Turning a 135mm axle into a 130 mm axle
So I've decided to try and build a set of wheels from the hub up. I decided to use some 90's Deore DX hubs I had laying around. I want to lace them to 700c rims. I also want to use them in a road frame with an 8 speed cassette. The rear hub, being from a mountain bike is 135mm spacing. The frame I plan to put them in was spaced at 126mm and cold-set to 130. There is a 5mm spacer on the non drive side of the hubs axle. Can I just remove this spacer, shorten the part of the axle that would stick past the drop out and dish the wheel accordingly when building it? Does that make sense?
Thanks
Thanks

I had an extra lock nut, flipped it around backwards where I wanted to cut, and ground flat to it.
It sounds like you have a steel frame, so you probably need to cut the axle.
If you're running an aluminum or CF frame, you might be able to merely re-space the lock nuts to center the axle.
Or you could do as was done on the bike I just bought
Move all those washers to the left, and you get 126mm, I think.
Move them right, and you get 130mm.
And, add a few more, and one gets 135mm
The wheel has a bit of a wobble, but I think it had 135mm dishing.

A Dremel tool with a cutting disc will make quick work of an axle. Or a decent hack saw.
Measure before you cut! It's possible your Deore DX hub is already spaced at 130mm. I have some 7-speed Deore DX hubs in the basement and they're 130mm if I remember correctly.

A lathe will also do a nice job of it.
That would be my tool of choice.
Good to have tools.

Would first make sure that the Deore DX hub can take an 8 speed cassette (there were very early 90's, gone by 1992), as these were pre 8 speed, and may not accept it, would also check the retro value of keeping/selling the hubs uutouched, and just getting some current hubs that are 130mm, as older parts have a value if un-modified.

Good point about being 7 speed!

I had a '92 or '93 (not sure which as I bough it in '93 and it may have been a left-over) Trek 7000 MTB that came with Deore LX components and the rear hub was 135 mm but 7-speed.

Many of the Shimano freehubs are interchangeable. But, getting the right hub/freehub combo would be the first step before modifying the axle.

I thread a nut onto the axle past where I plan to cut. After cutting unscrewing the nut will clean up the threads.

And a file will clean up any "rags" left.
Just keep the file EXACTLY perpendicular to the axis. Trying to file a "bevel" just messes up threads.

Thinking back, your right, 1993 was the last year for DX, STX came out in 1994 and replaced the DX line.

The hub was originally 7 speed but I have already swapped the freehub body for a later one that will take an 8/9 speed cassette. I have a hack saw and dremel so cutting it down won't be a problem. I've also checked what they are selling for, and I really doubt I could get a set of hubs that are as good as these or that I like for what I'd make from them. Thanks for all the replies.
Does anyone happen to have specs on these hubs? I mean like the measurements I need when selecting spokes. While I'm at it, anyone got a recomendation for a cheap 700c rim to use while trying to learn to build?

The one I always see as a cheap but straight 700c rim (and the ones I'm going to use to build my next wheelset - never used before but others highly recommended) is the Sun CR-18 rim. If you look around a bit (Niagara Cycle sometimes is a good deal) you can get one shipped to you for less than $30. Then calling Dans Comp for Sapim Race spokes at $0.40 per spoke and nipple, is a good deal as well.

Keep in mind, adding the 8 speed body adds about 3-4mm to that side.
That means you have to shift your CTF dimensions by 1/2 that.
Subtracting 5mm from the NDS means you have to shift it 2.5mm more.
All for the "worse" regarding NDS/DS spoke tension ratios.
By the time all that is done, you may have very unfavorable ratios??
It might be much simpler to do something like this-

HB-M650 is the hub. With the freehub body swapped and the axle spaced at 130mm the hub flanges fall in line with other wheels I have laying around that are built so I think the DS NDS will be fine. What is CTF?

Center to flange.
An HB-M650 would be a FRONT hub!
I assume you mean an FH-650
[TABLE]
[TR]
[TD="width: 285"]FH-M650 135MM 7-SPEED REAR LEFT
CTF Left 32.50mm
CTF Right 21.50
After your mods-
CTF Left 37.00mm
CTF Right 17.00
NDS spoke tension is 46% of DS tension.
Better be looking for an OC rim.
