only for the head. he's machined the rest.

Block:


center lock spindles w/threads (messed up)


"I had to grind a carbide tool to a perfect razor sharp point to cut the threads since they are only .0025" (.01mm) deep. The thread pitch is .2mm on a diameter of .080" (2.03mm)."

It's essentially a tube chassis DTM car ( whole chassis will be hand made from brass ( was done once, then changed, currently built w/ plastic until everything is done). Will have double A-arm suspension etc

/thread jack - sorry
