Moving a thread over from a different forum.

Here is what is planned:

A routed 2 lane analouge 1:32 scale slot car track, completely designed in CAD, and then formed in our own CNC router. The plan is to sculpt all elevation changes in our CNC machine, and get a very precise end product.

What has been done?

The frame is built an hanging in our basement roof, with a temporary scalextric plastic track built. The CAD model is closing in on becoming finished, and the CNC machine works, sort of.




Early planning. Rally stage has been scrapped








First attempt at elevation design


All elevation finished. From here on it has been a bunch of fine tuning and construction design, which is yet to be finished.



The current state of the design. You may see that the corcsrew has been split in to 16 mm shhets. These are the pieces of MDF that we are going to eventually mill out, hopefully in about a month.

After a full afternoons work (yes, this model is that complex) the track is 10 mm wider everywhere. I have also put some elevation pieces on another MDF sheet, that we will use as a test-rout in the near future.

Just quickly....the indent/curve on the two ends of the layout, Why? just make a sweeper at least at one end.....and too many pieces, biggerlonger sections will give you a smoother track. You will be able to manipulate the mdf once routed.

What’s the footprint for this and running length
Track footprint is 3.1 x 2.2 m, so quite small. Running length is somewhere around 13-14 m.

I will look in to this later today, and see if its worth another few hours of work.

You just wait and see...

It´s been a while, but without any better way of putting it, things are getting real!

First we had to re-flatten the router surface, before screwing down our MDF


Today, we cut out the separate pieces for our first elevation section, and I testfitted everything

Using wooden plugs we glued the pieces together. The router is currently getting service, so the next step is postponed bh roughly a week.

After changing out a broken spindle, today was going to be it. Unfortunaetly, the z distance was way off towards the end of the programe, and we were forced to stop.
