Now that I've strung a grand total of one tennis rackets, I feel entirely qualified to write this post and tell the internet the necessary pieces one should ensure a stringing machine (glide-bar style) has before one purchases said machine. Obviously, the above was sarcasm. I am not very qualified, and any advice you take here is advice taken at your own risk. Anyway, on to the advice. Please enjoy this lovely diagram with some very official labeling: If you're looking for a glide bar machine and it has all of the pieces you see there, you're probably in good shape!
Personal projects and retrospection.
