Polar Lights Spindrift Teardrop Dome

I bought this years ago:

Sadly it shows out of stock. It works very well. You have to supply a vacuum and heat the plastic.

I've made many things with it.

If you just want the dome, send Gil at JAI an email. With it for sale (pre-order) again at Cult TV Man, and lots of interest on other forums for his dome, I'm guessing he will be putting it in production again very soon.

Hi;

      I graduated to the circuit board a long time ago. It works great in my Mattel "Vac-U-Form". Also for the limited space I can do slightly larger parts.

No problem!  But go get a circuit board instead of drilling all those holes.  Glue it to a shallow box that is deep enough to take a vac attachment.  If you use a spare crevise attachment, insert the cut down flattened tip into the box side.  Add spacers as needed to support the circuit board from underneath.

But for your Spindrift astrodome, the plunge mold will also work.

Good luck!

Wow! Thanks very much for all of your kind assistance. The bread pan vacuum former is fantastic. I have a full size drill press that should make drilling all of the holes in a uniform pattern quite easy. 

You've been very generous with your help. Thanks again. 

Yes, you can heat press sheet plastic using simple tools and materials:

The top plywood sheet has a small cutout shaped similarly to the plunge form, but a little wider all around for clearance.  The bottom plywood sheet is open like a picture frame to allow the plastic sheet that gets sandwiched in between to be heated.  You then prop up your plunge form in a vice or similar, then lower the plywood/heated plastic sandwich over the plunge form.  Practice makes perfetc.

You could also try making your own vac former.  A friend had built this for me - a bread pan with lots of drilled holes, a scrap piece of wood, and a sawed off vacuum cleaner fitting.
