Howdy folks, First another heads up for you Covington 10" saw users. My saw seized up again today. Turns out you have to check the allen screw that holds the vice crossfeed rod really often as it easily vibrates loose. When it loosens, the rod gets a little bit of forward and back play in it so the rock is pushed away from straight and binds in the blade. I was away from the saw and almost fried my drive belt when it stopped today. These saws really need to be babysitted constantly while you are cutting. No more cutting cabs or doing chores while it runs and shuts off automagically like the old days. Anyway, I did get my blade dressed and then cut some of the new toenails to get it even sharper. This cobble was two tone and I kind of like these slabs.....Mel

That saw has really been a challenge to you! Just a thought - maybe some of the lighter duty loktite on that allen screw might keep it from loosening up but would also allow for adjustment if needed ? I still love that toenail stone. Those are pretty Mel! kinda of reminds me of orginized chaos gr

Mel, that is really a pretty stone with dual purposes. Good for the blade and easy on the eye.

Gr: was talking to Brian the Covington rep and he suggested if it keeps shaking loose to use locktite too. And yep, this saw is definitely a challenge.....Mel

That's a good looking stone. I don't see any around here that color or with that density of toe nails.

Mel, I think you've said you find the "devil's toenails" in the gravel pile. What is their original location? Ie, where do they occur naturally? I think they are really interesting - wouldn't mind having one in my collection.

Mel Thanks for the tip on cross feed rod. That's one thing I have not checked. I have had the problem of it not cutting straight. thought it was a dull blade. this may be it. Nice toe nails. Mike

Tom: The toenails comes originally from a gravel pit ( I think the only big gravel pit) in Eagle Pass, Texas. Funny though, I have to dig back into the older parts of the pile ( where the fire ants live) to really score the toenails. From the recently arrived stuff, I only find a hunk now and then. Same with the Rio Grande agate. One load will be rich with them and another almost nothing. I have a theory that as the pit goes deeper they run out of the agate/toenails layer and then when they start a new top layer, it all starts showing up again. Matt Dillon makes most his Rio finds above the river on the higher older terraces.....Mel

Mel, thanks for the information on the saw. My new blade arrived and I still have to get the new table top but your information is really helpful. Thanks. And you're right - Brian, over at Covington has been really helpful in getting me the parts I need. Oh, and great looking pieces as well

Paul: When you take the table top off, if you have hands the size of mine, you'll have a heck of a hard time getting the table hold down screws back on the way the manufacturer put them on. Go ahead and make it easy on yourself and run the back two bottom to top when you reinstall them as you'll have a much easier time threading those tiny nuts and washers back on that way. Also remember, saw blade hold nuts thread the opposite way ( not righty tighty) when you go to change out your blade.....Mel
