I got my Rock Rascal arbor mounted today. I bolted it directly to my homemade workbench. I added some rubber matting underneath the arbor. All I need now is my wheels and some type of water cooling setup. I ordered a diamond wheel from rocklady1 and an expando drum from ebersole for the arbor. Not sure what to do for water supply yet. So, my now setup is as follows: 1.) Trim Saw from yard sale. 2.) New 6" diamond blade from superagates 3.) Dop Pot and wax from Steve 4.) Rock Rascal arbor from a show 5.) Diamond wheel from rocklady1 6.) Expando drum and belts from ebersole 7.) Homemade work bench - wood from home depot 8.) Diamond Pacific mini-sonic vib tumbler I'm almost ready to start cabbing again.

Water supply isn't too hard. You just need a fountain pump, a gang valve, clear tubing, a bucket to hold water, and clamps to hold the tubing where you need it.

I set up my wife's Raskel with an aluminium pot rivited to a bit of angle iron with a valve at the wheel. Here are a couple of photographs showing the Rascal. Woody

You should be able to install fittings on the two fittings right over the wheels. I usually use compression fittings. You can screw a 1/4" pipe x 1/4" compression fitting into a 3/8" hole if it isn't threaded. I use 90 degree angled needle valve fittings and use copper tubing connected at a compression tee and one line to a water supply. You'll need a Compression fittings come with a sleeve now that allows the use of plastic tubing. You can use plastic tubing and connect to a submersible pump.

I notice the rock rascal in the "upper" picture has the motor mounted on the "right side" with the pully to the left, and the bottom 2 pics has the motor mounted on the "left side" with the pully to the right, is the motor in the first pic mounted backwards, or does it revolve in the opposite direction from the one in the bottom 2 pics? What about flat laps, should they run clockwise, or counter-clockwise? Mine runs counterclockwise, is it wrong? I am a "leftie", so it seems to work fine for me! Chris

Flat lap direction shouldn't matter. Cabbers and saws turn toward operator. Most motors made in last 20 years or so will have a red and black plug in wire in electrical connection section. Reversing the two wires reverses the motor rotation. People not comfortable doing this mount motor to the side. I always reconnect to allow mounting the motor behind to save space.

The sticker on my motor says to reverse the wires for clockwise or counterclockwise rotation. For my setup, it doesn't matter if it's mounted to the left or right because the arbor pulley is directly in the center of the unit and the distance from the pulley to the left and right is exactly the same.
I got most of my water supply lines hooked up. I used compression fittings and plastic hoses designed for evaporate coolers. Got a fountain pump to supply water. Now all I need is some bigger hose for the drain and my water setup will be complete. I'll post pictures of it when I'm all done.
I just received my diamond wheel and expando wheel in the mail. One more trip to Ace Hardware and I should be ready to put some rocks to the wheels.
As for my trim saw, I'm still waiting on a 1/2 arbor bushing. I ordered the 5/8 inch size by mistake. I've got about 6 preforms attached to dop sticks just waiting to hit the wheels and can hear them yelling at me to hurry up....they want cut.

when i electrically wired my motor i was really spooked which wire goes on what post? I went with instinct and plugged it in it revved then i was throwing my screw driver at it to it see if it was grounded properly i was so proud of myself that it didn't electrocute me I was told later that it doesn't matter about wiring polarity on an alternating motor i knew that

It doesn't matter to the motor and it will run with the leads from cord either way. If terminals are labeled L-1 and L-2 the black wire generally goes on L-1 and white to L-2. Sometimes it will tell you "connect ungrounded lead to L-1 or terminal 1" or something to that effect. The white (neutral) is grounded back at the breaker panel. Always use a grounded cord and connect green wire to green ground screw. Always use a GFCI circuit or adapter.

I wasn't trying to "worry you" dscratch, I just know that "some" motors are NOt reversable, this I know because of my deep research into what motors were avaliable to me at what costs, in fact, the one I "now" have on my flat lap is not reversable, it spins in one direction, and one direction only. I have found many motors I tested that were not reversable to spin in different directions, depending on their intended application I guess, so it just occured to me that maybe I should mention it to you in case you got a nasty surprise when you went to fire it up for the first time after everything was hard mounted! Believe me, I've done some pretty stupid things while not paying attention to detail, it happens! I'm glad yours is reversable and no "nasties" occurred in your assembly, it's always nice when things just "work" the first time! When I had the other motor in my flat lap (it was not reversable) it was spinning "counter-clockwise", and after replacing it with a better motor that also was not reversable, I noticed it was spinning "clockwise" now, which at the time of assembly did not occur to me that the direction might be different in this motor, but it worked out great, because I'm a lefty, so having it spin "away" from my hand is way better than having it spin "towards" the hand that is holding the dop stick. "Polarity" actually does not "exist" in an AC circuit (yeah, I know, it's both plus and minus...lol) but the orientation of your hot and netural wires "could" be important in certain circumstances, so if at all possible, always make sure your hot (black) and netural (white) wires are connected appropriately, this is the reason your house recepticals have one "fat" hole for the "fat" prong on your AC appliance plug, to insure it is actually oriented properly. There is a huge arguement about this subject, but I always like to just comply with the intended manufacturer recommendations! lol. Chris

Generally all switching is done with the "hot" line. My dear old dad could make anything work but following up on his work was a shocking experience. He would switch neutrals and run hot leads around switches and mix up polarities from one receptacle to the next. His lights all worked and motors all ran but it is always safer to do it right. An example is a light bulb. The threaded base is supposed to connect to the neutral. If you touch the base while unscrewing the bulb with the power on you will get shocked. If the neutral is switched instead of the hot lead especially. The light bulb doesn't care and will work fine but it is unsafe.

I checked the wiring before I tested the setup. As a network engineer, I do a lot of wiring. I've learned my lesson by trial and error. I appreciate the responses, I actually learned something from your responses.
I did get some of my water supply lines ran tonight. Now, I've got the submersible installed and the drain line ran. All is looking good so far, let's see what happens when I try to touch rocks to the wheels!

I have a bit of a problem with my little fountain pump in my water resivoir, it keeps wearing out the impeller because of all the "grit" that gets recirculated through it, so I'm going to have to add a "filter bag" to the return line, so it dumps the returned water into it, thus capturing any freeflowing grit or rock sediment that keeps fouling the pump, you may find a similar situation somewhere down the road too. Just thought I'd mention my current experience when it comes to water Take care, good luck! Chris

Best thing is to pump out of a clean water bucket and drain into a separate bucket. Why recirculate dirty, contaminated water and take a chance of contaminating your belts/wheels?

I plan to use the two bucket method. Pump from one and drain into another. Less chance to damage my fountain pump. Thanks for the tips.
