Thanks again, Marc. Super helpful. I was wondering what the hole was for, and now it makes perfect sense. With your help and the other members here, it looks like I'm good to go with my Seitz tool set. I had to order some replacement pushers, but with those, the set is complete and in good condition. Now, I need to figure out what tool to buy to measure jewels (amongst other watch-related parts). I had my eye on the JKA Feintaster micrometers, but people get crazy bidding on them for $400-600 USD. I was thinking of just a regular digital micrometer (Mitutoyo). Thoughts? Mahalo. Frank -
Yep, that's exactly how it should fit. The reamer shank is tapered and the socket in the spindle is also tapered so that the one centers in the other and is gripped tightly. If there is any wobble when the reamer is seated as far it will go then there is a problem. The cross hole in the spindle is to allow you the push the reamer back out again. If the reamer seated much deeper then it would limit the access for pushing it back out again. Here is one of mine for comparison. -

I think it should be the other way round, thanks to you. -
You have been a great help to me on many occasions. Thank you for the offer… -

Another Question. Does this reamer look like it fits the reamer plunger? This one and all the others feel like they should push in all the way. Are they made like that so they don't turn or move when reaming a hole? Thanks. Frank
