Thanks again George
I have signed up to Model Boat Mayhem but have to wait to be approved
I think I will be plugging and redrilling too. What did you "plug" with?
Regards
Bruce
Bruce,
As the holes were already tapped 7 B.A. I plugged them with 7 B.A. steel screws with a spot of Loctite 603, left them to set overnight and then flushed them off and with changing to 4- bolt fixing on 1.062" p.c.d. it gave me fresh metal to drill and tap into.
Bearing in mind that I also made 2- new cylinder covers with 4- bolt fixing.
I assume that the engine is for your own use, so you could tap the 5- holes out in the cylinder covers to a bigger size and glue in screws and flush them off , re-drill to 4- bolt fixing for 7B.A.
When you eventualy get into the pics on M.B.M. I also describe with pics my method of making built up crankshafts set at 90 deg.
Hope this helps.
George.
