Hey just copying my youtube comment… get the feeling you don’t pay attention to those, which is understandable!
Quick comment about the portable 2x4 clamps.
Woodworker here. I’m guessing you’re not who I was thinking about -it’s not generally meant for but, … feedback!
The heads on your clamping surface will bite into material, mark it up. It’s also kinda small and far from the 2x4 which means it may bow the material (without much option for control). I would prefer optional heads that you could swap in like the heads on something like:
“Bessey K-Body REVOlution Parallel Bar Clamps”
-for example.
The larger surface allows you not only to spread out the clamping load, it allows you to position the material in or outwards to bow the material in/out as you go. Each subsequent clamp might counter the bow of the last one. It’s hard to explain but, the point is: Optional alternate heads to the small round ones you offer there would be a nice upsell offering.
again.. you’re a metal fabrication guy here but, you could apeal to a larger market here if you like.
