I thought I would share my procedure for making trays. I make 4 different sizes, and have work coordinates set for each size in my Fusion 360 setup. I have matching work coordinates setup in CNCjs and 4 dowel holes in my wasteboard for each size.This pic is with the dowels in place.
I start off by cutting my stock to size (X,Y) and putting grooves in the side for clamps. Then I face this side and put in the matching dowel holes. This is done with a “moving” work coordinate “G54”
The dowel holes are press fit size. I can flip this over and hammer the stock down onto the dowels. Now I mill out the legs and handles. Leaving enough stock to hold the piece together really well, about 3/8"+.
Matching dowel holes are put in this side also for the final flip. At this point, I can put the piece to the side and wait on the customer to give me a custom order for the top.
Once I know what the customer wants, I can hammer the piece back onto my wasteboard and finish it up.
I hope this may give some of you some ideas, and maybe give me some ideas.
