Great big dirty cove bit?
G'day,
I'm up to the point of doing my crown moulding for the bookcase I'm building https://www.woodworkforums.com/f40/wa...3/index16.html
And I'm stumped, can anyone tell me where I can get a great-big-dirty-scary-as-hell cove bit? I don't have cast iron undies to do it on the cabinet saw.
Below are 3 shots.
The moulding I'd like to do, and a compromise using one bit which I would have to barstardise using other profiles, the one I can do with bits I have on hand right now but it's not really to the scale of size I'd like to do.
Timber that's been waiting for a year now calling out to me everytime I go down to the shed is a nice bit of t/blackwood 100mm x 50mm x 2.4m

The closest thing i have seen to a cove bit that size is a bracket foot moulding bit:

Thanks Joez , it's big but not the right profile. I'm currently working on what bits I'd need to make the moulding in the first shot.
But it's not a big cove.

From joez's link, why not use one of their 186-4705 Vertical Panel Raiser - Cove router bits?
.
I know you believe you understand what you think I wrote, but I'm not sure you realize that what you just read is not what I meant.

Okay...
Ian, nope don't need to match anything exactly, just trying to find ideas and then sort of interpreting from there. Yep, only need about 2.4m length, but I'm not looking to go out and get it done externally as that takes away the fun/misery.
I'd use moulding planes, except the one I have would only do a rabbet. If I go with the first profile it would be most likely in a few bits.
Yeah, Woodwould, the vertical cove bit would get me some of the way, pity it's not a Whiteside bit as I can get my hands on them.
Appreciate the help and ideas.

Gday Waldo
I admit up front I'm not into advanced routing/moulding yet.
BUT, that said would a moulding knive like in the attached website be any good.

Hope the attachment sticksHave a good one

For limited production, or one-off, consider multuple passes with a variety of standard bits. Like here: https://www.woodworkforums.com/f40/flag-holder-75678/

After lots of leaning, pondering, thinking and looking at my navel fluff I'm going down the path of the profile of the first shot.
It'll be done from various profiles. I've not done a crown moulding before and I had in my head the moulding I wanted to do but found I couldn't find the size cove bit I want.
So down the path of uncharted waters I go, how I come out at the other side will be interesting. But before I stuff up good timber I'll do dummy runs using off-cuts I have lying around the place.

Waldo,
I have quite a few profiles of knives for my spindle moulder.
I would need to confirm with you that I have the correct size firstly of course.
You are welcome to bring along your timber and enthusiasm to my shed - perhaps an overnight stay with the family in the self contained cottage.

G'day Ian,
That's not too far off how I figured I can tackle it. I reckon though I could get the top two pieces - the 1/4 round and r/ogee with a fillet in one. Or maybe not?
