They have been made on duplicating carving machines for a long time. Purely mechanical,operator traces a master template with a stylus and 6 blanks on either side are cut. The results desperately need cleaning up with sharp tools but the shape is there.

Wow! I did not know that!

After a little googling I see what you mean. One of the machines I saw advertises that it can duplicate a ball and claw leg in less than thirty minutes.

Looking fantastic there Dave.

I think many knee blocks were made out of a piece sawn from the top of the leg stock they are attached to, to get the best possible grain match with the leg, ideally that join will be seamless.

That's ingenious!

I wish I had thought of it. I have more of the 8/4 stock that the legs came from and it should have a similar grain and color, but I don't know about seamless.;)

I'm cutting the blocks out of side grain and face grain as the aspect of the leg requires to get the best match I can. That one pictured is a "throw-away" trial piece. When I settle on an acanthus leaf pattern for the knee it will likely require a slightly different shape for the knee block.

Awesome, Dave!  I'm proud of you buddy...this kind of thing takes mad patience.  I ain't got it.

You're doing a great job on this, keep it up!

great job on the legs Dave.  You sure you haven't done this a couple of hundred times before.:)

Thanks Eric. This kind of project, with a multitude of discrete steps is perfect for the schedule I get in the shop during the summer.

It's painstaking work, but you definitely have the patience. You just have to dive in, post up a journal, and then there's no returning...;)

Thanks Chet.No question, these my first B/Cs. There are numerous tell tale indications of my inexpert carving skills that are  uite apparent in person which don't really show up in photos. The next ones I do will be more uniform, but that's just something you get after several repetitions( I hope). Overall I'm well satisfied with the results.

These little legs are making things harder than if I had made a standard size ball and claw for something like a stool/chair/highboy/etc. So far, all told, this is the pile of off cuts and shavings I've taken off of the leg blanks:

My next step, which I have been avoiding finalizing for the longest time, is to design a pattern for the knee carving and make a template to use on all the legs.

I went through several unsatisfactory iterations

before deciding to go with a more traditional acanthus theme:

I traced it out on a piece of disposable plastic cutting board (thanks Mary May!):

And cut out the pattern:

I found the drawing and settling on a pattern to be one of the most difficult parts of the process so far. The uncountable variations on the theme, and the myriad versions of actual historical carvings you could emulate are overwhelming. My brief study shows that there are certainly conventions in the carving of certain elements of an acanthus leaf or a Newport Shell, or what have you, but after that you can do pretty much whatever you want.

For me, the incredible diversity of styles makes it harder than ever to decide on my final version. I would be better off having someone say: "This is how it's done. Do it like this."

As it stands, I'll probably have to simplify my pattern slightly. It's still a little too detailed for the scale I'm carving.

That's pretty cool, Dave. I've often wondered why the leaf design was traditionally done on the knee above a claw. One would think a feathered knee to be a more logical choice.

One of these days, I'm going to carve a set of B&C legs, with hairy monkey feet!

Strangely enough that is a "thing". Check out the hairy paws here.

Okay...so...I have been making some incremental progress which is not all that interesting, but I was asked for details, so here you go.

I tried to match the grain for the knee blocks on some stock I have, and then cut out some blanks. I made some templates (seen in the upper right of the photo) for the band-saw cuts I would have to make and marked them on each blank. Each is numbered as to their position.

I put the aprons in each of their places and struck a knife line for the bottom edge.

I also put in a pencil line which coincides with the back side of the apron.

Then I made a little glue block which I will later use to position each of the knee blocks as I individually glue them into place in their prospective spots.
