batteries Dad loves his Jeep and is exploring the neighborhood, getting lost, finding his way and pushing the limits of the batteries. Here he is heading out again after lunch: As a reminder, it uses (2) 24v Kobalt (Lowe's) power tool batteries to power the 48v motor. The 4ah...

Thanks! Thank you all for the electrical help you gave me. It made hooking it up and getting it going much easier. It is as finished as any project ever is. I will buy more batteries and I am quite pleased with the distance the little 4 AH gives it. I did switch the tires front and rear

Finished Project Saturday was the test drive to the lake. Everything works great and Dad loves his Jeep.

:cheers2: Exactly! I can figure things out and solve problems, I just can't remember how I did it later. :huh: I am always pleased when the engineers (here at work) do the calculations on something I have designed and I see how close I was on the steel beam sizes and other structural...

Easy! Hahahahahahahahahahaha :surrender: :roflol::confused: Simple, everything is either kgm²/s³, kgm²/s², or kgm/s² :wai: Uh, what language is that? :smiley_omg: Thanks for your help Sid, but I never had any teaching beyond basic math. I flunked 2nd grade because I couldn't read so I had...

Thanks Sid! :cheers2: The final results you figured out look great to me. :thumbsup: I don't know what that is written in some foreign language though...?:surrender: Chinese? Arabic? Hieroglyphics? Atlantian? Numerology? Egyptian? :huh: 165 kg * 9.81 m/s² * 0.02 * X m/s + 0.5 * 1.2 kg/m³ *...

Thanks Sid, the controller does have the three levels of power and I have a switch to choose between low and medium. My dad will most likely only use low and he says 5 mph is just right. That may change as he gets used to it of course, but the gearing should keep it slow for safety. The Jeep...

Paint! First coat of paint is on Primer: Flat black undercoat: Desert Sand (Flat) body color: Front end set in place to see how it is going to look: I put one of the headlight reflectors in place (not installed) to see if I like it. I think I will use them. They will be...

Minor progress I had half an hour last night so I "glassed" the hood, with out fiberglass. Have you read about PMF? That stands for Poor Mans Fiberglass where they use various fabrics and various liquids to coat objects prior to painting them. People use old Tee shirts, new cotton roll...

Excellent information indeed! I don't think it is only China made equipment that is often falsely labeled, it seems to be a worldwide problem. Buying from a reputable company is probably the best we can do to get what they say it is and what we are paying for. But even excellent companies can...

Shaping Last night I only had a little time but I did get the foam "hood" area shaped and ready to be glassed. Before: After roughing the curve with a belt sander: After hand sanding: Next up is covering the foam and then primer... paint... more paint... etc.

I do believe people stop you and want to learn about it! Patent pending is really something so I hope it works out well. You have a huge advantage with your training and experience, and that is why your design came out so well. As a user, you understand what others will want in a power chair. I...

That is magnificent! :wai: Please do post full details and more pictures of your rover. I would love to read all the details, why you did this and that, how it has worked out, and what you might do differently next time. Your machine is like something NASA would design while mine is like a...

Test pilot I forgot to post a picture of my Dad testing his new scooter out... It was -7F when I was zipping around on it in the driveway and street to see how battery life might be. Dad came out to try it but wouldn't put on a parka, or gloves, or a hat... so he got cold really quick but he...

I'm making slow progress on the body now that the mechanical is done and it works great. The latest pictures: I hope to have enough finished to start painting this weekend. :wai:

First ride success! I didn't go anywhere other than up and down our street, spinning donuts and sliding the one wheel drive on the packed snow. I rode it for twenty minutes almost continuously and at full throttle most of the time. The battery monitor had me at 25% for the last five minutes and...

batteries They are 24V 4AH so I don't expect the runtime to be very long. Hopefully long enough for Pop to go to the lake a block away and back. I may be able to find out later today in fact.

Oops I realized Friday morning when I put the pictures on my computer that I had installed the king pin/spindles upside down which will put a ridiculous amount of negative camber. :oops: So last night I put the wheels on for a couple pictures then took it apart to reverse the spindles. Now I...

First Night cont'd I don't use my angle drill/driver very often but when it is needed it sure speeds things up. End of day:
