Mass produce bending jigs or J-parts? Stack 2 pieces of 1/4" flatbar and bend them with the pusher you have. One of the parts will become your u-shaped 'shim'.

Good idea,Sodo. I will have to remember that one.

Shield, used yours (except once when I forgot) and once when I welded both long welds on one side then both inside opposites of those.

Took more pics, will upload later, probably around 5 or 6. (that's "retirement time", got a grain of salt??!? :laughing: )

Sodo, at this rate I'd be money ahead to take a part time job as a Wally-world greeter and hire somebody ELSE to do this, but (in spite of the humor in watching WallyWorld freaks) where's the fun in THAT?

I beveled the inside tops @ 45 degrees, used the bigger table that came with the Jet saw and clamped a cheap plastic "miter guide" from Rockler to the base of the jig, it has a bar that's supposed to fit the miter slot on a table saw - held that bar against the edge of the bandsaw table firmly and pushed the jig into it. Not perfect, but it worked better than trying to keep both sides equal with a side grinder

More later, gotta grab a bite, clean the bumps off the "new" press plates, cut a few "candidates" out of 1/2" stock and find out what "plan G" needs to be

Thanks again for all the help... Steve

Edit - Sodo, at first I didn't get what you meant by your suggestion, didn't think it would work - duh, finally got it. Thanks a LOT... (this isn't "new york sarcasm", BTW)

wider bevels on mouth

setup for first attempt

start of push

20 tons with no lube

slick does the trick

Oops, good thing I made more blanks

Second push, corrected error

Pushing out the finished part

One lonely boo-boo, 4 winners


Observations - I think that if you applied 20 tons + 4 pounds to HF's 20 ton press, you should do it in another county
I think I'd have been in trouble if I hadn't increased the bevel on the mouth of the fixture - also, without lube I would have needed to crank up the rosebud for sure. The first third of the push was easy, then it stalled out - at first, I thought "typical HF jack, probably low on fluid", till I tried pulling on the handle instead of using the air actuator - thought I was gonna break the handle and still no movement.

The fixture flexed a little, but other than that just a slight amount of galling on the top bevels.

I sanded down and broke the edges of each piece before pushing, didn't wanna take the chance on a stress crack boogering up an otherwise good part - don't know if it was necessary, only know nothing bad happened

What fixed the first one's problem? As soon as the pusher comes in full contact with the flat bar, make SURE that the horizontal part of the pusher is EXACTLY square with the bar, and that the pusher is EXACTLY centered over, and SQUARE to, the female jig.

Any questions please feel free to ask, I know I learned sumthin' today and I'm glad to pass it on (go TBN :cool2: )

Tomorrow I'll make some messes with the plaz, Friday the rest of my hydraulic parts get here, it's gonna be a busy week or three

Later... Steve

Oh, forgot to mention - only 3/32" of spring back on those parts, that's perfect for what I'm doing. Upper bucket pin will snug down in the bottom, and the slight flare will make hookup easy...

 

[Big Barn]

Nice job, Steve. And your jig turned out great! After seeing yours pics I realized I'll have to get out the sanding discs and pretty mine up tomorrow. Thanks a bunch! (just kidding ). Good work.

Thanks Terry, that was a fun little "sub project", part of a "system" that's too complex to either accomplish or post all at once - eventually I'll get everything together, it'll include the original (modified) bucket, brush bucket, 6 foot flail, 3PH quick hitch, open frame forklift, articulated hydraulic sickle bar for hedge trim/brush/tree trimming, same linkage but 14" electric chain saw, grapple, and 100 gallon Capuchino machine (OK, I lied about the Capuchino

All the above will have identical pin mounts to the original bucket, so any of them will swap out on the loader arms in maybe 5 minutes - maybe 10 if the new attachment needs hydraulics hooked up.

I have two solenoid diverter valves mounted to a plate that'll attach to the loader cross tube, 3/8 stainless hard tubing from the diverters to a QD jackplate and 3/8 QD's, I'm inserting a 30 gpm flow divider before the loader valve that'll run a small hyd motor (sickle) or a larger one (for the flail) and it's adjustable so I can make sure there's enough Excess flow to run the rest of the hydraulics (but slowly) while the flail is powered, or cut back for the sickle bar and have faster hydraulics for the rest. I've built a sturdy bracket that puts the flow control right next to the loader joystick but out of the way.

The solenoid valves will tie into the bucket curl - no buttons pushed = original curl function, one or the other button switches the curl control to whichever function that diverter is connected to, keeping feathering control for whatever is being used. The buttons mentioned are on a Scorpion industries loader replacement handle.

I have everything I need to run new hard lines for the loader curl, all hoses and fittings, added 3/4" tubing for the hydraulic motor control (QD's for this at the loader attachment point) - Got most of the parts cut out for Case compatible mounts for the grapple (6' wide, 900 pounds sitting on a pallet next to my shop)

And, in my SPARE TIME...

OK, that made me tired just TYPING it :confused2: Gotta go rest now... Steve

Nice job. Good to know that 20T can do that bend on 1/2" steel. BTW where do you get all that polished steel?

 

[BukitCase]

Yeah, 20 ton can do 1/2" 3" wide - don't know if I'd take bets on it doing 3-1/2" wide tho Supposedly it'll do 5" wide for a 90 degree bend.

Where do I get all that polished steel? A sometimes heavy dose of OCD, aided and abetted by CGW flap disks Not to mention 'way too much time on some projects...

Believe it or not, I've actually done a few things I left the mill scale on and didn't paint :laughing:
