Hi: I just finished building a slide assembly for my Shopsmith that allows
me to easily make "loose" mortises. One question remains...

Should the "loose" tenons be the same material, or would a more stable
material such as tempered fiberboard be the prudent choice. The fiberboard
is precisely 1/4", does not swell and is very strong. Not to mention, easy
to "store" in the shop.

Does anyone have first hand knowledge with loose mortise and tenon
construction.
