Ernest, I saw a video of similar method of lapping the housings - they used lapping paste between two housings on a slow running mill with a cam in the chuck. The cam pushed the top housing around, there didn't appear to be any pressure on the top housing. It might kill two birds with one stone, I'm thinking of doing that myself. Just a suggestion! George (down under) I cleaned the rotors by soaking them in a MEK/laquer thinner mix overnight. Blasted with 60-grit silica at 80psi in my homemade blast cabinet, then brushed them down with MEK again. Sprayed with TechLine's CBC1 and baked in the Wal-Mart special toaster oven. I sprayed them down with WD-40 to keep the rust at bay until I can reassemble the engine. http://ernest.isa-geek.org/Delta/Pictures/ToolsBlastCabinet2.jpg http://ernest.isa-geek.org/Delta/Pictures/EngineCeramicCoatingBaking1.jpg http://ernest.isa-geek.org/Delta/Pictures/EngineCeramicCoatingRotorThermalBarrier1.jpg http://ernest.isa-geek.org/Delta/Pictures/EngineCeramicCoatingRotorThermalBarrier2.jpg I'm now in the process of lapping the side housings. I'm spreading valve grinding compound onto the housing, and then pushing it around on a glass table top. Results are good, even if the process is somewhat laborious. It leaves a roughended texture, which should be just about right for applying TechLine's DFL1. The housings are to big for my toaster oven, so I'll most like convert my homemade blasting cabinet to a homemade oven with a few halogen light bulbs. Techline's coating cure at 300F, which isn't difficult to attain and maintain. -- Homepage: http://www.flyrotary.com/ Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html -- No virus found in this incoming message.
