Another day on the baffles.... This is the rear baffle.
The front RHS looking back over #2 & #4 cylinder.
The front LHS looking over #1 & #3.
Then we moved onto the baffle / cowl gap, this is meant to be between 3/8" and 1/2" - as I'm seriously thinking about a plenum so want as much height as I can get..
A local pottery club had a source of fine grain clay.
It is sort of similar to putty to work with and I put a bead of clay along the top of the baffles.
Then the upper cowl was fixed into place and pressed firmly down.
That provided the shape of the cowl, but it was difficult to provide a shape line due to the 'width' of the clay.
Therefore this was trimmed along one edge.
 
It was then easy to mark a pre-set distance down around all of the baffle.
Remove all the clay, wash and dry
A Dad worked around the edges with a 'flexi-curve' to produce a reference line which should have 3/8" clearance all round.
The LHS floor baffle, needs bending and trimming, I used the cardboard template method again.
More trimming and bending.
The resulting baffle part looks good, although it will probably need more of a downward bend, more refinement can be completed as needed.
