boiler sight glass

Thanks for the suggestions. I ended up scoring it with a wheel glass cutter and then worked the corner of a file around the score groove and it broke off cleanly.

Score it deeply with a file and then with luck? Actually there is a sight glass cutter, looks like a hair curler, or similar thing, I used to own one, and I'm sorry but I havent a clue where to get one these days, I do remember some wholesalers having them and some of the boiler manufacturers will custom cut one for you, good luck.

I use one of these but a three sided file and score all the way around as deep as you can I still loose one once in a while. With the wheel cutter I put in the gauge glass and light pressure on the handles and keep rotating the glass until it breaks.

I got mine from Sid Harvey's. I'm sure they still have them available. I would think any plumbing or heating supply house should have them. I would not even try Home Depot or Lowe's. Unless they can sell a million of them a week, they won't stock them. Unless, or course they get their usual quality where they break after you use them twice and have to buy a new tool, then the volume would be sufficient. I have also used an electrode porcelain cutter, although they are not as easy.

I too....

Learned to cut gauge glasses to lenth with a prcelean electrode cutter. It looks like a miniature cast iron snapping tool but works great. It does take "the touch", but after the first 40 or so...it becomes easy. (only 1 real bleeding incident on my part). Chris

My favorite

My favorite is a two piece tool that is hindged, once or twice around the glass then take the glass and snap it, done.
