Paul,

More photos and illustrations from you - Thanks - I did get to see, photo and ride in the KIS Cruiser with the Wankel engine by Bill Schertz - Very nice ! - Bill has moved from Illinois to Montana -

In the recent photos it looks like the outer shell components were hogged out of the solid - Is that a fair appraisal - Would you comment on that approach vs using castings ?

I'm guessing that the toothed belt drives are probably more suitable for the lower HP applications ? - Would you comment on the relative advantages and disadvantages of the belt drives vs gear drives relative to the HP of the engines - Or any other comments relative to the two - Cost - Service - Lifetime - Reliability -

 I've attached one of your photos to this message - Never seen an anvil and a dial indicator used together before !!

I am a big fan of tig welded thick wall tubing for the gear box.
Beats casting material and cost less and weighs less than a casting which
if you are  lucky can be as thin  as 1/4 wall :)

The belt drives are good in some applications like the Coot where you
want to lower the CG of the engine. Not so good for most airplanes as
they add a lot of bulk to the package and leaving less room under the
cowl for needed  heat exchangers.
