    One piece, very slick,  that curved corner can be a real buggar to make look good. 

    Thanks grannyknot!

    How about one of your NSX hangin' in the air like garage art?

    Give the guy a finger brake and a MIG and suddenly he thinks he can make stuff. He'll learn.   LOL

    You left out Big Bertha!  Now she’s upset 😕9AB0B293-27F4-450C-BF0E-4BCC85FB288D.jpeg

    Absolutely not. It would set a bad precedent. There are many of us who's first attempt(s) at a project goes.... ummm.... unmentioned.   LOL

    Haha - good point for sure !

    The bead roller started out as a Princess Auto (Harbor Freight basically) special.   It was junk.  I kept the dies and started over.  Gears are from Boston Gear, Motor was pulled from an electric hoist.  It was a fun project on it’s own!

    Well nice work on that bead roller, and nice work on applying the tools you have as well. The metal work that you have been doing is great. Way beyond my pay grade.

    I made a little press brake I use on the hydraulic press... Does that count for anything?   LOL

    Forgot.... So about that gear motor from the electric hoist.

    I'm looking at a project where I want a cheap rotating welding positioner that I will probably only ever use once. How fast does that gear motor spin?

    Hey Captain - the mini brake is fantastic!  I will be copying that!  Plenty of times that I need a 4 inch piece and cand be bothered to drag out the 4 ft bender.

    Making tools is fun - it could become a whole separate (probably expensive) hobby for me.

    It is internally geared to 60 rpm but it was too fast so the large gear brings it down to 10-ish rpm.

    Ok true.  I guess this project actually started sometime in the 90’s 😀

    Oh man... Wrong time for that!

    If you have a TIG, don't bother trying to use the straight argon. Doesn't work well.

    So about my bender...

    That press brake is only maybe eight inches or so long, but I'm very happy with the way it turned out. I saw the idea on the web and made up the details as I went along. Of course, as with most project, the details are where the magic is.

    One longer spring I cut into two halves. Two bolts (5/8-11 I think) with the heads cut off for the guide pins. Nyloc nuts (not in pic) to adjust and hold position for different stock thicknesses. I made the bottom die shorter than the top on purpose so it functions like a finger brake with some of the fingers removed. That way I can hang the unbent portion out of the dies and keep a section straight. Here's a pic of most of the parts before final assy:

    I cut the bolt heads off on the lathe and turned a counterbore shoulder. That way I can press the bolts into the base and the shoulder will make sure they are perpendicular (normal). The shoulder is a little shorter than the base thickness so the bottom is recessed. That way I can tack weld the bolts into place from underneath and the base will still sit flat:
    P1110186.JPG

    I made the dies on my metal shaper. Here's an action shot cutting the first side of the upper die:

    And here's the two finished. They really should be hardened for longer life, but I'm kinda hoping that with the few bends I make, it'll last long enough without heat treat:

    So far it's been a great little tool and has enabled me to make such beauties as this:

    I thought I saw some custom mill work on your mini brake.  Is that a Smithy lathe in the background?  Your brake is a great tool for making all the small brackets.  Thanks for sharing - I wasn’t joking about copying it 😀

    Smithy lathe???   Pshaw!  It's a South Bend.    :beer:   Haha!! How's that for lathe elitist?

    The Monarch guys would all be rolling their eyes... South Bend??? Pshaw! It's a Monarch.  LOL!

    I'd be honored for you to copy all or part of that brake. Let me know if there are any questions. I think the whole thing cost me under $30 US, and I think the only thing I couldn't find at a big box store was the tube for the slides. I'd have to dig out my records, but I believe I ordered a foot or so of DOM tubing for those. The welded stuff at the big box stores wasn't a good enough fit so I think I ordered that.

    South Bend - very nice!  You aren’t playing around! 

    I will take you up on your Q and A offer if needed.  Thanks very much.

    If you surround the welded area with strong magnets, the oxygen atoms are pushed away hence no need for gas..... 🤣
