Using Cement Blocks as Blocking?

[Dave5Cs]

I use these but on piece of plywood so no slipping on concrete but wood blocking on dirt or gravel.

Dave those don't look bad for the price either,mine have a larger foot print,a little taller and heavy as hell,lol I wish mine weighed  less than 1 once like in Amazon specs for that set,I want a set of 12 ton OTC 1778 B if I ever find a set on sale

Personally, I like using a table like this to set my bus on when I go underneath. Just saying'.

Lords way of weeding out the stupid.

Serious question...  I have some leftover 6x6 rough cut cedar from a pergola project.  Is that a good material for blocks?  The reason I ask is that, in working with it, I noticed some pieces are much more dense than others (at least by weight).  So, I am kind of concerned that a less dense one might not be as good for blocking.

Cedar is a soft wood they are not much good for cribbing

Hemlock is good. Evergreen, but grain is similar to oak.

Any wood in satisfactory condition, ie: no rot nor degrading of any kind - is okay for blocking and cribbage as long as it isn't point loaded. The use of steel plate to spread the load enables any type of wood to be use except for balsa wood or any wood with such weightless & light characteristics. Cedar was used as structural construction lumber in earlier times, same for redwood and other light soft species. We use PT pine 6X6 & 8" round in the vertical position with a metal top plate as the grain direction makes it much stronger with HD SS band around the circumference for added security in case of cracking or splitting & steel plate between it and earth. Hemlock used to be the conifer wood of choice for structural construction lumber but it's now pricing makes it prohibitive. Newer hybrid wood species like SPF (spruce/pine/fir) are predominantly domestic construction lumbers then there's a flu of exotics (foreign) out there. I'm no expert but carpentry is my trade and in my millwrighting experience with heavy hauls and setting heavy equipment - wood is a fine cribbing and blocking material when used with good common sense.

At Tenneco or safety guy Burns specified oak only for cribbing some of our vessels and compressors would weigh 150 tons and we may have 50 miles of 30 inch .250 wall pipe cribbed on 4 x6 x 4 oak waiting for trench.Oak was easy and cheap to find in Texas we used it to shore deep trenches after Burns would give classes on cribbing and shoring, lol the friggn yellow pine in Texas is hard as oak is was grown for paper mills in Texas

Oak is heavy Clifford.  I was going to suggest Balsa. Just kidding.

Yes it is I would watch the labors unload truck loads of 6x4x4 we called skids then when finished they loaded all the skids back on trucks to go to a section of new pipe line construction,welders had no problem going under pipe cribbed up to weld the bottom of the 30 inch pipe 2 ft off the ground ,they would bitch a little if it was over 2 ft

They are nice stands but the price is always high for jack stands

[Jim Blackwood]
