GRR-Ripper type Push-block
I wanted to rip some really thing strips and I had no pushblock suitable for such cuts.
The GRR-Ripper is well known and how good it is, so I thought to try build a similar pushblock that could handle the job.
This is my prototype made out of completely scrap pieces that ended-up working nicely and me regretting that I didn’t build this with better materials abd nicer… :( but I can always come back and do it again with some slight changes in its design.
For T-tracks, once again I used aluminum curtain tracks, and a couple of aluminum angles.
For an anti-skid grip, I used that 3mm “Ordex” non-slip mat (this material has such an awesome grip).
Anyway just keep in mind that this was a prototype but that ended-up working just fine, and please don’t judge me harshly on this project.
Center top: 10×20cm (4”x8”) and wood thickness 2.5cm (1” 1/4) you can adjust the wood thickness according to what t-track you will use, just leave about 4cm (1” 19/16) inside height space.
Also you can build this from thick plexiglass (2 pieces).
Sides: Left side 12mm (1/2”) thickness and right side 6mm (1/4), both will have threaded inserts to accept the stabilizing plate so that you can use the push-block from both sides.
Center Block: 20cmX3cm (8”X1”1/4) height 4cm
Stabilizing Side Plate: 20cmX10cm (8”X3”3/4) Wood thickness 12mm or 18mm (1/2 or 3/4)
I have uploaded a Sketchup file for your convenience: DOWNLOAD HERE
