Quicky tut on using pen tips to mount alloys
Posted: Sat Aug 23, 2003 9:36 am
At first I was leary of reccomending my pen tip method, because my wife used to collect advertising pens and gave up, so I had to sort through literally hundreds of pens to find the right tips. Didn't seem like the most practical way of going about it.
But now I've found a brand of fairly cheap pens that'll work, and I think this is a good method, because my rims spin 100% true, and metal wont wear as fast as epoxy or other filler.
The batteries are dead in my camera, but I think it's simple enough we can do without pictures. Here's what you do:
Get some Pentel RSVP medium tip pens. I got a 3 pack for a buck and eighteen cents.
Rip the tip out, use a pin or needle to push most the ink out. Soak ithem in alcohol, or nail polish remover to get the rest out. Twist up the end of a paper towel and clean wipe out the moisture.
Now your ready to cut them down. You can use a Dremel w/ the red cut off wheels, or a razor saw. Use a pair of vice grips, gripped very tightly on the section you not going to use.
Your gonna want to cut them as shown in this diagram:

You'll be using the narrow section of the pen tip.
You want to leave a slight lip on the front ones so the head of the pin doesn't pull throught the wheels. Slip it in your alloy mount it up.
The back is trickier. After you've got the rims off the back axle, and sanded the lip off the gear, put the gear back on the axle. The pen tips are snug so you'll have to pound them on with a hammer. Be very careful not to bend the axle, or split the pent tip bushing, and checking against your chassis to make sure they are not pounded on too far. The bushing just slips right in the rear rims, and you'll have to glue them.
And your done, it's just that simple, not counting pen tips flying across the room, splitting, or other unaccountable miseries, but I've done this on both 10mm, and 8.3mm rims, and worked out great.
