only bits on engines again :( not full builds.
i cheat, i start with a bought turd and attempt to polish it.
:)
oh well.
lets see, cnc bits... i made some heads... high compression heads
one finned, one externally finned via water and radiator :)
so, the fins...

ended up being a whoopsy, shoulda stuck with my layout using a 6mm, instead of getting silly with an 8... basically worked great until it overheated to the point of autoignition :)

had some fun with trying thermo siphon at first, with mixed results, sometimes fine, sometimes not. temperamental. tried making a pump. didnt take any pics, which is just as well cus it didnt work! the next one with a direct drive will!
one time i rode back from a friends, cold night. at the time, i had a teepiece in the line. that wasnt so good as it would stop flowing, boil, and the steam in the narrow tubing formed one of those "airlift" pumps, and spat all the water out. so anyways, it started spitting, and i popped my finger over the end of the tee. at this point it sucked in as it formed a vacuum. the rest of the ride home, with my finger sealing the vent, it was boiling off at reduced pressure, and condensing in the radiator, with no signs of overheating. a perfect vapor cycle thermo siphon!
it didnt do it the next day when it was warmer :(
i made some tuned pipes!
now i need to cnc a plasma cutter to make profiles economically :)

oh, and lastly... i made this spherical boring attachment for doing the combustion chambers in the heads cus my lathe is still in manual mode :(

still needs some tweaking but the basics are there. tool mounting is the tweaking... but it works! no chatter! no slop! :) and it has quick action indexed fitting/removal ;)
the cnc thing is getting easier. the designing is getting easier. im actually starting to make things that look like what i envision! and they go together! with the possibility of repeating them!
now im just waiting on this chunk of 600mm I-beam from my mate for a tub/stand. i need coolant. i need air. i need a cabinet! the floors covered in six inches of litter! everything has aluminium stuck to it! yucky!
then. then its a bigger project.
vtwin. for mah pushy!
