I started this hobby by building 1:35, and 1:16 steel laser cut tanks. For my
first two 1:35 steel models they charged me nothing. The people at the laser
cut thought it was a fun little side project for them. And then fun became an
addiction and things got out of hand.
If you can have something like that built accurately for $ 150, it is worth teh
effort. Steel is for ever. Aluminium and stainless steel is for ever and ever.
I had suggested , about 10 thousand messages ago, that we create a collection
of our CAD drawings for those who want to download and use them readily at
their local laser cut shop. IN fact, I could ask one of my students to work a
couple of CAD drawings, of the most popular tanks, for a minimum price, if
those who are interested chipped in a little $$$. Upload the files to the
forum for anyone to use. It is called globalization.
A Tiger should come first, I guess. Again, the file can be laser cut at any
scale, so it is a good investment.

$150AUD was just that single piece, cut and folded, and that included the
supply of the material. Happy to organise a group buy if you want to, but
shipping could get expensive.
My design is dependant on using certain components for the suspension, as you
can see there are specific mounting hole locations. I may offer this as a
rolling chassis kit if this one works out ok. Thats the real beauty of the
laser cutting, if you want another part you just call them and ask - they
already have it saved in the machine, all they have to do is place a piece of
material on the cutter, press LOAD and press GO, and voila you have an exact
replica.

150$ sounds reasonable to me! Was that for just what was shown in the pic or
did it come with other pieces? Would you be willing to do a group buy if other
people are interested? Very nice work.

I picked up the hull for my M113 this week. After many hours drawing in
sketchup I supplied the cad file, and the hull was laser cut from 2mm zinc
steel, and bent in a single piece on a 10-tonne brake press. I am VERY happy
with the way it came out.
Next is to start to make suspension components, which will be torsion bars.
Front and rear hull pieces will be welded on, also from 2mm zinc steel, the
top will be bolted on and removable. Not yet decided on whether to have a
drop-down rear ramp, part of me thinks if I was going to do that I would have
to make it RC controlled otherwise it just wouldn’t be cool J
The 4 vertical holes are for the motor mounts, which I will fabricate from
steel.
