I’m looking at THESE

To use in place of traditional knobs in my easel building project (that I haven’t started yet because I’m ripping out my kitchen floor and redoing it…. laminate sux in a kitchen). The cam clamps would need to hold pieces that slide to hold a canvas. So in the following picture, I’d be replacing the knobs with cam clamps. Would they have enough holding power without being too hard to operate?

I have purchased several sets of these and have not been too pleased with the outcome. They didnt work too good in my applications. I ended up having to install a “o-ring” along with the supplied rubber washer to help increase the cam holding power. Wish I would have bought knob style clamps instead. Just my 2 cents worth

good information. Thanks. I’ve never used them. Was interested in hearing about first-hand experiences with them so this helps a lot. Thanks! :)

I’ve not had real positive experiences with cam clamps of various sorts. The tension can sneak loose and flipping the lever doesn’t lock down as tight as you expect. Things move. I’ve had cam clamps that pop open when what they’re supposed to hold moves.
If you were building this of hard wood, I would suggest a holdfast type of compression. But, given the situation, knobs are by far the most reliable because every time you use them you become aware of how tightly they are holding. You can make your own with turn buckle type of handle very quickly and efficiently.
Simply a 3/4×3/4 stick cut at 45 degrees every few inches, hole bored for bolt, counter bored for hex head and pressed into undersize hole. Carriage bolt can be left on surface. Making your own allows you to choose the wood and mix or match colors. These are as strong as any plastic knob!

My only experience with cams is on the Leigh D4R. They work okay in that application. I don’t know how much torque you need to hold your canvasses in place, but I can imagine that a “slip” might ruin your day.
