Well I have been busy the last few days. I finally got the top arm out, I had to drill out the hardened socket head bolt that went through the bottom bearing as the nut threads were stripped. There is an access hole for a hex key but that took about 45 minuets to get out,that's hard steel. The bearings (6202-z) seem fine and are readily available under $5 each but the bushings on the other hand aren't available. Checked with local machine shops and they are too busy to take on a small job. Got hold of an online shop that quoted me $250 each (2 maybe 4 if lower ones are the same) that's $500 -$1000 +tax and shipping. I reassembled the saw minus the upper arm and found no slop or excess vibration even on top speed. So hopefully at least the bottom end is OK. The bushing stub that engages the barring is 8thou under size. Touched base with my local machine sales Co to see if they had any good used lathes in. They said a 2 year old King Mini Lath is coming in this week which I can have for $500. Looks like my only option, if indeed it is in good condition. I'm sure I will find a use for it after the saw is back up and cutting.

pin-less is all I have ever used

They were taken with an IPhone and the clips were converted to MP4 on my PC Windows 10 and then attached dragging to this window. The only thing that shows up is the progress bar and the sound. It should be straight forward but isn't working. I spent a lot of time this weekend looking for the original manual, I finally found it safely tucked away. The saw is circa March 1988. I also employed an endoscope and it looks like a reasonable disassembly. More accurate evaluation later. I will try and document the process as I go and will post accordingly. The big question that remains is finding parts. I will also make a PDF of the manual in case someone else needs it.

I can't seem to get the video clips to show. They are MP4

Thanks for the manual. the biggest problem I see for repair is the main body is all one casting with a 2" X 2" hole at the back and about a 6" round area on the left hand side opposite the pulley shaft on the right. I don't know what happened with the clips they were taken with my phone and converted to MP4. I will retry that and some photos of the unit tomorrow. Thanks again

I have tried twice to upload 2 short clips of the problem, first time it was the wrong format so I converted it to MP4 and uploaded it bur only sound and a progress bar showed up on my end. I will take some photos of the saw tomorrow.

It was made by Sommerville Design & MFG Inc In Canada, British Columbia I think

I was very pleased to discover your website. Anything I read leads me to see a lot of knowledge and experience distilled into one site. Thank You My Excalibur EX-24 is roughly 40 years old but has remained mostly idle for the last 28 years because of a motor vehicle accident. I live in Ontario Canada and have recently been trying to relearn as much as I can Re woodworking in general. About 3 weeks ago I decided to tackle a set of piggy banks for the grand kids. It started out fine and I managed the internal cut on 4 pieces until I heard a loud snap that sounded like a mouse trap only louder. No mouse was harmed but the Excalibur was jumping and shaking, not smooth as normal. My initial examination makes me think the rocker bearing needs replacing. I managed to find a PDF copy of the manual but from that I can't see a way of disassembling the saw to allow the replacement. Also the bearing number doesn't seem to be an industry format. I have attached a photo of the information sticker as well as 2 short clips of what I see so far. Thanking you in advanced for any incite and or guidance you can offer.
