How do you get the water to go back down into the hole where the blade is?
I have the model J and the main surface just hangs out and isn't directly over the well. I don't have a cover for it and I use water. It seems like the water and sludge stays in the front corner and I have to keep a sponge there to soak up the excess water.
Help

I would see how level the top is and use some shims to level it or maybe even make it slightly higher in front to keep the water in back where it can drain back into the sump.

Some folks drill six to eight 1/4" or 5/16" diameter holes thru the top table to aid in draining coolant back into the slump. Larry C.

It hangs past the slump and the only part over the slump is immediately around the hole of the blade. The trim saws at the lap lab have the whole table over the slump and there are holes and a slit closest to me so the oil goes back inside, but the rock rascal does not have this. Also, if I try and shimmy it upwards it will just drain to the rear. I think it's just a bad design overall of this piece

I just pulled the table off mine. Inside the rim that fits into the tub there is a 2 1/4" x 6 5/8" area that, if a few holes were drilled through, would help drainage a bunch. These could be drilled from the underside of the table so as to insure not missing the tub. Lee is right with his comment too.

So I made some holes and after thinking about the whole thing my table top may not be level (reason for water pooling in the area nearest me). Another question: In the photo below I'm pointing to the pulley closest to the blade. It sometimes moves side to side when the motor is running. What can I do to correct this?

Is the blade also moving side to side, or is the pulley moving on the shaft? Your belt tension could also do that if too loose at startup. I use a 3" putty knife to keep herding water back to the drain holes on mine.

I just got my saw out and noticed that your table holdown screw is missing. This is the cause of the problem as it also keeps the bearing secured.

Sounds like problem solved with missing screw. Don't overfill sump also. Just cover cutting rim of blade. Most coolant will return through slot.

I thought someone was being a jackass and had drilled a hole there thinking about returning the water. Makes sense to have a screw there. What kind of screw do I need to buy to replace there?

Yeah I made the mistake of over filling it before I did my research on trim blades in general. My whole room got sprayed. Luckily it was quite comical. I still need to level out the saw I think.

Like yours, the original screw was missing. I tried one I had laying around, but ended up stripping the hole. Now after filling hole w/ JB weld using extra hardener, I drilled and retapped hole to #10-24NC, so that's the screw I use now. The screw is very short, less than 1/2" long, otherwise it sits above the table. I was only able to find a phillips version of this screw, I slotted head would be better so as not to catch rock crumbs in the head. Avoid overtightening. On a different topic, is there a splash shield on your saw at the front of the table? If not, adding one will reduce water spray on you.

The screw in mine is 3/8" long [10-24 thd.], and distance from table top to the bearing shell is 7/16". Does the screw actually hold the bearing too? There are no marks on the bearing shell, and I have no idea if the screw is original. My shaft/bearing assy. is tight in it's bore.

Looks like your good to go again...It is a good idea to do a walk through and look at your machine before you do any cutting,tumbling and etc..Sometimes things do come loose and unleveled..DPM,"daily preventive maintenance"....Army drilled that into my head..LOL

Still haven't gotten the screw. I have a small hex one that I'll use as reference when I go to home depot

QuailRiverThanks for the suggestion on drilling holes in the table! Not sure why I never thought of that before. I drilled 6 in mine last week. It made a world of difference! Roger

I used the bolt that holds the blade guard on as a reference and it was a #10-24. After find the hardware that I needed I felt my table needed a paint job. I also cut some sheet metal and screwed Into the holes that once held a spray guard. Here's what I came up with: I'm going to use some blue painters tape to keep the spray guard edges from cutting me when using the saw.

A huge THANK YOU to everyone that helped!!!!!!! Even though the instructions said this blade (brand new) was pre sharpened, I decided to let my first cut be some obsidian. No spray, no jittery blade, and finally no pooling of the water on the table surface! Hooray Ii finally have a working trim saw. Before anyone asks, yes I mixed up 2oz of Kool Lube with 20oz water and put some in the well. Ran a couple small geodes through the blade and those came out really well too.

I think you might want to use a flat head screw on the table top, otherwise it will interfere with larger rock.
