Watch this video if you would like to take a crack at making your headlights from scratch.

Probably didn't have have a cheap & easily available pressure source that would work as well as a grease gun.

EDIT: This was supposed to be in answer to Lonnie's Post! I don't know what's going on with the forum, but I posted this at about 4:30pm CDT! WTH?

Probably what Mike said. Cheap and low tech. But I like it because it looks very controllable. When he pull it out of the frame the grease stayed put, didn't make a mess and was easy to put back in the gun.

I suspect it's because high pressure manual power grease guns are readily available (and/or 'cause grease doesn't leak as readily as water).

Commerical hydro-forming operations use a water base fluid with a soluble forming lube.
But even clamped together with a huge hydrualic press, they pisses out A LOT of fluid between the dies.

Thanks for the link. I found this simple approach to pressure forming most interesting

Colin Furze did this with a pressure washer.

You can use a pressure washer, they produce more then enough pressure. I helped a friend to make a 2-stroke exhaust pipe. it worked well. You have to install some sort of bleed valve so you can get the air out. You can use a hammer or even a torch to massage areas that are not coming out to your liking.

That guy is certifiable (but amusing), and I wonder what in the world he's been smoking. However, that said, there is something to his water-based method. It's definitely low cost. If you made some decent molds, it could be useful. I think I'd focus on half molds and join the halves by welding or riveting.

Thanks for the post.

Cheers,

I have an old TAB shop projects book that describes DIY'ing similar shapes with a pressure vessel formed from a steel pipe cap. Pressure came from a .38 Special blank cartridge; it fell under the category of "explosive forming."
