Being a scouter for many years I recognized Keith's belt right away. Keith has worn it in many of his videos. Nice to know Keith is a fellow scouter!

Geez you're really carving it up out here aren't ya 😜🤣 that was a great pun, you got a thumbs up from me lol

Had same sort of joke in my mind 😁😉

I don't think that would be any different than woodworkers branding pieces they make. It would be nice for a future owner to know what was done to a machine and when.

Makes me wonder if these videos will still exist 100 years from now and how hard it will be to find them. What a boon they would be for the next Keith Rucker that comes along.

The instructions from Turcite (spelled with a c not a k) state to make the grooves no deeper than half the thickness of the Turcite. My milling machine had the grooves all the way through from the manufacturer and the way oil destroyed the adhesive bond. When I was reconditioning it the Turcite fell off when I took the machine apart. So on that basis I think Keith screwed up. I cut the new grooves in my machine with a round cutter in a Dremel tool so they had the profile you suggest. I don't know if that profile is better or not.

Yes. If you look closely, you can see that the center of the worm gear is a smaller diameter than the sides. This is so it will wrap around the worm itself, which of course is a cylinder, so the teeth on the matching gear need to be cut cylindrically.

Curious why some rebuilders would have that opinion. I restored my Harding HLVH that included a bed plate regrind. We installed Rulon on the saddle AND the tailstock. The results were remarkable and the accuracy of the machine is better than when it left Elmira back in 1969. The factory taper spec is .0001 in 6 inches. This lathe ended up at less than .0001 in 10 inches. Most, if not all Hardinge rebuilders shim the bed plate, which considerably less time consuming, especially because machining the underside of the tailstock is a workholding challenge.We beat it by designing and building a custom fixture that has pitch and yaw adjustment capability. I am surprised Keith scraped the oil grooves down to the cast iron which exposes the epoxy to the way oil.

It was ground with intent of Turcite being applied. Any grinding shop familiar with the process can figure out the geometry and correctly grind ways to allow for necessary clearance. It’s something you need to plan ahead for, and I’m sure Keith went over dimensions, bed wear, etc with the grind shop so it went together correctly.

The headstock can rise up and down , so that lil' turkite makes no problem. It is a horizontal boring mill , not a lathe or bridgeport mill.

@@bernardwill7196 I think you're missing the point, the studs where the shafts go into don't move with the headstock so you have to get the dimensions right before assembly. But seeing Kenny's comment, I think I forgot about what Keith said about getting the bed ground to a dimension fitting for the turcite. That does answer my question, even though I should have known that already lol...

Does not matter. The head and out board support / tail stock move up and down in sync.

@@CatNolara Ok you are right right and Keith is not an idiot, he know what he did. On the other hand that are old machines and so shims and such things are necessary to bring them proper alive.

Need to maintain standard height so feed rods can run concentric.

@@BrianEltherington but what determined the thickness of the turcite(sorry, I don’t know how to spell it!!

Sounds to me like the straight cut gear noise from running the feed.
