Have to make about 86 track segments for my Abrams Tank model (for client) - rather than cut them all manually and sticking on the each of the small guide blocks - I decided to set it up in Cut2D and trial fully cutting the unit.

Attached is a side view of the unit (600mm - 24"long). Initial trial for three segments took <5mins. Now that it works well I set it up to cut in lots of 10. Should work fine. The fit is great.
I have also made a jig to drill the hole through the connecting 'tongues' and round the edges.

All the track rollers are already cut from maple and waiting to go!!

I will be adding quite a bit more detail that depicted in the original T&J plans and using a turned Aluminium or Brass barrel and metal railings as well as Plastruct checker-plate #91682, on part of the top carriage.

Hi Tony-I am just getting started with my research on CNC machines and I appreciate your post. I am way late on replying and look forward to seeing more from you about your CNC experiences. This is some super work.

Looks pretty complicated to me.

You got that right.

Advanced techniques are the basics perfectly applied.
