Re: 80mm TAL to 44mm Synta dovetail adapter?

Here's the solution I am currently considering. The attached drawing renders the TAL dovetail with transparency. I will reuse two threaded M6 holes on the steel TAL dovetail, and will add 2 extra M6 threaded holes at 31.25mm (this is 1/5th of the distance between the centers of both holes I will reuse). On the Vixen dovetail (that came with my Orion Sirius EQ-G mount) I will have to drill 4 holes for M6 bolts as well as one hole for accepting the 2nd alignment pin of the TAL dovetail:

Tal-200K (#199) with JMI NGF-Mini2M focuser on GEM3 • Astro-Tech AT80ED on Orion Sirius EQ-G with EQDIR & home made wireless EQDIRECT • Celestron Regal LX 8x42 & 10x42 • Helios 15x70
ATM 14" f/5 (designing mirror cell and filter wheel/focuser) • ATM 10" f/6 Portable Truss (polishing) • ATM 10" f/25 Dall-Kirkham (primary: polishing, secondary: #120 grit)
