Soft Aluminum Bench Vice Jaws
Pretty
much the most useful single tool in a bike shop, home or pro, is a
bench vise. However most bench vices come with knurled steel jaws which
can easily damage a typical aluminum bike part that you may want to
clamp.
Traditionally, smooth jaw covers would be made up out of sheet
metal. But these move around and can fall off when used. Some vices
come with reversable steel jaws that are smooth on one side. But these
are still steel and can damage aluminum bike parts.
What
is needed for bicycle work is a set of smooth, soft aluminum jaws.
There are some commercial suppliers of these, but they use magnets or
some other device to hold the jaws in place.
I made up mine from
aluminum stock to fit my vice exactly and securely. Just use the
existing jaws as a pattern and cut two pieces of 1/8 inch thick
aluminum to fit. Drill and countersink the holes and bolt them up over
the existing jaws. Use screws 1/8 inch longer than the originals. Save
the original screws. Photo's below.



Now you can clamp that aluminum bike part, such as a caliper brake, and not worry about damaging it with knurled steel vice jaws. You'll want to use this set-up even for clamping steel parts such as freewheel extractors, no need to damage them either. I have even clamped threaded steel parts, such as axles, with no damage. If you have a project that requires the extra grip of the original knurled steel, just remove the aluminum jaws and reinstall the original screws.
About the Author: When I was about ten years old and had just received my first full-sized bicycle, my father presented me with an off-set 1/2 - 9/16 box wrench so I could adjust the saddle. It was all uphill from there. Since that single-speed, balloon-tyred Columbia passed from my hands, I have wrenched my way through three-speed hub Schwinns and English Racers, bike-boom tenspeeds, primative mountain bikes, and the modern stuff. I have purchased tools, modified tools, and made them from scratch. My raw materials are sheets of aluminum and wire coat hangers. Workarounds are my specialty.

That vise rocks! It has been in continuous use since it got drilled into the beat-up card table Harv mounted it on. I would go so far as to say that bike shop ain’t a bike shop until it has a vise.ubrayj02 (Email) (URL) - September 17 '06 - 22:45
One of my proudest moments with my bike was when I fixed up a little tool for myself while putting a chain back together (haven’t gotten that ambitious for years). I was propping the bike against my knees because I had nothing to mount it and was trying to relink the chain on the derailleur (I think that this is what I was doing, anyway), and the spring kept pulling it apart.BradyDale (Email) (URL) - September 19 '06 - 14:48
BradyDale, I use a piece of bent coat hanger wire for a similar purpose, but in a different way. I will put this “mini-tip” in a blog so I can include a photo. I call it the “fifth hand tool”. I will explain why in the blog.Harv (Email) - September 20 '06 - 11:37
these tips are great. BradyDale’s coat hanger trick sure beats my push the deraileur forward with my foot move while I push the rivet through the chain. And I can’t wait to read Harv’s take on it.Shay (Email) - September 20 '06 - 12:06
