent a total of 150. in all of my chems and parts. no labor of course. but it came out sweet. as a lot of my other projects. Steering wheel link here

     Link is at my Apple me gallery (apple is killing this service in another 2 weeks.) so the link won’t last long.

    While Injection molding would of course be the best solution it also requires the greatest investment…. Im guessing 10-15K minimum? likely more. so while the pouring solution might be a little more costly. it saves tons of time and will without a doubt produce a stronger part. their are a few things you can do to save on material. like fill the cavity with another agent to displace the urethane. etc…  

    anyways tho should keep your busy for at least a few mins eh? ha.

    PM or fire me an email Ill give you my # if it helps.

     

    Sam

  25. Hi Sam, back from Victoria, so I can finally reply. Your steering wheel looks excellent! You put a lot of work into it, but it looks great. And knowing ford, you probably saved a grand or more on buying a new wheel (if they even sell a replacement).

    One thing you said puzzled me. Silicone is recycle-able? How? Once it’s set I figured that it was not reusable. Is that not the case?

    We should probably move this conversation to a new post to keep this post on topic. Any interest in doing a writeup on mold making?

  26. Tyler,

    I sent you a pm. like you said I think our conversation was getting off topic.. :)

     

    Sam

    One thing you said puzzled me. Silicone is recycle-able? How? Once it’s set I figured that it was not reusable. Is that not the case?

     

    Example:

    lets say your pouring a 12″ cube so thats 12x12x12 minus the cavity but lets assume their is no cavity. (just for the sake of this recycle-able explanation.)

    you can take some silicon that was used from another/previous project. and even the silicone you scraped up from previous pours, cleanup material overflow material etc…. and recycle it back in the next pour.

    most people will grind it up (say using a meat grinder but optional) then mix it in with the pour.  Each mold is different and has or will probably have different requirements. The thing to remember is you can use the previously kicked off silicone to displace some of the next pour. So if you had half of that in volume then the next pour should only require enough silicone to fill a 6″ cube. saving you some $$

    I hope I explained this correctly.

     

    Sam

     

     

     

  28. Thanks Sam, that makes sense. I hadn’t thought of recycling it by using it as filler. Thanks for explaining! I got your PM also.
