That is magnificent!

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 farm boy design.

Thank you! Lol, l do appreciate the compliment. I am a retired Electro/Mechanical/Structural Engineer, so that might have given me a slight advantage. When, l have time, l will provide more details, and pictures. I basically built this on the same premise that you built yours, only l made it for myself. I am disabled, and have a Hoveround power chair, that clearly has it's limits, and refuses to do much of anything outdoors. I like to putt around town, other than in my car, so, l figured.....l'll just make my own offroad capable high speed piwerchair. Right now, it is patent pending, and l plan to sell them to disabled people, kids, or whomever just wants one. Believe it or not, l actually get stopped all of the time, with compliments, and questions. Bye the way, l am impressed with your "farm boy" design. Good job!

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 look forward to reading all about it, soon I hope!

Default 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 fabrics, canvas drop cloths, and just about any fabric, woven or not.

Then they coat it, and saturate it with paint, varnish, glue, resin, or whatever they have on hand to try that will dry and hopefully glue the fabric on and harden up.

I have some epoxy left over from other projects so I mixed a bit of it up...

And covered this:

And this is the fabric I used:

Tonight I will trim off the excess and see how well the fabric worked.

I have about 275 ft(!) of 42" wide 4 oz fiberglass cloth left on the roll I bought a few years ago but it is up high on a shelf that requires ladder access and it is heavy. If the PMF isn't good enough I will climb up and get it down to cut off a little piece to bond over the weed fabric.

Or maybe I should see what cotton cloth Robyn has in her sewing room that she has no plans for?

All good fun, eh?
