Any recommendations for hinge pin reamers?

Right now I'm running a Slash, B44, and 1/8th scale buggies. I would think that a Hudy 3.0mm and 4.0mm reamer should be the right sizes for those cars.

Thanks. Thats a much better price.

So the Slash and B44 are both 3.0mm right?

Drill bits are far superior!! You can find cheap
kits of just about any size @ harbor freight

Tried that. Made too much play despite useing a bit the same size as my pins.

need something less aggressive.

You best bet is to go to a tool supply company. Get yourself HSS Chucking Straight Flute Reamer. They will run you around $10 each, but you can get them in the exact pin size within +.0002" tolerances and they sell them in .001" increments. I have a full set of 10 for my B4 and T4 are from .120"-.130" so I can match what my hinge pins are as they wear. HSS Jobber lenght drills or if you want some 6" aircraft extension drills also work, but I recommend Jobber because they have longer flutes then AE drills.

Edit: forgot to mention that if you go that route, don't get cheap chinese tools. Get OSG Tap & Die(one of my favorites) or any other American tool, they last longer and hold there size better.

Harbor Freight drills are not very precision to start with, and any bends or movement will cause the flutes to open up the hole that you just drilled.

removin material is never a good thing.

Instead u might prefer taking a heat gun, heating your hingepin, kingpin etc, gettin it very nice and warm and then sliding it into the arm/knuckle/carrier etc and let cool. the plastic will cool down faster than the pin, so it will stretch a very fractional amt and free the plastic up.

Kyosho makes cool 3.05 and 4.05 mm reamers kinda spendy but cool as hell, I still use an old racers edge from back in the early 90's for my electric stuff, I think those are still available. The tool and die post is solid as well, good luck

1/10 scale 3.0mm 1/8 scale 4.0mm and yes I highly recommend the proper tools for the job. Arm reamers are a definite in the tool box if you race. You have more control over a arm reamer then you have with a drill and heating parts and forcing things? Well thats just crazy talk

I've never had a problem with a DeWalt drill you
have to measure it with a pair of digital calipers to
ensure you are getting the exact size you need.
I'd say this was a user error on your part
you don't wana do this unless you happen to have a set of 100 drill
bits as I have down the the exact mm I want
you should do it big enough for the part to move freely
but not to much that there is actual play in any direction.

**cough titanium drill bits are accurate, and if you over heat your part
your DRILLING TO LONG and slow, if you do not know what you
are doing you will have to stick to reamers but reamers and drill bits
both cut material

you need the one thats made to drill METAL and its hard
to find the set im talking about has every bit each going in small
increments my set has 100 bits titanium coated

say my hing pins are 3.16mm I would use a 3.18mm bit

Still say if you know what your doing and have a set of nice
titanium steel drilling bits, you can do a more precise job

some of my hinge pins where 3.15mm and I drilled to 3.18mm and it
was perfectly free with no side play in any direction
