Bill,
Yep The steel centre section is bulky - has to be, but it's not overly
wide in the areas which take the mounting bolts of the stationary gear.
That would concern me in aluminium as to me it would seem to lack strength,
in the softer material. I can only assume those areas would be reinforced
somehow in a aluminium housing
How do you get around the O ring area, just use thicker material in the
wear service side or braze on a thickening plate in that area. The through
bolt areas would be tubes with the channels tacked on before brazing I assume.
Other areas would be supported with spacers where needed and the through
bolt tubes and channels would also act as spacers.
How am I going am I near the mark with my assumptions. No need to answer if
there is a commercial in confidence condition, just thinking out loud. I find it
all very interesting and indeed exciting when thinking of the weigh
savings.

George,
To
tell the truth I didn't know about that (trying the plates) either. What
Richard has done is a fine piece of work. The fact is that the all steel
brazed housing is lighter supprised me as well. The need to mount the
stationary gears is one of the things that also adds weight. BTW you don't
even need to use chrome molly steel. Any decent low carbon will do. Remember
you are only replacing cast iron.

The steel plates (lightened) are actually lighter than the sandwich
steel and aluminum plates PSport actually tried it.

Bill ,
I wasn't aware of PS considered this concept and actually tried it , I
was half way through this process , some time ago, but when I machined the
wear plate out of a housing, I soon realized that there wasn't enough weight
savings to warrant the cost so didn't proceed.
