Cope or Not Cope Crown Molding

[-MIKE-]

I decided to try their "45* and glue-it" technique last time I did crown. (*or whatever angle was half the corner)

It lasted two joints. On a ladder, with a nail gun in one hand, the crown in the other, now I have to put CA glue on one end, spray the accelerant onto the other end, hold perfectly in place and hope it doesn't slip right before the cure.....

With coping, the coped piece can just pivot into the corner, and sort of lock itself in place with the curves on the molding. With a good saw, some stop blocks (or this:

) and sharp coping blades, you get real fast at cutting those joints perfectly.

I actually used the CA and accelerant for the few outside corner joints. I previously would use hot glue, but the CA is thinner and doesn't squeeze out.

Everything you wrote is accurate. When was the last time you saw a drywall corner that could receive a sharp 90 degree angle? With two 45's, you'll have to round off the miter cuts on both pieces to keep from tearing the corner tape. And like you said, I have yet to see a drywall corner that was nailed/screwed all the way to the studs. It's also rare to find a corner that doesn't ramp away from the wall from too much mud. All of these problems can be addressed with coping.

I don't remember seeing any drywall in his display. All, perfectly straight and plumb joints and corners.

I almost asked if he would take all his stuff down to another end of the hotel where they were doing renovations so we could see the thing in real world conditions.

I'd love to hear from anyone in here who has actually used this devise.

My first impression is, but the time I've perfectly lined up this devise and clamped it to the molding, I'm 3/4 of the way through my back cut with the coping saw.

But if it's really as awesome as they say, I'd like to hear about it.

And then the third one second. Hey, it works for me. :)

... and you have perfectly even, well regulated temp/RH, like in Pleasantville, USA.

Ditto ... have taught all my trim carpenters to cope, and which side to do it on, and insist that do, although it seems a foreign concept to south-of-the-border types as a rule.

If I find a mitered inside corner, and it won't be too damn expensive, they *will* do it over again, all the while blaming it on the helper. :(

Well.... that got big spew of coffee!!

Is that like when looking for something, going to the last place you are going to look first and save the trouble of all the places in between?

If you do a LOT of crown, this is a cool device:

it is a little pricey.

but I have seen this demo on this tool and it looks pretty cool also..

http://www.easyc> I do crown molding for a living and today I went to the Woodworkers Show in

I am not a pro, but I've hung plenty of crown. I always find it easier to lay the crown flat on the miter saw, and then make a compound cut with the saw. It seems like there is always a chance of a small movement when the molding isn't flat.

[Lowell Holmes]

When I started running crown, the compound miter saw had not been invented yet. We used and still use the power miter box. It's all a matter of what you are accustomed too.
