No sooner had the dust settled and DuraTek dried on my wonderful DR250s and I was back in the shed making more sawdust with the T39s
I got the sides and panels 1 & 2 for both boxes completed. I might be speaking too soon but these are a walk in the park compared to the DRs
. I recon I'll have them finished by the end of the week (If I get more timber in time). The only thing I think it is worth commenting on is that I didn't bother with marking out both side panels as once the second side is ready to go on it should just be a case of putting it in position. I have not used many fastenings so far because I have sufficient clamps to hold everything in place while it cures, thus eliminating the need for markings for fasteners.
You will notice that there are four extra guide blocks around the driver anchor. These are used to position the anchor in place with the speaker firmly attached to it with ALL the mounting bolts fastened. Once it is perfectly aligned, the speaker is then removed and the anchor plate glued in position, aligned by the blocks.
I bought myself a little bit more security by putting a self tapping flat head screw next to each T-nut. The drama of trying to extract a cap head screw from a T-nut that has come adrift does not bear thinking about
, I was working with a combination of the plans and the 21" Sketchup model that has a single brace. I realise that the length difference is only 1.5" but I suppose the resulting area is significantly increased. If Bill could please offer an opinion it would be appreciated!.
