A novice trying to find a 10" (or less) table saw blade with a 3/16
kerf. Only need 3/16" for special job making grooves. Don't want to deal
with dado (wobble or stacked) or making 2 passes/groove. Seems like there
should be a 3/16" blade available somewhere.
Any suggestions as to where I might buy such blade would be greatly
Mount your router in the router table with a 3/16" bit? I have made
plenty of plywood shelves using a 3/4" router bit and a routing guide.
I have not seen a 3/16" saw blade. So what is wrong with a wobble
dado since a regular dado seems to make a 1/4" kerf or wider?
Ask around for a bent or warped blade. You could even bend or
warp one yourself. It may be hit and miss to get it to be
exactly 3/16, but I bet it wouldn't be too difficult. Kind of
like a homemade wobble dado.
I know I have a few blades that have developed a wobble that
causes a wider kerf, but I have never measured to find out how
wide it was exactly. I just put them in the use them as
frisbees or to build a clock pile.
But a targeted-width kerf IS a dado. Why do you want to make a
dado on a saw, but not want to deal with a dado saw blade?
Slitting blades of various widths can be custom-made, of course;
Router/shaper slitting blades are probably available, but
will not likely fit your table saw arbor. Enco sells a 3/16
inch HSS saw blade, 6" OD, 1" center hole, which could do
the job, but it's intended for a metal-cutting horizontal mill.
Their part number is 370-5650.
Pardon my confusion, but unless you're going to be using the blade in
a dedicated saw, or for general cutting, you're still going to be
faced with a blade change each time you need the wider kerf. So, I
don't understand the reluctance to use a wobble dado or, as previously
suggested, a stacked and shimmed pair of thin kerf blades.
If this is a "special" one time only job and a 3/16 router bit isn't
practical for some reason, before buying a specially fabricated wide
kerf blade, I believe I'd opt for a couple of less expensive thin
kerfs. You'd wind up with a couple of extra blades for general purpose
cutting after the job is completed.
Try a 1/8" blade, set the fence up so when you flip the board you cut
the 1/16" for your 3/16" cut (that is assuming you are doing a groove
length wise) if your crosscutting a groove a stop block with a 1/16
shim would work.
