Need help on Crown Molding Router Bit

[Gilbert Vega]

I ordered a Freud router bit that would allow me to fab some crown molding out of QSRO on my newly finished cabinets. The bit was Freud #99-402. While this bit has the required profile, the cutting length is only 2 1/4"(h) . I need h to be 2 3/4"(maybe 3"). This is the profile I'm looking for.

The profile is very common at lumber yards as well as at the Borgs but not in QSRO.

Has anyone come across the correct bit? I've searched on Google to no avail and have PM'd Charles without a response so far. thanks.

Gilbert,

How exact do you need to match the profile or is is more a matter of the size being correct. Also, be aware that the 99-402 (as well as the one that Bryan linked) are for 45° spring angle. The 2-3/4" wide molding that you see in the lumber yards is usually 38° spring angle.

Consider doing a built-up crown with multiple moldings so you can get the exact larger size and profile you need. You are not "required" to use a one piece molding! And built-up can sometimes be easier to attach, too.

Yep, Jim's correct. How about a build up using this:

And put a cove molding under:

Or you could use the 99-406 in 2-3/4" stock and make a pass with a round nose bit to produce the cove.

Thanks for the replies. The profile doesn't have to be exact. I just need the end molding to be around 2 3/4".

Charles, can you explain what the significance of spring angle is? I also bought the Freud #99-421 Molding Bevel Cutter and is what I plan on using for the two edge angel.

Brian, Charles
I like the idea you proposed. I'll place an order for the #99-406 bit you showed and use either a cove bit or a core box bit for the final detail.

Gilbert,

The spring angle refers to the angle the molding makes with the wall (or cabinet carcass). If the wrong angles are cut on the back of the molding the result will be that the flat portions of the profile will not be level or plumb. If you look at the picture of the 99-406 above the 45° is called out. If the back is not beveled at 45° this area of the profile may not look correct when mounted. The 99-421 is really geared toward the Wide Crown Molding bits we offer because it makes the 38° and 52° angles. Probably better to use the table saw for 45° spring angles.

Thanks for the explanation. This is something I had not looked. I've got a large chamfer bit that I can use. I really appreciate the "classes".
Take care
Gilbert
