My brother-in-law wants me to make him a custom wood shaper cutter for making a special molding. His shaper is made by grizzly and looks like a router on steroids. I know the usual ones are made of steel with carbide inserts brazed on. I can not find carbide that is big enough. It needs to be about 1 1/2 x 2 1/2 . I have some power hacksaw blades that are big enough to use to make the blades. The blades are only hard on the cutting edge but I did try to harden them and the whole thing will get hard enough that you can't file it. I know I can't harden these and then braze them on because they will loose their temper. So I am thinking of using small countersunk screws to hold them on the cutter. This cutter is going to be about 6 1/2 in diameter with three blades. I am kind of worried about the blades flying off. The slowest the shaper will go is about 10,000 rpm. I also don't know if they grind the profile on the blades before or after they braze them on. Any help would be appreciated. Jim P.

Don't know exactly what profile you are talkign about so I can't say for certain, but there may be an easier way around this. They do make (I've seen them, but don't know what manufacturer) tall narrow bits that you runyour stock through on edge instead of flat on the table. Instead of a windmill you run a thing shaped like a tall skinny christmass tree. Poke around, there may be a reason why they don't make them like you are trying to do. Dave

Basically, unhardened high speed steel. Cut the blades to the shape you need, then harden (heat and quench). For cutting wood, you don't really need carbide. Al Moore

A 10g cutter will want to fly off with 100Kg force. And that's before it actually hits wood. I can see no possible reason for running at this speed, unless you need very aggressive feeds (coming up on a meter a second)
