OK, I've been told not to use the drill chuck on my HF multi machine to hold mill cutters, so how do I mount mill cutters? Thanks in advance, folks. Appreciate everyone's patience. The only dumb question is the one I DON'T ask! :)

When you say multi machine are you referring to an actual mill, or to a HF drill press. If it's a drill press you don't want to use a drill chuck to hold end mills because the side load exerted on the chuck when milling can cause the jacobs taper to come loose. If it's an actuall milling machine, why not use collets to hold the end mill? Do you have collets?

So if I understand correctly... :) , I need a set of collets which match the MT of the mill/drill press head spindle? Recommended brands/suppliers? Range of collet sizes which will be most useful? Thanks in advance.

Are you sure that the mill has a morse taper? Does the manual call out the taper or describe it in any way? Does your mill have a draw bar that would allow you to secure a collet? There are all kinds of mills, but the only type I've ever used had a draw bar that went into the end of a collet. With the mill off, you inserted the collet into the spindle and tightened the threaded draw bar - causing the collet to be drawn firmly into the spindle. To loosen and remove you turned off the mill, losened the draw bar, and tapped the top of the draw bar to pop the collet out.

However, you mentioned in a different post that your mill came with a drift to dislodge the tooling. That sounds more like a morse taper setup since a drift isn't used with a draw bar.

I guess at this point pictures would help. I just don't have enough experience with all the different types of machines out there to know exactly what you're describing without seeing it.

If you don't have any pictures do you have a link to the machine somewhere on the web? Hopefully one that provides specs. Sorry I'm not more help. Hopefully once I see some pictures I can point you in the right direction.

I

've ordered a MT #2 collet set from Little Machine Shop - should be here today or tomorrow. From my Grandfather's stuff, I have a number of various mill cutters. , but, since my mill is part of a HF 3-in-1 mill/lathe/drill press machine HF #5980 - can't seem to make the &*%$# computer add a pic of the machine to this post - tried following the instructions in the FAQ re uploading pics, but the computer HATES me! :)],  I still need a milling vise. My local, venerable HF store has several different sizes of these. My question is, what size should I buy? Part of me sez 'buy the biggest, it will do the smaller jobs too.'  But then another part of me sez, 'get the one with the finest tpi / best quality 'feed screws' [is that the correct term? But ya know what I'm talking about :)] so they will give the best control of the milling operation.  I know I can expand the capacity of a vise by making a set of "squared 'S' jaws" - huummm..... maybe when the dust settles, I'll have to do this as a project itself & share the plans :).

     Anyway, thanks in advance for any advice from anyone here.

Hi Don, would you be willing to send me a private message with your phone number and the best time to call you? I'd really like to try and figure out why you're having trouble uploading pictures to the site. I know it's not all that user friendly, but I'd like to help you get things sorted out so you can start sharing pictures of your projects and your setup.

As far as the vise is concerned, I wouldn't skimp on the quality of your vise. You probably don't need a Kurt (although you'd certainly be happy with one) but you don't want a cheap vise either. I bought a vise from HF and took it back the same day. It just wasn't any good. 

I'd check ebay for a quality used vise before I'd pay for a new one. There are tons of them listed every week. Some for a very good price. If the seller is willing to ship them in a flat rate box shipping should be around $10. 

As far as the size is concerned, that's a somewhat personal choice. For instance, I think this vise is too large for this mill setup, but the owner is happy with it. I would hate how it hangs so far out over the edge of the table.

So really my only reccommendation would be to find a vise of decent quality that fits your mill (isn't too small or too large). I wouldn't worry abou the TPI of the vise screw. As long as the jaws close nice and tight, that's all you really need. I guess I'm not too much help. Sorry about that.

You might want to hold off until next month. I have a post coming up (it's scheduled to post on the evening of 6/11) for making your own versitile vise. Here's what it looks like.

Here's another view.

The vise is unique because it can be enlarged to as large as your table is long in the X direction. Pretty versatile if you ask me.

If you're really interested in the vise and you can't wait until 6/11 for it to post let me know and I'll send you the plans.

OK, the set of MT #2 collets to secure the mill cutters arrived from Little Machine Shop today... huummm... still have the problem of a 'milling vise' to move the work beneath the cutter. Thanks Tyler for your input re the HF vises. Will anxiously await the plans next month for your vise.  Had actually thought about acquiring or making a low-profile vise to bolt onth the cross-slide of my lathe to use under the mill head.  Think maybe I've unraveled the mystery of posting pics... after all, I WAS able to post an avatar to my profile!!! [which is a major computer accomplishment for me BTW!! :):)] So here is my machine, which will make much more sense than me using a bazillion words :)

I see the avatar, but not the mill.

Yeah, foiled by the evil computer again... but as Tina Turner said in 'Beyond Thunderdome,'  "We shall prevail!" :) Hey, I'm pretty sure I'm smarter than the pic... :) even if the 'puter wins sometimes!! :)  Per U.S Navy tradition, "I have not yet begun to fight!" Besides, [so far anyway :)] I manage to get the math question right so I can post the replies without removing my socks... :)
