Bob and All,
There you have the lay-up of the basis for the bellhousing pattern.
Notice the very thin walls in an attempt to obtain the lightest weight.

A lot of work still to go on this pattern, both inside finishing and outside ribs and flanges.
Although the MM sides have draft (taper for the foundry process) I will thicken them a little to allow for sides to be flat milled - easier to machine and
easier to install in the plane (Butch's idea !).

All in all this is the improved and lightened version as Butch took my original attempt and re-engineered it - that why it has taken so long.

Like I said; I will continue to update everyone as and when there is sufficient progress - OK!
