Chest, Knapp joint

Here is my rendition of the Knapp joint in a chest.

Very nice. Just a sanding with a poly finish?

Is the deer plaque and on the box or did you inlay it into the wood?

Hi Robert
Thanks,
Its pine with sanding sealer, then a light Gold Oak stain with 3 coats of Laquer sprayed on.
I inlayed a maple oval into the pine. Then carved the dished elk and I did an edging around the dished carving to hide any lines. I glazed the carving with a dark brown glaze. Pretty straight forward but I thought I would share the results. I spent more time developing a clamp to hold the end panels for the Knapp joint, as that was new for me.

Butch:

It is a little hard to see from the picture (maybe it's my monitor) is the top a single slab?

Verrry nice work.

No, its an 1 1/2" panel and then there is a 3/4" molding that give the lid the appearance of being thick. The board got reversed, so it doesn't have the same grain reflection as the lid. Another opps!

Nice job Butch. Did you do the joints on the bot? How did you register your parts to make sure the pin and hole lined up correctly?

Thanks
I made a clamp for the end of the bed and measured to the edges of my board on my clamp, from Y=0, and used the bot to mark a series of pin points on the bed to determine a straight line from the edge of the board I mounted for the end clamp. Then simply took a square and screwed a piece of wood to the table and to my end clamp. Then it was just a matter of aligning the edges with the clamp. I am off about 1/32", so I need to redo my edges. But realy didn't make any difference.
To make the pins, I simply set the program to zero at the bed, and then like a dove-tail jig, I even the edge of the end panel with the top of the side panels. This leaves about 3/4", or in this case .78" to be cut by the shopbot.
Worked as well as my $400 Keller dove-tail jig, and faster(plus I couldn't do 18 1/2" on my Keller jig).
Now if I get my joint program to work with variables, all I have to do is enter the width of the board and number of joints to cut and the ShopBot should figure it out on its own. But I ran out of time and had to make the cuts, so maybe some day I can make that program work. That would make joints easy to do.
I read most of your contributions, and appreciate the advice. Sure has helped me at times.
Thanks
Butch
