Thanks Oldtool! I'm glad you like it and thank you for the kind words. 

To answer your question.....
Oldtool
......how did you ensure you drilled the registration holes so perfectly?

Well... the short of it is...I made an "little indexing jig" for making the "letter stamping indexing jig". Sounds crazy I know.

Here's the details.....

I made it on the drill press. You'll need a very straight fence. You'll be advancing your piece so the fence surface needs to be very straight. Here in FIG 1, I am checking my fence. You can clamp down a piece of 2 x 4 for a fence if need be.

FIG 1

The holes you drill and the locking knob shaft have to be exactly the same diameter. I used a 7/32 lipped brad point bit but a twist bit will work fine as well. I made a 7/32 dia dowel to match my bit per FIG 2.

FIG 2


I took a scrap piece of plywood and pushed it against my fence, pencil marked where I wanted the first hole to be, drilled, and moved over 1/4" and drilled another hole. See FIG 3 & 4

FIG 4
Next I glued in a short piece of the 5/32 dowel for the indexing pin.Then I cut it off into a "little indexing jig"

FIG 5


Then you drill your first hole in what will become your "letter stamping indexing jig".
Then you place the "little indexing jig" dowel pin into the hole you. Drill again.

FIG 6


Then it's just step and repeat.

FIG 7

Hope I explained this okay. If you have any questions, please ask. 

Cheers!
