Added ER-40 Collet Chuck to PM-1022V

[twowhites]

Honestly, I'm not sure how much time I have into it. It was a fairly long build, mostly because I don't get a ton of time to mess around in the shop. I would guess around 40 hours of shop time, mostly because I spent way too long trying to find ways to hold things and plan ahead for the next operation. I attached a DXF of a little gasket I drew and laser cut for mine. It might come in handy even just as a template for the drilling for the cover. Though you might want to expand it a little. Mine had an extra page suggesting it might be needed. I thought mine would be ok, but I ended up breaking through on one screw hole. There are enough that it's not a big issue, but it's something to be aware of. I think I was about 0.050 off. lol. Owell.

Overall, it is a lot of fun to build and a useful machine for a home shop. I've used it on a few projects now and it's worked great.

I found a pic of it mounted to a board along with the motor and controller from the treadmill. I kept the flywheel from the treadmill and cut the blank pulley from MLA to match. I did that as the multi-V belts they use are able to handle a smaller drive pulley, so the reduction is higher. The motor is speced for 10,000 RPM, so I wanted to slow the filer down. Keeping the flywheel also keeps the fan that is designed into it. These motors tend to like to be cooled. I think the original belt was broken, I got this one from Amazon.

More great information. Yeah, I'm looking forward to some square metal holes. Thanks for the gasket drawing. It will be very useful.

Tri fly dual contact r8 shank | Shrum Solutions

This face mill gives similar performance to a fly cutter but it can shoulder also. We have brought dual contact r8 performance to the tri fly. 2in diameter 3flute with a 3/4 shank made from a solid bar of 4140. Great for low Hp machines or any thin work piece needing a good finish. Cutting force...

I have this as well as the SuperFly that David linked to. I like both, but if I were to have just one I would take the Tri Fly. I often run it with just one cutter installed instead of all three. The SuperFly will cut a larger diameter on the face, but the Tri Fly will cut to a shoulder.

It's nice to have options!

I did order the Shrum Tri Fly today after chatting with the owner. Blondihacks used it with good success on a cast iron project so I'll give it a try. Thanks for the recommendation.

The tri-fly looks interesting. I have the superfly and love it. I'm probably the odd guy out but I love fly cutters. Have you put an indicator on the tips of each carbide insert on your tri-fly and checked them for consistency?

I haven’t done that, maybe I’ll check it out. Too many projects going now that the snow has melted and the grass is growing!

I finally got the die filer casting secured and made the first passes with the Tri-fly. Looking good so far (famous last words).

I just added a low profile ER-40 collet chuck to my PM-1022V. I got the back plate from Precision Mathews, the collet chuck from Shars (PM didn't carry one, but their helpful folks pointed me in the right direction) and got the box of collets from LMS. I "needed" the collet chuck for the Turnado freehand metal turning system on order. The collet chuck setup is much lighter than the 3 & 4 jaw chucks - the lathe actually runs a little quieter with the reduced chuck weight. (The gears got a bit noisier after my recent change gear swaps for thread cutting.)

Have you received the Turnado, and does your ER-40 collet chuck fit over the Turnado table (by enough that the shoe can pass under it)?

The Eccentric Engineering site mentions an ER-32 collet chuck they designed to "minimize catch points" (though I don't see any details or way to order it on that site), so I wondered whether the larger OD of an ER-40 collet chuck would be too large to fit over the Turnado table.

Also, how long did it take to get the back plate from PM? (Quinn Dunki [aka Blondihacks] said that it's been backordered as long as she's been machining.)
And if would be so good as to confirm whether the collet chuck you got from Shars is their SKU# 202-1029.
The PM site now offers a ER-40 collet chuck; I presume that either it wasn't available when you were looking, or you didn't pick it due to the D1-4 Camlock Mounting.

Thanks in advance for you your time (and sorry for not including URLs to the items mentioned, I'm still in the newbie probation period)...

I have a Turnado setup. It's great. It can work with ER40, but the nut is a little large and can make it difficult to get everything set up. I got an MT3 to ER32 adapter and a few collets for when I need more clearance. It's come in handy for a few other things as well. You do need to make a drawbar to hold it in the spindle, but that can be as simple as threaded rod and hardware. If your main use for collets is the Turnado, go for the ER32. And don't spend a ton on them. For workholding, you don't need the best collets. Just make sure to clean any chips out of the lower quality collets.

My ER40 setup is from Shars, a D1-4 backplate and set-tru chuck. It looks like the one you mentioned. Nice setup, I would think PM would be as well.

I use the PM ER40 with the D1-4 attachment on my PM-1130v. About 90% of the time I'm using the lathe. Only reason I put a chuck on is if the work is too large or needs to be eccentrically mounted.

Collet chuck is easier to use, doesn't have big chucks of metal sticking out to run into tooling or flesh, and generally holds parts concentrically w/o having to tap things in.

The PM version has set screws that allow "truing up" the collet by pushing it around on the mount a few thousandths of an inch.
