Pyrex cool tube too long

I was thinking about redesigning my little cabinet. I wanted to put in a small cool tube for my 70mh. I know its small, but the cabinet is also. I want to be able to move the light up and down, but a bake-a-round for a tube was too long for my cabinet. My first attempt was a failure. I used a hammer and it broke.

The second attempt was a success.
I clamped my cutter to the work bench and put a drop of oil on the diamond wheel. Rolling on the work bench against the cutter with both hands to gentle score around the tube. I was off by about 1mm at the end. Good enough for me. This time instead of a hammer I used my torch to heat the glass around the scribe and it split in two. A little jagged in one section, but its good enough to use in my small cabinet.

Thanks. This is good to know. I was under the impression that you could not successfully cut tempered glass.
 
I don't think you can cut tempered glass. Pyrex, I thought, has a higher melting point, not tempered.
 
Nice work. Very ingenious. Got a pic of the final result? Keep us posted. Take care and be safe.
