P.S. nice guard dog!

Hey brian

Im just learning at the moment and i have much to learn too , the last time i touched a lathe was when i was at school .
Im in dire need of some decent tooling but i need to earn some more pennies first , but a least its up and running and iv had chance to have a play
The dog is the mrs pet , or should i say baby , he is into anything that moves

how do you hold the head on a lathe?
do you screw an axle in the spark plug hole?
any other ways to cut a head besides on a lathe?
i'm going to get it done but want some info before i go to a machine shop and see what they suggest to do and how.

When i had mine done the guy screwed a mandrel into the plug hole then mounted the mandrel in the lathe chuck

All I know is I don't know. But I do know who does know. Fred Overstreet, FM Powersports, Decatur Ar. Fred explained the squish band info to me, which I quickly forgot everything he said. But he built me a 275 motor, ported for low end/midrange, set the squish, set the compression where I asked him too, (I have a problem kickstarting due to a bum leg, so I didn't want real high comp).

Best running bike i've ever ridden. Smooth, fast, torquey, no "hit", unless you would say the hit now starts at idle. I just told him what I wanted in motor characteristics and he made it happen. Fred is top notch, and he is also good at explaining the complications to an uninformed guy like me. I just wish I had remembered more of what he said.

Fred is "Fred1956" on this site. I think he has an ad in here somewhere?
