A friend dismantled his old projector TV, and found a very nice mirror in the bottom of it. The optics on the mirror seem to be high grade to my old eyes. He would like me to frame it. I am always happy to help re-purpose stuff.

Trouble is, the mirror has the shape of an isosceles trapezoid, only the acute angles are cut perpendicular for an inch or three.

How hard would it be to cut this mirror?

I suppose a glass shop would cut it, but would it cost an arm and leg?

Thinking I can frame it the way it is, maybe with an extra little board on the bottom to act as a coat hook. But it would go a lot quicker if I worked with it as a rectangle. (no money to be earned here, I hate to sink huge amount of time into weird angled miters).

thanks for your two cents worth!

If square, I’d use a rabbit bit to cut the channel for a mirror in a frame….but how about using a router bushing along a straight edge or a pattern bit to route out the trapezoid shape?

Not knowing what the dimensions of the trapezoid are, I’m just taking a guess as to how I would approach the problem.

It’s pretty big- I don’t have it at hand- about 27 inches wide, 17 inches tall.

Glass shops will be open today, I’ll call and ask about cutting.

morrors are not really able to be cut because of the reflective coating , maybe just make it into an eclectic design.

Take it to the glass shop, they probably will cut it for free. (Bring a 6 pack)
A cheap glass cutter from Home Depot or Lowes and you can cut it pretty easy, it’s not hard just watch some videos on Youtube.

Most of my stuff comes out looking more like a trapezoid then a square…. LOL! Did you get the mirror cut?

I had several mirrors cut and beveled on top of that and the glass shop did an outstanding job. The beveling cost more than the cutting. These were standard medicine cabinet mirrors that I repurpsed for hall and bedroom use.

I don’t know how or if the standard mirror glass differs from that in a projection TV!

You may find that the mirror coating is on the front of the glass. This is done with some optical systems to avoid the refraction though the glass. The mirror in SLR cameras are like this. If this is the case, then you will need to be very careful not to touch the mirror and be very careful when cleaning it.

Have your say...
