Yes, the only time I care about the locating pin/s & matching holes, is if it helps with getting more than two parts to line up at the same time because its a complicated assembly that doesn't permit gluing one part to the sub-assembly at a time. E.g. the 3 hull parts to the TWA Starliner kit. O...

A Chopper II made by Northwest Short Line and sold by Micro-mark is the better tool (for this application). You can even set it up, so it can cut consistent length pieces. Albeit, it has limitations, lengths at, or under 1mm are not very consistent.

Couldn't you just buy small sized styrene tubes and rods and cut thin sections from them? :-k I actually tried that first.

Looks good. Going small is definitely a good idea for a first project. One thing to keep in mind, is that when you double any linear dimension, e.g. the length, you quadruple the volume, and finally, the exterior surface is 8 times larger. And I wish I had "gone small" years ago. One of th...
