Build your own dog leads of wire from TSC with a crimper deal??

Could you post a picture of the tubing, i never seen one made with the tubing so far, where did you buy the tubing?? Does it come in different colors?? I see posts about different colored leads?? Are you guys buying different colored wire cable or buying clear cable and then slipping different colored tubing over it?? Where can i get some colored tubing?? Thanksa again for teaching me all of the tricks. I know I wil get this down soon, on the way back to CC to get the correct crimper and different size ferrules. I have a welding cable maker that you strike with a hammer for different size cable leads and usually make battery cables for dozers and graders macks etc, think that might work on the larger size 3/8 wire cable?? I going to try to dig it up later and see, i like the idea of making your own crimper with the old bolt cutter by grinding, i got one that mite work.
