If you want more flexibility and customization options, you can always make your own Loc-Line-style modular hose third hand tool (Instructables how-to). But, speaking from experience, it can be a hassle drilling and tapping a base plate.
Tip: You could also create a customizable vacuum hose setup using Loc-Line!
SparkFun’s Third Hand Kit is a ready-to-go Loc-Line-style component holding system. It comes with two flexible arms, two alligator clips, a drilled and tapped aluminum baseplate, and all necessary hardware to assemble it.
At $35, the SparkFun Third Hand Kit is a little pricey, but it is customizable, reasonably well built, and ready to use in just minutes.
The kit comes with no-name imported modular flexible hoses which actually aren’t flimsy at all. They’re not as robust as Loc-Line’s made-in-USA hoses, but they’re not bad either. Extra “coolant pipe” hoses can be purchased for $1.95 each, and extra alligator clip assemblies are $1.95 per pair.
According to the technical drawing (PDF), the aluminum base plate has (3) mounting holes drilled for use with 1/4-20 bolts, and (4) countersunk mounting holes drilled for use with common drywall screws. The 1/2″ flexible hoses attach to the base plate via (6) M14 x 1.25 tapped holes. This means you can attach up to 6 flexible arms to each base plate, and it also means that the base plate is not compatible with Loc-Line’s NPT-threaded hoses.
I purchased a complete kit when SparkFun had them on sale on Cyber Monday. I think the kit is slightly over-priced at $35, but there’s nothing quite like it commercially available. I definitely recommend it to anyone who doesn’t have the time or tools to build their own third hand system from Loc-Line components.
