Re: Mike's Build Log

Just wondering if a "hatch" could be cut in the side of the CC to remove the support material then tig welded back up again? on the edge of my seat waiting for some start ups! ...

Re: Mike's Build Log

These are absolutely awesome, so incredible that this is even possible. :D Great to chat earlier Mike. So much ground to cover. Looking forward to hearing everyone's input ref augmentation. Particularly if anyone will try steam boost, liquid fuelling and so many more things to try out!!!

Re: Mike's Build Log

Way to go I think, - John Wallis tried a turbine on a PJ once - it worked but not enough power for what he wanted.

Looking forward to seeing more of this!

Hi Mike, yes propane - very tiny amounts - start on alcohol then switch over to gas :D

Re: Mike's Build Log
