for the current project i need to screwcut m19 x 1.
I tried to grind up and internal and external screwcutting tool, using a gauge to get the angels at 60 degress to screwcut it put had no sucess when trying to screw the two together.
My guess is the two tools i ground up were not the same...
heey guys quick update ive looked more closely over the drawings and ive found out im missing quite a few dimensions on the cylinder, and few other things. So for now the project on hold till i get some more.
However on a brighter note ive got some drawings from hom shop machinist i think it...
There are some problems im having though because of the size of the engine i cant use a boaring bar, i tried to grind one up but it just chattered to much. For example to do the main bearing i would of idealy boared it near size then ream it out. instead im having to use a drill then ream it...
Glad to see your still at it ;D .
One question, you say it should be made out of ali. what are your reasons for making it out Ti . ive never worked with it before.
Best regards RR17
A questions for you guys out there is it nesscary to lap the main bearing and the crankshaft together. Or can i get away with a good finish and nice fit?
Any comments would be helpful.

Owch that sucks but at least you wont have that happening again on your third.
I look at it this way if you make a mistake, and then remake it but make a different mistake than last time, you've made progress.
And eventual you will finish it but with loads of lessons learnt in the progress...
Right guys back to where i was and a bit further.
As you can see the new crankcase has been made with a near finshed fuel tank. Also i have finished the carbaretor off on the Crankcase.
Best regards
