mortise bits

[BigCasino]

does anyone use mortising bits? or regular drill bits? I have been using a standard bit for my mortise but I am curious to any advantage to one or the other

I drill with regular bits but slightly undersize. I then ream to final size with a chucking reamer. I cut the tip of the tip of the tenon to match the profile of the tip of the reamer.

One of the main reasons I like to drill and ream is that I use a lot of .312 dia. Delrin tenons. The Delrin rod stock is extruded and runs pretty true to size. I occasionally do find variations within a given piece. It can run plus or minus two or three thousandths anywhere in the rod. I make the the tenon first then mike the diameter. Chucking reamers come in decimal sizes, .001 increments. There are also dowel pin reamers that have half thou. increments. Thus it becomes straight forward to tweak the mortise hole to get a good fit with the tenon. I've also started installing the tenon into the stem using threads. Either 5/16-18 or M8 X 1.25. Any lingering worries about a glue joint not holding are gone.

We can either settle this like gentlemen (I'll get my dueling pistol down off the wall and start getting it oiled up) or you can have your solicitor contact my prestigious law firm of Dewey, Cheatem and Howe located in Slapout, Oklahoma. I relish the court battle actually. That Myford Super 7 will soon be all mine. My ruthless attorneys will even make you personally deliver it to my door. You have no idea of who you are messing with.
