Today is the day to put the quad mount together, the mid ring was very loose on the fwd 29 mm tube so I glued a strip of card stock on that, fortunately was wide enough to get the fwd ring also. When that was dry the mid ring was glued to end of the tube and allowed to dry, then the fwd ring and spacers were glued on and fillets added. I then carefully marked where the quad tubes will mount to the mid ring. This is a butt joint although there is a lot of surface area, there is an opportunity to strengthen the mount with split bamboo glued in the valleys of the 18s, passing through to be glued inside of the 29mm fwd tube. This does double duty since it closes the remaining gaps. Each piece was glued and held in place while it dried, then filleted. Last, the centering ring for the quad 18’s goes on and is spaced two inches from the fwd ring with a spacer that was on the laser cut cooling fin and spacer set. Last shot is the complete mount with the cooling fins dry fit.
