that sounds about bang on.
This buckle is the only piece that is a problem because it is about 1-1.5" deep. And like you said, i am making a cavity that sil is poured in. There are no details in the bottom of the cavity, but never the less- it is a deep cavity.
I afraid i just dont have the knowledge or training to do what you propose
But it sounds awesome!
I think for the time being, i am going to try a long reach bit again- and then just take it way easy.
unfortunately- this project has sunk me, as i am a student LOL>. So i might be a few weeks until i can get to ordering a bit.
Thanks for your replies!
