The beginning of a twin

[GraysonTaylor]

I've had great results with a large flush trim router bit on a good router table.  Ruff the cut, and go to the router table.  No need for sandpaper and you will never screw up your template by over sanding.  The inside 90 degree corners will need to be hand finished.

2 sets of rear sponsons built yesterday at the Mark Bullard shop.

Also the roter was put to use.

The top was glue on the tub WHILE IN THE JIG.  Then the compartments were rotered out using jigs.

Brass tubing is for the pipe pressure

Doc 

will you order new 2019 CMB91 M-line red headed more powerful than CMB EVO ? 

 

[dr gary turner]

Allan, 91M red head?

 

[ALLAN YUEN]

Allan, 91M red head?

 

[dr gary turner]

Are they available in the US

 

[ALLAN YUEN]

Coming soon 

will you sell CMB EVO ? LOL.

I don’t like four bolts on head because weak compression 

better six bolts head more seal and strong compression 

I will order one and will order build new Special  SGX “single engine “ from Andy Brown 

 

[dr gary turner]

No will keep 101

To answer the question, I have no plans to bring these to North America.  I have talked with Mauro about this motor and it is made for only square drive / gear drive applications.  There is no bearing retainer clip on the front housing that prevents the crank being pushed into the motor.
