Doug,
I used Styrofoam covered in aluminum foil for the BT-7 turret. I still have
the form. It was constructed from layers of Styrofoam. Hard templates were
used for guiding a bread knife to cut the conical shape. I used a positive mold
method. The form was made a bit smaller than the finis
Make your master exactly how you want your turret to look, then give
it a couple of coats of fibreglass. Pull the master out and discard
it. Once the master is out you have a perfect negative replica of your
turret, coat the inside of the fibreglass shell with a mold release,
then layup more fibre
Oh ! I see now. Ron, is this what you were describing, too ? Sorry, I
misunderstood. I guess it would be like this, then, where I sand away the
blue areas
What material is a good choice ? I don't think foam would work for
vacuforming. Even I use fiberglass, I'd like a mold that survives
Frank,
That is what I was attempting to say. You did it so much better!

You can use the "bread and butter" approach:

I'm looking at building a very similar turret for my T55, I'm going to
be using foam and plaster filler. Easy to shape, cheap to buy. Maybe
cut your layers in foam, then simply fill in the rest with filler
I'm going to be fibreglassing mine simply because I have more
experience with it then I do
That's the beauty of the lift method. Each slice defines the widest
point of that slice. When you do the final shaping, you carve down to
the next slice, first with a plane or chisel, then with a soft pad
sander to fair things up. You would have to use something more workable
than MDO though.
The turret is an odd, irregular shape. I don't think I have the skills or
'artists eye' to get it even close to right.

While I have never built a tank or a mold, I have built a number of
boats both scale and up to 20 feet full size. Rather than filling and
sanding, how about making the mold oversize and then
sawing/planing/surforming/sanding to size. It should be less work and
less expensive.

Yeah, I was just trying to get a rise out of you Steve. God knows the

My example picture just shows a dome. The actual turret is kind of a
squashed teardrop shape. It’s about 15” on the major axis, 13” on the minor
axis, and about 5” tall.

What is the height and diameter of the dome your making? It looks similar to what we use for R2D2 droids. The R2D2 domes are available as vacume formed Styrene. Also in Aluminum.

Hello –
A couple of weeks ago I mentioned my plan to build a turret mold. I haven’t
decided yet if I’ll use fiberglass or vacuform. I thought I’d build the mold
and then drill vent holes (and hollow it out a little) if I decided to use
vacuforming.
I want to use layers of ½” or 3/8” MDF to

Those 36v 20ah batteries would work very nicely in the Merkava and save around
20 - 30 pounds of weight.
I'll be watching the prices and see how things look this coming spring.

Heres another site on batteries, I kinda like the ready made batteries
looking like SLAs, very suitable for tanks. The 12AH batteries might be an
option to build with. Could start with 2 maybe, at that size you could use
the batteries for other applications increasing their return value.

I got a local quote from the AU distributor, $1400 for 24v 20ah +
about another $200 for charger - no doubt these genuine ones are all

The Battlebot guys used to run the EVW's at 36v for spinner weapons.
Anyway, I wouldn't seriously try to run my tank at 36v. It's been
proven very reliable at 24v and why mess with a good thing. The 36v

Yep, real deal with all the high end add ons. I'm not sure what Globe TRAC
