This post goes along with my Clamps and the question of how many clamps should one have in their shop? I mentioned that I was building my own Bar clamps as well as purchasing them from the store. Well here is the videos of where I got my Idea as well as the plans to both a Bar/Pipe clamp and a Parallel clamp. They were only two dollars each and well worth it in my opinion. You can purchase these plans from his Website. This is not necessarily a tutorial but its showing that anyone can build these. I am not completely done with them but I am very close.
Shop made Bar/Pipe clamp
Shop made Parallel clamp
Here is a picture of some of the tools that I used. I also used a Drill, Drill Press, Table saw, Miter Saw, Combination sander and Band saw.
I spent some time trying to find the pipe to use for my clamps. I ended up finding it at Menards for around $10.00. The outer diameter is roughly 29/32.
Every store but 1 that I went too was out of this threaded rod. I found it at Sutherland's for $17.00
The hardest parts for me to get were these little brackets and I have yet to get the grips for the handles. Luckily I had a co-worker who has a metal shop at his house. I only needed 4 but I had him cut me a total of 12 so I can eventually build some more clamps. As for the grips which you can see in his video, I have not purchased yet.
You will need lock nuts and standard nuts. The washers I purchased at first were a bit small so I purchased more that were a bit bigger in the outer diameter.
