Re: Axle tuner?

 

When I have trucks designed for pointed axles, I deepen/clean the axle holes with the MicroMart HO one. You just have to work on one side at a time, since the tool is too short (being designed for HO standard gauge). On the positive side - if you're careful - you can make the holes exactly the right depth so that the axles turn freely but without "slop" regardless of whether or not the truck width is completely uniform or if there has been shrinkage or other minor manufacturing irregularities. The angle of the cone-shaped blade is fine.

As long as "bajadezert" has designed starting holes that are accurately placed, this approach should work fine. Perhaps with the increasing use of 3D printing technology for trucks, an "axle tuner" should be produced for S scale.

Hello all,
? ? A few weeks ago I found a gentleman on eBay who was 3D printing buckeye three axle trucks in HO scale.? After seeing some of his other items were available for O scale I contacted him and asked if he could do the trucks in S scale.? He said he could do it if I sent him the measurements for a regular two axle S scale truck so he knew how big to increase his buckeye dimensions.? After using calibrated calipers from work I sent him the S scale dimensions from one of my trucks at home.? Last night he sent me a message through eBay that he was finally ready to start printing this weekend and asked if I had a 1/64th axle tuner.? I have never heard of such a tool.? Does anyone on the list know of an axle tuner or have one?? What does it do and where could I get one?? He sent me a photo of HO & On30 one. I'm hoping the this does not mean that I would have to drill my own axle holes.
?
? ? If anyone is interested his eBay user name is ? He has several other trucks, loads, detail parts, and even full cars that he 3D prints and seems willing to do S scale for at least trucks (wheels not included).? His buckeye truck are available in friction bearing or roller bearing.? When I get the ones that I ordered I can give the list a review of the quality.
