So you think converting a Pin-On to QA is Easy!

Hey neighbor, good to hear from you, hope those chain on forks are working out for you.

Got a late start today on reinforcing the bottom of the QA adaptor, by the time I got bevels
cut on the little 3 inch pieces of 3/8 steel it was getting dark out. And by the time
I got them welded on, I could not see the welds very well by the back yard light. No excuse
for my crappy welding technique, but I think they will hold OK.
The mosquito's were chewing on me, and one went by my ear that sounded like a Pratt & Whitney
Whirlwind or something. We have had a lot rain for months, and the Mosquito's are fat and sassy!
Anyway, All that is left is the top 4 ft. by 3 inch 3/8 piece of steel and the hooks on top of
that and some orange paint and the thing will be finished! Thanks for looking.

Welding is generally fun; but grinding welds absolutely sucks.

Here is shown lots of grinding, weld up the holes and cutting scars, and lots of measuring
and more cutting of the center support, to allow the central bottom bar to slide under the
original center stiffener angle metal. This was finally ready to weld, and the top of the QA
unit is resting against some clamped on plates which will be replaced by a 3 inch x 3/8 X 4
foot top support metal bar. I dont have the metal, and will have to purchase that. There will
also be 3 inch x 3/8 supports welded to the bottom for stiffening while back dragging, I was
just too tired today to finish even the bottom supports.
It was very hot and humid today. Besides the wife wanted me to quit and eat supper with her.
So There it sets, not finished, but a lot further along than it was. 7 or 8 cutting wheels,
ran nearly out of gas on the little torch, so used the wheels on the second half, One 7 inch
grinding wheel, one 4 inch grinding wheel, lots of 7018 rods, and used 7014 for the scar and
hole filling. I will post back when it is all done. Thanks for looking.

Have you ever tried "slicer wheels" they're available in 4" or 6" diameter 1/16" thick. That is my favorite demo/steel cutting tool. They cut fast and super accurate. Since I don't have a plasma cutter many times when fabricating it's just as fast to cut 1/4" and under steel with the slicer wheel. Usually when I cut with a torch I cut a little larger and grind to fit. With the slicer wheel I cut to fit no grinding needed.

If you use a slicer wheel just make sure you get a clear ballistic rated full face shield in addition to your normal safety glasses to wear. I've seen a guy bind up a wheel running full speed and it shattered and sliced his neck, 150+ stitches.

Great job sticking with the demo portion of the project. :thumbsup:

I share your frustration...

I needed to bend some 3/8" plate the other day. I thought no problem let me break out this rosebud torch I found at a yard sale. That will heat it up real fast. I dusted off the torch, took it apart, cleaned the tip checked the O-rings, hooked up the gas lines. Every time I ignited the rosebud it back fired about as loud as a 45 round going off. When I did get it to burn I noticed that the tip body was changing color.....OOOH****it's burning inside the tip body. Shut everything down get the model number off the rosebud tip body and the torch body. I went to the Victor website to download operators manual. the torch is so old I guess they don't have any literature for it.

But I did learn a lot from the website. For a number 12 rosebud you need 3/8" diameter Oyx/Acy hose, Large regulators, and a REALLY large Acetylene bottle. Of course I have none of the above. So I ended up using the largest welding tip to heat the plate up.

I know what you went through! Those buckets are very well made; apparently Kubota doesn't believe in stitch welds

Dad and I did his with 5 inch grinders and cut off wheels (1/16). I think it took two of us about an hour to get the bucket cleaned off:laughing:

I used 7 or 8 of those slicing wheels, (with a full face shield) I used some on the 4 inch and some on the 4 1/2 inch grinder. the 4 1/2 was a little better with a little more reach under the edge. A 5 inch would have been better. Yep knew what your problem was with the rosebud instantly, not enough gas flow, to keep it cool, I cannot run a rosebud on my little torch kit, cannot get enough flow, dangerous situation also on a little torch/bottle.

PITA wasn't it? it looks like you might have done a little better job cutting, and made less gouges in the bucket base metal.:thumbsup:

All I can can is (and I am gonna get flamed for it) I sure am glad JD includes a QA bucket as a standard feature on all of their CUT's....:laughing::laughing::laughing:

Nice job James:thumbsup:

Having built a few J.D. Q/A buckets I will say that weight wise J.D. did a good job when they designed it. Some of the extra weight is integral with the loader, there is not much attached to the bucket, less than 10 lbs. I don't agree with how they reinforced the upper brackets though.

I have a decent size actyelene bottle it's about 3' tall, 8" round, I don't know how many CF it is. I can't just pick it right up...gotta get under it. If you can justify it get a 6" grinder, Metabo makes one that the body is the same size a 4-1/2". Those 6" slicer wheels work very well. Then when they wear down you can use them on your 4-1/2' grinder.
