Well, I received my cabinet from vaporhoningtechnologies. Model VH450 industrial/production line. It's a smaller unit with the same power as the big ones. Enough space for anything motorcycle related. To put it to the test right out of the box, I found not just the crumbiest set of engine cases I have, but it also happens to be a set which is in the top 3 of worst condition cases I've ever had in my hands. These cases came from an engine that was open to the elements, the piston froze to the cylinder so bad that I had to use a 5lb hammer and about 30 min to beat the piston out. Clutch and stator plate was off, and it looked like it was stored on the dirt that was wet often. 100% of all steel internals were throw away other than the clutch drive plate and shift shaft. I kept this engine because it was an H and matched to the H frame I have, and thus will put together at some point. If this were a regular 3-speed model, i would have throw the whole thing right in the trash. It was completely caked up with dirt, which the vapor hone does not do a good job with, but I used a small screw driver and pick and loosened up anything that was caked on. Here are the results after 45 total min of work...blasting, scraping, picking and repeat. I don't think you can ask for better results. The cases look like they were just cast. It does not change the surface texture of the original casting. I'll have to do a small weld and feather on a very small section of gasket surface, but seriously, I wish I had this 10 years ago when I was cranking out an engine build every month. I may offer this as a service once my jeep project is complete.
