Domino Question (using 700 with adaptor for 500)

Done with double 10/50 dominos, still rock solid after a year...View attachment 1

When we build furniture with loose tenons, the size of the tenon alone does not determine everything. How well the fit the joint itself is, how other components (e.g. braces, stretchers, back panels, etc.) are used, and how the glue-up is done also affect the structural strength. Before the DF700 was released, everyone (owners of DF500, that's) was using the DF500 to build things with great results.

I'd definitely buy a DF700 if I am to go for building big entrance doors, huge workbenches and the like. But none of them are on my "to-do" list in the foreseeable future. I'm only a furniture maker.

Since my last post, I have started a queen sized bed based upon Woodsmith Classic Cherry Bed plans.  They call for 1/2 by 4 inch by 1.5 inch mortise and tenon joints for the headboard and footboard.  A 500 won't do that.  Would little 1 inch deep joints work?  Probably.  But I increased them to 2 inches deep and trippled 12 mm dominos to get the same 6 square inches of area.  No way to get to six square inches of joint with 1 inch depth since the rails are only 5.5 inches tall.  If you skimp on the shoulders on the top and bottom you could maybe get to 5.5 inches.  Would that work?  Probably.  But I like to build stronger than required, no lighter and hope it doesn't fail. 

I don't think most chair joints are too heavily stressed but the back leg joint to the support under the seat would be a concern with mortises only 25mm deep.  But the plans I use probably only call for 1.25 inches deep so the 500 is probably OK for the chairs I make.  But it cannot do what the plans call for on the bed.

Very large or heavy-built beds sure will benefit from bigger joints offered by the DF700. The DF500 can handle ordinary beds that are properly designed. This Korean woodworker shared an example, using the DF500:https://www.webstagramsite.com/media/B2OyXzSA_EE

Many Ikea beds are built with dowels and metal brackets. Dominoes used with brackets will be stronger than the dowel version, I'm relatively sure.
