I picked up this sheet metal press brake a few months ago but it did not have any large bottom dies for bending 1/8 inch metal. lets see what we can build in the garage that can be used as a bottom die,
one mans junk is another mans treasure…

After cutting that 1/2" bar stock length ways with your plasma, you could have just run a torch along the back side and it would have straightened it right back out
For a homemade stamp die,that’s pretty damn good
Now you just chuck a block into your Bridgeport and you have a brand new die set built just the way you need them.😁

You should make a top and bottom die so you can end up with round corners maybe one that can also adapt to different sizes as well, that's was pretty interesting there bud. Good job. mate.
I was writing and not watching your bottom die is way too small and your bolster is loose the die should rest dead bottom and shim with paper or folder paper I would not use allen or metal never weld most bolster s are crowned and some have auto crown and most have a ram tilt adjustment as well that top die is for like 11guauge that bottom is for 18 gauge and there is air bending or kissing but very inconsistent bottom bending you need cnc control for that and coining at the end you were coining or back bending but mismatched dies can get warm/explode
I ran brakes for 20 yrs top is ram bottom is bolster dies should be 6 to 8 times the thickness of material round radius is 1to1/2 and axis brakes and cnc are great when you align the dies first and shim them you will save a lot of time. Be careful even small manual presses like this can be powerful and dangerous
I have 17 years press brake and machine experience any questions ask
Guuu jaaab….
Awesome. Glad that you’ll get some more use out of the brake now! Great to hear you talk through your projects. Thanks for sharing!
A good tip : take a 6" length of 1/2" round rod and weld your Allen wrench to it in the middle and make a heavy duty T-wrench the one I built I let 5" of the Allen stick out after cutting it and Tig welded it so it was smooth this will speed up your die changes.
The ledge on the bottom dies that sit on the die holder top surface allow for shims to compensate for variation in bend angle along the length. If you have an old tape measure you can cut it up into different lengths and add them in areas that are not bending as much. If you add more than a couple shims on top of each other be aware that the die will rock when the top die (punch) pinches the metal. Avoid this by tightening the the allan screws on the bottom die. Nice video!
