I did my first raised panels on the table saw today for some doors to a
cabinet I'm building for SWMBO's scrapbooking 'tools'. They came out
great, after I sanded for 30 minutes. I ended up with a burn mark or
two on almost all of the angled cuts.

I spent a lot of time aligning my TS blade so I'm pretty sure its lined
up right. I think the issue was just that so much of the blade was
exposed to the wood and the fact that it was tilted 14 degrees to the
left meant that the panel was resting, so to speak, on the blade as it
passed through.

Is there a wax or rub to put on the blade to slow down the burn? Or is
this just a thing you have to live with trying to use a TS for something
a raised panel bit in a big router should be doing?

Thanks.

What kind of wood were you using? Some woods (i.e. cherry) are more prone
to burn than others. Did you cut the whole depth in one pass? Sometimes
"sneaking up" on your final depth and making the final pass light will solve
burning. I often use a product called "Dri-Cote" (It's made by the same
people who make "Top-Cote", just in a blue can) which is a blade lubricant
to keep cuts smooth. --dave

how much were you hogging off on each pass? 1/16" is about right.

Mike,

May I offer several suggestions for you to try. A number of things can
cause the burning you're experiencing and I may not hit on the one (or more)
that may be causing your problem but here's some things to consider:

1. Sharp blade with minimal runout. I would have to research the exact
runout for a WWII blade but mine is about .001" and I get no burning -
unless I cause it.
2. Is your fence aligned with the blade or is it kicked out a few thou in
the back? Make it parallel to the blade.
3. Is your fence solid - is it flexing on you as you push stock thru?
4. Is fence perpendicular to table - for the full length? What kind of TS
and fence do you have?
5. Did you use a zero clearance insert and is it flat to the table?
6. Some woods burn easier than others (maple for instance) and the slightest
misalignment or side pressure will cause a burn.
7. How did you support the panels as you were cutting them? Attached to a
jig or just free-handed it?

You can see where this is headed and you now must realize that a lousy few
thousandths of an inch can make the difference between sanding for hours -
or not. There are many reasons but you may have the answer already by simply
looking at the panels. Did all of them tend to burn at the same spot - near
the end? If so, I'd be looking at the fence not being parallel, you're
technique of not holding steady pressure (or the jig isn't) etc.

You said you're pretty sure about the TS being aligned. As you can see,
"pretty sure" may not be close enough but then again, it depends on how anal
you are about these things.......

He was doing straight angled panels not the other way of doing it on
the TS, which would have meant even more sanding

I made 18 raised panels Thursday night. One pass each, no burn marks,
and about one minute sanding on each. I made a quick and dirty jig
consisting of a piece of plywood screwed to the fence to give it some
height, and a piece of plywood screwed to the mitre gauge. Set the the
blade height to 1 3/4" @ 5 degrees. I think the most important part is
having a decent blade. I use a Forrest WoodWorker 2. If you like, I'll
post a pic of the jig on abpw.

Try using a scraper to remove the burn marks - quicker than sanding plus to
will leave a better finish.

Thanks, Rudolph. I made what sounds like a similar jig. I'd like to
see yours so if you would, post it to apbw. I'll post mine there as well.

I, too, have a Forrest WoodWorker II. I was doing my angles at 14
degrees with my blade set probably around 3-4 inches which may have made
it tougher for me, but I am going to send my Forrest blade in for a
fresh sharpening before I do it again.

Thanks.

These can cause burn:
Dull cutting blade
Feeding the wood too slowly
Using wood that is especially prone to burning (such as cherry)

Nothing that I know to put on the blade to reduce burning.
