Hi. i have a unisaw model 36-815 from 97. I tilted the blade all the way to the right, and now can’t get to go back.
Anyone else have this problem, and what do you do to fix it.
Thanks for any help you can give me. Joel

Turn the handle the other way.

I’m not sure about the unisaw. I know that the standard way the locking knob works on most saws is that a rod screws in and forces two woodruff keys outward into a stationary tube, immobilizing the tilt wheel. I had my old (1957) craftsman get stuck. Try removing the locking knob. There should be a rod behind it. You may have to use a magnet to remove the rod. From there you can tap on the tube the rod goes into and try to work the tilt wheel back and forth slightly. If this frees it up, pull the whole mechanism apart. It sounds scary, but you can do it. Clean the keys and tube, lightly oil and reassemble. I hope this helps.

There is a center knob that will lock the larger wheel so the saw will not vibrate out of alignment after it is
set, check to see if this has been tightened. If it is loose, you can take the four bolts loose that hold the
saw top to the cabinet, lift the top off and have easy access to the mechanism. It might take a little work,
but this saw is worth it. If you do not have an owners manual that tells you how to service and repair this
saw, you should get one. They are available on the internet.

You broke it! Now you have to tilt the entire workshop 45 degrees to even it out.

If you choose to remove the top, keep track of what appears to be washers in each corner, they are actually shims, and you need to put them back exactly the way you find them.

Thanks to all of you, for your advice.
I did turn it the other way. didn’t help.

My wife said I can’t tip the garage 45 degs.

So I guess that leaves Dave’s idea, I took out the knob and it look just like you said. I am waiting for my son in law to come over and provide the muscle {if i need it} to get the pieces out. I’ll let you know how it gose.

I forgot to mention. The woodruff keys are probably brass. Mine had little burrs on them, which is why I figure they got stuck. If this is the case with yours, just file or sand the burrs off the corners in addition to the cleaning and light oiling.

If you’re spinning the handle fast to either the 45 or 0 degree stop and hit it very hard it can jam the trunion in such a way that it seems locked into place. I’ve found that a sharp blow with the palm of my hand usually breaks it free (make sure your going the right way!). The same thing can happen to the blade height adjustment, especially if the blade is adjusted down fast and hits the lower stop hard it locks everything up pretty tight. This should be avoided as the gear teeth cut into the trunion and blade support are cast iron and the weak link, ironically the most expensive parts in the system to replace as well.

Hi. We (my son inlaw,and me) ended up taking the whole saw apart. There was nothing broken or bent, so we cleaned it up lubed up with silicon and put it back together. We still have to square up the top with the blade, and put the side table and the fence system back on. All in all not to bad, it needed a good cleaning anyway.

I think the problem was just what the one person said I went to far and jammed it.

Thanks for all the suggestions.
