I have been doing some maching for a local bike shop, and the guy wants me to start drilling the occasional rotor.   I would do it if I had a quality rotary table for the mill, otherwise the layout time involved would be high and the the more complicated patterns would be damn near impossible. 

I know we are unusually cheap and DIY on this board, but what would be a reasonable price for a sohc4 drilled rotor?

Depending on the pattern, between $10.00 ~$40.00 per disc. Most people photoshop something they like and scale it to the rotor size. print it out, stick on disc and centre pop the dots. Then just drill it with a pillar drill (Drill press). Its actually better if things are not completely symmetrical as you dont get resonant vibraions set up (take a look at early/mid eighties Kawasaki's)

I was gonna say about $40 - $50 per rotor, if that. Dragman did mine on his drill-press in his basement, and came out great. I actually plan to get another set of rotors and make up my own design, basically so I can use the new drill-press I just bought  ;D

Buy yourself a good Heavy Duty drill press from the Depot and save the cash...

Charge no less than $50 per hour. And this is the bottom of the line machine shop. I would expect to pay about $35 - $45 each rotor for ones that are done perfect. Plus a set up fee for anything that is not the normal pattern.

  • So, what do ya wanna talk about today?
True story Daniel, I've got a mill and rotary table that I use when machining my oil cooler adapters, but I wouldn't bother doing discs for money, the time that it'd take to drill a set of discs properly would cost more than some people pay for their old bikes.

The pillar drill and scanned/printed pattern is probably the most economical, but I've seen some shocking jobs over the years, and one or two cracked discs due to people "swiss cheesing" their discs with insufficient metal between the holes, so be careful peoples, the life you save, might just be your own! Cheers, Terry. ;D
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"
