Working on my South Bend 9C

[Golem Pens]

I need to reassemble the spindle assembly fully before anything definitive but this seems very close.

I've got stuff to make a nicer handle on the end too, but that would get in the way of the gear cover in hindsight.

What kind of runout are you seeing?

You put the draw bar through the gear cover when they have handwheels on them..... 😉

.... I'm pretty not smart 😉

Probably get you further than lifting heavy things has gotten me. 😛

I need to reassemble it properly (after kids are in bed) before I expect a real reading...

I hope this works.

Then at least you can use the machine for some pen action.

You can buy 3 and 4 jaw chucks on mt3 arbors as well, which might just get you by or at least let you fabricate something to fix it.

Maybe the MT3 route takes you long enough that you just sell the lathe in a year after using it a bunch and upgrade….

A 12" length of all-thread is ... $3.38 at the Home Despot at the end of the block, I'll take the lazy route for now!

I get it. But I'd still make my own because I can make it better that what the bulk stuff is like. At a minimum, make yourself a centering collar for the back end so the rod stays centered in the spindle. The Morse taper will automatically center it at the front end.

I believe this is my high point. Is that .001" (one thou) TIR?

Yeah as soon as I put it together I realized I wanted something to center it.

Yup. That's pretty alright all things considered.

Looks pretty promising. Mark how it's orientated in the spindle with a felt marker, and maybe you could play around rotating it, choose the best location and mark it with something more permanent

Hard to complain about .001"

@Golem Pens I would say you are in business sir.

Tomorrow I'll get the bench cleaned up and take some test cuts and drills. Fingers crossed! I'll probably make those delrin drill depth stop collars as a nice little functional project.

I don't mind buying one to prevent damage. Especially if someone points me to a suitable/good enough unit.

Hi Michael, Guys,

Pity you're not this side of the pond.

My good Mt2 & Mt3 reamers are Dormer ones. As are my MT1 and MT5 ones.
I did have an MT3 Chinese one but that got borrowed and never came back !

 

[Golem Pens]

Thankfully the marring is below the level of the taper and doesn't seem to contact the shank!

I don't know what size you need. I have reamers for 0,1,2,3,&4. Happy to loan you the one you need. But I'm guessing the shipping would make buying one more economical at $36.

I'm not convinced that reaming the taper is necessary.

It seldom is. He also says that the deleterious is below the taper. But the option is there.

 

[Golem Pens]

I appreciate the offer! Unless problems seem to crop up I'll probably leave it be for the time being. Couple more hours of work and then I can check out how it's running 😉
