Thank you so much Harry
You cannot imagine how happy I am that the method is working for you (and not you, working for the method).
First time that I tested the method, I made a few small boxes for my wife to be used for making "Tofu", After I finished doweling and all the boxes sides fit like a glove, I was happy like a kid with a new toy and since then, to dowel a carcass is the most easy and enjoyable part of the project.
Most of the methods that I use are the result of being an amateur and all the "Kuntz" (German for Trick) is, not to spend $200 for a "Dowelmax" or alike (for less you can buy M12V and dedicate it for doweling and jointing) and yes, I like it to be simple, accurate and as you said "Virtually no marking".
But...even not one picture???

Well, show as when you'll finish
Thanks again, you made my day......now, lets make some method to cut frame members at 45° also simple(nik) and take out all the fine tuning...the next post...
Best Regards
