Older Craftsman radial saw
The model 113.29411 radial arm saw that I've owned forever is finally giving me a problem I can't seem to fix. Hurricane storm surge is ultimately to blame along with my failure to completely dismantle it earlier. Although no part of the saw got dunked, salty atmosphere and fumes from a bunch of melting fertilizer got to it. It was working just fine following the storm but after some time with limited usage, the elevator locked up on me.
I've taken it apart, cleaned, lubed, and polished everything (including tube, column, key, keyway and elevtor crankshaft with emery cloth) and replaced a bad elevation shaft/gear. Everything is slick and smooth as can be but the elevator still won't raise/lower the arm. It's as if the gears aren't meshing together tightly enough. The crankshaft gear has no visible wear.
Anyone have an idea on this thing? Perhaps there's a certain crucial alignment combination of tube with the column that I've not cracked yet?
