Thank you for sharing your experience with cutting wood with small end mills.

...I clamp the bow head using...often just 1/2" packing foam glued to a wooden backing...

I like the foam idea.  I have never set up a bow head in a milling vise.

Very interesting.

I tend to agree with lots of that, but Bob Smith epoxy for exotics is quite thin, comes in slow,medium or fast set times,clamps well and is like 50 bagillion times stronger than ca for permanent repairs. It is the only epoxy I would use for such things, particularly the slow set

Never heard about this brand, which one is for exotics, as i can only see slow medium and fast??

I use Hxtal NYL-1 optical epoxy but it takes ages to dry in the UK unless the weather is very warm and it is about the thinest epoxy ive tried. It will wick into cracks especially if you warm the joint a little.

It's now called "oak and teak"....the application calls for an initial application {you get lots of time} you apply, pinch the crack, maybe use a pallete knife or a boar hair to work it in, then you apply a second application, the first soaks in,It's so strong, works well on oily exotics
