I have had this house old 1830 home in Boston since 2012 and i have never been able to find a cutter or a bit for these old moldings. I looked everywhere. Closest i ever got is this one cutter. Can anyone point me in right direction? Any help would be appreciated.

I think the only way you can get that profile, is with a planer/moulder. Those beads in the profile, can only be done by a blade spinning parallel with the board. like this. (Sorry, not a good artist, ok, not an artist at all).

The machine would be something like this.

Then you might need to have a custom profile made at a place like this.

The corner pieces were done with a router, and a different profile.

Thank you for your help. i was wondering the same because of those beads never considered moulder. I am engineer but novice at routing. I could have probably done it by router but it would have taken forever

(many runs). But this is great info and i was wondering what tool would have been most practical.

It is interesting that rosettes are same shape..

Ok, I see they do look the same. I would not be surprised if a local lumber shop back in the day made them in house. Back when I lived in Pa, many of the houses in the same are had the same molding, which was made locally by a shop that was around until the late 80's. They still had machines that were originally line shaft driven. Was sad to see all the machines go so cheap at the auction, but it was all too big for my use.

Yeah i assume that might have happened here too... Most of the home has these casings. At least know i can narrow it down to moulding knifes. Went to similar auction, equipment was massive of no use on small scale.

Thanks for pointing out moulder, found already one knife close but still not it. Width seems to be correct 4.5". Still a lot more digging, hope i can find it somewhere

You have a couple of choices. One, find someone to make a bit for you that you can use in a router table $$$. Two, have someone with a shaper make them for you $$$$. Three, find a replacement, same size, different parttern and replace all of them at once $$. Four would be to take one that was in good condition and use it to make a mold and have them formed from some appropriate material $.

If you are doing a full restoration and can afford it, or are doing it for a fee and want everything absolutely authentic, then option two is your answer. But if you are doing your own dwelling and money is no object, then options three and four will do the trick. If you are doing your own place and money IS an object, then for me, the answer is three.

Uniformity would have to be uber important to go to all that trouble. I'd probably pull off enough of the old ones to finish up the most public of rooms, or use one to make a mold and form them from plastic wood, especially if they will be painted.

I did check one place in Boston, person told me it would be $150 per 8 foot to shape it. I thought it was little too much and not worth it. I own the home, trying to preserve as much as I can on this house mostly because I appreciate the old work. It still has its original flooring. i Will go through all this hassle and most likely who ever inherits it will just take it down anyways… 😔

Hi @Kerber welcome to the forum. I would tend to agree those profiles may have been made with a shaper.

Don't know what's available these days but you may be able to make those in 3 parts: A regular board and 2 mouldings, something like these maybe. (if you plan on painting them)

I think you may have a solution TenGees.

Break it into 3 pieces, the two outer being the same, and the center is a plain board cut to the right dimensions. Now look at the two outer and rotate the pic, and it looks like it might be possible to make it on a router table, just need to find the right bit.

I was thinking this way with possibly ready-made mouldings but you may have a point.

Even that could be done with a router table. Just a matter of finding the right bit. I guess it comes down to how far those inner beads come out from the base.

Now you guys have me looking through all my old house pics, looking at the molding.

Yeah, i thought about that.... those beads are the pain. Hard to find a bit with a bead... Or maybe i could just put a "bead strip" on both side and find a rosette to make a profile without a bead. still 3 parts but would need some cleaning..

If you can find the right bit without the bead, it is likely someone with a tool grinder could grind one in. I'm far from an artist, but look at the black line, if you can find a bit that fits the moulding without the bead, then it would be a simple thing (for someone with a carbide tool grinder for carbide bits, or a regular small grinder or file for HSS bits). to cut out the blue portion.

Hi Kerber, those beadings may have been made by other means, in three parts as Paul suggested.
Go to the Lee Valley website, look up Stanley #55 router bits (designed to imitate Stanley moulding planes of yore). There is a Grecian Ogee that looks pretty similar, if not you will need a combination, including the Round plus Bead.

If you cant find you can always have a machine shop make the cutter. Here you see the cutter and holder for a drill press.

Jack, am I right in thinking that the cutter you are referring to is for the rosettes only?
