A question

[wrinkles2]

I posted this in Brush restore, but got no response so i'm posting it here.

I have a couple boar knots coming my way in the next few days, one I Have a Handle for.
I am searching for a Second handle; here is where my questions start.
First
Here are the Dimensions of the knot:
Knot (hair tuft as it comes out of sleeve): 20mm
Sleeve diameter (minimum size hole would need to be to accommodate the knot: 21mm
Collar diameter, outer edge to outer edge (this isn't really that important, as most people just leave the collar to sit flush with the handle - meaning the collar is visible, but if you don't like that you would need to account for the size): 24mm
Height of sleeve: 12mm (13mm from bottom of sleeve to top of collar, but again, the collar will sit flush so it wouldn't actually enter into the hole in the brush handle)
Hair loft: 55 mm
Total height from bottom of collar to top of hair: 68mm
To Be Clear, the Collar is the rim that the hair comes out of and not the plug that gets glued in the handle right?
If so, I Do wants the "Collar" to be visible, so that would bring the knot back to 21mm.
Now for my next question, I understand that these knots expand so how big does the hole in the handle have to be drilled to accommodate it?
I have a few questions about my other handle and knot, but will post them later.

Might get more responses if the subject line were more descriptive.

Anyway, I personally can't help, but there's a guy who makes handles for whippeddog.com, maybe you could contact him directly? Just a thought.

I think I Will Contact the Guy that is sending me The Boar knot.

Wrinkles, you might also contact B&B member Rudy Vey (that's both his name here and his real name) as well. He's a restorer and knows more about setting a knot than anyone I've ever talked with. He's a great guy, too!
