Hi,

I am considering building a Bill Pentz cyclone. When I showed my wife the video of your ClearVue cyclone she said I had to build a clear one. I have a couple questions for you and I hope I'm not prying into something proprietary. How thick is the PETG that you use on the ClearVue cyclone? Why do you use PETG and not Polycarbonate?

Thanks,
Randy

If I may be so bold to answer for Matt & Ed, think the primary reason they selected PETG is it can be formed cold, you don't need to heat it to bend it.

Thickness is 8th inch. Unless they've change it from when mine was made.

Regards,
DWD

I think the big trick is that you have to build a form to "form" the cyclone to. Unlike the sheet metal where you use some donuts inside/outside to hold the form while you solder it together. I'd price the PTEG first and see how much it will cost...I understand it is pretty pricey. Add your time and other materials, and see if it will be worth it over purchasing one from Ed and Matt. This may be one of those things that is cheaper to buy ready made.
But it would be a fun project. I think that's how Ed and Matt got started. ;) Jim.

The reason we did not use polycorbonate was because of the tempertures required to form it. The petg is as durable in this application and is much easier to work with.
