Default McPappy Racing

We are happy to release our latest Helping Hands tool. The Helping Hands hobby vise was designed to hold small parts, models, crafting, hobby items, hold items for polishing, jewelry, circuit boards, engraving, wood burning, figurines / miniatures, soldering aid, fishing lures, art, watch repair, task lighting, gluing parts together, etc

+ YouTube Video
ERROR: If you can see this, then YouTube is down or you don't have Flash installed.


The 2 main components that make this third hand tool awesome are the 3 jointed articulating friction arm and the mini vise. 1 knob completely releases all 3 joints including the twist on both ends. A thrust bearing under the know prevents anything from wearing out. The stainless steel construction prevents the balls and sockets from scratching. It should last a lifetime. Each end has the industry standard 1/4"-20 threads that lets you directly bolt on other things. It acts like a desktop camera holder, desktop microphone mount, GoPro mount, or web cam holder.

For less than $10, you can also pick up other items to bolt on like a magnifying glass, crab clamp to hold things like a Dremel, cell phone holder, tablet holder. For a more portable solution, you can even get mini tripod legs, or even a suction cup mount if the situation calls for mounting to glass, window, or a kitchen counter top or similar.

This mini vise is the other component that makes this tool great. Featuring 2 polished tool steel rods, a custom turnbuckle with left and right-hand threads so it opens and closes twice as fast as a screw. The jaw opens to a generous 1.25". Holes in the jaws for the included steel dowel pins allow you to hold odd shaped items. The steel dowel pins open to 2.15". V-slots were machined into the lower vise jaws to hold straight items like screws and rods in either direction. The hobby vise was made from 7075 aluminum for 3 reasons. It's lightweight so it won't get top heavy with an extended reach. It acts like a heat sink. When soldering, this will prevent excess solder from wicking up the wire. Lastly, it won't scratch other metals. Machinists refer to these types of vise jaws as "soft jaws".

Default McPappy Racing Dyno version 2.0 for any scale - 2WD and 4WD

I'm happy to announce a project I've been working on for a while. The new dyno comes in 3 different sizes, 2WD and 4WD, chassis testing or motor to motor testing, 4 different load levels, built in flywheel, can simulate an entire race, and with Windows 8 or later, can even be controlled with your voice. This can accommodate anything from a small slot car up to some of the 1/5th scales. Custom sizes are also available

Do you guys have a version of this that doesn't involve the vehicle? Something to dyno just the motor only (brushless)?

Yes, we've made a few motor to motor dynos before. Check this out:

We've been thinking of doing another production run like the one seen in that video. Is that what you had in mind?

Yes. A standalone system that one could just tune motors on without the vehicle. I understand the idea behind the vehicle one however, just think it might be easier for me this way (as opposed to the vehicle dyno).
