my first semi build (dump)

[chaseracer]

some of you would have see this thread on scale 4x4, or crawl canada, but thought I would repost it here.

I have always been interested in anything construction and heavy equipment, been around it my whole life and operating heavy equiment is also my career. as big as my passion is for it in the real world. I find most on my time on the internet is spend looking at crawl canada, or scale rc construction equipment. so I have decided to start my first scale construction build. it will be a Tandem Dump truck.

the base for my build will be a Tamiya King hauler.
here is goes
my first semi kit

cut the sleeper off of the cab, to make it a day cab and so the dump box will fit.



now it is on to making the box. I drew up a couple ideas picked one and started cutting styrene and wood to make the box. basic shape with no detail. sorry the pic a bit blury using phone to take pics.




if you noticed the staples they are to hold the two sheet of styrene to the wood spacer between the sheets
this makes my box side thicker and stronger but less weight then using many layers of styrene or metal. and will also alow me to add depth and detail to box sides.

now there are many box makes and type but I like the western style box, with horizontal ribs instead of vertical lines. so here I go cutting and shaping.

cut out sections for depth and add to give angle, shape and detail.





one side taking shape hopefully I can repeat for the other side

let see how is looks with the truck.



pretty happy with it so far with my limited skills.
really excited about building this one. my time is limited in the shop right now so this may take a while so be patient for updated.
thanks for looking

Jason. Looks real good. There's a lot of great work that's gone into the build. Keep it up and you'll be haulin dirt real soon. Lou said you were doing a screw drive for the box and there is a seperate thread here for it on RC T&C.

Looks great !!!! I have a question are those staples??? I have never worked with the sterlyn stuff alot now will those be pulled out then fill the holes or do you counter sink them and leave them in??and cover them with what kind of stuff??? like bondo or what ??? just curious looks good though guess i am just tryin to get a idea on the sterlin stuff or how ever you spell it lol

most of the staples will be pulled, they are holding everything together for now, now that the ribbed shape is done I plan to add a super thin skin of styerene to outside that will cover the couple staples that will stay , than I will do the rest to the shaping with filler. to give the seam a welded look. I hope

it is all trial and error for me I waste allot of styerne, good thing I get it cheap

Nice work, did you this fashion this off of the Oxford dump bed? Looks just like it.

Looks good man! Keep us posted.

not much new to post, bit frustrated. been working on lift system, based on a screw drive type setup, with a sliding block between two rails with a rod attached to it and the box. I tried pushing and pulling on the block. but the box will not lift, it just binds up, feels like it wants to rip the box off, unless I lift the box up a inch and it goes up no problem, can't figure out what the problem is?

[steamer]

If your mounting point on the slider block and the dump box are on the same plane or level you are right it would never lift. You'll have to pick a spot on the slider that is as low as you can mount the push rod. The same goes for the dump box mount. Try to get mount as close as posible to the floor of the box, maybe even build up the box frame. That way it won't try to push strait out, but will have some angle for leverage to start the lift.

Nice build keep it coming and us posted

I was wonder if you had a youtube account/ page and do a how to for us novice because I would like to build or modify a dump truck someday

[Espeefan]

That is a great looking dump box! Never considered using wood as a build material (even if just filler) for a box, but it's working really well for you and I can definitely see it being strong enough, light enough, and easy to work with. That's some good thinking.

thanks. well wood was what I had on hand to build with. so I said why not. if it doesn't work I will try something else.

been working a bit on the truck tonight, will have a update soon.

[Texasperry]

Caseracer. Nice work. I have a dump in my que so to speak.
But I wanted top say I agreee with you. I have always liked my models to look as if they were in the real world. That is why the racing did not stay in my blood. Same with helicopters. The scale stuff was too expensive when I crashed.

[chaseracer]

well guys no updates, I have been working crazy hours and then get family time only leaves time to sleep and look at the forum. but been busy with ideas so I can work when I do get time.

I want to make this truck look different then the standard KH, and make it my favorite make of truck Autocar, I want to make my cab look similar to a autocar A64b. like the one my Dad drove when I was just a little kid back in Nova Scotia.

I don't have any pictures of his old truck, but the are lot on the net. my only problem is round fender or square.

here is 2 1/24 scale model kits. not my own ( pulled from google)



I really like the round look but the square was used more of construction applcation, and is easier to do. I will also have to move the front axle back to get the autocar nose look

what to you guys think round or square?

[RCLogger]

I like the square look as it reminds me of the Kenworth LW... Nice project to keep you out of trouble for the winter.. lol

I say square fender, and it's awesome that you are thinking of building this into an Auto-car model. They are good old fashion work horses. Don't see many around these days. That model reminds me of the Auto-car dump truck, from the Die Hard movie, when Bruce Willis is driving it through the underground tunnel, flooding with water.

[steamer]

I'm a real fan of the old iron myself. The Autocar was a real workhorse and built as tough as they come. I remember riding lots of miles in one and they rode real rough. My favourite is the square fender one as it was the construction version and the round fenders were the supposed highway version. I think they were both used either way. Looking forward to more of the build. How's the screw drive coming along

i am more of a fan of squar my self but i like big lines.

[JAMMER]

You have done a real nice job so far keep it up. Ed

[Bigrigger]

I like the square kind better. For your first truck, you certainly are good with styrene! Keep it up!
