Yesterday I had to have a larger bullnose live center so I had to do what I have put off for years. I used a chunk of 1045 and machined all surfaces in one chucking. That was the only way I had to get all surfaces concentric. It was time consuming and a bit of a bugger and it took about 6 hours.
The inner taper has a relieved area half the length of the taper so only the front end of the taper aligns with the bullnose center. That makes the press fit ID align with the OD of the bullnose and the end of the bullnose align with the outer end of the adapter to eliminate any possible mismatch.
Went to a farm auction (I love those things). Did my best to stay out of the junk box lots. Got a bunch of scrap steel plate(smaller 12x12" ish 1/2"), some channel, and a couple big pieces of 4" angle for $30. Bought a bunch of old log chains, kept the best ones, and horse traded the scrap ones for some more channel (to the scrapper who bought the rest). Got enough channel now to build a press, and a good small log trailer for the bush. Good day, and good haul for me. Now I gotta go cut the grass, wife just got home
Everything came as scrap from a local shop. The holes had been incorrectly placed in the 4"x5"x3/16" tubing. The 2 1/2"x3/16" angles had been cut to the wrong length. The 3/8" super-flat plate leftovers weren't large enough for the jobs they had planned in the near future.
Now we have a 80"x56" fabrication table that's really flat and sturdy.

Local kid in the scholastic trap league dropped off his shotgun with a rusted interior to the magazine tube from the last time he shot out in the rain. Disassembled, used a brake cylinder hone to clean it up, and put back together so that he can shoot tomorrow. Remembered why I REALLY don't like the Browning Pump Shotgun. Hope it will be another ten years before I have another to work on.

Winchman,
Nice job on the fab table. What is all of that flat stuff arount the legs? Is that what is known as floor space. Gotta get some more of that.

BETTER TO HAVE TOOLS YOU DON'T NEED THAN TO NEED TOOLS YOU DON'T HAVE
A fellow brought in this old backhoe bucket the other day.
One tooth was completely missing, one bushing was gone, and he needed a new pin to mount in on the hoe arm.
We had some old teeth foff a trackhoe, and I cut one of them down to sorta fit as a replacement. Two pieces of scrap plate filled in the voids.
I machined a new bushing from a large brass nut which I had lengthened by adding brazing filler rod to one end. The pin itself was amde from scrap tooling shafts. The washer on the end that's bolted in place has a dowel to keep it from turning and loosening the nut.

Actual progress on the lathe, got the bed fastened and leveled (screws way, way better than shims ), empty headstock installed, countershaft support/stand close to done and in primer.
Now trying to decide what photo service to use so I can post pictures here [photobucket does not seem to be the stellar product it once was, so thinking ImageShack...]
We are installing a new tiller handle on my friends sailboat. Someone gave him a tiller extension minus the mating socket, so I turned one out of stainless:
