« Part 8: More Parts Received Part 9 of Unisaw Rehab series Part 10: Reporting for Duty! »

I got back on the Unisaw rehab today. It was pretty hot in the shop, so I had to keep a towel handy to keep sweat off the cast iron. Weather guy tells me that the high temperature today was around 94F with humidity in the 80% area. Not a real surprise for south Louisiana in September though.

I realized that I had not painted the edges of the cast iron top, so I removed them (with my wife’s help) and set the assembled top on my workbench. I flipped it over and removed the wings. I put some effort into getting a better shine on the top. I used the RO sander with 220 grit and dry sanded the top and wings, after which I wet sanded by hand with 800 and 2000 grit. I used mineral spirits as the lubricant. While the shine is much better than when I started, I am still not very satisfied with the level of polish. I accept that this is as good as it gets, though.

Top with edges painted, reinstalled and realigned.

Wings all shined up, edges painted and ready for reinstallation. I had planned on doing that today, but the high humidity extended the time between coats and final drying. I’ll finish that up tomorrow.

In an earlier blog entry, I posted a picture of the top showing an uneven area on the operator’s side of the blade opening. Upon closer inspection, the top is actually cracked. Plan of action: do nothing at this time.

I also replaced the switch. It’s a 1HP, 110V motor, so I just used a standard light switch (replaced what was there before). I tested it, and it does work as intended.

Thanks for watching! I appreciate the comments and critiques.

Looking good! Might I suggest JB Weld for your consideration in filling that crack—just a thought, but I used it to fill a crack on a plane and it’s still holding quite nicely some 15+years later.

@Hillbilly—Thanks for the compliment and for the suggestion. Is JB Weld considered structural, or is it just cosmetic? I haven’t worked with JB Weld before, but I do know that it’s used a lot in auto repair.

Don, I believe it would be structural since it bonds just about anything. It’s an epoxy, two part mix. I used it years ago to repair the impeller on a sump pump in my well house (bond impeller to motor shaft); and, it worked for years (at least 10) until the motor finally shot craps. I always keep some in my shop as it is truly great stuff!

Thanks again, Hillbilly. I might have to give that a try. I hope it’s not too messy—I wouldn’t want to mess up that top!

Its looking sweet Don! Sucks about the crack but doesn’t seem to affect the function. I have experience with JB weld but sounds like it will work.

can you drill a small hole at the end of the crack to stop it? That would be great if you could. Then JB Weld it.

@BeginningWW—Thank you, sir! It’s been fun.

@Grandpa—I used the saw over the weekend and the crack does not affect the function of the saw or table. Drilling a hole to limit the growth of the crack sounds like a smart suggestion.
