Hayes HD dump truck...RCP's style
 

Well, I figured when I bought my KH that I would get to this eventually:rolleyes:....
I have spent the winter months making stuff for other folks(thank you for the business!) but things have slowed a little now for RCP's and summer shows and commercial fishing are approaching. This is the first time in three years that I haven't had a least one scratch build going so to say the least I have been feeling the itch to build something for myself! I don't have any major plans for this build as I will be cheating and using a Tamiya chassis. I will however, (in my usual style) be making everything else from aluminum. My plan is to build a Hayes HD dump truck from the late 50's early 60's era....

Here's what I have done since this morning...

I started out just the same as I did with my beloved 850. I traced some things out and started cutting. Then some welding and grinding. 4 hours later I have a cab....

what , no paint yet ?????:eek::cop:

good job so far :)

Re: Hayes HD dump truck...RCP's style
 

I don't know how you do it just start and already you have 1/4 built, Like always I'll follow this post with envy at the speed of your builds Earl

Re: Hayes HD dump truck...RCP's style
 

As usual....
Reg, you are the Master :D:D:D

Awesome job so far!!!!!! :cool:

Re: Hayes HD dump truck...RCP's style
 

Great job on the aluminum cab!

Re: Hayes HD dump truck...RCP's style
 

Reg, why are you building such a small truck? You feeling okay? :D You're off to another great start! The cab looks very smooth. Almost hot rod looking, in it's raw state like that. Very cool.

Re: Hayes HD dump truck...RCP's style
 

Maybe by next week...lol

I'm really not that fast. It's just that when I'm "feelin it" I don't stop for breaks...Non union over here.:rolleyes:

Thanks John. I finally had some time to myself now that your box is at the powder coaters...:p;)

Thank you very much!

Nate I haven't been feeling well for over a month but I don't think it has much to do with the size of this truck unfortunately.lol Yeah it is small but it's kinda fun. I think this is about as close to a scratch build as I will ever do in 1/14 though. My inner child likes bigger toys best!:D

I got a bit more done this afternoon....

I guess when I get out of bed in the morning this build will be completed and painted.

We'll done. Keep up the good work

Reg Amazing metal work.. Better hurry up the sea is calling....

Re: Hayes HD dump truck...RCP's style
 

Awesome fab work. Truck looks great. At the rate your working it should be ready for paint by this weekend. Great job.

Re: Hayes HD dump truck...RCP's style
 

wow, looks good

Re: Hayes HD dump truck...RCP's style
 

Nice work! Looks good!! It looks so easy to weld like that,,,,, key word , looks, I've got to learn how to weld aluminum. Still trying to polish a tird for most of my welding!!

Re: Hayes HD dump truck...RCP's style
 

Yeah I think you're right Wayne, and if I don't get back to work the guy I'm building a box for at the moment will be calling too:cop:!lol

Thanks, Yes I am trying to get it done quickly as usual.

Thanks you!

Thanks...and it's not!...easy that is.LOL It's not that hard though for the most part. It takes a lot more co-ordination than MIG welding and that's where I suffer. I have a hard time keeping still enough and contaminate my tungsten...It makes me say bad words! Welding bigger pieces is easy but small stuff....:mad:

A little update from today. I made up a rad guard. some shutters, trimmed the fenders to there final shape, made the headlight mounts and guards, cut the hole in the front bumper, modified some old Clod rollbar lights that I've had in a drawer for 24 years to work as my headlights and then bolted it all together...

Re: Hayes HD dump truck...RCP's style
 

Reg your doing a heck of a job on the cab and fenders it looks real good. Keep up the good work. Ed

Re: Hayes HD dump truck...RCP's style
 

Awesome! Reg did Hayes use KW cabs? It likes an early kW cab. Keep it up!

Re: Hayes HD dump truck...RCP's style
 

Thanks guys. Hayes used their own cabs but I believe the design was basically unchanged from 1954-1975 when they stopped building trucks. They did have quite small windows like the early KW cabs that's for sure.

Re: Hayes HD dump truck...RCP's style
 

Thanks a lot!

This is a Hayes HD that we saw in Dawson City YT last summer. An old guy had been using the truck to haul paydirt but had since retired and the truck was up for sale. I believe he said it was a 1969. My truck is not really based off of this particular truck but they were all very similar as far as the cab is concerned.

Re: Hayes HD dump truck...RCP's style
 

Great work RCP! This i'm sure will be fantastic like everything else you build.

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?

Re: Hayes HD dump truck...RCP's style
 

Yes I tack the parts together in a few places along the seem first. You have to be very careful with the amount of heat you apply as you are welding though or it will still warp badly or melt a big hole in a hurry. This material is 0.050 thick, my other models bodies are all made from 0.063 which is easier to weld but harder to shape. Either way, fitment of the parts before welding makes a huge difference. The tighter the gaps are, the easier it is to weld.

Re: Hayes HD dump truck...RCP's style
 

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.:lol::lol:

Keep up the great work you always do! It's fun to watch!

Re: Hayes HD dump truck...RCP's style
 

That is a very common statement with Reg's metal work. We all thought it was a shame to paint the 850 also!. It just shows how great his metalwork is. We paint things to hide the raw state. This stuff has nothing to hide, leave it raw!:D

Mario

Re: Hayes HD dump truck...RCP's style
 

Haha, I bought two screwdrivers(one has two speeds) not knowing which one would go on to serve another purpose. I ended up using the $10 one because it had a little more rpm. Now I think I will keep the more expensive, 2 speed one for installing screws....until I need it for something else that is:D

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.

If it wasn't for gluing on detail stuff, I was contemplating polishing the cab... I really liked my 850 in it's raw state too but once it was painted it looked like the real deal to me...I even thought I could smell bark chips from the log sort once while looking at it(losing my mind, I know). The Hayes will get some paint. I just haven't decided which logging company colors and logo will be on it. Kind of a shame in a way though because I am proud of my skills with aluminum and most people assume that it is just plastic once painted...

Re: Hayes HD dump truck...RCP's style
 

I made some more realistic looking front wheels today in between other projects. They are 2 piece aluminum and bead blasted. Now I have to make the rears when time permits. I also ordered some more aggressive tires today:D.

Re: Hayes HD dump truck...RCP's style
 

I think I see how you did the two piece wheel, quite ingenius. :cool:

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. ;)

Re: Hayes HD dump truck...RCP's style
 

I started out with a piece of pipe for the rim. It was nice that the pipe was the right size for a change. For the 850 I had to use schedule 80 and turn it down. A much longer process...

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.

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:jaw:

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...

Re: Hayes HD dump truck...RCP's style
 

I got started on the front hubs this afternoon. I still have to make the dust caps and the spare. Then I can make the centers for the rear rims. I used 2-56 bolts as studs. I wish I had more scale sized nuts to hold the wheels on but these will do unless I find something else.

Sweeet! Looks really good:D

Re: Hayes HD dump truck...RCP's style
 

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! Thanks. I will check that out because I was planning to order from them again soon. It's funny how certain suppliers carry different things. I found a local place that has really good prices on the M3 screws I use ($4-5 per 100) but when I asked about stuff smaller than 4-40 with a hex head they didn't have a supplier for them. Micro Fasteners has been really nice to deal with and they have a good selection but their prices are a bit steep. The last order I made from them was around $70US for a bunch of metric stuff. I made the same order through Raider Hansen in Victoria and it was less than $30CAD. Live and learn to shop around but if someone has it but others don't and you need it, you have to buy it good deal or not!lol

Thanks again for the info!

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.
