Howdy everyone, I am hoping this will be a breeze for experts I have found here in this forum, this is my latest acquisition, a good size rock/slab saw... If you can make it out, it has an interior vise/clamp for the rock on a threaded rod which is connected to a 3 step pulley with a small belt going to a (looks like) hand made motor. Next, a 24" blade that just touches the oil held in the drum. The blades' edge is not rough, but looks a lot like a continuous weld. It is attached to an exterior pulley that measures 9" across center. Unfortunately there was no exterior motor and the person I got it from knows nothing about it other than the previous owner skipped town owing them money and back rent. This was the last piece they was selling (all the other tools had been sold and the new renters needed to move in) I got it for $10.

Any idea on what size and type of motor I need and what blade works well with something this size?

Cool Saw!!! I am guessing that it is a Mojave Industries, I had a 14" one that had a lot of the same parts on it. As far as a motor, I would use a 1HP 1725 RPM.
Awesome score.

Cool find! The motor on front is not homemade a lot of the older saws had that style motor for the power feed.

Thanks for the tips: 1. Thanks for the suggestion, I will try and find one of theirs that matches up, also, what size pulley should be on the motor? 2. I do have some rocks, a geode , and some large ruby rough that I am just itching to get cutting on 3. lol, I called the little motor homemade because it just has a piece of sheet metal bent over covering it and it looks a lot like an old door bell motor Thanks again for the info

On my 24" saw, the arbor pulley is 10" and the motor pulley is 2 3/4". If you go to the diamondpacfic web page, they have a chart somewhere on there that tells you what the ideal rpm is for different saw blade sizes.
My 14" saw had the same exact motor and brackets for the the screw feed as your saw. You got the deal of a life time.

Definitely a 1hp 1735 RPM motor, preferrably with capacitor start and run. A 2 inch pulley would be fine with the type blade it has now, if you get a sintered blade later maybe switch to a 3 inch pulley. Because the sump is so small I would make sure the oil goes at least 1/2 inch up the blade.

My HP 24 had a 1-1/2 hp 1725 rpm. I wouldn't put a 1 hp if it was my saw. Better to have more power than needed. Like a friend of mine used to say back in my dirt bike days "you can drive a fast bike slow but a slow bike will only go slow". Speed charts are mostly for the old style notched rim blades. If you go with BD/MK blades follow their 303 recommendations. They run better a little faster. If you have a 24" continuous rim blade it may be a concrete blade. Even with a motor and blade you made out.

I will probably go with a 1735 rpm 1 1/2 hp motor, I will swing by the motor shop this weekend. Gonna spend my time and strip the whole thing down, address anything that pops up (or falls off) and put it back together and start slicing sweetness

I've seen Mohave saws up close..it's either that or an Ideal or someone built it modeling one. Also it was built from a kit. The Mohave's i've seen have had the rear angle notched out for the blade. They also had the nub grabber strips on the vise bookends like yours has. The motor on the front is a gearmotor and you can order them here: www.mcmaster.com/#electric-gearmotors/=rzmfxs
