Review on General Tools 841038 8 Inch Accessory by Loren Jacobson

I used these dowels to attach a mortise and tenon joint for a 4" x 6" Douglas fir pole to a 1 3/4" mahogany base I like to use when drilling dowels to sharpen the bit so the bit doesn't dangle inside the locking ring, not outside.I have General Tools dowel sets for 1/4" and 5/16" and haven't had this problem Other than that I had no other problems have the same size and a sharp drill bit.
