Last year I purchased a Forrest 1/4-3/8 finger joint blade combo to use on my Saw Stop and Incra IBox. Just finally getting around to putting it all together and for some reason I can’t separate the two blades. Got the wax off but since I’m new to all this with the double blade I must be doing something wrong??

Are the blades only stuck together, or stuck on a center post in their package? My dado sets sometimes get hung up on the post in their storage container. Once I worked them loose, I shaved down the diameter of the post a bit to make installation easier.

Good luck

Just the blades stuck together. And I mean they are really stuck.

Assuming nothing is wrong with them, they might just be stuck together with a vacuum effect like two plates of glass. Wax between the blades could have the same effect. Try compressed air, then some light oil to separate them. Don’t pry them apart.

You say that you purchased the blades last year. That could be anywhere from less than two weeks ago to over a year ago. If it has been a fairly long while, I wonder if some material used to protect the new blades has become very sticky. You could try giving Forrest a call.

Maybe heat from a blowdryer? Nothing too hot, but enough to make what ever is binding them less viscous.

Yeah. I spoke w/Forrest blades and they suggested WD 40 and stay away from heat. Only problem is these two blades are really fused together and I’m not seeing anywhere to get the WD 40 to penetrate. I took my cheater glasses and a bright light to see if there was any type of opening and none. I’ll try it and see what happens.

I think I would try a couple pine wedges (maybe cut from a 2×4). Split it to make two small wedges.
There is no way they will bend the blades. I have the same set, they were stuck together but maybe not quite as bad as yours.
Tap them in from opposite directions, might just be suction and it may pop apart.

I’d tap a couple of finish nails in from each side. You shouldn’t hurt those blades at all as they are harder than the finish nails.
