Not My Conical Disk

Sand paper installed may effect the reading some but not that much.

is it possible there is a bubble or high spot right there to affect the reading?

Mine is not either, but does it matter as long as it is still conical? As you have shown, you set the table using a square. If necessary you can make adjustments to the table angle when using the jointer/planer knife sharpening jig. You might already do this if you want a more acute grind on the blades.

Yes, that is certainly possible but there is no bubble. I have checked this without paper installed and get the same reading.

From the very beginning there has been some confusion about whether the conical provides a 3&#176]it here[/URL] for yourself. About 5 minutes in.

My conical disc is also just shy of 3-1/2°. Wixey just resolved just how shy. Where this comes into play is obviosly setting the table angle. I use a square to set it perpendicular the actual angle. If however you setting the table based on an assumed angle of 4°, it would be wise to verify it.

It ain't 4°! It is 3+°. The dimensions of Nick's thickness sander jig in a saw dust session ends up at about 3.2°.

Why SS insists on perpetually calling it 4° is a mystery(or they be like an ostrich).

Accept it! That IS the way it is! Use square to set table, and move on!

I also corroborate the conical disc NOT being 4 degrees. I didn't try my Wixley, but my gauge under table is set exactly to 0, so I just counted back 4 lines... I'm assuming, of course, that this gauge is somewhat accurate.

Regardless, I was getting a setting at a little over 3 degrees. When I tried 4 it was very easy to see that the results were not square.

That is why I have come here!! LOL - to see if I was doing something wrong. It was my first time last night using this thing. And WOW - I love it... I just had difficulties setting it up.

I'll have to measure out further on the edge of the disc. I tried USING the outer edge and it was burning the wood - I even slowed down the disc more.

no Swirls - but there are slight "lines" like a belt sander might produce. Maybe there was some pitch or resin stuck in there - or an imperfection in the paper. It was NEW however.... Anyway - 5 swipes in my hand with some 220grit and they were gone.

Also on a side note - If I take off too much stock - a LOT of dust is created and it totally doesn't go in the vacuum shroud!
