Hi folks,

I know that probably not a lot of people have the new LL Pro Reflector - but the initial reviews of performance are pretty awe inspiring...

My only question is how does someone mount one of these? I mean this thing is glass smile.gif

Any ideas would be appreciated

I was wondering the same thing. Checked put Supra's and see the mount but did not see how it was attached.

JB Weld like we do with an Ikea?

He used two tabs bent over the lip of the reflector to hold it in place. It's hard to see in the pics.

Others (can't remember where I saw it though) have used the grill guard from a muffin fan, some metal (brass?) standoffs, screws & nuts, and spring steel tabs. A more elegant twist on SupraGuy's method. Maybe it was Tescorp? If I remember I'll come back and edit this post.

Here it is: Dazz's Reflector Mount

Oh geez - I see Dazz was here already! Sorry Dazz! rolleyes.gif

Thanks

I'd love to see more photos of the setup and maybe a few other folks ideas

Is this the one you were referring to?wink.gif

How bout a big hose clamp with tabs jb welded to it, then, jb welding
rod to the hose clamp where the clamp is tightened.

the tabs would keep the hose clamp from sliding to the bottom of
the reflector while it is being tightened.

then, a rod of some sort could be jb welded at a 90 degree angle
to the reflector to allow connection to the same piece that the mogul
is attached to.

Maybe a sliver of something (like doughnut shaped) could be fit
over the reflector so that the hose clamp would clamp evenly
then tabs wouldnt be needed.

That might work - but Dazzzla's solution is elegant and I have everything needed to implement his rig (how selfish is that eh? wink.gif ) exept for the reflector (I ordered yesterday)

Yeah, my solution is simplistic, but it works well. It's not something that you'd adjust a LOT, it's more or less meant to be adjusted once, and then left alone.

I'm sure I've posted this in more detail. I don't like the use of JB Weld or the like myself, though I can't see a reason that it would not stand up to the heat.

What I did was: Turn the reflector upside down and trace a circle on a piece of sheet metal. (Galvanised steel, not aluminum, in this case.)

This gave me a circle the overall size of the reflector. Within that, I drew another circle, about 1.5" smaller in diameter (3/4" smaller radius)

I cut out that circle, but left a "bar" across the center, top to bottom, about 3/8" wide. I then cut the bar in half.

In order to prevent sharp contact with the glass I dented in the sheet metal around the diameter of the hole, about 1/4" so that the flat part of the metal would touch the reflector, not a sharp point.I bent the tabs outwards and flattenet them down to the metal using pliers. Some high heat black spraypaint was applied here.

Set the reflector in place, and fold the tabs over the top and bottom to hold it there. Done. I then bent the edges of the sheet metal so that it would stand the reflector off of a surface. The bent edges also allow me to adjust the reflector position and height by a small increment, which is all I need.

It's simple, effective and inexpensive.

My solution :









Those are 2 L brackets screwed together. Then I took my flashing metal and using tin snips I cut 2 strips out of it. I then cut the strips to the correct length and bent them to go over the edge of the reflector. Then I mounted the 2 strips on the L bracket by drilling a hole through them and bolting it to the L bracket. Pop in the reflecter and there it is.

Very nice.... simple and elegant...

since the pro reflector is an ir pass mirror, wouldn't you be really heating up the bottom od the strainer? and reflecting heat back to the reflector?

Well, maybe, but I am going to paint the strainer black, so it should be as good as anything else. I dont think there would be any more heat than what hits the same spot without one of these. Now, as far as light bouncing
off black surface and heading back in there, Im not sure.....


Its not too late to change, but i dunno, maybe I should go back to the drawing board...

Anyone in the know have some advice ?

well, if you paint the inside black I imagine it would act as a heat sink for the IR so that would be good I think

I just received my Pro Reflector yesterday but I have been thinking about how to mount it since I ordered.
I took a piece of 1/8" flat 3" wide steal 4" long and cut about a 2 1/2" diameter hole in it to hold the reflector in place. I then attached a piece of 1" stock to the reflector holder and drilled a hole in the end away from the reflector. I then nothched a right angle support bracket on one side, with the trusty dremel tool, to allow for sliding the reflector mount up and down. I attached the other side of the right angle bracket to a piece of 1/4" plywood. With the mount attached to the plywood the assembly is pretty much freestanding. Once I get it positioned in the projector I will fasten it to the bottom.

To hold the reflector in place I tacked on a couple strips of thin gauge steal to the top and bottom of the base and folded them over with needle nose pliers to hold the reflector.

Once I get a chance I will paint it all flat black.

Once in place it does seem to improve the overall brightness of the picture, I don't have any type of meter to make measurements.

This makes me happy that I just purchased mine yesterday smile.gif
