    I to have the book but I like drawing sheets in the workshop. As for CAD I have tried in the past and it’s beyond me. A pencil and a bit of paper does me fine.

    Wanted Bentley BR2

    Hi all am gathering materials to build the Bentley BR2 rotary engine, have the book by L K Blackmore but was wondering if anyone has a set of drawings for the said engine. On that line has anyone started one and it is now lingering under the bench unloved and would like to sell it or parts on.

    Hold a gear for cutting?

    As you did before make a mandrel to fit the gear blank but long enough so when in the chuck the cutter will not touch the chuck. You will also need a support on the outer end to make it rigid, very much like a tail stock.

    Forrest Edwards radial 5

    My solution is simple, I just connect it to a 25amp 2 volt battery, and no problems with plugs burning out.
