No! Those Clecos need a hole which would need filling and are used for lap riveting. Waste of time and money. The were invented for riveted assemblies. A 1/8 rivet hole is the same size a cleco wants. Aircraft and aerospace riveters use them. I use regular welding
clamps. Magnets, tape, vise grips. I used to use
these but I don't anymore. Many times there is no access for them. If you use them, you can grind down the blade for a tighter gap.
I want to say that guy has a good idea on how to hold parts together but I can't. All he as to do is lay the parts down and butt them together with his glove hand and tack weld them.....or use the other holding methods I listed. Very, very weird presentation. He holds the two parts with his hand when drilling. He cuts the super scribe line with tin snips and I assume he is going to drill three holes in the other piece to reattach the clecos? Maybe there is a far reaching "collision repair guy" reason for all this that I don't see. I would never do any of that.
If I was going to buy any more holding tools, I would buy from
this series of tools.
