I have 5 1/4 crown. I have a 10" Comp. Sliding saw...dual bevel...
I have used Rocklers crown jig and love it but for smaller width.
It makes it a no brainer for how to lay it out and keep it right on the edges too.
My blade won't cut it standing up against the fence on it's edges.
I am doing an inside corner...left piece, bottom up, blade is to left at 45
So, if I lay it flat and bevel it at 45 will that give me the same result as when I use the jig...just that it's flat?
I've looked at the pictures of the jig. Looks easy enough to fashion one to accommodate your molding.
I get really confused with angles as well. But I suspect you have to tilt both the blade and the molding. Been awhile since I have done any of that and I always have to think myself into a corner to figure it out. [img]i/expressions/face-icon-small-smile.gif[/img]
I ran into the same thing a few weeks back with a 7 1/2 inch crown.
You need to know the angle the crown will sit at on the wall (38 degrees is typical) and then you'll need to set both the bevel and miter angles to suit.
What are those angles????
Your saw manual should have a chart that tells you. If your's does not, or if you don't have the manual, let me know, I'll be happy to scan mine and send it to you.
Some higher end saws have the common angles marked on the saw itself. I spent some time searching for the chart (it was a saw at work) only to discover the settings marked on the saw when I blew some dust off it! LOL
You can probably find the chart online somewhere too.
Edit: Since this is an inside corner, couldn't you cope the joint too?
