Here's my old one that I recently parted with: It's an early 50's Yale KG51-AT 4000# unit with a Chrysler Industrial 30 (230 ci flathead 6) and runs on gas. Here's my 'new' one as I found it. It's up and running after a lot of work: I don't know what year it is - probably 50's...

I had the same issue on my big lathe (20") when I first got it. I did the same as you up to taking a 1" impact to a welded bolt/nut in the chuck to no avail. What finally did it was removing the chuck from the backplate, putting a couple of bolts in the backplate, putting it into back gear and...

Sorry, I should have clarified. That is not my drill press - it's just one that I found on vintagemachinery.org that looks the closest to yours.

Looks like an early Atlas or Dunlap (Sears). It's missing the front pully guard. Possibly a model 51? http://vintagemachinery.org/photoindex/detail.aspx?id=41174

One of the last things to do was clean up the nut that keeps the flywheel on. Coincidently, it looks much the same as the spindle nuts on Dana 44 axles and the socket is a close fit. Like the tension screws, this was mangled by years of the hammer and screwdriver treatment as well: More...

Another big failure of this design are the tension screws that push the pump away from the flywheel to put tension on the drive belts. The overall design is fine but they used large flat drive screw slots. Over time, they became completely destroyed. So, they need a good cleanup and...

So, here's the shaft all welded up and looking pretty gnarly: I increased the diameter from 18mm to 3/4" for more strength. Then I turned it down and had the keyway machined. I also hardened and tempered it back as best I could. We'll see if it lasts. The saving grace is that there is a...

Thanks! I was worried that nobody was interested :). It already has pneumatics all the way around. I used it briefly on the grass and it didn't get stuck at all. I have it back together now and I'll post an update soon.

Quick update - The shaft has been welded up and turned down. It's at the machine shop getting the keyways cut and broached into the pulley. After welding, the shaft turned to butter so I'll need to reharden it. Not knowing exactly what alloy it is, my plan is to heat it to red, quench it in...

I think the way that this is supposed to work is that the flywheel, belts and pump pulley are supposed to slide down onto their respective shafts. I'm certain whomever engineered this is long since dead but they need to be dug up and killed again. This design might have might have worked...

DETOUR! Just when I thought this one was about wrapped up, I tried to lift about 500 lbs and the belts for the hydraulic pump started slipping. No problem - just tighten them up. No more adjustment left...hmmm Ok, it needs new belts. No problem. Wait, how do you get them on and off? I...

Those turned out to be pretty easy to find as well as the proper dust wiper. The rod turned out to be a bit rusty and pitted due to water leaking past the non-existent wiper. So, into the lathe it went: I polished from 80 grit up to 1500. I didn't get all of the pits out, of...

Since the carriage was removed, it was a good time to dig into the lift cylinder. It had a nasty habit of spitting and oozing fluid out of the top gland. Seeing as how its a single acting cylinder (fluid on one side only), this meant that, not only was the gland leaking, the main seals were...

I got all of that put back together only to find that my 90 degree fitting had a small leak due to it not seating properly. So, I pulled it back apart and fixed it. The brakes work now but it's leaking gear oil form somewhere so I'll have to fix that. In the meantime, I decided to tackle the...

For the bleed screw end, I started with an inverted flare coupler and nut and a bleed screw: Bore out the nut to a #3 and thread to 1/4-28: Turn a shoulder onto one end of the coupler, make a bracket and solder it together: The tip of the...

On to the remote bleed screw. from the research that I did, I couldn't find a good OTS solution to this. Apparently, some Jaguars have very inaccessible bleed screws that require special hoses and fittings but those cost more money than I want to spends and would need to be modified. So...

I've moved several sheds ranging from a 5x8 sheet metal garden shed to a 12x8 Tuff-shed. The Tuff-shed was loaded onto a trailer and moved a few miles to my yard. Moving a 10x8 should be pretty straight forward. As others have said, jack it up and roll it on PVC or other piping. When I...

And the drum is turned: Since the OD is as-cast, I had to shim it to get it to run true to the sealing surface in the center. I got it within .004" so that should be more than fine for a forklift that won't go over 5 mph. Something that bothers me about the original design is that the brake...

There are drain holes in the burner pan and the bottom of the pit is open to the pavers.

Last year, I built a patio in our backyard so that we could have a place to enjoy during the summer. One of the last parts to build was the gas fire pit. I am partial to wood fires myself but they can be smoky and the embers tend to damage the patio furniture. So, gas it is! I had my HVAC...
