We would do this on a shaper with a custom profile knife. A knife cut to that size is about $200.00. Wood cost is under $100.00 and labor is $200-300. The issue would be the shipping, where are you located and what lengths can the sticks of molding be?
I would check and see if there is a planning mill in your town. They might have created the trim or have the capability to re-create that look. We have a planning mill in town and their catalog is extensive. I will look and see if they have this trim.
I would use my smoothing plane, select hollow and rounds, beading tool and rabbit or shoulder plane. 20ft could be hand planed in your material of choice with carefully selected material to avoid reversing grain. It would be a fun and rewarding way to create a matching moulding profile.
If it isnât a lot, grind your own router bit (a friend who is a carpenter and works a lot with mouldings grinds his own from rather ordinary steel even if he is working oak because, as he says, the cutter profiles will have to be sharpened anyway and sharpening carbide is a real hassle).
An angle grinder with a couple of wheels should suffice to rework som cutter blanksâŚ
Have you thought about using a CNC milling machine?
Weâre up in the middle of nowhere, and the only CNC machinist around knows his worth.
I run across this all the time, someone wants a foot of trim they are missing. I have a woodmaster shaper which would easily do your trim. However, a custom blade would be several hundred $. I you want to pay for the blade (I keep it), Iâll run 40â of the trim for you for free , thereâs not that much needed. With one blade and a counter weirght it would require 4 runs though my machine, 2 each for the front and back (I have blades for the back). Let me know and Iâll price out the blade (from woodmaster) for you. Youâll have to sand and finish. In the mean time Iâll look and see if I have a blade thatâs âclose enoughâ

With all the other prices mentioned here, maybe your own milling machine comes within reach and can also be used for the next projects in this direction?
I wonder if it would be possible to sharpen up a metal 3d print. You have the ability to design it, and get it printed. It would be an interesting use case.
I donât know if the technique has changed. I once had a small object printed in âsteelâ, but actually what was used was a mixture of steel powder and adhesive where the adhesive was then replaced with bronze so the result was 60% steel and 40 % bronze. I donât know if that can be sharpened but if it can it would probably last for a long enough run. They used to make sharp tools out of bronze for at least 1000 years.
Bronze age CNCing.
I own and use a CNC on an almost daily basis. This is something that can be done on a CNC but it can be accomplished much more economically with a shaper or router table.
I wouldnât think CNC would lend itself to pieces of any substantial length like is needed here.
