Hi everyone! I need help! I need to duplicate a crown moulding profile that is obsolete and no longer sold in Lowe’s or Home Depot. I have sent a photobucket link for the profile pic of the moulding. I work with wood a lot (framing, construction etc) but I am a COMPLETE noob when it comes to router tables and/or shaper tables. The dimensions are 5/8th” front to back, and 1 3/4” top to bottom. My question is which router bits do I use to get this profile? I hope I explained this correctly. The following is the link for the pic. Thanks for any help.

Looks like you could get by with a standard roman ogee bit with some minimal sanding to round-over the sharp edges if needed.

+1 Brad’s comments – looks like conventional roman ogee?

In case it is not obvious to you:
If you need larger flat area ‘on top’ than single bit creates, then make several passes; pushing the bit up each time to create wider edge.

Do not forget to cut the back side relief into the molding. You need to allow for variations in wall corner joint behind where molding mounts. May also find it easier to cut the relief on table saw before you cut the profile, as it is typically easier to hold ‘odd’ shapes against router fence than table saw fence.

Best Luck

MrUnix, there is a 5/32 and a 1/4 at Lowe’s. Which should I get? The 1/4?
