I saw the Rockler one, but did not mention since you said you wanted to purchase. I think Rockler intend you use one of these each side, and the price is for one.
Thanks Dave, I've been thinking about it and I'm pretty sure I can make one now that I know exactly what it looks like. I could probably do that with a small cheap 'C' clamp from Harbor Freight. Just drill and tap a hole in it for a wing screw and I got one. :smile:
I think you can make one. If you are only looking to push the fence, then consider a connector nut used to join two sections of threaded rod together. About 1in long, easy to clamp under the "C" clamp and save the time of drill and tapping.
If you make a U shaped box for behind the fence, you can have the threaded rod go through the bottom of the "U" and then drill a small hole for a cotter pin with washer behind. Lock nut on the other side and now you have a design which can pull as well as push. If you are not picturing this, it is the same idea as how the handles attach to a Black and Decker Workmate.
I was going to do a sketch then decided on a quick prototype.
The Jharris2 style is easy, but it will only push the fence forward. If you push too far, then you have to unscrew, reset the fence and start to push again.
An alternate design is to be able to push or pull the fence. This needs the threaded rod/screw to be able to swivel at the end.
I mentioned a "U" to hold the end of the threaded rod/screw and allow space for the swivel. A very quick and easy swivel. Not pretty but functional.
This is a piece of scrap from the shop. Imagine this is one side of the "U".
I drilled a 3/32in hole in a piece of threaded rod, an offcut from another project.
I use a small hitch pin in the hole and a washer behind the hitch pin.
On the back side I used two nuts tightened against each other. The nuts would be adjusted to minimize slop/backlash, but not too tight since we need the rod to swivel.
I am showing a connection nut, also called coupler nut, just to provide more area for clamping or gluing.
I added a lock nut at the end. This is a nut with a plastic collar. Showing a rachet wrench in lieu of a knob.
I hope this helps you understand the suggestion.
