Default 1/12 arbors

I just picked up a RDLOGICS 1/12 arbor:


When mounting the front wheel in this arbor, it only centers the wheel on one side. The other side just applies flat pressure.

The RC4LESS arbor seems to do the same thing:


Again, you'll notice the flanges are only on one side. Is this normal with all 1/12th arbors? Why in the world wouldn't they have flanges on both sides?

Default 1/12 Arbors

Hi Katana, the reason most arbors only have flanges on one side is that is all that is required. The flange is just to keep the wheel centered on the arbor. The tightening nut is to keep the wheel flush against the clamping half of the arbor, and the nut only should need to be snug tight. The 3 different step flanges on our arbor allow you to true both front & rear without switching arbors plus it will work for 1/10 pan car rears as well. The steps in the flanges are machined to fight tightly inside the bearing opening and the rear wheel opening. Machining a step on the tightening nut could be done but it would eliminate using the same arbor on both front and rear.

Hope this helps.

Thanks rc4less for your response.

dakrat, I figured that with both sides having flanges, it would be perfectly true. Whereas the current method is pressing flat on the spokes on one side of the wheel. This assumes that the spokes are flat.

does anyone know if the OFNA, Hudy and Integy 1/12 arbors are all interchangeable?
I've got an Integy Trackside truer and am wondering if the OFNA arbor will work okay, even though it says its specifically for the RC12L3, I figure it should work for any 1/12 tire, right?

It should work fine. The arbors for the truers you mentioned all have an 8mm shaft for the arbor to clamp to and they should fit the current crop of 1/12 wheels. Now if you are using the old 2 hole rear wheels they probably won't fit.
