When I built my outfeed table (all previous versions), I used the vertical support tubes for the reference. Whenever I tilt the tables I experience the moving trailing edge of the outfeed table.

Dusty, I was just going through the Hands on Line videos and found this one
SS120--Ripping Bevels with a Tilted Table where Nick and Drew show how to modify the outfeed table to correct the geometry so it stays true with the main table when tilting. Looks like a simple fix. Also includes other improvements that can be made to the outfeed table.

Edit That link is now broken, this one will work Ripping Bevels with an Outfeed Table

Interesting.
Dusty says the piviot offset is 5/8" but in the video Nick says they moved the piviot 1 1/2" on the outfeed table to keep everything in alignment.

Nick and I both made adjustments to correct for errors that each of us made but we had not made the same error. Therefore our corrections were different.

We were both attempting to create a pivot point that was in the same vertical plane as the Main Table pivot point. I did not get there and I don't know if Nick did. I cannot tell by watching the videos.

My 5/8" difference seems to cause about a 3/4" sag at the outfeed tables' edge when I tilt the Main Table. I have incorporated a fix that in effect lengthens the diagonal table support leg.

Not an apples to apples comparison. Nicks pivot was held between two threaded inserts. Nick moved the outboard insert in the stock table to become the inboard insert if you will.

RonD, I hope you can think of another source for that vid. Blip no longer hosts that, and I can't find it in ShopsmithHandsOnline vids on YouTube.

I have been reading up on the OFT adventure/experiment and now I'm eager to join the crowd of happy outfeeders... but if I can make only one version, and can avoid the canting at extreme angles, I'd be happier. (Sort of similar to the reasoning behind no longer buying green bananas.)

Cheers!

After much head scratching and wasted time on tangents, it was determined that a simple detail eliminates all canting.

Make sure the outfeed table pivot aligns with the main table pivots. Then they tilt harmoniously.

When that is done, the location of the lower end of a support arm becomes irrelevant.

The table tops must be in the same plane as well.
