I'm thinking about buying a heavy duty 1" arbor where I could put three concave 6" carving wheels (1/4", 1/2", and 1") on one side and a sintered 60 and 200 6 x 1 1/2" on the other side. That's a lot of weight spinning fast. I was wondering which one would work best?? I'm tired of swapping wheels on the Genie and honestly those steel carving wheels seem to heavy for the Genie.
Thanks, Tim

Any good 1" arbor should be able to handle that setup. I'd only worry if the arbor shaft was less than 3/4". You've got to remember that your genie shaft is only 5/8". It's the wheel adapters that bring it up to 1". that handles the weight of 6 wheels and end disks if you have them mounted. Don

Make your own, and you get exactly what you want , and it's alot cheaper too. There's 2 members that can help you out with the shaft. (why does that sound dirty? )/ Dr Joe .

I like Covington's two piece housing arbors. They bolt together making belt or bearing changes easy. You can order the bare arbor and have longer shafts also. Their hoods/pans only fit single wheels though so you would need to make hoods and pans.

Thanks Joe but I'm to busy/lazy to make my own. I'd resort to duct tape to hold it together till a wheel flies off and brains me. Thanks Don, the 1" concave wheels are heavy, like 4+ lb's. With the other two carving wheels it's at least 8 lb's vs. maybe 3 lb's for three nova wheels. I don't have the sintered wheels yet but they look heavy. Yes the Genie can handle it but it doesn't like it. Makes me nervous turning it on and off due the the huge weight difference between the opposite sides. It sort of wobbles till it's up to speed. John, I like the Covington too, looks tough, but the 4 place unit only take's 8" wheels and is $$$ What about the Lortone? www.kingsleynorth.com/skshop/product.php?id=95448&catID=1054. It's a lot less expensive but has a 3/4" shaft.

I have it and like it. I think it would handle the weight. but that price does not include a motor.

I've got a good 1/2 motor setting here gathering dust. For a dedicated grinder I like that setup of the Lortone as cross contamination wouldn't be a issue. Do you use the water drip from the top? Is it a pain to clean the bottom pan?

yes & yes. I have a drip form an overhead bucket that I can place over whatever wheel.
but I risk cross-contamination because I also use spritzer underneah. I find all overhead systems do not wet the full width of 1.5" wheels well enough. Besides I like to work very wet. In this regard I like the 2 pan design of Covington's CabKIng, which I think had 1" arbor, but they do not seem to sell it without the wheels, which sucks if you already have them.
I have a drain line with ball valce on the pan into a 5 gal bucket. I can mostly empty it (except last 1/8" of liquid) and also flush by dumping in some clean water.
not perfect.

I find all overhead systems do not wet the full width of 1.5" wheels well enough. Besides I like to work very wet. I'm the same way. The best way I have seen to keep a wide wheel wet is to just clip a square of carpet from the front edge of the wheel's "roof", with the shag facing & resting against the wheel. The wheel spins into it after the overhead water drip, and the carpet spreads the water over the whole wheel surface. It also keeps down the splash on your shirt when you crank up the water... kinda like a mudflap on a semi. Unless you're talking about a gravity drip system, in which case it probably can't put out enough water to feed a wide wheel. I use a cheap pond pump with forced circulation so pressure isn't an issue.

Covington's 400 arbor will take up to 10" wheels.

Hi I am in the process of building another cab machine which will be heavy duty like you describe and will carry 4 - 8 x 3 expanding drums which will resin imregnated belts on for diamond paste. I am using a 1" shaft at 24" long, at the moment it's being machined with threads at each end and having the flanges made etc but should be here soon and hopefully the drums will arrive from the States this week and then assembly can begin, the fun part.
On my last machine I made I used ply wood for the base, back and top but this time I am going to use plastics HDPE and weld the joints, good learning process. Good luck with your project Dave
