I was just reading a review by DeLayne Peck of a drill/tap and wanted to pass this on. There are two types of taps. Cut taps and Form taps. The cut tap function is obvious but the form tap re-forms the metal [or in this case wood] to make threads. There is something called percentage of thread or ”POT” where the POT is increased when a smaller pilot hole is drilled. Me thinks that some research on drill and tap sizes and some experimention with CA glues or wood hardener [as mentioned in DeLaynes review responses] acceptable thread strength could be achieved even in soft woods, MAYBE!!!!! Let me know.

I never put much thought into it; I just bought the tap set from lowe’s and got to it.
I do use a slightly smaller drill for more thread engagement.
The thin CA glue I use is the titebond brand.

I have tapped hardwood successfully. I haven’t tried soft woods.. I usually use threaded inserts for soft woods.

I have found a real useful use for threading wood. When I make a new insert plate for my table saw, I drill and tap 4 holes for 8-32 set screws to level the plate. I use one size smaller tap drill to ensure a tight fit that will stay put.

I like yer comment MrRon. When I recieved my dads saw it came with a hand made aluminum insert that doesn’t fit really well and rattles like crazy. I think I’m gonna do a nice hardboard zero clearance insert with adjusters like yers.

I do the same with my zci’s.
Much easier to level than the hot glue method or trying to plane the zci to the right thickness.
