I would HATE to pick up one of those ones with the circular saw blades the wrong way. Makes me think of that TLC show where the guy (ceramic) cuts off both hands while doing a home project.
Those are some sick slicks......I'd be scared those things would jump off the "raceway." Kinda reminds me of junkyard wars... I can see it now.... Dr.: And how'd you cut your hand off sir? Guy: ummm....well....I was racing power tools. Dr.: Racing power tools? Guy: Yeah, but my rear axle broke off and my sawblade slick flew off and nailed my right hand
LOL! Believe it or not, this was a series on TV for a while. I know because I actually used to watch it and laugh my ass off! I think it was on the outdoor channel IIRC.
It was on tv for a while. I seen a few episodes. That's wild. I wouldn't mind trying to build one....LOL
