I have a sheet metal joining application that tog-l-loc process will work well on and I'm hoping somebody is familiar with and using the system. Their website is good but nothing beats experience.

What do you want to know? Whirlpool uses it to hold a refrigerator together as well as several other large manufacturers. Works better that spot welds IF you don't have a bunch of vibration. R. Wink
I want to hold side plates on wire wheel brush sections, 19 ga. CRS. The plates touch in the center 2 inches sandwiching a brush section between them. I want the loc's to be as close a step in the plate as possible as this would be the limit as to how big of an arbor hole I can punch. The step is about 1/8" deep with a 2" dia. From the website, it looks like 3 or
4 loc's will do. I don't know how big of loc's to use or how big the die insert is as to clear the step.4,6mm / .18" Tog-L-Loc® Punch Side Metal Die Side Metal Shear Peel Report Thk inch Thk mm Type Hardness Thk inch Thk mm Type Hardness Lbs. N Lbs. N No.

Peel is something else. You might want to submit your design to BTM for them to run samples and to do peel and torque testing for you (I think it's free, IIRC) The PDF data sheet
Thanks! I wanted to get a projection welder but my power company wants $20k to run a new 880 and says that it would sag my current line as I am at the end of a run. They're not happy about a new welder only gulping huge current for a few cycles and they won't make any money on it. So, a mechanical bond is the answer.
