Thanks Carl!
Well started the day in the shop with a boo boo.

Ooops got to be more careful tightening the fittings.
So since I had to get out the glass tube again I decided to go forward with number seven and get the sight glass fixed in it at the same time.

Then on to the whistle.
turned up main body then clamped on mill at an angle and use dove tail cutter to cut the notch then take back to lathe and drill main air hole to the notch.

Turned up the shell and cut notch with a ball end mill.

Components ready to be assembled.

Use a ball bearing to peen end of valve shaft. Note I used a hard drive magnet under to hold ball in place while smacking the ball.

Valve shaft peened and in place.

Weeden number 6 done whistle in place.

It was extremely nice outside today so quit early and went walking my buddy Rowdy (my boxer) was wanting to go. So didn't get much else done today.
