Sub baffle/t-nut sections added(grab adhesive + not overly tight g-clamps!)
New longer bolts sleeved before application of epoxy filler.
After drilling out 3 screws with their heads snapped off(!) that were protruding by about 1.5mm from the base of the cab and just enough to give you a nasty scratch.... I decided to fit 50mm plinths.
Proper gasket fitted
Stink pipe port and plinth painted, tired and stained cone surface refinished (to match Monitor Gold replacement cones) a la Kenrick Sound Japan.
Much improved. Some cnc'd Tannoy lightning badges on their way from Fraserking of this parish will finish off the grills nicely.
Will do more work on the enclosures at a later date but looking much better.
