A have some tapered cherry table legs that need to be thicknessed from
2" sq to 1.5"sq at the tops. The legs are alredy tapered to 1.5"
(which needs to come down to 1.25") on two adjacent sides starting
4.5" down from the top.
I know I can do this on my table saw with my jig, but Isomeone
mentioned to me that running them through a thickness planer will
maintain the taper. Is this true?
The problem seems to be that you are changing the amount of taper. Right now
there is 0.5" of taper over the whole length, going from 2.0" to 1.5". When
you get done you want to have 0.25" of taper over the length, going from
1.5" to 1.25". If you were maintaining the same taper I could see building a
sled to hold the legs, tapered side down as it ran under the planer's knives
as you removed 0.5" in multiple passes but that would result in the bottoms
being reduced to 1.0".
Dare I point out that you are _not_ 'mantaining' the taper?
If you're taking 1/2" off at the top, then taking only 1/4" off at the bottom,
requires a _different_ taper.
Regardless, it's d*mn difficult to do something like that with a thickness
planer. However, with a -jointer-, it is possible. Quality of results
is not necessarily predictable -- depends greatly on the jointer and the
skill of the operator.
