ENGINEERABLE

The Mercedes Sprinter Van transmission is a bit weak for such a large vehicle. It works, but it could use a more heavy duty transmission. I'm speaking specifically about the NAG-1 transmission. One of the issues is keeping the transmission cool, especially in hot weather and when fully loaded, towing, or going up hill. The transmission fluid passes through a radiator, but the cooling air is preheated by the engine radiator. This is good for cold climates, where the transmissi

Since the van doesn't have leveling jacks, parking on a non-level surface results in sleeping at an angle, which can make it very difficult to sleep. Therefore, I designed the second iteration of the bed to have the ability to adjust the angle in both directions. The bed is attached on one side to 2 vertical t-slot rails on the wall.

Although we can tap parts on the HAAS CNC mill using rigid tapping, it's often quicker to hand tap parts vs setting up the code and fixtures, especially if it's a part that we are not already CNC machining. So we needed to find a tapping arm. Tapping arms traditionally had air powered tapping heads, but there are now many relatively inexpensive electric tapping heads that have much more programmable options, and don't need air, which is loud and inconvenient. The electric tap

I've needed a cordless extended reach ratchet/socket wrench to save time when working in hard-to-reach places. The Milwaukee one with the low-profile sockets is sweet, but I can't justify the cost for occasional use. If I were using it daily for my work, then it could be worth the investment. Dare I say it [Harbor Freight] actually has a good 12V Cordless 3/8 in. Extended Reach Ratchet sold under the Hercules house brand. They also have a 1/4in version. The watcher looks nice
