I think there was a post a few years ago with a link to a site that described how to make a long level from MDF and a few adjustable screws. Can anyone direct me to such a site?

Thanks

It's possible to use a plumbbob and midpoints on a sheet to make a level. See if you can figure it out from this picture:

You can use 2 squares one on each table and they should mate over the knives. A jointer has to be well set up to be a useful tool. Your out put will only be as good as the input.

Why would you need a level to set up a jointer?

A long(ish) straightedge and a set of feeler gauges , that's all you need ...

I concur with John Hall and two squares...........with the warning your squares have to be accurate. All squares are not equal,just make sure yours are 90 degrees.

Thank you for the correction (and the other ideas, too). I meant "straight edge", "not level".

The article I saw before used something like a six inch by four feet piece of MDF with a trick to put in bolts on the edge and get them lined up exactly. It was a really simple trick, but it slipped my old mind. I think it used two boards as mirrors of each other.

Todd, I think that was the method I was referring to. What is the use of the six inch ruler?

Thanks.
