Topic tags/keywords: tenons tage frid 4 shoulders

In the Dec FWW, Garrett Hack paraphrases Tage Frid saying don’t use 4 shoulders around a tenon. Anyone a follower of that Tage Frid that could help explain how many shoulders he advocates and under what circumstances?

Frid advocated not using 4 shoulders unless necessary to hide the joint because it made it difficult to fit the joint and also the reduced glue surface. He preferred some version of a haunched tenon. I’m no expert but it seems that with newer glues the glue surface in a four shoulder tenon should be plenty strong provided the tenon is appropriately constructed? Not sure if link will work but it is from Frid’s awesome book.

Thanks for the book link; appears to work (just not properly on my iPad, of course).

Makes sense. Strange how much effort I put into cuts and surface prep for areas only people like us would appreciate/notice.

Tage Frid devotes a nice section to the full blind dovetail. Cool joint but only you would know it is there! :)
