How to set up a bevel cut on a table saw

Hello Carpenters,

I am looking for a jig solution to achieve a 66 degree length wise bevel cut on both edges of a 14 foot long 5" wide 3/4" thick PVC Beadboard.

The cut needs to be made on a table saw that only tilts over to 45 degrees.
I know I need a 21 degree fixture to achieve the 66 degree angle.
My question is how to create it and where/ how to safely place it on the table saw. A detailed pictorial solution would be appreciated.

Thanks in advance,

David,
Lunenburg (MA)

56 degree Bevel cut
by: Anonymous

Hi Gary,

You are correct what I said didn't make sense about flipping the piece over(senior moment). I cut a few short sample pieces what I discovered is my degree of angle was off, should be 56 degrees not 66 degrees. Set blade angle to 34 degrees.

Tacking the material to a length of timber so that it is held straight whilst I pass it through the saw/fence. This will be used as a final trim piece, will need to clamp instead of tack.

Cutting this this trim piece is still a several weeks off, I am old, I work slow, I am retired so I have plenty of time.

I will let you know how I made out.
Thanks again for your help/suggestions.

David

Bevel cut with table saw
by: Gary

Hi David,

In this instance, I would:

A: tack the material to a length of timber so that it is held straight whilst I pass it through the saw/fence
B: set the depth of the blade so it only just protrudes enough to cut through the material
C: set up some rollers either side of the saw to keep the material flat and supported whilst cutting
D: get an extra pair of hands or more to help
E: take my time

What you have just said doesn’t make sense.
When you do the first pass you have the the material up on edge cutting the bevel on the bottom.
Then that cut/pointy edge is up in the air when you make the second pass and cut the opposite edge.

Good luck,

Gary,
Thank you for your suggestion. Yes I had thought of that option however as I mentioned this is PVC and it is fourteen (14') feet long.

PVC material is not all that stable at that length and would flop around quite a bit. Trying to keep it upright against the fence would be difficult, I can't afford a wavy bevel cut.

Even if the first cut was successful once you flip it over the make the second bevel cut you don't have a square end against the fence the material would be standing on a sharp edge making it more unstable. I believe to maintain the stability while making these bevel cuts the piece needs to lay flat.

How to set up a table saw to cut 66 degrees
by: Gary

Hi David,

From my understanding, you want to lay the board flat on the table saw and pass the material through the blade, tipped over at 66 degrees - quite an acute angle that is further than the table saw will bevel over to.

However would it work if instead you set the saw to 24 degrees instead (90-66) and pass the material through standing up vertically instead of laying it flat?

Let me know if that solves the problem.
Cheers,
Gary
