It's kind of like a cross between a split case and a clamshell. I bet engine swaps would be a snap.
I found a new one on Feebay at a pretty good price, now I just need to get off my butt and send to Mastermind, so he can work his magic.
Are you talking about replaceable bar tips? The chart I found is for complete bars.
If you are talking tips maybe the gage is different? Width of bar? Mounting pattern?
I don't know, I just happend to find the breakdown of the numbering system while trying to see what a bar listed on...
The UA would be initials of the brandname, which makes no sense to me as it is Sugi Hara branded.
I think the 10 is the mount type. The Sugi Hara bars look to me like they combine mount paterns so the same bar can be used on several saws.
Don't make any bids you're not willing to pay.
I plan on bidding on it when it's listed, probably will get outbid, but if not then I'll have a new-to-me 394.
