Can't claim this as my idea as I saw it on the internet. I made this a while back but didn't add a handle to the push toggle clamp right away. So a few days ago I turned a handle for it. Everything you see I had laying around my shop. I used Hard Maple for the base and Red Oak for the turned handle. I added a t-track and rubber feet on the bottom. There's an adjustment block with a t-bolt and tightening knob that can be moved along the t-track for any sized pen kit. I used it to assemble the pens in the pics. It worked great.
