Using a stake is a good idea. I'll remember that next time.

Joe, Did you try a slaters stake at all with that slate? I find that with my stake the brakage is very little even the thicker pcs same with cutting.

Breakage rates depend on the type of slate and the thickness. For example, I have been sent some Brazilian slate samples that were impossible to punch without breaking the slate - standard thickness. They were like trying to punch holes in dinner plates. They shattered like glass. Couldn't cut them with a slate cutter either.

Also, thick slates are not so easy to punch with a hammer. You will ruin a Stortz (for example) slate hammer trying to punch holes in a 3/4" slate. Better to drill them with a 3/16" masonry bit. Thick slates aren't affected by nail heads rubbing on the underside like standard thickness slates are (i.e. 3/16" to 1/4"), so drilling the nail holes in thicker slates is OK.

Also, a pin punch bought at any hardware store comes in handy when you need to punch holes in a thick slate.

try punching holes on partial pieces before cutting the slate to final size- a small nailset works really well for punching if you also support the slate on your thigh- bad grain structure in a slate contributes to alot of punching waste

Are you punching free hand or with a slaters stake? A stake should help with the support of your slate pcs. The support is just like at the quarry with there old timer punching tools.

Depends on what type of slate you're punching.

Oh, I forgot to specify, I'm asking about punching holes with a slate hammer (not the punching post on a cutter (which I don't own.))

What would you consider an expected or acceptable breakage rate when punching nail holes?
