Cutting Plaster on Wood Lath

[Article 90.1]

The vacuum attachment for the rotozip works well. Add some blue painters tape to the base plate to reduce any marring of the walls, just like you would on a jigsaw. Ever get worried when the molten hot rotozip bit falls into the wall, I sure have

Or adhesive felt.

One more thing to be wary of: If you're not careful, it's possible to push half of a slat in where you're working, and pop out a hunk of plaster on the other side of the stud due to the slat see-sawing.

Don't ask me how I know. :roll:

I won't ask, because I found out the same way.:grin:

I use these hole saws for cutting in old work round boxes . works the best for me .
cuts plaster like butter . I do about 30 full rewires a year and had this bit for over a year and still cuts like the day i got it. here is a link https://pga1.readyhosting.com/ProFitMPHandyKitsE.asp

I've always used metal old work boxes and madison bars. The metal boxes are much smaller and leave more room for crumbling plaster. I use a screwdriver to chip away the plaster and then a hacksaw blade (32 tpi) to cut the lath. Works very well. Have been doing this for over 30 years...
