Probably worth it compared to how you feel?

Here are some of the examples of "expert" machining done.
I had to hack off the corners. Not having a band saw, it took a lot of arm stronging. You can see a still to be hacked one at the lower left.
Here's how it now fits. It wasn't able to be placed into the holes. until after it was corner hacked by me. I do know why it's called a hack saw...
Hard to see, I know, but at the bottom of that slot is supposed to be a mating slot in the bushing so a metal piece can be slid in. That allows the boom pivot pin to free rotate and still be captured. The butt ends whack the hoe box when the boom swings side to side, so external capture is not an option. I don't know how it's going to be resolved at this point.
This is the bolt hole that is supposed to capture the bottom pin for the boom lift cylinder. The bushing is in the bottom of the hole. I will be able to grind off the paint and weld a capture gizmo - once I figure one out.
This is the bottom pin for the swing post. I put the capture device on it. The goof ball tried to weld to the pin without heating it and the weld flaked off, so he just used clips to hold the pin in place, but allowed it to rotate. There is no provision for greasing the housing, so rotating pin = rapid wear.
This is the top pin. I made the abomination of a rotation stop. They were supposed to line bore the 3 supports the pin goes thru (they charged me for it), but didn't. His solution was to grind the pin to get clearance meaning it would only fit in 1 orientation. That's why you see it took 2 attempts to get a strap welded on. The swing post would bind up and not swing the first go round. Goof ball.
These are some of the remaining issues after taking these parts back to be re-worked. They fixed some things - refused to fix these and a few others. Bluntly told me to go away and not bother coming back. Owner of the shop refused to discuss the issues with me. Quite the stunning service. Things they did fix were enlarging the boom pivot bushings from 1.5" to 1.75". (The bushing that is supposed to have the slot). Oh, the guy that did the bushings also MADE THE PIN that goes into the bushing. abcdef-ing idiot.
Due to the extreme "peer pressure", I did go out and work on it...
So, put the finishing touches on the boom lift cylinder and put it in place. Took 2 1/2 hours. Had to pick up the boom to gain clearance to get the cylinder in past the bottom of the swing post. Had every lift implement in place to get the boom up, the box up and then get the stuff in place. In case you want an adrenaline rush, lift 2000# of steel and then horse a 140# 36" stroke 4 1/2" cylinder into place and do most of the horsing under the supported steel. Yikes!
This shows the cylinder and the clearance issue. Solved by lifting the boom. But, lifting the boom makes the box pivot down. So a floor jack is needed under the swing post - further limiting clearance! Had to re-hook the cherry picker 3 times to get enough lift to get it in. Plus had to use compressed air to move the rod in and out to get it lined up and in. Naturally, the rod got rotated some during all this jiggering around making it even more "fun". If you want a lesson in dexterity, manipulate a big cylinder while trying to line up the rod end and slide in the pin. Finally wound up shimming the cylinder body, stepping on the end to pivot it up and down with one foot while twisting around and prying thru the hole on one side with a bar while pushing the pin in from the other side. The only surprise is that I got it in. Here's a pic of the boom up in the air, (Don't mind the mess. A buddy is moving and I got some of his garage "surplus", still need to organize and store it.)
Here is the last picture after 150 minutes of effort to get 2 pins into place!
You can see some of my beautiful black paint on the floor from all the manipulations.

John,
I worked field mechanic on heavy equipment construction long enough to know that doing heavy work without the proper tools and help is dangerous, difficult, time consuming, and sometimes impossible. Do be careful.
There is something about the big iron that gets in your blood though and it is a thrill to me to see this taking shape. Keep pressing step by step. Thanks for bending to "peer pressure."

Yeah, I have all the free will of a Lemming....
I moved the dipper stick to the front of the boom yesterday. Had to move it and remove it a couple times to block up the boom so the cherry picker could slide under it. Need to pick it up and manipulate to get it to fit, doncha know.
Was going to put the dipper cylinder in, but found the rod is able to be moved by hand in and out! It also hisses air thru the packing when pressurized. That's bad. I'll have to take it apart and see what is goofy inside it. I KNOW it can't be the packing rebuild, 'cuz I did that myself. Uh, well, maybe that is the FIRST place to look? Oh well, much easier to do now that after it's together.
Merry Christmas!

Dear Santa, will you please put my Backhoe back into like new condition ?

LOL JB If i had the equipment set up Id machine it for ya per post long long agao.
(welder comment) I think the barn came with a ascetaline torch setup no tanks though. could be a monsterous bulk ascetaline tank. afraid to crack it open to find out though. may find somthing we dont want to know about I have to get somany things built/repaired b4 I can get the welder though. I do plan to go for the good stuff right off though.
(machine shop) If they did that to me they would have complaints aginst them from every possible agency that can make life mizerable for them. I understand mistakes can be made. I do how ever expect the person who made them to make every reasonable effort to fix the mistakes. in your case id be hanging them from their toe nails with the treat of letting my wife solve it. large company exec's fear the wife. since he basically told you to go take a hike it is time to do so right after putting in compliants to every possible place to make it known hes not intrested in customers.
(project) its a beauty I hope things get resolved soon so you can get some good use out o your hard work.

Well got some long awaited parts this week, thought I'd share.
I went to put the dipper stick cylinder on and found that the rod was easy to move. HUH?, that ain't right. After all it was just rebuilt a short while ago. Took it apart and found one set of packing had disintegrated. ?? Took that apart and discovered that the bozo that repacked it put in a stack that was 1 1/8 and not 1.025". OOPS! Turns out I'm the Bozo on this one. He he he. The male end on the VEE stack I put in was too thick. Obvious when you look, but not so much if you're oblivious. Turns out that the thin Male end is not common. Had to search and found a supplier that has the one I needed. (Thread in the hydraulics section on suppliers). Well, got the packings for that cylinder and extras for the cylinders on the other hoe. I know it has a bypassing boom cylinder (no, I didn't rebuild it and mess that one up too!).
Also {finally} got some 7/8-14 bulkhead pass thru nuts. FINALLY. Tried the usual places to get them, hydraulic hose place in town, farm/fleet, Fastenal, Grainger no dice. Found them at Discount Hydraulic Hose. Fastenal wanted 6 bucks for the closest size that didn't fit, but the ones I got that do fit were only $0.75 each. Deal! I only NEED one, but bought 10 as there are some that are fairly buggered up. These are also 306 stainless.
After re-assembling the dipper cylinder, I put it on the end of the boom and moved the dipper into position. Connected the hoses and realized that I had swapped the boom and dipper cylinders. No biggie as they are both 4" and 36" stroke. Except the 180 degree turn around from the cylinder needs to be exact on the dipper. So, took off the one from the boom and put it on the one at the dipper. Went to swap the other way and found that there is a thread bugger in the cylinder that is trying its darnedest to make it cross thread. GRRRRR. Tried all the usual tricks, but to no avail. Have a 7/8-14 bottom tap on the way. Always something.
This evening, I jockeyed the end of the dipper so the pin could slide into place. what a PIA to line up! Especially as the rod was cocked a wee little bit. I hate when I do that. Oh well, it's in and happy now.
The dipper to boom pin has issues and I will be getting a new one made. The old one would probably work, but ....

Yeah, good news on the progress John.
Looks like your almost done now? I hate it when I do what you did, only to find it was my own fault, but hey, **** happens.
Also {finally} got some 7/8-14 bulkhead pass thru nuts. FINALLY. Tried the usual places to get them, hydraulic hose place in town, farm/fleet, Fastenal, Grainger no dice. Found them at Discount Hydraulic Hose.
I didn't know you were looking for those bulkhead items or I would have given you the link to Discount Hydraulics last year. They've got a lot of stuff like that not available at Surplus Center. I use them and some others for many of the Metric adapters I need for my Hoe and tractor.

I was just on Discount hydraulic hose com, and they NO LONGER CARRY the 7/8-14 nut! I am so so so glad I ordered 10 when I only NEEDED 1.
This must be an odd ball size deal!

on edit - I did find them on the site. Just not where my book mark was pointing to. Oops.

John,
Thanks for the update. It's especially nice to hear the good news and progress. It's an overwhelming project, but an inspiration to allot of us. Especially me!!!!
