Sharkey, yes I have a small bottom bearing spiral bit used to do inlay work on furniture that will cut up to 1/8 inch soft non-ferrous metal, like brass, copper or aluminum. You can get it from www.woodcraft.com or www.rockler.com. Got to get the one with the eight inch spindle so you can use it in your Dremel.

And???

Well the second set of 372 cases had a slightly higher deck height, using three gaskets I am right at 0.024 (0.023 left 0.025 right). The 272XP piston works fine with no modifications. New bearings and seals in the case, all buttoned up ready for pressure/vac test today. Have both the stock 12B and XT intake, going to start with the 12B and use the low filter and top because it is what I have. Have several mufflers already done with 0.800 ID pipe. Best you can do on the muffler mods is 7th pulse third would be better but due to the interior dimensions of the muffler 7 is the best you can do. If you reduce the depth of the muffler be 0.500 you might get to fourth order harmonic but who knows. My bet is that the 0.800 pipe is a waste but will try it and see. Guess is that 0.374-0.500 will be better.

Bob (Spike 60 ) is coming up tomorrow to help with the logging work. It's a 3.25 hr drive for him! We might do some video time. I got that "Fugly 350" running a bit better. Changed out the carburetor flange, rubber "boot" inside all the intake manifold & stuff. And put a new "steel clamp" on it as well. Didn't finish the cylinder yet but it running really strong right as it is making me reluctant to fix what's not really broken, BUT wanting to complete the experiment. I sort of talked it down on the video...mainly to tease Bob as it will eat up any 350 variant I've run to this point in time. He has a 346xp top end on a Jonsered 2150 that's a favorite work saw when he comes up to break down tops. My goal is/was to have the Chinese fugly 350 match that saw. Pretty certain I accomplished that goal without going any further. I've put two days of work time on the saw dropping & topping trees, and it's a solid build...
