can't you just turn the motor around to sit behind the saw - won't that make it turn the correct way?

Nope Diane, that would make the saw run backwards. I need to reverse the direction I have the saw running in the video so the nut on the arbor doesn't loosen up when it's running. So turning the saw around will solve both problems.

if you turn the motor around and put it behind it will change the direction !

I made a 10" saw out of 1/2" plexiglass for the tank and the table top. I cut 1" strips from 1/4" plexiglass and fastened those around the edges of the table top to keep the fluid in the saw. But like metal tops, after a while the blade slot takes a beating and you wind up with a wide slot in front of the blade and it digs into the plastic. You did good! Except putting the top on backwads!

I'm glad this helps, Charlie. Good luck on your repair. LOL Ed, I slapped my forehead when I got it running! The arbor direction never crossed my mind... Until I shut it off and the blade kept spinning after the arbor stopped. I bet it was cool seeing the saw running through that plexiglass! Got any pix of it? Nate

Yea, it was cool seeing the blade for about 30 seconds, I cut some boulder opal as my first cut! I might have some pics, let me check, if I do, I'll post them. Have you made a new top yet? The way these saws are set up, is the motor is behind the tank so the pulleys line up. You'll need to make sides for the new top so water won't run into the motor.

Right. Turn motor 180 degrees and put it behind the tank. You may need a longer belt. You may want two smaller pulleys to help clear the table.

Good idea John, I hadn't thought of smaller pulleys.
Ed, this afternoon I took the top off and flipped it over. It lines up nicely. I just need to counterbore the holes so the bolts mount flush and will be good to go. I'm thinking about getting another cutting board and cutting strips from it to try to solvent weld on the edges to keep the coolant in. I need to find out what type of plastic these cutting boards are, and if I can get the correct glue to solvent weld it.
I also want to see if the frame/stand I had built for my tile saw will work for this saw. I'm sure it will with a little modification. Then I'll be able to mount the motor under the saw so it's a smaller package and the motor weight will keep the belt tight. I'll just need to be sure to put a drip pan under the saw so it keeps the motor dry.

turning the motor and putting it behind or under does change the direction so......I was right

I am sure it is HDPE - High-density polyethylene. Not a product that likes to be glued to itself or to other materials. 3M has come up with a product that is suppose to work. www.rshughes.com/products/021200_30088.html?ref=m&refcp=catalog&mr:trackingCode=1E63DD2E-7753-E111-B136-001B21BCB944&mr:referralID=NAYou may find it easier to use angled corner trim and screw it to the top from underneath using a bead of silicone as a sealant(not as a adhesive). if you cut a triangle out of one flange of the angle corner trim you can bend it at each corner to make the rectangle. Cut a square off of one end of one flange to make a tab that can be connected to the other end where to two ends meet. - make sense? I can provide a pic if you go this direction but need a visual of what I am talking about. Love the use of ordinary to achieve extraordinary! Steve

After taking an old HP saw apart today I see your problem The pulley goes on the left side (facuing from front. Turn the saw around and mount motor behind as is and direction will be right. You will have to turn the table 180 degrees too. Your saw is different from mine. Mine has the arbor and shaft mounted (actually casted into it) to table bottom. Mine is a very pale green that looks like it could be original as it is flaking off and only showing bare aluminum under. Anyway, facing from front pulley on left, vise/carriage is on the right.

That's correct John, and exactly as I tried to say before lol. I'm not too good at explaining things sometimes.

I was thinking you had pulley on correct side and couldn't understand moving the motor behind. Were you able to reverse the top? Mine has 4 screws holding top down but I didn't notice if it is symmetrical.

Yes, the top still works. I was able to just flip it over, and the bolt holes still line up. Maybe I'll be a ble to work on this again this weekend.

Well, I got the saw almost done. (finally - it's only been 2 + months : It just needs a belt guard and a splash guard in the front to keep the water off me. Here's a quick video of it running w/ water in it. The blade guard works great! I pulled the motor and saw off the plywood and will put a few coats of poly on it tomorrow to waterproof it. It's much quieter than my WF saw. I love it already! Nate

Thanks Pat. It was a very inexpensive retrofit.
I forgot to mention since I took the pix I drilled holes along the blade slot. I wanted to cut something first so I knew where the water ran so I knew where to drill. I may also route a groove along the perimeter of the saw top and back to the blade slot to catch any water that escapes the holes.

What is a belt guard? Just kidding. None of my old saws ever had belt guards. Your belt looks a little loose, too.
