Stripping Sandwiched Form Plywood


I am trying to "help-out" our forming/framing crew owner here. Partly out of sympathy, because he is so dumb and disorganized, partly just to help him get his work done faster.

He did some stair forming. Laid his form ply vertically, so it would be sandwiched between a block wall and the newly poured stairs. Instead of listening to our site forman, an placing strategic cuts in his form ply, he used full sheets. Then he left it for weeks, so the plywood could get nice and wet and swollen.

It isn't coming out of there. We require that he cut off the plywood that extends out of the form, between the block wall, so there is at least a recess that we can caulk.

We suggested using a reciprocal saw, and pulling, chiseling, or whatever means to get the remaining bits of plywood out.

Do you guys have any other suggestions? If there was something like a large freud trim saw, that might work.

He is working between concrete stairs and concrete block, so it is tough. Chain saw isn't going to work.

He has several stair forms to do.

Thanks for any tips or suggestions. it will reduce the whining I have to listen to.

Re: Stripping Sandwiched Form Plywood


A fein detail saw might be the ticket- the blades are expensive, and you would probably ruin a couple running them into concrete like that, but from the sound of it, you aren't paying for this mistake?

Re: Stripping Sandwiched Form Plywood

Re: Stripping Sandwiched Form Plywood


Possibly a roto-zip with some wood-cutting bits.

Another thought, a small hand grinder with one of those wheels with the chainsaw style teeth that wood sculpters use. Even a hand grinder with a small carbide toothed blade - dangerous but effective.

Re: Stripping Sandwiched Form Plywood


Somebody needs to spec expansion
material in those locations,
and find a sub who knows what
he's doing. (Nice guying the blades is buy or not)
The MultiMaster would be great
if the other guy is buying the blades.

Having used a grinder with a saw blade on it, I cringe at the thought of running such a dangerous tool so close to a material like concrete.

I suppose that if you have no concern for life or limb, it would probably work pretty well though.

Re: Stripping Sandwiched Form Plywood


Thanks for the thoughts and suggestions.
I think we came to some similar conclusions Well I will leave it up to this guy. He has not supervised his crew properly.

Don't feel too sorry for him. He drives a hummer.

I don't know how stupid tradesmen end up making money sometimes...

Yeah, my question exactly, Why do we hire these guys? I don't, but get to be saddled by them.
Bottom line, is they are cheap and that's what my superiors care about.

It might make the concrete a little too black. I think it would be [email protected] hard to burn anyway. Maybe a plasma torch held there
