Ive been thinking of making better butt clamps for an upcoming project... Read about it here https://www.jalopyjournal.com/forum...ng-clamps-with-a-twist.1172899/#post-13320692 Took some ideas from some members and came up with a prototype. If theres enough interest I can do a step by step build.. It took me like 4 minutes to build and about $1.50 Yes its spring loaded
Does the spring stay stuck inside the tube to ease the job? If not maybe a glob of formagasket would keep it there but let it sproing.
Make the little cappy thing on the end of your tube have wings so you can press the plunger in just like a syringe, one-handed. (I bet you are already working on that version as I type this)
