SUCCESS!! - wish I could claim it was all my own doing but it wasn't. First here's the back story - anyone following this thread knows I have been struggling with the whole power transmission side of this machine. I was getting desperate and felt something bad building up so before I did something really stupid I decided to stop and let it rest awhile. In the meantime I went looking for a parts schematic/manual for this saw - posted a BOYD ad here and on four other forums. I also posted a CL WTB ad on 6 different larger cities in upstate NY. Not much luck finding the dirty paper (I haven't given up on that yet cause I would like to have it for reassembly) but I did get some CL responses - most pointed me to OWWM
, one told me to get rid of the piece of junk and get a cut off saw, one identifed another forum that may be of some help. The final response I got was from a fellow who recommended a machine rebuilder about 50 miles south of me. I gave them a call and, of course, they had never heard of L.W. Chuck Company and didn't have any paper in their extensive files but they did agree to take a look and maybe give me some guidance. I drove it down to them this morning and the shop foreman took a look. We discussed all of the things I had discovered and thought I knew. He said I did all of the right things and that he too couldn't see an obvious disassembly path. He was starting to conclude that one end or the other was pressed on. I suggested that didn't seem to make sense to me from an original assembly perspective and he agreed. So he said we charge $85 an hour and would I be willing to leave it for one hour - if they couldn't get it in an hour then they probably couldn't get it at all. So the deal was one hour ($85 is almost as much as I have in the whole machine) - if they couldn't get it apart then no charge, if they got it apart then the hourly rate and if they broke something in the process they would repair at no charge. So off I went to get a cup of coffee and relax.
I returned an hour later and didn't see anything laying around - The foreman said follow me. He showed me what they had done which was basicallly trying to remove the "eccentric ring" - which he felt wasn't an eccentric at all. He gave me an option of chiseling off the ring (which he thought may be pressed on) - I told him that seemed like a potential solution but that there had to be another method as that didn't sound like the way this would have gone together. He agreed that either end being pressed on as the final assembly step didn't make sense. So we both stared at it awhile and then he started taking a closer look at the crank wheel end - finally he said - that looks like it may be threaded and the light bulb went on. That made perfect sense in terms of the original assembly process. We discussed that awhile and finally decided if it was threaded they would right hand so as to be self tightening in operation. He took the whole assembly to a 16" lathe and chucked up the sector gear end of the drive shaft to keep it from spinning. Then he smacked the crank wheel with a piece of brass a few times and BINGO - off it came. With that off the rest of the pieces pretty much took themselves apart.
Here's what I started with
Crank wheel and Cam off - the cam is pinned to the crank wheel and goes over a shoulder on the drive shaft
Then simply pull the drive shaft off - the "eccentric" collar is, I believe, pressed on but I'm going to leave as is. There's no good reason to remove it. I no longer believe this is an eccentric but simply a shoulderthat locks the gear on the drive shaft
Then I pulled out the sector gear and bushing (after removing the taper pin). It appears the gear may be pressed on the bushing but I'm going to leave that as is too - I can mask that off for cleaning and painting. The right side of the gear is counterbored to accept the locking collar.There is a groove in the outside of the bushing that the taper pin goes through to lock the gear and arm together.
Finally the arm simply comes out from between the two cast uprights
This was quite an adventure and learning experience so well worth the cost - oh yeah - they only charged me $40. Not much left to do in terms of disassembly except remove the vice and clean up the base cabinet.
Thanks to all who have been participating in this piece of the rebuild. I'll be back if I run into any other problems. I still plan on doing a pictorial of the reassembly so the next guy who stumbles onto one of these machines will have some information.
