This is definitely a mind boggler
My 19” I swear is a LO, and your 15” has a L1, wow!!
I just looked at a 19” on eBay and the picture of the nut to the 22J collet Chuck looks like it could very well be a L2
Mine has a small through hole, maybe 1-1/2” max
It was built in 56, so I recall
I have the original bill of lading, I’ll take a look
These LO chucks and plates are hard to buy, I have a rack full of the bigger L series chucks, so if I scrap this machine and by another one, I should be able to have chucks for it
I really hate to do that since I have all the tooling above my lathe already
I would have to start all over
I have heard back from Gbent, after he said he had acquired the parts from you
I would think that the LO spindle and bearings would be the bearings I need to save this machine
Another question I have for you Mike, is your 15” machine spindle measure 31” in length?
That’s the length mine is
It’s sounding like these were all over the place depending on when they were built and what size spindle bore each machine came with
The 13” servo I have sitting in the shop, that was supposed to have been a 15” has a LOO spindle in it
I’m starting to wonder if Honda has anything to do with this? Just a joke,,,
They changed their parts every year so no one could swap parts
