Hello Gary,

Just seen this thread, (gotta love a good build thread). I agree with the earlier comments on machining the cylinder, as it's easier to align and gain measurements for everything using the machined flat valve face on a surface plate, to get the correct distance for the bore, and also makes aligning the bore and cylinder end parralel, by using the machined face against one of the jaws. You seem to have done a good job on the cylinder dispute it's poor quality of cast. Maybe you had done this during cleanup, but just run a small needle file down the steam passages as they may also be quite poorly cast so won't allow passage of steam through.

With regards to filming with a camera tripod under you, perhaps maybe a camera mount that attaches to the rear of the cross slide either via a magnetic base or to the tee slots in the cross slide. Either way I wouldn't worry about your filming as it's showing all the details needed. (Also American pie in the background was actually quite pleasant to hear).

Keep up the good work and I look forward to seeing more progress on the build. 😊
