I finally got to use the cutoff saw I got from Micro-Mark a few months ago.
I cut the tubing I'm going to use to make the axle for the front wheel. The kit comes with an axle(the black piece in the third pic) but I decided to use tubing to make a channel for routing the wiring for the light from the right side. However, I decided not to install lights because the lights I ordered from Walthers are more of a soft white rather than the cool white like those I installed on the Tumbler and it would be more of a headache than I want to deal with right now to attach the wires along the chassis in a way that will not be easily noticed. I guess Catwoman will have to ride it during the day.
The shorter piece press fits into the wheel and acts as a bushing for the feel to rotate around the longer axle tubing that will press fit into the left and right munitions clusters.
Since I'm not installing lights the tubular axle was not necessary but I decide to go with it anyway just to get a little practice at scratch building(if it can be called that) and improving a model.
I must say that the wheel turns right nicely.
