Part A-2291 on the 10ER is the quill bumper ring.

Thanks Rob! I am still unsure of where the 'second' one was. As I recall(not too reliable) it was inside the headstock somewhere along the quill splined shaft, main bearings. It was covered with the same grease as the splines. I did not see where it came from. I was 'found' in the headstock after removing the quill and rear bearings and drive shaft.

P.S. Also known as 102-53! This part NOT in 10E manual! It is one of the 'improvements of the "R".

New 'problem'!

One of the foot pedals has the roll pin in a blind hole. Any one seen this before? I am considering drilling through the roll pin and out through the opposite side, then enlarging so as to be able to drive it out.

Any alternate suggestions?

EZ out will possibly grab it?????? Is it a roll pin (multiple coil) or a spring pin (single coil)?

I'm with you on the drilling technique.

I would almost be tempted to come at it from the other side with a smaller bit to find the end of the roll pin, then slowly increase drill size. I would think that the end of the pin is not very far below the surface. You could guestimate how far with one of the other roll pins.

You may not be very successful in drilling out a roll pin. Roll pins are made from spring steel and are VERY hard. They often are harder than drill bits and so the drill goes dull long before you make any progress. Frozen roll pins are a big problem even for machinists. Do a lot soaking (PB Blaster) and use the correct size drift. That maybe the only possibility. Speaking from a lot of experience drilling is a road to exasperation.

If I followed him right, I think he was going to use a small drill bit that would fit down inside the roll pin and drill a hole in the foot pedal. Then, enlarge the hole with a larger drill bit from the outside. Then the roll pin could be pushed out.

Was I interpreting that right, jpg?

Yep! You listen real good! Not sure if it is a roll pin or a torsion pin.(that was for mike's benefit!:D)

Roll pin on the left, spring pin on the right. Most likely, you have a spring pin. (torsion springs be different...like in mousetraps, garage door opener assists, ER10 trunnion stop lever spring......I know you know that....must be a case of 'sometheimer's' disease ).
