I’m having a problem setting the blade 90° to the table. Using a Wixey digital level, I can’t adjust the blade any more than 89.4°. I tried adjusting the 90° stop; it didn’t improve. I removed the stop screw and ground some material off the head, put it back and still it didn’t improve. I’m thinking there may be a buildup of sawdust on the rack for the tilting mechanism that is preventing the worm gear from adjusting fully. I cannot see the rack or even touch it without turning the saw upside down. That would be a very big problem for me, as I would have to disassemble the Biesemeyer fence and auxiliary tables and turn the saw over. (I’m 78) The saw is about 30 years old and always registered 90° until recently. Anybody else had a problem like this? This is a serious problem that I can’t live with. Blades MUST a be perfect 90°.

I’m not familiar with your saw, but can’t you see what you need to see by removing side or back covers off the cabinet?

No. The cabinet wraps around completely. There is an access door near the bottom for sawdust removal, but too low to see anything. BTW, the saw is a model JTAS-10 made in Taiwan.

have you checked the wixey with a drafting square or trisquare? i looked at the schematic in the OM and it looks like a unisaw clone in it’s trunion and motor bracket arrangement. is there any chance a wood chip is lodged in the helix on the tilt shaft or in the teeth of the front trunion? and what can you see when you open the motor door, which provides access to the interior of the saw cabinet? is this not your saw:

With my JET , I am able to remove the ZCI and then the blade and then see pretty much what I need to see from the top. I routinely blow out my saw with compressed air , paying attention to those critical areas such as the stops : )

-- I'm absolutely positive that I couldn't be more uncertain!

mrron …..... any chance the dust deflector that attaches to the front trunion and partially surrounds the blade has become misaligned? when i tried to fabricate and install a similar deflector on a unisaw, it prevented the saw from bevelling to 45*. just trying to think of things to check.

Toolie: That Jet is very different from mine. Mine is a right tilt and the cover for the motor is much smaller; not big enought to see what I need to see. The new Jets have accessible adjustment screws for tilt. Mine doesn’t have that access. I guess I’ll just have to enlist a couple of strong friends to move it around.

Have your say...
