Tommy great video & build! I could see that Charlie was thoroughly impressed.  He's coming around  Charlie is such the intellectual and design engineer. |

That's a very nice build there, well thought out and clean, my compliments. One thing I do see, it looks in the pictures like the belt pulleys are way out of alignment from motor to shaft. Bringing them into line so the belt runs straight will make the belt and the motor a lot happier, and they will live longer. Thanks Larry! Might be an optical illusion - I squared them up as best as I could do - visually though so I know they aren't perfect but not too bad I think. Check it with a straight edge. |

Tommy, there are some products made to spray into rain gutters available in hardware stores that might serve to seal that wood, but you might want to consider using bed liner for the job. I noticed your finger protectors in the video ... did you make them or buy them? Are they leather or something else? Thanks.

It washed off with the first hail/rain storm. Not sure which did the damage, but it did not hold up. Thompson's Weather seal doesn't last long either.  |

Ok, what about the stuff they sell to paint on the inside of evaporative coolers? Maybe good old marine grade spar varnish is the answer. |

Which Diamond Blades did you use for the Super Grinder?

One more question, Have you tried the Super Grinder yet? if yes was your drip system adequate to suppress the increased dust generated.

One more question, Have you tried the Super Grinder yet? if yes was your drip system adequate to suppress the increased dust generated. Henry It's not really a drip system per se - it's more of a forced stream of water when I open the needle valve. When I first built the recirculation system a couple years ago(?) I envisioned using an aquarium pump to send water up to the PVC reservoir where drip lines would feed the wheels. This didn't really work to give me the amount of water I wanted so I installed a valve that slows down or stops the flow and creates pressure in the reservoir. So to answer your question - yes the needle valves can deliver a tremendous amount of water - way more than I would ever need with every needle valve open at the same time. The problem that I've discovered with the design is the wheels are a lot closer to the front than I've been using so in order to get enough water on the wheels I end up taking a shower. I'm going to cut a few more cabs on it today before deciding what to do with it but something has to be done. |

My two wheel grinder has a rigged(by me) gravity drip system. The water in reservoir will last about 40 to 45 minutes before needing a re-fill. I anticipate increasing the flow for the Super-Grinder wheel to help suppress the dust and needing to fill the reservoir more often. Watched your video again and wondered if the Super-Grinder wheel throws more water due to being a bit more open-faced nature?
I have another 2 wheel arbor and 2 splash shields that I have never setup, may put it together and put it on a steel table and run it closer to garage door to be able to clean up better. I can deal with a bit of mess, just don't need any silica dust.

I've never used one so would appreciate any insights to how well it would apply to a super grinder. Thanks. |

Geysers wouldn't provide enough water to flush all the rock mud off a super grinder. With some softer rocks or real messy stuff I have to use both spitters on my Genie. |

For the Super Grinder wheel, one or two DVD's/CD's between each Diamond Blade? It seems that it might take two.
Thanks

That is a great idea Henry. I wonder if the plastic will quiet it down as well.

I used to have a link to a site that talked about building them, don't remember what they said about the DVD's or CD's. Tommy just built one so I was going to follow his lead. It would seem to put the tightening pressure on the Metal rather than the Kerf. Not going to put this together until mid-week at the earliest. My new 20 inch blade is coming this week and want to get the Big Saw up and running.
Too many rocks, too many machines! too little time!!
