Tool Tips: Mini spring clamps, create your own thermocouple clamp, swaging tool
While working on residential furnaces and air conditioners with door switches, I find it useful and cost-effective to carry a miniature spring clamp in my tool bag for diagnostic purposes. There are many options on the market utilizing magnets; however, most are not universal or claim to be and never quite work out in all situations. The mini clamp (less than $5 retail) is an easy addition to any tech’s tool bag with endless capabilities, and [it’s] guaranteed to hold until your troubleshooting is done. The other upside is that you can use it to clamp your thermocouple on a line-set or use it as a flashlight holder. What a multi-tool!
