CMP jack blocks
Recent discussion of Carrier jack blocks prompts me to post this photo of the wood jack block supplied with CMP's. This 10" X 10" X 1-3/4" wood block is marked C01Q 17082. Usually there is distortion or de-laminating of the wood over time..... Brian

Am I correct in assuming that it is made of 3 layers of hardwood stacked and laminated with grain running perpendicular to the adjoining layer? Are they commonly available or should I just make up a few for my trucks?

Grant,
I have seen two types of construction. One type is basically a 10"x10"x1 3/4" piece of plywood. This is the type that suffers de-lamination of the plys. (Brian may have detail pics of these) The type in Brian's picture is essentially a 10"x10"x1 3/4" hardwood block that has a 5/8" wide x 15/16" groove cut into the end-grain. This groove then has a 5/8" x 15/16" x 10" piece of wood glued into it to discourage warping of the main block. Attached you should find a couple of picture. Unfortunately it is dark in the shed and the pictures were taken with a flash. Colin |

Thanks for the extra pictures Colin, I see now that what I thought was 3 layers with 1 chunk delaminating out (in Brian's picture) is actually the extra piece inserted to prevent warping. It makes perfect sense now and I think it should be easy to replicate for my needs.
