Fun-Tak aka Blue Stuff

It is often neccessary to hold parts and sub-assemblies firmly and accurately in position before soldering or gluing. Using the soft blue substance known as Fun-Tak is an excellent way to accomplish that postioning. The putty like substance has enough tack that it adheres well to most surfaces and yet is easily removed. It is a LOCTITEŽ product and is sold by most hardware stores and large chains. I buy mine at a large store whose name begins with a W. Below are pictures that detail several methods of use. It's very easy to employ, so give it a try if your next project needs a third hand. Do whatever it takes to stabilize the part, this stuff is great. DucoŽ has a similar product called Stik-Tak.
