Brake shoe bonding adhesive
I've got to put a new brake on my old Clausing lathe. I've got the brake shoe material from my local auto parts store, but now need the bonding adhesive.
I've looked and looked on the net for something readily available and can't find anything (unless it's made in India). I've looked at both 3M and Devcon sites and didn't really see anything specific to my application. I don't want to buy a large quantity of something that I'll probably never use again.
Does anyone know of something better than just a 2 part epoxy or the real handyman's secert, J-B Weld?

I used Pliobond here JR, on this "green" lining from McMaster-Carr. It did not let loose the single time I used this tool. Its very "fumey" (full of MEK) so it won't last very long sitting on the shelf.
Have quite a lot left that I would be happy to send you if you want to try it.

I have bonded friction material to a brake setup on a small resaw using a Loctite brand gray epoxy. It has never pulled the brake material off the backing and it's stopping a huge rotating mass.
I would bet the adhesive section at your local hardware store would have a high strength two part epoxy that would be just fine...maybe even JB Weld as you mentioned.

Something "Thermo setting" would be ideal. Epoxy softens at elevated tempertures. Application will determine how hot your bond may get.
Rivets are fool proof at all reasonable tempertures!

That's what I like about this board. Good fast answers.
Which Pliobond did you use on that, the 20, 30, or 30HT. How much do you have left over? Would you take a check for shipping and payment for the remainder?
The local hardware store sells Pliobond and some generic epoxies.
The auto parts store can rivet, but Clausing was kind enough to make the brake shoe a solid block of steel.

I used Devcon 2 part epoxy rated at 200 degrees to make a prony brake which gets very hot, but the heat does not transfer through the lining to the glue joint. So far so good Bob
