Mystery Project...

You will still spend the time just modifying it to fit your lathe. I got the plans for the Grizzly Lathe ( same as my jet) 73 changes later I can use the prints. :lmao::lmao:

It's alive!

... Didn't get much chance to work on it today. Just threaded the locking bolt and bored/threaded what will ultimately be the nut. It's all basically together and functions but there's a lot of little work to do now. I'll cut that long bolt down and will make a built-in tightening lever so I won't need to grab a wrench every time. Anyhow, the heights came-out just fine and centers perfectly...

Ray, are you gonna make a crank and gear to run on your rack gear to move the turrett? Also if i had to err on the height id make it a tad high. Ive read somewhear that new lathes, the tailstock is a couple tenths high to allow for wear.
 
Yes, I'll put a gear in there and drive it off the rack. I was just out there checking things over. Just moments ago, I measured the rack tooth spacing and wrote the numbers down. So far, everything clears. The diameter of the plate and 60[SUP]o[/SUP] spacing was chosen to give clearance with the compound and compound knob. The overhang height of the taper blocks clears the top of the compound too. I'll have to move the light fixture that's on the carriage but, that was a given at the onset.

Also, yes, the height right now is two thou high and that's easily adjusted. I still need to put oil grooves and feather scraping on the slide plate. Right now, it's all small work like the gear, crank handle, a bunch of alignment pins etc... Still a couple days work ahead but this is a side project so I'm not knocking myself out. Also, the day-job has been keeping me busy lately... We'll get there!

One other question, ive never ran a turrett lathe so i have no clue how they are attached to the ways. I would have to assume they would have roller bearings like alot of carriage's have. I would think just a hold down like a regular tailstock would have too much movement. I like this build so please dont mistake my curiosity as anything different.
 
Correct. The clamping plate underneath is pretty beefy and has provision for two rollers (or possibly four). The underside of the ways are well ground. I'd like to come-up with a two-part method of locking the clamping plate. One method locks it firmly and the other method will allow constrained rolling motion. I may need to reach my fingers in there to kick the rollers in/out of place as needed or, I could come-up with something fancier than that. It might be a "work in progress"...

Like i said in the previous post, i have never used a turrett lathe so i didnt have a clue. You make could do something similar to a carriage lock.
 
We can absolutely make this an interactive design project... I have never in my life not accepted help and ideas when they're made available.

I think eveyone knows what we're talking about... It's nothing more than a plate that presses against the bottom rails of the ways -and this locks the tailstock.

The mission: Come-up with a way to make it either slide freely, lock when needed or roll with minimal lift (for the purpose of drilling or driving the TS with the hand crank).

Go for it...
