I was working in my workshop and found some balsa wood (from my R/C airplanes) it is flexible and when making wet or rub it in
with a special product (water just take more time same result)
you can make ANY chape you want.
After, you can foil it with tin foil so you get a beam as you want,
go test it out right away, just wanted some opinion on the heat,
myself think it won't hurt wood need allot of heat to flame but
balsa wood is pretty soft wood and maybe it burns to fast!
- Or you can let it paint chrome so you have almost the same reflection as a mirror but then in your own shape !

ok I bend the wood in a nice sqaure bold kinda shape, and it will be nice and smooth.
Somebody alrdy tried this, or am I wasting my time with this ?

with all the heat these lamps generate i believe it will burn the balsa wood in a second. this wood is to soft and can be very flamable. anyways when heat is applied to balsa wood it tend to bend and curl up so it won't retain its shape. it'll leave you back to square one.
a few days ago i went to walmart and they have metal kitchen pots and pans (all sizes, very high polish "chrome look") that look like it would work very well as a reflector. they come in different sizes. i think you'll have better results with this than with wood.

yeah I guess you 'right, I think I go for inox anybody know this material it's a VERY shiny metal, I go check it next week out !
I guess kitchen pots are made from Inox.
But pots are not in the shape I want I really want the better reflector, cause I think if you can aim right you don't need as many watts and you have less heat!

You can make any reflector if you can do that with balsa wood. Just impregnate the balsa with some fire retardent when you are shaping it. Or shape two of them then make a form and pour a thin shell of fast drying concrete powder (Called "RockHard", $5 boxes at any hardware store). Then paint the shell.
i think you guys are going about making a reflector all wrong. There will always be "wasted light". I dont think there is any way to actually collect all the light or direct 100% of the light forward. just no way. all commercial projectors waste light.
see image below: this is the lamp of my sharp projector. as you can see the reflector is just a small disk (3") on the bottom of the lamp. its not complicated. it doesnt reflect all the light forward.
the bulb hangs over the reflector with about 1" of space between them. as you can see there is wasted light but yet the projector gave a good image. so maybe the whole reflector thing needs to be rethought and redesigned.
my epson projector works with a different style of lamp but still wastes light. i say this because i've ran the lamp outside of the projector to see how the beam of light spreads, and surely enough it speads all over the place. concentrated beam in the middle but it has a large ring of light all around it. so i think you guys are wasting alot of effort on something that doesnt have to be so perfect like some of you might think.
