Prior to wine making, my main hobby was restoring '60's era cars. Mostly Fords and British sports cars. When we bought some property 2 years ago, I sold my 3/4 finished project car (Sunbeam Alpine with Ford V6) so I could focus on getting the property and the vineyard back in shape. With 4 grandchildren, I wanted something that we could putt around the property in, so I made a mini-jeep out of a riding lawn mower. To say that it has been a hit with the grandchildren is an understatement. They love riding in it, but the pedals make it so they won't be able to drive it for quite a while.

I want to do a follow-up project, one that the kids could easily drive by themselves. I've decided to make a mini Army tank. This is what I am using as the basis for this project, which I picked up 2 days ago. Some definite hurdles to overcome to use the drivetrain for this project; traction, ground clearance, uneven terrain, enough torque?

The unit is fully operational and I can tell has little use. It was a bargain @ $100. I stripped it down and wanted to convince myself that this was a good idea, before spending more time and money. While I would love to have it a track driven machine, I don't think I will go through that level of effort as the time/cost vs fun ratio probably isn't there, unless I have to do it to make the whole project useable.

The stripped down buggy is pretty fun to drive, I think the grandkids will have a blast. Plans are to get the mechanical squared away first. It will need new batteries and off road drive tires. I'm hoping I can get away with the front/rear tires as they are. If not, I am prepared to re-engineer it so is can navigate flat grass.

I've learned more about wheelchairs in the last few days than I thought I ever would. I was looking for a chair with a big wheel (14") because I knew it would be needed for traction. This had the unintended benefit of a chair that had bigger motors and batteries and this model in particular has coil-over suspension that will allow me to do some ride height adjusting. Besides a very expensive 4x4 wheelchair or one with tracks, this Quantum Q6 model ended up being the perfect choice...assuming it all works in the end.

Oh, you'll have fun with that! A story I wrote...

I found that Honda 50 Monkey off road knobby tires will fit these rims and the rim can accommodate an inner tube. The Honda tire is a half inch wider and a little taller, so some spacers and fender modification or removal are probably in order. I removed the lug studs to find ones a 1/4 longer. Amazon should deliver the tires and tubes tomorrow.

I could pretty much tell when driving the go kart around that it was struggling when under load, like going up hill. I measured the voltage of the two batteries, one was 12.7, the other 12.4. I took them to the local auto store, who can test them under load and they both failed. Ordered $218 of new batteries via Amazon today. I expected this expense, but happy I was able to test everything on the chair first, before spending $ on the batteries.

While waiting for parts, I was looking at the new tire fitment issues. I couldn’t find longer studs that were the same width and pitch, but longer and it would be best to not use spacers. I ended up removing the fenders and the top deck. This still gives me a good base, lowers the center of gravity and should resolve any clearance issues.

New batteries made a world of difference. The thing scoots pretty good. Still looking for spacers and studs so I can upgrade the tires. Passed the test to move on to the body build.
