ERLover wrote:Welcome Mike and to the dysfunction here. I have 3 ERS all with the SC. I like them with the SC because on the low belt setting you can take it down to 425 RPM, up to 1100ish RPM and anywhere in between, One is a dedicated drill press and an other a lathe. Without the SC on the low setting you at 700ish RPM. On EBay a rebuild SC runs right around $175. You may find them there cheaper but might need some work but they are a real simple thing to rebuild, not much to them.

Geez Bob, you just keep on keeping on(off?).

Lo ~= 825 (1/2 Motor rpm)

1600 ish!

OK, I am confused. Low speed without the speed changer is 1750/2=875 High with the SC is 1600ish. A typo I suspect.

"LOW 5 SPEED" = 1600 RPM.

Ya multiple conditions, too simple answers. Need to relate them to ER's previous post.

If I had one like that I would put it in my family room next to my custom saddle and not use it for anything other than art.

It does not take much work go to restorations.

John I am guessing missing info/interpretations here, on the low setting pulley set up it is around 1600RPM max WITH a SC. If with a SC flip the belts we know it is much higher RPMs, cant remember the low-high on that setting since I run the low side pulley, I have no need for the high side.

Just like I say, the 3 hair splitters here, I wont mention names
Corecto my man, from Pulp Fiction, yes correct is needed so we dont confuse/misinform the Nubies.

I was commenting on JPG's calculation for the low speed with out the speed changer. The high speed with the SC in the low setting is 1600 and that is what I said.

I figured that, just wanted to get us on the same page since that # is not in MY HEAD. I know it is around there though, I thought a bit lower, but WTFDIK, I run em on the low end, I wish I could go lower then 425rpms sometimes, but not going to pop for Skips DC drive just yet.

You can always get a smaller motor pulley. A 1" should get you down to about 200 RPM's. I don't know if a pulley that small is available for a 5/8" motor shaft. The problem with changing the head stock pulley is that the bore is non standard. However a machinist could make one.

John, what is the small one on the 3 step, 1.5"? Maybe a thing to McMaster and Carr

What about belt size or just adjust the motor height?
