one of this years projects that did not get done
« on: December 31, 2007, 12:18:07 AM »
I've been gathering stuff from the side of the road for years, one of the things I never pass up is old bed frames, last summer I found some old boat seats in pretty good shape, I also pick up lots of bikes, and old mowers, last year I found 3 riding mowers, I brought all of it home, it sat around awhile and the plans for this project came to me while reading a popular mechanics issue that had a Rhoades Car pictured in the back.

I started the project on Oct. 27th.





The frame is made entirely from old bed frames, the front spindle's from a riding mower, along with the pitman arm and tie rod ends, the tie rods made from steel rod and threaded, the rear axle made using 2 old riding mower axles split at the differential, the differential is still there, the parts were just rearranged to put the differential in the center of the car.





The motor is a brushed 24vdc lawn mower engine that was given to me a couple of summers ago, I had got it with intentions of putting up a turbine, but the motor was to high rpms, it made it to a mower deck and I cut the grass with it a here at home till I killed the 2x17Ah sla's, I severely abused those batts, I did not have any meters on that mower to show me the state of charge, and I ran them way way down just about every time I mowed, lessons learned. Batteries are much better taken care of these days. The transmission from..... yep, Ridin' mower, 5 forward and 1 reverse.


The bike will get peddles on both sides, 3 speed using only the crank gears, the one way cassette's on the axle was cut from the wheel of a kids scooter, again picked up on junk day, The controller and all the switches and head lights and tail lights and horns and turn signals from the scooters will also be used, the seats are adjustable, and I have a guy who will sell me a bunch of 12v/18Ah batteries from those jump start boxes for $7.50us each, I have only spent about $60us so far, $30 for the wheels, I think they may had been made for a garden cart, or possibly a welding cart like they sell at Harbor Freight, they are way heavier than bicycle wheel, and had a 5/8in sealed bearing in them, and I spent $30us on a 24v wheel chair charger, And the guy gave me the rest of the chair with it, he said controller was bad, But I got it working with very little effort, thats next years project if the funds allow, It will become a r/c lawnmower. I'm thinking that 4 batts, with the $60 already spent and this will be on the road for a grand total of right at $100, depending on what misc. I still need and the paint and welding rod. I would also like to charge this with wind or solar someday. I'

I love it man, nice work. Ive always wanted to build one of those. Now I know better what to do when I see an used bed frame.

I love it !!! :-)

The price on those batteries are almost a Steal:-)

Most of those jump starter units have the batteries laying on thiers sides so be ware and take a close look at the terminals , if there's white powder around either one, I would decline that one or offer a lower amount and explian why.

I've only been able to recover 2 out of 23 we have here that had the battery laying like that. AT 7.50/ea WOW!! I would be tempeted to grab ALL of them just to have smoehting to trade in at Wally world.


Great 4 wheeler too:-)

What size tow bar you gonna put on the back:-) ?


Happy New Years!!

You can weld nice solar panel mounts out of old bed frames too.  So many uses for angle iron.  Looks like a nice project.  I almost had one of those old 24V electric mowers, but a friend of mine threw it in the garbage before I could get by and pick it up.  Rich

Perhaps put a plywood box on the back, open top with a tailgate. If its hinged on the bottom across the middle, you can dump out the cargo (hay bales, lawn clippings, etc). Looks like a lotta fun!

Yeah, but bed frames are harder than the hobbs of hell. I ruined three titanium bits trying to drill holes for solar panels in mine. Actually had to go buy a cobalt bit, nothing else would drill through it.

Keep the bit sharp and drill slowly with a fair bit of pressure, fast and you'll just burn up the tip.  I like to keep the speed so that you can see the metal peel off and curl up forming a strand or at least nice sized chips as I am drilling.  I keep a diamond file or stone handy for on the spot re-sharpening.  I resharpen my high speed steel, TiN coated, and cobalt steel blades.  I drill slightly oversized holes to give me a little play for adjustment when lining up the panels.  I also use old motor oil as a cutting fluid (free) when drilling them, although that can be a bit messy.  For cutting I use an abrasive cut off saw, which is no problem.  Rich

Thanks for all the comments and questions, The plan is to make a truck type bed on the back, but out of metal, I had also thought about a plastic cargo box, but bed frame and sheet metal comes cheap(free).


The batteries are all charged and tested before I get them, he sells the dead ones as scrap, as for a tow bar, here's the best part, I built this to fit on a utility trailer that we have, and its small enough to fit through local bike trails, its street legal here in Oklahoma, no tag title or insurance required.


Bed frames are harder than the hobbs of hell,  I ruined 2 sets of step bits, I did end up using a big slow 1/2" drill,and that was after replacing the first 2 sets of step bits, slow is the only way to go.


I hope to get back to work on it soon and will post updates as things progress,


Happy New Year,

 I've hit another snag on this project, the motor and transmission did not provide the speed I was aiming for, it had plenty of low end but was very slow, and had no range to speak of.


 I had gotten a couple of power chairs from the local scrap collector and decided to try the motor from one of them, so I cut out the old one and welded in the new motor mounts, assuming that the output shaft was 5/8"(I didn't measurer, just guessed), I headed to the mower shop to get a sprocket, who would have ever guessed that a 17mm shaft was so uncommon. Could not find one, I decided to make one, that went without further setbacks.


 I hooked everything up to a 24v 40A controller and went for a test drive, top end was perfect but was a little sluggish on take off. I decided I needed a bigger controller, and I knew that I had one off of another power chair that I had scraped out years ago.

It turned out to be a Curtis 1208-24xx, 55A peak 70A w/reverse and all kinds of neat little features, but I had not kept any of the controls for it, and had no idea what wire went where.


 After many hours of searching I found a manual online in .pdf format. So after reading the whole thing and making a parts list, I went to radioshaft, and got me a 10k-ohm potentiometer, and a couple of various resistors, came home and hooked up the controller to a set of battery's and a motor, IT WORKS!!!!


I was going to head to the shop and put it all together on the bike, when the doorbell rang, I pushed everything aside on the table, only to find out it was one of the kids in the neighborhood, who had already been told repeatedly, my little one was away at her grandma's for the weekend. When I got back to the table, I began to unhook everything when a loose hot wire hit the board somewhere, for just about 1/2 a second or less, I decided to test it again, its fried. It still goes forward/reverse and will stop, but it goes full throttle in both directions and when it stops the boards safety feature shorts the motor like a brake, there is also a resistor on the board that gets very hot very quick now.


 Could it be the potentiometer?? I tried to find a TV or radio repair shop to talk to me about how to test a certain parts of the board like resistors and diodes and such, but they don't exist here anymore. I'm reading all I can and learning, but have a long way to go. I'll snap more pictures of the bike, motor, and controller in the morning. If you have any thoughts on what it might be let me know.

G'day RandyOKC

I am also playing with a curtis 1208, trying to use it on a bicycle.

Unlike yourself my hours seaching on the net for the pdf you mentioned have not helped.

Would you be so kind as to email it to me?

This if my first attempt/experience with fieldlines so i am hoping this is possible

Cheers Permaclutter

I too am having trouble locating info on a older (1208-2222) curtis motor controller (I'm trying to repair a wheelchair for a disabled friend). any help would be appreciated. I'm also new to this board.

Thanks

I found a guy that swapped out the burnt up controller for $75, there is very little info on the net about them, I have the user manual if you need it.

A copy of the manual could be very helpful, could you e-mail a copy?
