I am going to put my 18" Covington saw on the local Craigslist and try to sell it. It works perfectly, at least as well as it is capable of working. It has a near-new MK303 blade. Any idea what I should ask for it? I am the second owner, saw was made in the 60's. Where are you located Mike?

Some good ideas here. I should have noted that i only use this barrel for coarse grind in stage one, so the contamination issue would be moot. I'll have to look into Flexane. Thanks guys! I've melted plastic on a hot plate outside to repair my UV-10 barrel. Used pieces of a wet dry vac extension wand (black plastic). Not sure what type of plastic but it's held up for 3 coarse runs. When you melt don't stir too vigorously or you will get a lot of trapped bubbles. You have to be careful that the melted plastic doesn't melt through the barrel. I placed my barrel on concrete & just had to recoat the bottom. You're barrel is different, you may be able to wrap lots of aluminum foil around the outside bottom sides to keep the plastic from melting through.

I can't take credit for it. I just noticed the cover in my stack of unread mail on my desk. Anne, small world, I get the digital edition of this magazine although I haven't looked at it.

Must be silicified if a file won't bite into it. This means the calcium carbonate skeleton of the coral has been replaced by silicates thus fossilized. I disagree that it is fossilized. If it were fossilized then the pores of the coral would also have filled in and it would be very unlikely to be that white. In some cases fossils form in limestone that can be removed by acid exposing more of the silicated structure. But do to the attraction between calcium and silica again the pores would have also been filled in with silica during the silification process. The other way to tell would be to put a drop of acid on the coral. If it were fossilized then no fizzing will occur. If it fizzes then it is still unfosilized calcium carbonate. Agreed

Sweet Rob, looks fun. The audio was way creepy though. Used to do a lot of knee boarding & slalom skiing back in day before wakeboards existed.
The video cut out just when it looked liked you were gonna wipe out. I'm sure no one on here wants to see that...

cathys, it's difficult to ID based on pictures alone but here are my guesses: middle - chert right - quartzite bottom right - flint bottom left - quartzite with Quartz veins The other three have an agate look to them, unsure on these.
