I have been wanting to build a scale model of a Mack B61 for a long time. Although this model is not called it is obvious that is were they drew inspiration from. I still want to build my own from scratch but I thought building the cab for this one would give me some good insight.

Frame parts and glue up.

Rear axle spacer I glued this up from 2 scraps.

One awesome thing about these full size plans is you can just measure right off of them and start marking your parts.

Gluing the axle in place.

So here is a little mess up I fixed. The axle block came out just a hair too narrow. So off to the hardwood model cutoffs drawer.

Found this piece.

To fill in this gap. I don’t really like showing my mistakes but they happen and the fun is finding a way to fix them so that nobody notices.

Front axle.

I took the front axle over to the router table to round over the edges but the hole in my table was too big and the axle tilted and I ended up have to hand sand it all down. Almost mucked it up.

Quick Mockup

These spacers are for the rear bogies so they can articulate a little bit.

You may notice my holes are a different size. The plans call for 5/16” axles but in my opinion that is way out of scale so I went with 1/4” instead.

Thanks for stopping in.

Front axle.

Great progress so far bj.

Sort of agree about fessing up to mistakes, but, then again such admission will make other modeller more wary. Nevertheless, fixes for mistakes I think is invaluable as we can always learn and use similar techniques in our individual snafus.

This contribution makes me smile :) I’m glad with all that great deatailed pictures on that fine background. And about a failure; Is it a failure when you don’t see it?

Nice drawer two with all that great stuff.

Don’t think of it as a mistake, but rather as a personal feature.

That 3D router machine should come in handy for this project.
