I finally figured out how to use them. So, today, I cut a bunch of spacers for them.
These will be welded to an 1-1/2" angle iron. Then I will bolt a 2X2 angle over the top to keep them in place. Next I will drill another 2X2 angle for the lower part of the tine to go through. Use some imagination here folks as that hasn't been done as yet.
The spacers are 1/4" thick. The tines are .281". So by bolting another angle over them, I will "trap" them in place.
