Ok, for anybody who has been following this thread and is interested, I just went through the entire parts list along with numbers and sizes etc. between the Excalibur owner's manual and the Jet owner's manual. The list of parts is exactly the same for the basic saws. If Jet changed anything on theirs, I didn't find it. Anyway, the bearings and sleeves appear to be exactly the same for both saws. I found a supplier online for the bearings and I think it is the same supplier that I have had some correspondence with. They are VXB in Los Angeles. Right now, unless my figures are wrong, a person can purchase all the bearings necessary to rebuild their Excalibur saws for $62.67 plus tax and shipping. As for the sleeves, I will have to contact Jet to see what they are going to charge for those parts. I would be surprised if they are going to charge more than Dewalt and probably will charge less. Who knows? I'll try to contact them tomorrow and see. I'll be back, so the saying goes.
