Re: Hayes HD dump truck...RCP's style
Thanks! A small update. I have spent a while fiddling around to get things at the right height and fitting properly but haven't made many new parts yet. I did manage to add some small details though. Next will be mounting the cab to the chassis. The hood now rests on the rad and cowl as it should and will lift off for battery changes just like it does on my KW850.

Re: Hayes HD dump truck...RCP's style
looking good! that will be a stout looking truck. do you tac weld the cab parts together? how do you keep it from warping with such thin metal?

Wow. Very impressive. Great job on the metal work. Seems like a shame to paint it! Lol

Re: Hayes HD dump truck...RCP's style
I made a little progress with the driveline today. I didn't want to use a stock trans because it is so bulky and high geared. My attempted solution was to buy a cordless screwdriver and tear it apart. The one I bought came from Walmart and was only $10. It is a nice little planetary setup and seems to have enough power to spin all 8 tires on my bench with a few pounds of weight on them. I made up a little mount for the drive itself and bolted it into the frame. I used the 1/4" hex coupling, slotting it with a diamond wheel to allow fitment of the stock driveshaft. If it all works out I will have plenty of room for batteries and electronics under the hood...

Re: Hayes HD dump truck...RCP's style
Hi Reg that was a great idea. I saw it on You Tube and it looks like it fills the bill. Ed

Re: Hayes HD dump truck...RCP's style
Thanks Ed. Only time will tell if it holds up but I think it will work out fine. It is easy to swap out so for $10 I will buy another as a spare just in case. After joining the other island boys at the show in Campbell River I figured that a slow truck was way better than a fast one. Being set up on tables is just fine but a little bit of a concern when your truck doesn't like going really slow! My KH has an 85 turn motor with an 11t pinion and it is still way too fast to ever use 3rd gear. At shows we are always in a confined area so there isn't much need for a big, bulky 3 speed. This drive should have an output speed at the axles of around 120rpm at 7.2v. It looks to be just a little slower than my KH in first gear.

Re: Hayes HD dump truck...RCP's style
Wow Reg this truck is incredible! Do you use filler rod all the time on the thin stuff? Years ago I played around with TIG and could fuse weld thin stuff but could never seem to do well when adding filler rod.
Thanks for the drive idea with $10 Walmart screw driver, I've had one on my bench for 2 months in the package to power a screw drive. I finally took it out of the package to see how it did at building a set of frame rails last night. Surprisingly it worked well in its original form. Keep up the great work you always do! It's fun to watch! Kent |

I sue filler rod quite a bit but not always. It really depends on the joint but it always seems to be stronger when I use filler rod even if it gets ground off. Quote:

Re: Hayes HD dump truck...RCP's style
I think I see how you did the two piece wheel, quite ingenius.
The center needs to be welded in yet? Did the center start out as a piece of flat bar? The stock tires, do you have a vertical bandsaw? Cross cut the face of the tire using the hashmarks on the sidewalls for spacing... that improves their traction immensely.

I used my rotary table mounted horizontal to machine the grooves in the rims. I have never done this before as I have always used the lathe with a parting tool. Using the rotary table was WAY faster!...lesson learned! Yes the centers started out as 1/2 flat bar that I cut into rough circles. I then put them in the lathe and center drilled them to install a bolt. Once bolted together I held the bolt in the chuck and turned them to size. Press fit... Then back to the mill and rotary table to machine the oval holes using a ball mill. Once that was done I pressed and glued them together. Then it was back to the lathe to machine out the backside of the assembled wheel. After finishing that, I gave them a pretty aggressive bead blast to remove the burrs that were left behind after machining. Last but not least I flipped up the rotary table and drilled the bolt circle. Next process will be making the hubs for mounting the rims to the axles. Then onto the rears! Wow, what a process...no wonder that took a few hours! I will have to try the tire trick some day. I have ordered new ones for this project because I wanted the increase in height as well as a more off road looking tread. Reg Last edited by RCP57; 03-25-2014 at 10:14 AM. |

Re: Hayes HD dump truck...RCP's style
Well Reg for all that work, you can reap the rewards of some awesome looking wheels! They definently fit the bill for this build

Re: Hayes HD dump truck...RCP's style
Well thanks, I thought I would give it a shot and I think they turned out OK. Now I just have to make the rears, the hubs, and a spare...

Hi Reg Have you tried Micro Fasteners 2-56 nuts they have small pattern nuts HNBS0256 1/8 across the flats or standard 3/16 across the flats

Re: Hayes HD dump truck...RCP's style
Awesome work and details!
Basic question, how do you tap for the 2-56 screws? I tried to tap threads in aluminum but broke the tap. I was going by hand, and almost wonder if using the lathe would be better. |
