    Your attention to detail and precision are the best that I have ever seen! Not many machinists are as methodical as you are. You always take your time to make sure it is done correctly! Keep up the great work.

    Another nice one on the 90 twin Dale 👍
    Your eye for detail is amazing. The meticulous setup of the boring and the post process of honing, deburring and finishing, flatness checks are good lessons of precision. Looking forward to the final assembly. Thanks

    Another Great video Dale. I'm sure you have probably shown this in other videos but it would be good to show as the 1st step how to make sure the head on the machine is perfectly square to the table with the Indicol / indicator just in case it would be off a little it could bore on a slight angle. Have a Great day sir.

    • @montana2strokeracer
      @montana2strokeracer  3 місяці тому +1

      Hey Mike, yes, I did talk about tramming, not sure if I showed it. My thought is, I would leave that up to the machine shop guys. I don't want to turn my channel into a machine shop channel. My thought has always been to show machining as it applies to classic motorcycles. IE making parts, repairing parts, crankshaft repairs, cylinder boring and you see where I'm going. I just hate to chase off the folks that come here for motorcycle stuff. They are the ones that have made this channel.

      Hey Andy, I don't know anything about putting up links. But I can give you the part numbers, matter fact I gave the part number for the head in the video it is DBL-203 made by Criterion, I however would not buy a new one, they are close to a thousand dollars. I bought mine used from an equipment dealer several years ago for around 250.00 if I remember. The boring bar is from Mesa tool it is the 3/4 x 6inch TPGB.

    Could you sometime take a cylinder and shoot water into the different ports to show everyone that the ports are designed to direct the incoming charge to different parts of the cylinder and swirl the charge to help scavenging. Just a thought.
