So today after 5 Ops, They found a tutor deep down in the neck muscle and growing around the neck bone --sounds exciting ,hey ? . So, out came the husquvana and makita grinder . No, just joking .. Radiation will fix it ,they think!!. Back to the cutting holes,, I agree with you ,that stainless really blunts the old hole saws ,and they are not cheap. I thought of cutting three ,say, 30mm holes within a circle ,but leave ,say, a 5mm between them for a bit of strength . Cover them with expanded Al mesh and bolt the fan unit under that. I'd put a temp and rpm adjuster on the front cover to set it at the best temp and rpm. for noise,Etc. The Torodial will go back where it was originally ,just a bit more bulky..   You must be finished most of your fiddling ,cause I don't see you or your work on the forum lately ?? all the best , mate . Aaron is doing a good job and he's always busy on his block , handy guy , has built all his stuff . Cheers, Bruce Bushboy
