Re: ER32 Collet Holder (old "source for replacement chuck jaws")

I think counting on 4 set screws to hold the plate from moving is folly. I think you would need some screws from the front or back to hold it in position once adjusted.
That said, just make one on your lathe. This way you know it’s concentric, as you cut the taper after it is mounted on the spindle.  I am a rank amateur, and I didn’t find it too difficult. Take your time, check your setups before you start cutting. It is very rewarding making your own tools!

Re: ER32 Collet Holder (old "source for replacement chuck jaws")

I purchased a commercially available ER32 Collet holder for my SB9 which is about 4 inches in diameter.  I also purchased an eight inch threaded back plate.  My idea was to inset the collet holder into the back plate with four set screws coming in from the outer ring of the back plate to allow me to adjust the collet holder slightly and remove or reduce TIR.  What do you think about that?  Am I nuts or just hopeful?

Yes, I did. I used it because it was fast and easy way to get a ER-40 system. Also, what the large chunk of steel would have cost me at the time, getting these premade units were cost effective.

One other reason I had was I wasn’t confident enough to cut the taper accurately. At the time, I was hadn’t used machine tools since school shop class.

Al, why did you use a threaded backing plate instead of just making it as one piece? Is there an advantage that I’m not thinking of?

Re: Anybody close?

Ondrej Krejci
 

Greetings,

Actually, my 1917 Monarch required new headstock bearings, a countershaft with cone pulley, rescraping of all the ways, shimming of the tailstock...basically a complete rebuild.  After five years of putzing with it, I had a lathe just as bad as when it was new.  The only reasons I bought it were the price, 250 USD, I had a spare motor, it had a quick change feed/threading box, and I´ve rebuilt enough machinery for other people.
I really doubt that the average hobbyist would go to such lengths restoring the SB lathe from the ad.  It looked worked to death running parts in the collet.  The Atlas seemed to have a small drill press bolted to its bed...single purpose/job machine that worked its way into the dustbin?
But, I´m sure either would perform well in blacksmithing or woodworking as is.

Cheerio,


OK

I don't want to start a flame war but your boat anchors could be somebody elses project or parts lathe. What condition was your equipment acquired in? I'm guessing because you look at these lathes and sneer they must have been new old stock. I've rescued many a old machine from boat anchor status and learned a lot along the way and had fun while doing it. Just because you have no interest don't disparage others who may.

Thanks Steve.

I used scrap steel that I had, it cut like 1045, but not sure.

I did not heat harden them.  I haven’t noticed any wear in the tapered bore, but I’m just using them in a home shop.
