Considering what is there and the machine/setup time to make these...between $20 and $30 is a remarkable price....
your Dremel won't make sure the hole is centered...that's what the unique benefit of this device is...if it was just about putting the hole in...then you'd be correct..

I plucked this info from our resident "cavity king":
The cavity in the brush creates more "edges"... like serrations do. I guess
power is transferred better when there are sharp edges and stuff. The cool
thing about a cavity is it also decreases friction between the brush and
comm. It's really cool... when your serrations go away... you can cavity the
brush and it basically feels like you have serrations again. I've usually
noticed more power... USUALLY is a very key word there when I use a cavity.
hope that helped some?

.... my smart a$$ answer was going to be: it makes the brush lighter.

Are you making these yourself on manual machines?

Oh you guys tease about my crummy website. I am spending too much time building and testing to work on a website... and yet it needs to be done. I need help on it as I know nothing about websites. I know what I want and need, but it's a matter of making it happen. The guy who set up the first one is swamped. He's a good guy and I am hoping to work with him again. But I may have to make some changes for my behalf.
The jigs are being out sourced. The drill handles are done at my shop. It was the best eccomonic choice I could make. If they really take off, then I will out source everything.
It's been kind of interesting at the shop lately. Today, I worked on a large batch of bumpers that arrived in the nick of time. I was down to my last one in stock! Yesterday, I built up a bunch of drill handles and mated the bits while waiting for the arrival of the brush jigs. A new batch of stickers are on the way. I will have logo stickers go with the products... something I should have done long ago. The past 3 weeks have seen some intensive testing on a new t-bar part that will enhance rear grip. Last Wed, I was real happy with the results so that is off a production shop. I am real excited about this part. If you are on a non-Paragon track, this will be a must have. Best of all, it wont be expensive. A couple of weeks ago, I brought hollow carbon roll over antennas to market. That was a bit of a surprise market mentioned to me by Robert at Ashford Hobby. I have tested them with Spektrum and conventional 27 & 75 without any issues. I do recommend them for carpet, we were able to ruin a few of them on the asphalt. I just released a 3rd version of the popular diff thrust kit. I know have kits for 10th scale, Niftech and of course, the common 12th scale. My MS2.3 sales are slow, but come on... who can compete with Frank's Gen X car right now? I want one of his cars!
My new shop is small, but being heavily used for only being 3 months old. I promice to have some fun things seeping out the doors in the future.

Hey Cavity Fans,
I just received my first batch of brush drill jigs and mowed through the first 40 of them. I have only few left in stock. I did ship some to Ashford Hobby so you can check with Robert. Otherwise, shoot me a PM or email and we can get it out before the Holiday. The next batch should be around New Years.

the drill bits are not a snug fit in the jig so getting hole dead centre is hit & miss affair
But thats all
