It's been a busy week - or however long is is since I last made a contribution to this organ.
I printed a plate the same as the one I needed to weld to the end of the plenum & checked it for size, shape, would it fit on the plenum & block all the holes etc, then I checked it could be cut from the scaffold foot my brother had given me - all was good, so I drilled & tapped the holes (using the printed one as tooling, I marked the edges & cut it out, then took it to my brothers & mounted it in his lathe to cut the big hole out. Then he welded it on for me.
While I was there the printer was working again making the adaptor block - this is the thing with the cunning airway through it so it was quite interesting to watch (ish).
^^ That's like a time lapse of two DAYS of printing. The "tracks" round the airways are recesses for the original Ford seals.
