I’ll keep that in mind if my brother finally talks me into helping him move back to Mi from Phoenix AZ. I am resisting that as much as possible.

Would like to meet a few fellow guys along the way.

But, for bending small thin pieces of metal, it would be fine. I used ash wood, that I got from a friend that been drying for about 10 years. I wish I had pieces thicker than 1” for some projects.

This is how I built my dies for my press, the upper blade has to be over 90 or you can't get a 90 bend

I think you meant to say upper die has to “under” 90 to be able to bend a 90 degree bend. I think the bottom also needs to be a bit under, since you have to account for spring back.

I found out I had to really over bend the lexan sheet in order to overcome the spring back, unless I got it right the first time.

I plan on making several lengths of bottom dies using solid round stock. The upper die will control the radius, and as you are bending, it will start out easily because it will be a wider base. As you go more, the opening will narrow allowing a tighter bend.

I made a setup like this at old job for bending various parts. It works good.

The downside to this setup is its hard to get real close bends to each other.

I'm pretty accessible here, just one block off one of the large streets that are at an exit off I40 About a mile or so North on Juan Tabo and block east of it
I'd enjoy meeting some of "you-all" also. I did meet Cutter on one of our trips through Texas

Brian, Great thread.. Lots of might fine work here..


I go to different forums and see lots of different work.. But each time I come back home,(here) I see mighty impressive work..

I’ve been going to do this a couple years now, and today I finally did it. One of those projects that I really should have done years ago.

I made a spider for the end of spindle on my work lathe. My summit lathe has a 4” thru bore, and has a swing of 20” x 84” bed. It is a fairly good size lathe.

When ever I had a long shaft sticking out the head stock side, would place a stand with roller top under it to support it but most long shafts will have a slight bend in them, and sometimes it like to rock the stand around. So then I have yo usually run the RPMs much slower to avoid whipping the end too bad.

Today I had to start a job of making 2 drive roller from 2-1/4” shaft ( we stock chrome plated rod, so that is what the customer gets. One end I have to turn it 7” down to 1-1/4”, with first 2” being .875”.

Opposite end has almost 12” turned down to 1-1/4” with 2” end being 1” diameter. I also gave to cut 3 keyways after turning.

So today I took just under 2 hours to find the material in house and make a bushing that will fit into the end of the spindle with a good tap fit in, and thread the end for four 1/2-13 threaded rod bolts I made up.

I put the four jaw Chuck on the lathe and dialed in both ends to within .002” runout, checked at 8” and 13” from the respected ends. I figured there is a slight bow in the overall length of the rod, so it the roller would be the best balanced and the ends where the bearings ride will be true to each end by indicating in from each end.

So I had 4’ of 2-1/4” rod unsupported hanging out the back of my lathe. I was running the RPMS at 500, and the end had about .014” runout at that rpm. I was impressed.

The down side to the way I made this spider is that I can only get about 3-1/2” thru the ID.
I was planning on making it so I would have the complete 4” thru open, but that is going to take some modification to the end guard,to be able to attach it to the spindle. There is a safety switch that shuts lathe down if cover is opened, and I don’t really want to bypass that.

So I will see how this works out for now. So far after running it about an hour today, I got the 7” end roughed in to about .001” over. I usually use Emory cloth to finish these shafts, because I like to try to get nice snug slip fits for bearings. I do not like over cutting that last cut, and find out it cut .003”under and have to start over with a new 8’ long piece. Been there, don’t like that place telling the boss I need more material.

Nice!! Looks like the shop is kept clean is that because of you or the boss?

Very nice work Brian, and I noticed the work on the support stand as well

I try harder at work to keep place clean and organized. I think it is a bit better since I started, since I think I’m the one who seems to make the most time to clean. Especially the machines. Before I started, we didn’t know what original color was. Just dirty brown from 20 years of machining.

I figure time spent cleaning does not directly pay the bills, but a dirty shop does lend itself to a piss poor attitude in workers. And if boss brings a customer thru to show off the shop, a cleaner appearance never hurts.

Boss has never said no to time spent cleaning and organizing.

Optical illusion. The stand is just being used to hold my dial indicator for checking runout.
