Forstner bits are a joy to use overall. I haven’t touched my spade bits in ages. Lee valley have a good selection for Canadians out there and shipping is free.

Fiberglass is hard on Forstner bits. If you want them to last, you may want to drill the skin with a whole saw, then switch to the Forstner to remove the core

With correct file &stone these can be sharpened in minutes. Creating more solid waste from an item with only a tiny part (edge) needing a little grind isn’t appropriate

Good idea— but I would rather use the cheapest Harbor Freight bits rather that high quality German ones.

I really like to drill the hole in the topdeck with a 8mm or larger bit and then ream out the rest with the dremel bit 115 using the hole as a guide. This leaves some topskin intact fixing the epoxy plug in place.
