saw cut between door jams

[cdubya]

greetings all,

we are installing a flaked epoxy floor in the hokey stadium here and we need to place a piece of flat stock metal in a kerf to act as a transition strip (like a terrazzo strip) between the new floor and the existing. the idea is to have it land beneath a pair of double doors.

my thought is to use a straight edge and a grinder to do most of the cut, but obviously the grinder will only get so close to the door jamb on either side. the doors will eventually be changed out, but in the mean time they of course don't want the existing jambs damaged (the remodel is part of their premiere of their new premium suites).

any thoughts on tackling this? the size of the metal is left up to us, the new floor will be no more than a 1/16" build up above the existing.

oh, and the existing appears to be a urethane top coat on a cementuous underlayment.

thanks

It's not necessary. A proper epoxy floor on concrete includes grinding the concrete (and whatever was on top of it), and even then I wouldn't give more than a 1-2 year warranty in a commercial setting. So if you do that there won't be a level difference.

Talk to your epoxy floor sub and see what he says.

I'm doing this with a pretty big outfit (I sub for these guys when they are busy and I'm not)- they know well what they are doing as far as the grinding and laying the floor is concerned, they do hundreds of thousands of feet a year. It's more a matter of what the clients want, which I think is a definite point where the floors changes over.

Tennant floors carry a much longer warranty than that, even under the abuse of forklifts and such.

Just wondering if anyone had ideas to get flush to the jambs.

Well, that part is not a really big deal. Run a small diameter wheel at the ends of the cut. Then radius the insert strip at the ends to match the radius, more or less.

Your insert strip will look sort of like a very long woodruff key.

didn't think of that, good idea

thanks

How about using a Fein multimaster with one of its various cutters/blades for cutting close to the jamb? Seems to me you could get right up to the jamb without hurting it and plunge to whatever depth you want.

David,

I did think about that. I own one of the rockwell knock offs - which was treating me ok till I had to cut out some pipe with water in it. After a very frustrating day, I failed to remove the screw which holds the blade. The thing is freezed up beyond repair. Probably have to invest in another one at some point though. Just haven't been able to justify the cost of the Fein.

One of the circle blades with a flat on it might work.

I thought of using some sort of rotary tool as well for the last inch or two.
