I am looking at building some blocks to set my car on while I do the tranny fitment for the cross member and other stuff.
I have seen the ones you suggest out of 2x4s, I am thinking of making them out of 2x5 tubing from scrap at work.
I was just wondering what height works best,
I want it up where I can work but not to high either.
How tall of blocks would you suggest?
you really need about 22"-to-23" clearance| measured from under the frame to the floor to easily use a creeper and remove a transmission,
or easily change a clutch or change oil, if the car or truck ground clearance sitting on the pavement is lets say 4" currently,
ID suggest the under the tire support column is 24"-that 4" or 20" tall under the tires,
if you have 8" currently, than 24"-8"= a 16" stack height

buy 8-10 8 foot long 2"x4" boards cut into 15 7/8" lengths and some good wood glue, and 4 16" square pieces of 3/4" plywood that are used to make sure each support stays square, plywood square placed mid stack, with 3 2x4s in each layer of the stack except the top where you use only the outer two, to prevent the tire from rolling off the stack,this will result in a support column about 14"-16" tall under each tire,
be sure, you use good water proof wood glue, and allow it to set up over nite, before using the support stacks, and painting at a minimum, the bottom surface so it won,t absorb moisture is a good idea and a few dozen 3" wood screws
this will give you 24 sections for each support for less than $40
I generally keep about a dozen 16" square pieces of 3/4" plywood I can use to stack under my jack stands on asphalt drive ways, when I visit a friends house because jack stands don,t play well with asphalt drive ways in florida heat,(you get about 15 out of a sheet of plywood and home depot will frequently cut a sheet into squares cheaply or for free) these can be used to shove under the 2x4 support stands to vary the height on un-even or inclined ground
I have built several sets of those under the tires support stands from 2x4 and pieces of scrap plywood Ive salvaged from construction sites in the past, but generally found I have donated those to someone ,as they only cost me time and a couple bottles of wood glue and a few dozen 3" deck screws as I own 6 of those harbor freight 12 ton jack stands
as to swapping a trans and the required clearance under the car.. the clearance will vary with the car, mechanics creeper height, tire diameter and your belt size, this thread might be useful- while I try to buy American made products you would have to be very un-observant,
to not have noticed that the newer HF floor jack quality has improved drastically from several years ago, and they come with a decent warrantee..
