Need Machinist to Make Step Centers
May 24th, 2017 at 4:29am
 
     

I need a machinist to make step centers for my lathe that will fit different sizes of the flutes I make.I have a Jet 1642 with 1 1/4" by 8tpi on the drive end and I have this adapter for the live center in the tailstock end.

The step centers would be on both the drive and tailstock end and would just need 1 1/8" , 1", 7/8" and 3/4" steps. Should be a simple build. I would like to trade some turning tools or would pay someone to make these or I could make some in some good hardwood ,but would love to have some nice metal ones..Thanks in advance!

Mike, if I may make a suggestion.
I would invest in a spindle tap (or two) so that you can make your own bushings. It may wind up being less expensive than having parts made for you.

Mike,  you can turn 6061 aluminum on a wood lathe, or perhaps better derlin rod. 

Center drilling the outboard ends and use of 60 degree centers on both headstock and tailstock resolves minor misalignments of headstock and tailstock. 

I have a set of 1 1/4 inserts I use for peppermills. 

Want to use wood --  quarter sawn hard maple, mesquite, and hop hornbeam are stable.

If you need a picture, let me know.  The ones I have are pretty direct and not at all complex.

One set for one size.

I like Ken's idea of a delrin rod for durability and ease.

For the headstock a simple drill chuck or "work arbor" 2mt.

For the tailstock (if you have a Nova or Oneway live center) the rod can be tapped. For the Nova use the threaded insert and you may be able to use a tee nut instead of tapping, for the Oneway you will probably need to tap it.

Links are only for illustration and not a suggestion for that particular item.

Mike --  Here are a set of peppermill bushings.  This set was the 1st located and use a stub end that I mount in the ER 32 Collet Chuck on the head stock side.

I use the ER collet because it has run out a bit under 5 thousands and the drill chucks I use on the lathe are the $30 dollar kind with 25 thousands runout. 

Tailstock holds a 60 degree live center that fits the dimple.   

The flange on the headstock side is larger for more friction area.  I have on occasion on long turnings put 3 small pieces of PVA backed sandpaper on it for more torque resistance.

6061 aluminum which turns easy on a wood lathe

I like those.I have made something similar out of some kind of hard oak my son found....hardest wood I have had...I will get me of the 6061 and make some...   Where is the best place to get the 6061?

Mike, with the small sizes you're talking about, there is very little surface area to provide much driving friction.  Delrin might not be the best option, considering one of it's major advantages in other applications, is that it is slippery/low friction.  Wood would Smiley  likely give you the best driving friction.

Mike,

A few years ago I wanted to do something similar so ended up going with a setup that supports a standard 3/4"-10 thread.  I'm sure you could find everything you need for your 1"-8 thread.  My setup was quite an upfront expense but SO worth it in the long run.  Like others I use hardwood and Delrin for my custom fixtures.  I also agree that going this route would be a lot cheaper than custom parts from a machine shop (no offense to anyone in the machining business).  I hope this helps.

On Line Metals is one source for online metals.   There are others.

You can add a metal lathe to your support tools now also.......

Last --  rubber chucky sells a variety of cones that can be used for similar purposes.

The ones Ive made from wood so far have worked good.
