I just got a used Craftsman table saw and although I'll eventually upgrade I've got to deal with using this one for now.  You don't find too many cheap used saws that work well and have a riving knife built in.  This one doesn't have a specific riving knife, but it has a blade guard that's supported by what effectively serves as a riving knife.  Problem is the blade isn't lining up with the 'knife' even though all parts seem to fit together as they should.  Are there spacers out there that are designed to adjust a blade left and right on the arbor?  Also, my new blade, a 7" Diablo combo is .04 thick while the saw's knife is .08.  So in addition to adding a spacer on the arbor it looks like I need to get a thicker blade.  Any suggestion there?

 

Question (subject) number two...caulk adhesives that will stick to plastic.  I use liquid nails heavy duty for a lot of my slap together projects but it doesn't seem to stick to regular 4 mil sheet plastic that well.  Can anyone suggest a caulk tube adhesive that sticks to both sheet plastic and wood well?

Providing a model number might allow us to look at a drawing of your saw's internals and suggest something, but I don't think I'd try to move the blade to adjust it. More practical (maybe) to adjust the splitter. As for the blade thickness, are you trying to use a circ saw blade (7") on your saw. I'd think you would want to get a 10" or so blade...the thin kerf ones are generally .091" thick and should work well with your splitter.

Try Liquid nails Fuze it if its not polyethylene or polystyrene.

Agree with Fred about moving the splitter rather than adjusting the blade. Just depends on how the saw is constructed.

I have a Craftsman 137.218250 ...

 

 

It's cheap but it's what I've got to use for now.  Hopefully will be upgraded soon.

 

The Liquid Nails Fuze It has been suggested in other places as well as the PL line.  I'll probably go with one of these two with some mechanical 'adhesion' added for good measure.

 

 

I looked at the manual diagram https://www.manualsdir.com/manuals/632656/craftsman-137218250.html?page=8 and it looks like the splitter/guard mounting bracket can be adjusted. https://www.manualsdir.com/manuals/632656/craftsman-137218250.html?page=12. The mounting bracket has an elongated hole.

 

I'd also check for a slightly bent splitter, just in case.
