Zombie thread....

But I used a stock 3 in 1 bender, and got it to work quite well with a few adjustments. They are not bad, just unfinished.

I made one of the OP's 3-in-1 stands. Like him, I used a piece of I-beam (actually W beam). But I left my beam intact for stiffness. Installed and adjusted, the shear cuts very nicely now compared to before. I haven't painted mine yet, will do that when the weather improves. I added a couple pictures below. The guards and table aren't on the machine. - metalmagpie

Hi Group,
Here is my 3-1 after some modifications so that it was easier for me to use. The roller is a tool of it's own, just turn the wheel. The shear and brake are one in the same with a foot stomp operation. This gives me control of the material and the force to shear with control. The claim of 18ga. is still out of reach for the shear but it does cut 22,24,ga. steel full width. I do not have the brake plates installed until I need to use it. The blade clearance to get it to shear has to be about 0 for it to cut. the brake works well on the couple of pieces so far upto 18ga.

If I can answer any questions on the modification fire away.

Resurrecting an old thread but I'm genuinely interested in more details on the mods you made.

I use one of these daily for small production runs. Would be really useful to make these changes.

I cut up to 14 gauge (1.5mm) on it but can form small pieces of 12 gauge (3mm) as it is. Wondering if changes like this would impede this?

In particular, knowing more information on the springs (source, length, gauge?) and how you change from shear to bender without the cam?

Only other issue I have with these is repeat cutting of shamfered angle on sheet, coming up with a suitable jig for each one I have (several designs). I've realised my reliance on magnets, even strong ones, is prone to shifting after several cuts.

TIA

Jon

Great Mods Mr Fixit

Mr Fixit these are great modifications.
I just got one of these 3 in 1's and I like what you have done.
Can you elaborate on some of your process.
Thanks again!

If I right click on what used to be an image and 'open in new tab' it opens up a photobucket window - then right click on that and it opens up the original image.

That doesn't work for me. In Windows IE-11, the "open in new tab" is greyed out and can't be selected.

So you see the images in this thread? I have the Firefox Add-on and only see the "please update your account" speedometer image.

Yep, I see them fine. Don't have to do anything. But one thing I wondered about: apparently the first time I downloaded the fix it somehow didn't install in Firefox.

If it's installed, you should be able select tools > add-ons and see "photobucket embed fix" in the list. I've enabled/disabled it a number of if times testing and it works as expected.

Firefox has an add-on that will allow you to see those PB images.

Curiously enough, all of my pictures are still appearing in old threads, and I have still not gotten an email from Photobucket (that I noticed anyway). Go figure.

I know this thread is old, but since PB mangled this and so many other forums I was wondering if the source or alternate photos for these mods are available.

Ill be working on my 3in1 in the near future and the photos would be super-helpful.

Thanks!

Interesting. On mine the bolt just bears on the support, but doesn't thread into it. Maybe it was a running change. Gives me an idea for a mod to mine, though.

Thanks for looking.

[CCWKen]

Well, you had me wondering since I hadn't adjusted mine in quite a while so I went out to the barn to check. On mine, the bolt threads into the support so I can bow the support in either direction. I sure don't remember drilling and tapping it so it must have come that way. I checked the manual but the drawing shows the "crossbeam" from the other side and just lists the bolt and nut.

[ed_h]

There should be a nut behind the strap. You can see the extended bolt in the picture above--It's not run in all the way. If you tighten the nut against the strap it will pull the ends back (away from the table). To tighten the nut against the strap, you would turn it counterclockwise.

Ken--I just looked at mine. I think it's the same as yours. Yup, there is a nut behind the strap. With this arrangement, as the nut is moved up towards the head of the bolt, the strap is pushed away from the support, which pulls the ends of the top blade back, and pushes the center forward. I don't think it can do the opposite since the bolt is not fastened to the support itself, so it cant pull the center of the support back. That is how mine needed to move to get into line.

Eddy - I'm not sure that would help. If a plate was added to the entire side and incorporated reinforcement to the feet it would help. Simply reinforcing the area between the feet would probably break the feet off during a heavy cut. As force is applied with the upper blade, the reinforced table is rejecting the force causing the lifting stress on the legs. The U-bolt was a Q&D but it seemed to help. Perhaps if a full-length reinforcement was welded to the stand then through bolted to the sides it might help. This would lower the stress on the foot mounts.

Good eye on the existing lower holes. I had forgotten about that. I now remember removing the upper blade support to drill the other holes. That thing was heavy even without adding the 1/2" flat.

Bill McLeod - I can cut full length 20ga. and about 24" of 18ga. I've even cut 6x.015" spring steel but I don't recommend it be frequently. It would probably cut full length 18ga but the motor stalls. The motor was salvaged from a water pump that "claimed" to be 1hp. It's been making bearing noises lately so I'll be on the look-out for 1.5 or 2hp motor.

JJClear - Thanks. I knew I had posted it somewhere. I remember posting it on Metal Meet but after the "The Crash" and other difficulties with MM, a lot of posts were lost. It's been a while since I was back there.
