The last two posts about pipe fittings were new to me, but I should have known Mcmaster would sell them and at an awesome price. See page 1580, speed rails.
My blog is going to be a bit of an addition to my site Fightraining. My main how to make articles will remain there and be added to there. I'm hoping the blog will allow me to update things quicker. The blog will be mainly about interesting workout stuff I find on the web, brief descriptions of new homemade projects, my fight with diabetes, and occasionally other interesting things I find on the web.
