There is a name I haven't heard in nearly 50 years; my first watch as an 8 year old was a Waltham

Awesome to have you on board Lars!

I have made several fly cutters in a similar, although less advanced way. They work very well and in my opinion and the addendum radius is not all that critical. Thank you for the calculator it will speed things up. I think the projekt is very beautiful and I am looking forward to the start. Now you have a patron from Denmark.

Just a thought, something will be really wrong if Byzantium does not make the name cut...

Sure thing Ed, any time :) Depends how thin the sheet metal is and what its made of - if its much thinner than 0.5mm then it may be worthwhile to consider a punch rather than a broach. The main issue using a broach on thin stock is alignment - there should be at least 2 teeth in contact with the work at all times to maintain alignment. I say *should* because you can still make it work if you're careful, but its not best engineering practice. You can also clamp a guide above the stock if need be, and achieve the same result. As to tooth profile, not sure exactly what you mean by "smooth and flat" - but a broach can be pretty much any shape you want the final hole to be. Hope that helps!

Might be a bit of a weird question, and it's not related to the sundial at all, but can I ask about broaches? That square one you made fascinated me. Say you wanted to pierce and widen a hole in a thinner sheet of metal, not a block - would the profile of the broach be any different? Could it be smooth and flat or would it still be stepped?

Nice one Ben, thanks :)
