We've had a number of people email or comment asking for a tutorial on how to build pulling blocks. I'm not going to do a full-blown instructional article, but I'll cover the important details quickly. First, the basic construction is the same as our jerk blocks, which you can read all about in this article
- stacking sections made, in this case, of 2x4s. The dimensions are 21" wide and 36" long. This is plenty big for even the most timid block lifters. The 21" width is also convenient because that's exactly the width of 6 2x4s laid flat alongside each other, which is what the top layer is. That top slab is simply connected by 3 2x4s running perpendicularly underneath. I later added a layer of 3/4" MDF glued and screwed to the top of the 2x4s under the rubber to strengthen it further.
The ones on each end are positioned to fit just inside the inner dimensions of the stacker below. The stackers have 4 cross-pieces: one on each end and two toward the middle. These are all connected with 3" screws, and on the corners, the same screws as well as a lag screw. I screwed handles on the ends of the top slabs for ease of changing heights and used leftover rubber on top. Overall these sections are relatively light and easy to move around. The bottommost section is screwed into a 3' long platform I attached to the full size one behind it. Because these were meant to be a permanent block station, this is a convenient way to make them more stable.
