A Vertical Milling Attachment for the Atlas Horizontal Mill – Better than the Marvin?

Wednesday, August 18th, 2010

John Lawson invited me over to his shop a few days ago and showed me some pretty amazing things he’s made over the years, including his Atlas vertical milling attachment that he made from Taig parts. His vertical attachment really caught my eye because I am in the process of restoring an Atlas MFC mill and I’ve been looking for a good vertical option for a while now. I think the design is in some ways an improvement over the Marvin milling attachment. Apparently John got the idea when he saw a Taig mill being parted out on eBay. He bought the spindle and motor for a fraction of what a Taig mill costs new and he had everything he needed (except for a mounting plate which he made) for his conversion.

Here’s a video of the attachment in action.

And here are a few pics.

I know what some of you Atlas purists are thinking. “How could anything be better than a Marvin?!” Well, for one thing, it’s available. I’ve never seen a Marving on eBay or anywhere else for sale (although they do supposedly show up for sale occassionally). And I’ve heard that when Marvin milling attachments do show up for sale they cost a fortune. Unless you’re a collector the Marvin isn’t practical. John’s attachment is.

Got a better idea for a vertical milling attachment conversion for an Atlas (or similar) horizontal mill? Share it with us by visiting the forum and leaving a comment/pictures/etc. We’d love to see it!

Video: An Introduction to Stones in the Machine Shop

Thursday, July 22nd, 2010

Barry Young (author of the “Norman Newguy” column) walks us through the various stones he keeps in his tool box. His stones range from rare Hard Arkansas to cheap dollar store stones. Barry not only discusses different stones and their uses, he also explains how to flatten badly worn stones, how to tell natural stone from man-made, etc. He also gives us his recommendation for the first stone a hobby machinist should buy.

You’ll also get a little humor along the way – something that is usually missing from most machining-related videos. What stones do you have in your toolbox? Feel free to add your “two cents” by visiting the forum topic related to this video.

Enjoy!

For The Man Who Has Everything: A V8 Snowblower

Friday, February 26th, 2010

My friend Duff sent me a link to this gizmag article from 2005. It’s a few years old now so some of you may have already seen it but I just had to re-post it. It’s a truly amazing hunk of machinery! Here’s the excerpt from the original article, see the bottom of the post for the link back to gizmag.

If you’re tired of anemic, one-lung snowblowers with their slipping drive belts, you might consider Kai Grundt’s V8 snow blower which raises the bar on the traditional snow blower in every respect. With electric start, electric block heater, antifreeze heater and eight cylinders, it has no drive belts to freeze up and you’ll never get bored with the job as the 454 cubic inch big block Chevrolet V8 produces 412 horsepower, 430 foot pounds of torque and can throw snow 50 feet at just 3500 rpm. Nor will you get cold as the machine has been ingeniously designed to route the engine coolant through the handle bars, with the rear mounted, enclosed radiator keeping the operator nice and cosy.


The first point to make is that this is not a V8 grafted on a traditional snow blower carriage but a purpose-built unit crafted around a motor of this magnitude. It functions very much like a traditional blower by way of operator input and feedback and offers effortless safe operation.

Manouevering the massive beastie (it has a total wet weight of 912lbs) is a snack thanks to the hydraulic-drive 4WD skid steer on independent walking beams which offers a zero turning radius. It’s also as fast as you like, with an infinitely adjustable speed range on the drive wheels via dash mounted flow control. At the opposite end of the scale, it has more than enough torque to pull your car out of the ditch before the hydraulic motors stall!


Adding to the well-balanced feel of the unit, just 15 pounds of down force on the handlebars will lift the auger blade off the ground in order to climb stairs/walkways for ease of snow removal. Safety has and continues to be paramount with spring return to centre “fail safe” type directional controls with emergency stop and tether cords.

Safety is one of the key theme, with a flashing blue light (as required by law in many areas) being the least of the safety features. No-one will fail to hear you with those twin throaty exhausts, which come standard with 92 decibels at the controls, though if the rhumba of a V8 exhaust is music to your ears, you can obviously go much louder. Evan at the standard baffling, hearing protection is strongly suggested.

The powerful yard machine lights and a dashboard with backlit gauges complete the package to ease the burden of this normally reviled task

The custom 42 inch, two stage auger has a Chevrolet 10 bolt truck differential with spool and a centrifugal auger clutch with shear pin protection, further adding to the image of this “automotive theme blower.” As each unit is cutom-built, optional extras for the snowblower are both diverse and outrageous as the base unit – there is unlimited auger choices from single to multi stage designs and various motor combinations to suit the religious preferences of the customer (Chevy, Dodge Hemi, Ford) and such exotica as a V-10 or a diesel engine or remote starting can be accommodated.

And if, after a while, you feel you’ve outgrown the 400 horses, this particular engine is well catered for in the performance modification area, with Lunati camshaft, Milodon Gear drive, Holley and Edelbrock components to name a few, and there’s always the fuel injection option too, if you feel you need to throw the snow out of the county or ensure your seat in the “neighborhood blower blingster hall of fame.”

Here’s the link to the original gizmag article. Sorry for the off-topic post, but I couldn’t resist.
