I was wondering how you would make a rock saw leakless. My saw is a 10inch unit with a cosy well for cooling around the blade o the left as shown below...the frame closes metal on metal and leaks a lot of water. It is very messy and potentially dangerous. I'm wondering what you might use to make it watertight as the blade stirs up a lot of water and mist. I was thinking maybe something like some sort of gasket material? any ideas Here is the saw Charlie

I have seen a product advertised on TV for rain gutter repair where they actually put a screen door in the bottom of a boat, spray it with the product, and it is water-tight. That's the good news....the bad news is that I have no idea what it is called. But, maybe someone else remembers the ad and the product name. It should work great, if you could clean the water tank area. Sorry for the tease. Maybe check with a hardware store?

Looks like the base is cast and the walls are maybe what, Charlie, a quarter inch thick?
1. Self-stick weatherstripping. Probably won’t stick for long or hold up too well.
2. Thin, uniform bead of silicone caulk can work as a gasket. Give it plenty of time to set up.
3. Liquid gasket. Put a light coating of grease on the matching surfaces of the underside of the top so the base of the saw doesn’t stick to the top after the material sets up.

I would try cleaning the tank top and gluing in a cork gasket. Available at any auto parts store in sheets and cut to fit. Then. if you don't fill past the cutting rim you should not have much of an issue. Every saw out there will leak a little somewhere though.

OK Charlie, I really felt bad about trying to tell you about something that I didn't even know the name of. It was driving me crazy, but with a llittle effort on my part, this is what i came up with. It is called FLEX SEAL SPRAY. Here is the url. ( hope it is OK to show...I have nothing to do with the stuff, and don't even know if it works like they show). www.getflexseal.com/?tag=im|sm|go|tm&a_aid=011&a_bid=a4cc8494I think it would be worth a try if you can find the stuff. Good luck! "grizman"

that stuff does not work like a gasket. it would only help if the saw was sealed up after each cleaning. asls it will not help around the arbor where there may not even be full contact.
the cork idea, and more careful fill level are best ideas

I'd try a dry gasket, cork or regular stuff, without anything liquid like silicone. That will setup and make it a pain to get back open and when you did you'd have to scrape it all off.
I can't really tell by looking but you might consider a 4 sided light gauge sheetmetal box that would just sit in the bottom tank and extend above the tank by say 1/2" (as the upper tray looks like a 1" lip in the pic) and that would block the seam everywhere except the go-thru shaft. The shaft area could always be a problem but you could experiment with things like dense felt and probably stop most of it.
You could also put the sheetmetal on the top part but then you'd have to figure out how to attach it and im not normally trying to figure out how to glue metal together.
If you wanted to try this idea I have a sheetmetal brake and metal I would trade a small box for a slab or something. Only problem is you'd have to remove the shaft. And then notch out for it.

PS try the gasket first.

I think all manufactured saws have either a cork or neoprene gasket glued to tank that is compressed by tightening the top. I hate to sound like a parrot but most saws that throw coolant are overfilled.

I have a 8 inch saw that I run water with and the seams are all welded and water tight... I have seen silicone used in a saw to stop a water leak and it worked well.. the guy a 1/2 inch wide putty knife to really workit into the corners and as far as cleaning the saw, used a garden hose with a cone spray to remove the rock snot that built up in the saw... I use a garden hose too... doesn't need a lot of pressure (full stream) to clean either..... also a plastic tray as mentioned above would work as well but will leak a little as the water will get sprayed... I would look for a plastic container that would cover most of the interior if going that route and didn't want any leaks... another item to try is the rubber polymer that they dip pliers into to coat the handles... coating the inside of the saw with a coule thick coats of that would probably do the trick too...
Also anytime the coolant touches the saw blade it will throw coolant out.. that's where the blade cover comes in, it directs the water/coolant down onto the saw instead of up into your face... I also have a sheet of lexan 12x24 inches mounted to the end of the saw where I stand in case I cut something thick enough that the spray goes over the splash shield and also to prevent any chips from flying out and hitting me!!
and just so you know... I take my saw outside and prop it against a pile of blocks and spray it out with the garden hose, careful not to get the motor soaked, then let it dry in the sun for 1/2 hour then put the lid on add clean RV (pink) antifreeze/water (50-50) mix and am good to go for another couple weeks or so..... just my dos centavos!!
looking at your picture again... it looks like the top of the saw closes over the sides of the saw and if this is true you will gets leaks as the water running off the edge will go onto the ground... on my saw the sides are about a 1/2 inch higher than the top so the water runs to the edge and then back down into the reservoir to be re-used. If this is the problem there is nothing to do except to prevent water from running down onto the ground, except have a new tank built for it.
Now, if the lid closes inside the outside wall of the tank and you are having an issue with water running off the saw, then it is simply a atter of raising the sides above the deck by 1/4 - 1/2 inch to keep the water running back into the saw... plastic like plexiglass or lexan would work well and a littl silicone to seal the 2 surfaces and violla you are good to go!!!!
Of course I may be missing it altogether in which case I have no idea what you are talking about and I will go sit in my carner and finish talking to my rocks !!!!!!!!!! :cheesy:

I'd like to hear more details of what the situations are that are leaking. Is it the area between the saw top (table), and the tank/frame below? Having a lip that extends down from the top component on the inside will solve a leak where two surfaces currently contact without overlap. It doesn't take much of an internal lip to deflect the spray, drips, and drops. If you are talking about areas around spinning shafts, I'd go the felt or even plastic shield route. Keep talking if we have not addressed your situation. Tom

I had a saw like that once. I used a cork gasket around the top and used heat resistant gasket sealer to stick it to the base. NONE AGAINST THE TOP. and it had a 1/4 inch felt washer for the shaft. It was split to be able to twist it to go over the shaft. Ken

If your worried about electrical shock, a good grounded motor plugged into a GFI is the only way I ever run any equipment that uses water. I also mount the motor on a base that sits higher than the table that the saw sits on so the motor doesn't sit in a pool of water.

I would install a rectangular sleeve in the lid that protrudes downward 3/4" or so below the seam when closed. This would be a barrier to oil or water having a quick exit route when splashing around. This is how the lid on my 14" slab saw is designed. Lynn

Try stick on foam weather strip from the local hardware store . It comes in various thicknesses and will make for a cheap fix. It is usually available from 1/8 in. on up.

Lowes near me has a U- Shaped weatherstripping that is like a spring so it slips on and stays there... if you ran that around the edge of the tank it might work, but it might cause the lid to sit at an angle as it would be slightly higher that normal.... this may or may not impact your cutting, only way to know for sure is to try it... luckily that stripping is cheap.. about 6.00 for 8 feet. \ good Luck & keep us posted !!
