To cheer myself up after the Forstner fiasco I brought the first baffle panel indoors together with the tweeter baffles to assess the fit of the tweeters / upper midrange units.

I’m using dainty little 3/8″ No 6 black self-tapping pozi screws from Accuscrews to attach the tweeter baffles; the screws for the front and rear baffles share the same through-holes so if they are much longer they will collide.

All is well! – I was particularly pleased that my 19mm cherry ensured adequate clearance at the back of the tweeters. These are secured by black M4 8mm bolts inserted through the centre of the opposing baffle, and gratifyingly the tweeters lined up perfectly with the pre-drilled baffles. I knew from the support / build forums that tweeter clearance has been an issue for some builders using 18mm materials. I have sufficient clearance to allow the insertion of small foam grommets between tweeter and baffle to insure against any rattles at final assembly.

I still need to drill the mounting holes for the upper midrange on this baffle – but first I need to cut the lower midrange recess and set about baffle two…
