Good blocks - be ready to take time to clean up
I bought these blocks to use in making set ups on my mill. I wanted to run 5/8" bolts through the non- threaded holes. Those holes all had significant burrs so 2 hours and several dozen sanding drums on my Dremel ... the holes are clean. I expected this for the inexpensive typical Chinesium stuff that it is. Now they are right and will serve me well in my hobby shop.

multi purpose tools
I use these to make sure I have square corners on sub-assemblies I make. I also use them as weights to help in the gluing process when clamps don't seem to work at all.I'm a model builder and I need a square joint vertical or horizontally and these are great in helping me make those joints.
