Micro-Mark HO & On30 Truck Tuner – Model Train Wheel & Axle Alignment Tool for Smooth Rolling Performance

Must have for the scale railroader. Works great on all plastic HO scale freight trucks. I will admit, it’s very difficult to use. It’s very fiddely and you will need a pick or knife to pry the trucks to get it in. Once it’s in, it works great. Make sure to blow out the shavings when you’re done. Great product. Must have.

I used this on a set of old time passenger cars by Bachmann. The cars rolled so poorly that the 440 engine that came with the set could hardly pull them. After using this tool they finally roll well enough to run on my track. I think this is a very good tool that works. I plan on using it on the rest of my rolling stock.

Not all trucks and wheels are made the same. When a wheel set can not be put into a truck, as in replacing plastic with metal, this tool can ream out the cone shaped hole to fit the new wheels.

Does the job.

The produce came very quickly to my home and the tool is very useful getting the car trucks wheels to rock and roll on the tracks. Thanks very much!

This item is for boring a correct hole size on an HO scale truck for axels. It only bores one side at a time, NOT BOTH. There is a rubber thumb-wheel in the middle, which might cause interference with parts of a truck, especially if it is a KaDee extended coupler. Do not consider this a "toy" but a "tool" to properly modify a "toy," or more appropriately, a "model" train.

This was for my HO Trains.

Works great for Tyco boxcars. Remove wheels, insert cutter, turn and then do the opposite side. I removed the rubber piece to turn it and use needle nosed pliers to turn it. Works great!!!!
