A hotel here in town has approximately 300 of these glass lenses for lighting fixtures that need to be cut in half.

The glass tubing is oval , 3" x 4" with a wall thickness of about 3/32" .

I wanted to see if any of you have experience doing this before I begin experimenting.

Hot wire cutter with stainless steel .030 wire. Kitco was a mfg. you have to make a jig if you want to spilt them the 48" way one wire on top and one on the bottom if I read the post right.

but if you are just making them shorter then wrap the wire around the oval shape and turn on the power heat up and put a damp cloth on the spot it will snap off clean then you can flame polish the end just like you would do to neon tubing.

not a plug for Mark at SVP but he might have the wire and Kitco cutter if not he will point you in the right direction.

you might want to warm up the glass in that spot before you cut.

good luck

Thanks for the input guys

I have a lens here just to practice on so I am trying a few different methods.

I tried the kitco cutter .It worked ok but left a few little spider cracks in the cut .

I made a homemade cutter last night that works sort of like a conduit cutter to lightly score the glass all the way around then I very lightly heat the glass and apply a cold rag to it . Really seems to work well . I've made 3 perfect cuts so far without the hairline cracks.

Going to try a wet saw later today for the cuts along the length of the lens .
