One other thing to remember, I have never seen a 500+ pound dirt bike.

how about this guy

I have read some polar thoughts on this since i first posted this, I have drilled the cover which actually made a noticeable difference in weight, but the Idea of the brake surface was more from a kinetic weight stand point. I figure even if it is only a couple of ounces, that weight put in motion will become magnified, and so will the effect of taking weight off. That from what I can figure would only be a secondary benefit. The primary would be cooling and allowing the gas that builds b/t the shoe and surface to dissipate and thereby improving braking.

My bike will be fair weather only, and will see limited use. I am still pretty early on in my project and am mocking it up at this point, and also kicking around some Ideas. I still haven't gotten a shop manual yet mostly b/c I haven't needed it, but that time is coming quick. What sort of wall thickness should I be looking for on the drum surface (74 cb550) as that will certainly spur the search for a new assembly if mine is not adequate?

I doubt that scrambler from victory is 500 pounds plus it is not a dirt bike, maybe a possible enduro. it looks like the old honda 360s

The cast iron drum is actualy cast into the alloy hub, or the other way round, and the 500/550 is renowned for cracking as i have said before. New hubs do sometimes crop up but cost £250 ($400ish). I have had a couple machined out and new cast liners shrunk in under pain of "NO RACING" from the machinist! If you look in the drum there is a maximum diameter it can be machined to,181mm from memory BUT CHECK THAT,

probably not 500 lbs, but cool none the less

Cycle Xchange outta Packer land (Wisconsin) does a drilled rotor 4 stocker exchange program...

From the pictures, the work looks like it is done well. It sounds like he has experience in the trade and has the right equipment for the job. I have found a guy who will do the same thing for $75 per rotor (surfacing and drilling).

angeldeville · « **Reply #84 on:** October 31, 2006, 07:34:41 AM »

the work looks good, I'm looking to do this myself on a few of my bikes, it might be worth my while to get one or two from him so I can see how he did it. it would be too 'spensive for me to hav4 him do all of mine.

Hey Tom, You got 2 fronts and a rear ready to exchange? Are you surfacing too?
Check your email. Robert

They do get a mild resurface. There was never a lot to re cut on the rotors. I do not have them for exchange right now but they can all be drilled in one night and back in the mail in the morning provided the payment goes smooth.

They are first mic'ed and then turned if needed. Mostly they are just turned with a non-directional pattern and then crossdrilled.

Explain turned with a non directional pattern

scunny · « **Reply #92 on:** November 01, 2006, 12:56:55 AM »

non directional sounds like me on the trusty pub bike after a couple of beers

anubiscycle · « **Reply #93 on:** November 01, 2006, 06:00:56 AM »

"Non-directional" Is a nice way to say swirl pattern. Like the last kit we did. This keeps the pads from having rotor crawl. If they were just machined the pads can crawl up and down putting excessive force on the braking assembly as well as decrease braking efficiency.

So what does one do to have this service provided?

So what does one do to have this service provided?

First contact me at 608-415-1401 to make sure that there is an opening (this will change as work load changes and I can give you a lead time). Right now it is 1 day. This will change I am sure.

1. Pack your rotor(s) into a priority flat rate box - they are cheaper (these are available at your local post office). Please include all contact information. A phone number is always helpful if there are any issues. If you intend to pay by M.O. please make sure it is enclosed in the box for the machining at $20 per rotor plus the $8.50 for return shipping. If you will be paying via paypal, please wait for a invoice from us. IF YOU HAVE A PREFERENCE TO DRILL PATTERN - YOU MUST INCLUDE THIS IN YOU PACKAGE.

2. Ship your parts at your local USPS office (please make sure you track your part) to us at (this is the house addy so nothing gets goofed):

Anubis Cycle LLC
517 N Park
Reedsburg, WI,
53959
USA

3. When we get your rotors, we will send you an email or phone call if needed to let you know when they are recieved.
4. Your rotors are machined and cross drilled in house if we do not have any exchanges. This will not delay your order normally.
5. They are return shipped via USPS to you. We will track your part, but will not send an email with the number unless there is a problem. The logistics of this are just crazy so for now this is how it is done. If there is an issue we can and will provide your number.

The total turn around right now is about 5-7 days 3-4 of these are shipping.

I'm going to be doing a GL1000 front end swap on my 750, its a dumb question, but you'll be able to do those as well, right?

We can vent any rotors you have. Not a problem.

mrbreeze · « **Reply #98 on:** November 01, 2006, 12:48:09 PM »

I know what a non directional finish is. I probably do 20 auto brake jobs a week. I just didn't understand turning with a non directional pattern. So you have a bake lathe that you "machine" the rotor with.Then you take a die grinder with an abrasive pad and apply the finish? Or you don't have the lathe and you just buff the rotor and drill it? I don't follow.

Ernie · « **Reply #99 on:** November 01, 2006, 01:34:59 PM »

no offence tom but those rotors look like they were done with a palm sander or somthing ,do you use a lathe or surface grinder at all?
