Ok, I've got one WIRL race under my belt and now I want to try my hand at a modified car. I'm sure this has already been covered but I'm going to ask anyway. What do you guys use to drill the needle axle holes? Drill press, pin vise? I thought about getting a drill press for my dremel tool but I believe that the dremel spins way to fast for a 1/32 drill bit. Thought about a pin vise(readily available because I'm a tool dealer) but what would you use to ensure your hole was acurate with a pin vise. I don't have a small drill press but may have to invest in one. What do you guys use?
thanks

Ditto:
I have my first set of needles and RSN Wheels and I have the same question as to the best way to drill holes.
DD provided me instructions during March Wirl race but can find them now...
Thanks!

This is definitely a delicate job. I'm no expert but what I have seen is that a pin vice, very slowly, is the preferred technique by experts. It's easy to break the bit off in the body- be careful! There really isn't any sort of guide to assure alignment (like the pro-body tool for big axles) but the needles tend to be a little more forgiving and are a lot easier to bend. I've heard of some using drill presses on VERY slow speed. I've also chucked the pin vice in a hand drill after piloting the hole with a scrap pin. Good luck with it- it's definitely one of the more difficult steps- that's why you don't see that many needle mod's. I think that a lot of builders (non league that is) aren't up to the challenge.
But that's why we race here right? ;D

Hey guys, there is a company that makes a tubing with a 3/32OD and 1/32ID. Not sure if it would work but it would be worth a try to install some in the probody tool and see if it will bush it down well enough.
C-FLEX Tubing
EW-06424-60 C-FLEX ® tubing, 1/32"ID x 3/32"OD, 25 ft/pack $16.74 (CND- import fees included)
Available in 5 days.
It sounds like it may be worth a try, and at that price someone could make several hundred bushings.

Ironically I received a call from Racer-X a few days ago and he had me try the same thing !! He actually had me take the straw from a WD-40 can and insert it into the Pro-Body Tool (it's a perfect fit) and cut it down. The drill bit that is supplied with the RSN and SSN wheels fits right into the straw !! I was drilling perfect needle axle holes with my pine-vise in no time !! You could actually purchase an extra Pro-Body tool and lightly glue the inserts in or just leave them loose and use it to drill both types of axle holes !!

Yep, it's out now!!! ;D ;D ;D ;D ;D COME ONE COME ALL AND GET YOUR FREE PRO BODY NEEDLE TOOL!!!!  The red straw from a standard WD-40 can dose a nice job for needle axles, you can do all 3 holes and have the raised wheel as well. The fit is not bad for the price of admission and all you have to do is take the bushings out and it is a standard axle tool. We have been working on a needle only tool but it is just difficult to make in a production world and be reasonably priced. Race Fast Racer X |

Not only do the straws make good bushings for drilling needle holes, they make decent bushings for converting ss wheels to needles. They fit pretty good for non lathe bushings. If the bore seems too big you can tighten the fit by wrapping a small piece of teflon tape (used to wrap threads) around the bushing. Need to warn you, it can be slow especially if you have short big fingers like yours truly. I have also used them in 1 gram bsa wheels. Just as a side note, I have only used them with graphite since it's more forgiving than oil. I'm not sure the bore of straw is good enough to use oil.

Well, as long as everyone is "out" with their tips on drilling needle holes, I may as well confirm that what RacerX describes. It is true about the little red straw. It really works great.  Something that I discovered in the process: I chucked my pin vice that was chucked with the needle drill bit in my hand drill with it chucked in a table vice ;D One hand on the trigger at VERY slow speed, the other hand on the car and probody tool grasped firmly- kept the drill stationary and moved the car to the drill. It drilled a faster and cleaner hole. I never had the patience for using a pin vice with my fingers- I've only built three pro-mods and probably broke 6 bits before discovering this method. Try it, you'll like it ;D BTW: I am pretty far from the best builder so take my advice with a grain of salt- but it worked ok for me  |
