Large width crown moulding

[Woodboy]

I have some seven (7) inch crown molding (or is it moulding?) that I would like to install, but my little 10” Delta CMS is too small. Any suggestions? I want to cut it “upside down and backwards”, bypassing the need to cut the bevel and miter. Would a 12” miter saw work for this size material? Any one installed this large sized stuff?

The Depot advertises a 12” Rigid CMS on their rental website, but of course the guys in the stores (Denver metro) act like they never heard of such a thing and only have a 10” Makita for $40/day. Hate to buy a $400 - $600 saw for a small project – or rather I should say my wife just does not see the merits in that.

A conventional 12 inch CMS will only do about 3 5/8 crown upside down and backwards. A 10 inch will only do about 2 5/8. By conventional, I am talking about a CMS that has the motor directly connected to the blade and thus on the right side of the blade and in-the-way for moulding cuts on that side.

There are some CMSs with the motor up and out of the way - the double bevel types. You might be able to do a 7 inch against an improvised higher fence with them but I would want to check it before buying the saw. These are more money than a simplier conventional CMS.

The other way to go is to cut the moulding flat on the table of the CMS. Even then you will need a 12 inch to cut a 7 inch moulding. It seems like you could need a double bevel for this too but I do not cut crown this way so I'm guessing.

I have cut crown on a CMS standing up on the angle that it will sit, and then just having to miter at 45 deg. You have to make support wedges for the crown to be pushed against the fence and stay tight while cutting at the angle. You should take a small cutoff to the saw you want to buy and set up the piece to see if it will clear or if the motor will hit. That crown may be too tall even for that procedure.

Laying flat you will have to set the miter and bevel, but still check to see if the moulding is too large. You may need a SCMS.

here's an idea:

currently, the Makita LS1214FL , is $452.54 delivered.

I know it's not what you were wanting to do, BUT, this is a really, really sweet deal for a 12" CSMS. In addition, it comes with a mail in rebate for a Makita BDF452HW, a 1/2" 18V Lithium Ion drill/driver. The drill is currently selling on ebay for about $162 plus 18 for shipping (that's with 2 days left on the bidding, so it will more than likely go up). You could effectively get this saw for ~$250-260 bucks when it's all said and done. Plus you could sell your 10", and maybe only be in the $200 range for a new saw

or, you could buy the saw, and sell it when you're finished and probably make a little money.

I've done molding that size. I use a Bosch 3915 10" slider. Nothing smaller will do and it doesn't have to be larger. Cutting on the flat isn't anything special. Buy some cheap crown and practice.
