The Magnetic Filtration Cover
​In 1995, I designed this cover for U-Haul. I was rebuilding all their differentials The vehicles were driven hard. The only thing I could control was oil changes and removing the metal contaminates as soon as they entered the oil. So, I designed a cover that can monitor the oil, Collect all metal particles on magnets behind a viewing window. I also installed a drain plug, Temp. sending unit port and a higher fill plug.
The Ford 9in. Cover & Weld-on Adapter ring.
Gerald Williamson and his wife Gloria. They were like my Mom & Dad. I met Jerry in a business meeting. He was so humble, but so knowledgeable in so many things. I asked, How do you know so much? Who are you? He just smiled and over the next 10 years, He taught me about design. He always said, "Keep it simple, yet beautiful". Jerry designed the Ford 9in. Cover. It was elegant, yet simple. Thank You Jerry. As I met their children and grandchildren, each one unique and brilliant. Each one raised the bar and set standards in their industry and sport. I am proud to know that family. Jerry and Gloria passed on now and I miss them deeply. I still find myself wanting to call Jerry to discuss a problem with something I'm designing.
The Ford 9in. "3 in 1 Insert"
The Ford 9in. has a oil flow problem. As the Ring Gear turns and throws the oil forward towards the pinion area, I hit a ledge at the top of the housing. That in turn crates a water fall affect and reduces the flow . I designed a bolt in device that fills in the upper part of the housing and improves the flow. I realized that since I had flow, Why not filter and direct it over the carrier bearings. This design proved to be very effective in filtering our metal particles and improving oil circulation.
The "Off-Road Creeper"
The "Off-Road Creeper" was in the making since I was 16 years old. I was on a road-call along the highway. It just rained and I forgot my creeper. There was a dirty old garbage can lid near by. I grabbed it and laid in it. I started to pull myself under the truck. WOW, WOW, WOW! It slid so easy. I never forgot that. Well 10 years ago, I started making my fist sliding creeper. I soon found the polypropylene was the only plastic that would work. I designed and redesign the creeper so it would perform many functions. 1. It allowed your body to be close to the ground. 2. The rougher the surface, the easier it slid. 3. The metal discs located at the top allowed the mechanic install magnetic lights and/or tool dishes. 4. It was thin and can be stored behind the seal. 5. The holes on the sides worked as handles, 6. Holes at the bottom allowed a rope to be tide and pull the creeper. with an transmission on top of it. 7. Hole at the top, You can hang it on the wall. It will be ready for sale in March, 2025
Easy to make Front Differential Tube Cleaner
I always get front differentials that have a lot of mud, sand, or whatever inside of the axle tubes. So I sell a service that taps the spreader holes on straight front differentials. I provide the customer a photo of all the pieces they can get from a hardware store. Now when they go mudding or playing in the sand, they can wash out their tubes at home. When finished, just remove the washer and screw in a 1/8" pipe plug.

Other Tools I've designed .
I have designed so many tools that I use daily in my shop. I'm not going to manufacture them, But I'll be producing videos on " How to make your own. I designed an air pressure oil tank that I built from a Propane Tank. Hydraulic presses. Transmission jacks. Mobile shop wench. A swinging/rotating Electric Hoist. A Press for straightening housings. An Attachment for your forklift to move vehicles.
