No, not too late at all! Do you want to be dipped in it or hit with the bucket? LOL!
Actually, I just sent off a nasty note to the machine shop. They put in 1 3/4 bushings to fit the 1 7/8 pin that connects the boom to the swing post. Guess which side has the wrong size bushings: A) the 100# swing post or B) the 700# boom?
That's right, B - the 700 pound boom with the expensive fresh and still fragile paint.
Someone must have beat me with an "unlucky stick"

WOW, sorry to hear about that. I know how frustrating it can be to have to take it back, but never imagined what dealing with such heavy parts must be like.
Nothing to do but deal with it, sorry to hear this.

Eddie,
Yep, two choices - leave it apart or get it fixed.
I dropped the boom off (42 miles each way) and they are supposed to be done with it Wednesday. The owner was apologetic and the machinist was defensive. As well he should be - I hope that limp was from the boss chewing a large part of the posterior off. My note detailed all of the issues that I was letting slide. One by one, they weren't much - but all together they were a lot. I truely do not like a machinist taking the smoke wrench to bushings and cutting the housing by 1/8 - 1/4". I especially don't like it when that allows the grease to go around the bushing and not get to the pin. The extra slot now has epoxy to hold the grease in. I may not be old, but I am old school.
Funny thing. When I got there, in the back of the lot was a TLB like mine. Only in the "before" shape. The owner had just bought it at auction. I think he paid $3450. Makes me feel pretty good about getting a parts machine in that same condition and spending $1000 for the machine and $400 for 598 miles of delivery.

ARRRRRGGGHGHHH!
Got the call from the machinist today that the bushings were sized correctly and to go get the boom. Went there, and tried the pin in the holes (seemed to be the thing to do).
And.... it didn't fit.
The machinist had POUNDED the pin in with a 5# hand maul and I think he may have mushroomed the head. OK, had him turn it down so it would fit. Noted that the pin was bent a bit (5 mils or so). It would only go in from one side. OK, can do. Had some discussion on how the pin is retained. There is a slot in the pin and a tab is inserted into the slot thru a slot in the bushing/housing. Explained it to the machinist. Actually we took more than 5 min as he didn't get it for a while.
Finally tweaked the pin and bushing so it would fit nice. Mostly took out nicks he put in. OK.
Get the boom home, get it off the trailer and turned around. Ever hung a 700# 10' long freshly painted thing from an engine picker and spun it around in a crowded shop? Take my advice - don't. Certainly don't get in a hurry or the picker may go nose over. You can't see it in the pictures, but there is a 5 gal bucket full of broken gears and such on the back of the engine picker.
OK, moved the boom in, brought the box back, moved the boom into position, raised it up and got everything to align. Slid the pin in 1/2 way and it froze. Checkd and the boom was cocked down a bit. Got a wood stake and levered it up 1/16" from one side and pulled the pin in from the other side. Had to tap it the last 1/4" - not hard nor many taps.
Go to put the tab in the slot that holds the pin.......
NO SLOT CUT IN THE BUSHING.
All I can say is that it is a good thing that the machinist is 40 miles away.....

Has this "machinist" worked on heavy equipment before? At least he used a real hammer to mushroom your pin and not a big rock on a stick. They should be coming to get the boom for you at this point, and the shop owner should be involved now. I don't like to stand over a supposed professional while they work, because I'm not a huge fan of that being done to me, but in return I want a professional job done. Starting with blowing your estimate, and now 2 comebacks, and botched comebacks at that, I would be ashamed if I was involved in that type of work.
Hi,
Been wrapped up with the "other hoe" and not gotten too much done.
I put the stabilizer arm and pads on. The pad pins were worn. No imagine more wear, nope still more --> picture about 3/16" of a 1 1/4" hardened pin being all that is left. Now, that's worn. I found that hitch pins come in 1 1/4" size and are almost long enough. I also found that when you peel off the plastic on the handle, that there is a collar welded on to the rod around the top and the loop is just welded on to that. A quick spin in the chop saw and the collar is now 1/2 as wide as it was and the cheap pins will work. Had to drill a hole and tap it to use a bolt to limit rotation of the pin in the pad. One tap did snap on me. P'ed me O too. Took some gentle work to get it out. Man, I don't like snapping off hard steel! Still, 2 pins for a total of 15 bucks is a lot better than getting some custom pins made!
I also cleaned out the back storage area and hung 3 cylinders, 2 sets of 2-bar links for the swing, 6 control levers, 2 pivot assemblies and slathered on a coat of Corlar 2.1 PR primer. I had trouble getting that stuff to harden up when I last used it, but it went on nice and after 3 hours was dry to the touch. Should be ready for color tomorrow. Isn't it amazing the difference a high of 94F and a low of 80F makes when compared to a high of 70 and a low of 40?

thats ok most of the 20's and younger are probably worse off then you. morons to stupid to know that when some one can hear them a block away they are not going to hear any one in the near future...
tone deff most likely. I have a touch of it for no good reason. I could tell when a capper on the other side of a large factory stopped working but cant hear certin pitches in the normal human language level.. that sucks for the ringing part to.
Awesome job on the equipment. it is a shame all the trouble you have had with that shop. I hope once i get going in my shop I will do half as good as you do.

LOL! Thanks for the compliment, but I have to laugh. I don't think there is anything I have going on over anyone else. There are no special skills involved other than a desire to get the machine into working order, a few tools and a space to work. Anyone with that can do a good job. I'm sure you will, too! Lately my favorite tool has been a 3' pipe to get more leverage!
Two biggest issues are:
1) "mission creep" - where one repair leads to 3 more and each of them leads to 3 more and each of them....
2)an overwhelming sense of drowning. That's mostly due to #1! But, just do each job one by one, take notes, take pictures, buy the manuals and it's pretty easy. Honestly thought, there was much more sense of that when I had the yellow tractor all apart with no two parts bolted together. Looking at the piles of parts gave a sinking sensation at times. But, it's together and working fine.
I did spray on 2 coats of Imron 3.5 HG Black on the cyliders and other parts this evening. The morning and early afternoon were cloudy and looked like it could storm. Cleared up after dinner. I do think that I need to either switch to a lighter color or get some better lighting. It's real hard to see where the black over red primer is too thin. So I hit it again and got some sags. Oh well, it ain't a show queen (fer sure).
