Surface Grinding Attachment

[JKeetonKnives]

As a knife maker, I love having flat pieces to work with. Makes my life way easier. In this video we will be replicating a common design that was first pioneered by Travis Wuertz. The Parts list and some drawings are in the description of the video.

Hey guys, I wanted to put this here as a follow-up if anyone happens to find this thread in the future. The SGA has been working great for me since February! THis update video has some tips and tricks on how to use your SGA if you're going to build one.

Cheers!

Way cool!

A thought on the adjusting knob:
Use a differential screw.

You can take a 3/8-24 screw, thread it through a block, and have a 1/4-28 step-down on the end that threads into the plate holding your magnet.

One full turn of the screw = (1/24) - (1/28) Inches, or .0416 - .0357 = .0059"

I have an old block plane with a differential screw on it and it's really nice for tweaking the cut a tiny tiny amount.

Of course, if you can cut your own screws, you can make the final amount be ultra-tiny.

Another way to get finer movement is to use a lever action to press on the magnet plate, using a spring to pre-load it back against the lever.

Your adjusting screw pushes on one end of the lever, which is pivoted (say) 5" away with a 1" extension past the fulcrum/pivot point. This gives a 5:1 reduction in movement. So, a 1/4-20 screw (.050" per turn) will make a .010" movement.

Of course, your total movement is then restricted, so you'll need to add a rough-adjust slide to this structure so you can get close the right measurement, then use the fine-adjust to do the final moves during grinding.

Just some ideas to keep you up at night!
