I think losses are trivial whether varnished or not, PVC or polypropylene. I chose polypropylene because the plastics place could make it up in this in a light but strong welded cylinder with caps. I had a few extra supports welded on a couple of months ago to make it sturdier and less prone to fall over in the wind like it did here in July. Remarkably little damage as it landed on the thick copper strike rail and bent it. The impact points were not where it failed recently.
Weather looks OK on Wednesday and I should have done a few coats by then. The motor has been running cool for 8 hours now rotating the former. I now need to work on a different figure as a target as well as a line braking system and I should be set. Takes the better part of a day to organise everything for another shoot.

The next thing you must do is create the tesla trooper.
From the original red alert? He had a back pack and electrocuted people with his gun or the tesla tank or whatever it was slow as shit, but could electrocute those assholes

Hmmm... I sort of thought I did that.
I've fixed the TC and it runs OK. Had to get close to see if there was any sparking but it seemed good. How close can you stand to a Tesla coil anyway? Pic shows single 6 sec exposure.

Just out of curiosity, Since alot of your tesla coil photos are shot in your drive way, does the ground arcs leave marks on the concrete at all? Other than that very impressive TDU, glad to see it working again.

If there are any marks than you can call it Fulgurit. I know a guy taking pictures of these lightning rock-tatoos. Sorry the page is in Czech but pictures are easy to find...

It's an ordinary tarmac/asphalt/road type surface and I have never seen any marks on it. The spark often fans out a bit like in the detail of this 11ft arc strike point. Didn't see any marks on the hire car either .....

I knew about the fulgurite tubes formed from strikes in sand but I didn't know about the strikes to rocks directly. Of course my TC is not likely to cause that sort of stuff on one strike at least and my cap bank is just too explosive although peak currents are similar to lightning but not sustained. Maybe I should try with a continuous firing of my TC through a small volume of sand.

Just regarding your Tesla coil - weapon system, I've got an idea. What about to buy some plastic - toy rocket catapult (or crossbow) put on the top load and hang the string to the arrow. Than just solve some simple trigger and you can aim the lightening directly to the victim...

Don't forget that this is not a weapon, it is a visual effect which I have already demonstrated. My problems are not in reaching a target but in combining all the effects in one shot. To get the visual effect, the sparks need to be multiple at any given point and the feed needs to be slow, controlled and horizontal.
Perhaps you are thinking of Greg Leyh's Lorentz gun. Weighing over a ton it has a range of 30 feet and is probably ineffective against anyone in a metal enclosure like a car. Totally cool though.
No-one commented on how close I was to the TC in the last of my photos above. I was actually about 20 feet away when the sparks were on. Took a flash first then went and turned the TC on while the camera was still in a 6 second exposure in darkness. If you look very closely the kerb is just visible through my legs. Even at 20 feet there is a tingle when I hold the variac from the surrounding fields.

I know it is not ment as regular weapon (everybody knows that - I hope). The point is that small harpoon with the wire fired from the topload could mimick the very long spark directed where do you want to, and it could be filmed like a real action (on running target - a dummy of course...) With fast and sensitive camera you could be able to chatch like the spark is slowly going to the target... It's just a suggestion for another Red Alert - like trick - bit complicated but maybe some movie-effect studio could offer you a contract for such stuff :)
