Drill Rotors - Los Angeles

Does anyone know a place that will drill holes in my rotor in Los Angeles? I would do it but only have hand drills and don't want it to get sloppy, if I had a press...different story ha. I did find truedisk.net and may go that route but would prefer to avoid shipping back and forth and downtime on the bike!

Any advice would be great! 74' CB360!

A drill press is only about $130 Canadian. It ought to be even cheaper from harbour freight in the USA.

Yeah, I can get one for $50 bones, just trying not to have more things laying around and I don't see myself using this often which is why I prefer to just pay someone to do it instead. But if I can't find anyone I am going to grab one at Harbor Freight!
 
Oh man I dont know about you but I use mine all the time. So much easier to drill proper holes in plates for all my projects. Also super handy to sand and polish. Stick a sanding wheel or small buffing wheel in there, set to highest speed, and it's awesome.

I use my cheap press for polishing, wire wheel, occasionally even for drilling. Watch Craigslist and Marketplace and you might find a used one. Get one with belt drive and you get a lot of speed control with the different pully sizes.

You probably know this anyway but the hole diameters should be less than the thickness of the rotor, this way the surface area is increased. My GT750 rotors have 3/8" holes (old school) and while they look cool, the surface areas have been decreased, this was common back in the day and I did that to my H2 rotor.

Convincing me more and more haha

I didn't even think about polishing and such, I guess there are more uses for it than I though. May just pick one up today and do the thing

This is actually good info, I have been looking at a few designs that people have done and am creating a template to print out and use!

Drilling OEM stainless rotors that have been through a heat cycle can be a real bitch. Buy a bunch of cobalt drill bits, use alot of cutting oil and go slow.

I've never done it myself but I have read, I think on DTT that the rotors are very hard and you go through a number of bits doing this.

Yeah I have read this as well, I am waiting on the guy from truedisk to get back to me, honestly if he will do it for 45 bones and I can ship it to him I'd rather go that route. This is more for asthetic anyway, it doesn't ever rain in Socal so it's really just to give it more of a sporty look

For that kind of money I would just pay the machinist, they won't screw it up and you can work on something else in the meantime.
Yeah kind of what I am thinking, I will await his response! But if anyone knows someone in LA, please let me know, would love to not have that much downtime on the bike!
