Machining the Mean Streak = not much fun
« on: April 05, 2014, 06:03:04 pm »
Hey folks,

Does any COG'ers know of a machine shop in the Northeast that has done your or someone else's mean streak wheel machining?  I have found a few machine shops but they are quoting in the range of $170-$250 for the job.  Generally, they aren't too too sure about how to do it, etc.  They say it will be 2-3 hrs.

I was reading on the forum here about guys getting this out the door for $50, maybe thats a few years ago, but I'd like to get out of this for $100 or less.

Please, if you have the Mean Streak wheel and live within 200 miles of Washington DC, let me know where you got it done and how much you paid.

Also, do the bearings need to be out to do the cutting?

Thanks in advance for any replies.

The trick for me was finding someone that had a lathe with a large enough swing to spindle up the wheel with the bearings in. The guy that did it for me held the wheel from spinning with, of all things, a large bungee cord (years ago it would have been a leather strap). It was then just a matter of face turning off the .300". Took all of a half hour to do. Easy peasy. Guess it's who you know, because he did the job for a six pack of craft beer. $170 to $250 sounds high to me, based on the amount of work done, and the time to do it. But- I have ne idea what commercial machine shops charge per hour. Hope this helps.

Or, you could do what I did and not machine the wheel at all.  http://forum.cog-online.org/index.php/topic,47800.0.html

I got mine done for $85 two years ago.  The place that did mine specializes in repairing damaged expensive rims.  They did not have to remove the bearings.

They are, unfortunately, outside your requirement of within a 200 mile radius of DC.

Good luck.

Yep, that is the whole problem. An engine lathe (a conventional lathe) with a swing of 18" or more is a BIG lathe and tough to find. What is needed here is an old gap- bed lathe which is a lot smaller, strictly a manual machine but the ways do not go all the way to the headstock hence something large and relatively thin, such as a wheel, can mount to the headstock and not have to actually clear the ways diametrically. But they are pretty rare and usually quite old- I have only ever seen a couple in my entire life.

A horizontal boring lathe would work too and they are more common than a gap- bed lathe but they are so large that the machine time in them is usually expensive.

Best of luck finding a place.

It is also possible to do the job on a vertical or horizontal mill, but with many shops moving to CNC the cost goes up due to programming.  Your best bet is to find a more "old school" shop that doesn't need as much time for setup.  There may also be a wheel shop in the area that would probably be able to do it.

As txfatboy states there are alternatives to machining the wheel.  I used the Mean Streak rotor on an unmachined wheel, but I made my own brake caliper bracket.  Not machining the wheel may result in the side bags contacting the caliper, causing it to drag, so if you go that route you'll need to make sure you have adequate clearance.  I have aftermarket bags with plenty of clearance, so that wasn't an issue for me.

Beej,
it ran me $150 up here in the Northwest.  hard to find a machine shop that would even do it.  most were scared of liability when working on vehicle stuff.  I called a dozen places and finally I found 1 place that would do it.  ran $150,  I showed then the article from the tech pages.  on the positive side, the guy that did the machining also taped the rotor holes deeper by the same amount he milled off of the rotor mounting face, which we never discusses as I figured I could do that myself.  thoughtful guy. 

as far as relocating the caliper etc for the no wheel machining approach, in the long run if you have to get welding done etc. and you can't DIY it may end up running about the same $.  6 of one, 1/2 dozen of the other as they say.

if I had to do it over and had the two choices, I'd still get the meanstreak wheel machined.  and though the machinist never mentioned either way, I went ahead and took the wheel bearings out of it since I was going to replace them anyway.

Mine was done on a big vertical mill with a rotary table.  Cost me $160 here in SoCal.  My guy didn't care if the bearings were in or out, and I replaced them anyway.  The hardest part was finding a shop that would/could do it.  Most places now are CNC production shops.

Cost me $225, but I am in a small town with one machine shop. Three hours on cnc mill. Painful, but the final product is worth it.

I'm in Charlotte.  It cost me 150.  The 170 price is nit really bad given the setup that has to be done.  If you can find someone who has already done one you can save some of the setup cost.  Good luck with the search.  You'll love it the long run.   :beerchug:

All,
I have a friend who is willing to machine these wheels. If you are semi-near the metro Wash DC area and need a wheel machined let me know. I believe he will do as many as I give him for @50$ each. He has a full machine shop at home. He was an engineer for Chrysler Corp in the '70's.  He is currently setting up a 30" swing lathe on 144" centers!  The old 17"  100"  just wasn't getting it done apparently.

Actually, the Meanstreak caliper bracket puts the rear caliper in the natural recess of the stock saddle bag. There is no clearance issue with this setup.

txfatboy, glad to hear you don't have a clearance issue, thanks for the input.  Even so, some bags droop more than others and the stock caliper that I used is different than the Mean Streak caliper as well as being in a different position.  Just wanted to make sure that anyone wanting to go that route checks their clearance.   :great:

I am delivering my MS wheel to Matt today for the $50 special!  Hopefully his engineer pal will be up to the job once he gets his hands on the wheel.

If your paying $150+ to have it machined, how come you don't just order a new one that doesn't need machining? Murphs has them for $185.

I am not aware of anything Murph has to use instead of a meanstreak rim, which needs machining to have the rotor alignment proper with the caliper.

Kurt, I think that's just an EBC rotor to fit the wheel. I believe the wheel must still be machined to position the rotor properly.

yeah, not only that, but the meanstreak wheel has a 7 bolt pattern, not 6.  you need to either machine down the meanstreak rotor to the correct circumference, or get a front rotor from an older Nomad (or order an EBC one that will fit the Nomad).

Ok, missed that. I thought it was an either or.

So you have to machine down the wheel and machine the stock rotor or buy the front Nomad (or equivalent).

As long as it is a dull hammer and a sharp chisel all should be good!   :-\ ;)

Mine was done locally at a small old shop. Cost me $150 including cutting down the stock mean streak rear rotor to the 280mm size.  However I ended up not using the cut down rotor so it was a waste of time and money on my part.
