LS_Sonoma Posted August 15, 2012 Report Share Posted August 15, 2012 Why not use a pneumatic long board instead? 18" long by 3" wide. Quote Link to comment Share on other sites More sharing options...
coltboostin Posted August 15, 2012 Report Share Posted August 15, 2012 Many general automotive shops actually use a large belt Sander for surfacing......Not much different But I love the DYI Quote Link to comment Share on other sites More sharing options...
BIGGU Posted August 15, 2012 Report Share Posted August 15, 2012 seems right, alot of people use sand paper on glass to lap their CPU's for their computers.... not much different than this. Quote Link to comment Share on other sites More sharing options...

TurboGoKart Posted August 15, 2012 Report Share Posted August 15, 2012 I understand the concept, but if the head isn't perfectly weighted flat, won't it sand/resurface it not flat? Lol. I'm no engineer though.....just running off common sense. Sure you'll get a 'flat' surface, but will it yield even and equal compression across the cylinders? Or are you splitting hairs at that point (depending on the level of modified the engine is)? More importantly, if it's not leveling the head to the lowest point, but still 'flat' will it even sit right when torqued? Or maybe the video was the joke and I missed it cause I figured someone on CR will actually do this.....lol. Quote Link to comment Share on other sites More sharing options...

TurboGoKart Posted August 16, 2012 Report Share Posted August 16, 2012 Yeah but you're talking about basically forming something as it cools there. That makes sense as you still have some malleability left at that point. Quote Link to comment Share on other sites More sharing options...

TurboGoKart Posted August 16, 2012 Report Share Posted August 16, 2012 Yeah, I think that's what I was getting at. For the normal DD user, this should be ok. For the performance minded person to the extreme racer and beyond, this should be nothing more than a good LOL video. Quote Link to comment Share on other sites More sharing options...

I dont know-I just put a motor together with a rust block that has an unknown deck surface and a Head I pulled out of a junkyard car 2 years ago. Billy Bob's surfacing would have been an improvement. :lolguy: Quote Link to comment Share on other sites More sharing options...
unfunnyryan Posted August 16, 2012 Report Share Posted August 16, 2012 ?? Computer processors have a metal heat spreader over them that protects the actual CPU die. Some people will either remove this or shave it down to make it thinner/smoother to improve heat transfer. Same thing is done to the surface of the heatsink. It's at the deepend of being a enthusiast though. Quote Link to comment Share on other sites More sharing options...

Richard Cranium Posted August 16, 2012 Report Share Posted August 16, 2012 A buddy of mine bought a car for cheap with a warped head. We threw it on a belt sander and reinstalled it. It's still driving today. Is it the "right" way to fix it, no. But the head was already warped, what's to loose if it doesn't work? Quote Link to comment Share on other sites More sharing options...
