I’d say cutting is your best bet, unless you have a heat source capable of melting the glass off. Just make sure you use eye protection and breathing protection of some kind.
Found this in a vintage shop, russian, fifties, with a 35cm parabolic glass mirror in good condition.
LOL, it is labeled as a ‘flood light’, which is correct where the bulb is mounted now . Minor set-back: €795,- did not buy it.
Say Djozz emailed about a recoil thrower before the GT was started
I really hope you guys are going to make this a reality
If you ask Thijsco it’ll be an all Dutch team!
No, I never made one before. And I was bragging about building one two weeks ago, but with my extreme short attention span I skipped it for the moment in favour of other mods and experiments. I is on the list though, and of a few other folks as well.
The idea seems to be at the moment to do some experiments with existing cheap mirrors to see if a good quality recoil thrower is possible. If yes, it would be awesome to have it made in China. But I have little illusions about the process: having something made that is mostly a copy of what already exists (the Q8) is already very tedious, this one will be a new design from scratch!
The best that may happen is that with a prototype (well: contraption) we prove that a great compact 500+ kcd recoil thrower is possible, and that one of the flashlight manufacturers is reading this thread and picks it up and brings it to the market (Thrunite?)
Tbh I don’t care about prototypes or manufacturers, if it throws I will build one from scratch.
The problem is I don’t want to drop $200+ on a custom reflector not knowing how well it will work.
It needs to at least match my 1Mcd aspheric thrower…otherwise it will not be worth the cost.
They’re used for HID lamps in projectors, so that 2 sides of the light are collimated by an aspherical lens.
Slide projectors have them too (but with a halogen incandescent lamp)
Don’t bother, no chance of getting even close to that cigarette lighter thing.
That same aliexpress store has this, but it is glass so a bit fragile to put in a flashlight. And for the price I do not expect it to be optical quality.
There’s not enough enthusiasm either so that we could have a thousand pieces made in China for a reasonable price.
Plus i have no idea how to deal with manufacturers, let alone Chinese.
Maybe rename the topic to “DIY über thrower”.
Awesome ‘host’
But they just stuck a E27 fitting in there making the whole thing pointless (hey, that’s a pun!)
Love the wooden tripod too.
Ridiculous price though.
I did some quick test on the fly with the cigarette lighter
just had the camera in one hand and the reflector in the other
its not perfectly focused but shows how it is, good hotspot and some lighter area around it, which is in my opinion not bad at all
