Offered up for your review is a push block I am making for my brother. I first saw a version of this in “Woodsmith eTips”, an e-mail I get from Woodsmith Magazine.
In picture one you will see the push block with the slide stick in an up position, and the turn screw out. Also in the picture you see a replacement sole and heel for the bottom of the push block and two extra slides.
In picture two you will see a side view of the push block with the slide down so it is able to contact and push the piece of wood to be ripped, the turn screw in, holding the slide in position and the extra replacement pieces.
In picture three you will see a change I made to the original push block plan. Now you can trim and replace the sole.
You can see by my old push block how torn up the bottom of the block gets. There is only a sliver of material left to actually push wood through a rip cut after using the old one for a while.
When the rectangle of plywood is attached to the new version push block, you have a parallel edge so you can run it through the table saw and trim the sole of the push block back to a solid surface. The new sole and heel can be glued in place.
As the slide is worn, it is repositioned lower until a new one is needed.
The slot is produced by gluing a sheet of ¼ inch plywood to each side of a piece of 5/8 plywood, leaving a groove for the slide stick. A “T” nut is captured against the rear or smaller side of the slot to give thread to the hole the eye bold uses to secure the slide stick.
I think it should last much longer than my old version push block.
There is a feel of control to this unit. I like the slant to the handle. I have had a push block kick back at me before. I had been using a stick with a squared off handle. The impact made an “I” shaped cut on the palm of my hand and hurt all the way up and through my armpit. This handle would just exit instead of exit with prejudice. (I did sand it so as not to give my brother the largest and deepest splinter ever.)
