cutting Duraboard

Post by Marilyn Kaminski »

I finally bit the bullet and bought some HD Duraboard to use as a shelf in the bottom of my Evenhead 2541. What should I use to cut it down to fit? Some type of saw ... but what type? And how much clearance should I leave on each side?

Will I need to make changes to my firing schedules once I start using the Duraboard instead of mullite shelves?

(I spent quite a bit of time studying the archive before buying this ... thanks to everyone who has contributed to that wealth of knowledge!)

Rigidizer and respirator in hand ...

No need for a saw. Use a razor knife. You might need to adjust your heating schedules. It might require a longer soak to get the same work done, but it might not. The annealing should be the same.

Marilyn, depending on the thickness of the board, I use either a sharp razor knife or a very fine toothed hand saw - generic type that is kicking around most households and garages.

When the board is 2" or thicker, I like the saw better - it's easier to get a smooth edge and you can gently smooth the edges after you cut, with fine grit sandpaper.

Be sure to vacu' well and do a wet clean up with disposibles when you're done. Better safe than..............wondering about safety/health concerns.

I have found that a dry wall saw works the best. Then I just smooth the edge down with my hand.
