« Part 34: Mack grill, front bumper and safety cage Part 35 of Toy costruction series Part 36: Well I posted her »

Worked most of the day but this is all I got done.
I’ll bet I spent 4 hours trying to come up with a descent head light.
Let me tell you head lights are hard. lol
Played with the wheel wells and now half of my back safety cage will be cut off to fit. LOL- not funny-

I need info on a good distance for the fifth wheel from the cab???

The 5th wheel should be centered between the rear axles or just a little forward of center. Your cab to axle distance is dictated by the distance from the center of the king pin to the corners on the front of the trailer. That allows for clearance between the trailer and tractor when turning. On tandem axle tractors cab to axle distance is the distance from back of cab to centerline between the tandem axles.

Looking at your photos it looks like you will have plenty of distance.

The 5th wheel should only be used by learner drivers and positioned so as to stop them running up the curb and hitting parked cars…

Sorry Bruce, actually this post is what has made me realise what is referred to as the 5th wheel. I actually thought it was something like Dutchy’s small wheels on the dump truck. DOH! To think my father was going to call me Einstein….

Duckystein My dad was a union truck driver all his working life and I didn’t know or remember what it was either. LOL
Me and my dad were not close. Thank you very much LOL
Now all I need to know is what is a king pin. LOL
I’m guessing the king pin is the privet point of what. the trailer of course!!! Sorry.
I’ve read it 7 times and it’s starting to make sense. Thanks John for the info.
But next time please translate it to Dutch so Dutchy can explain it to me. Just kidding.

So the answer is I need to finish the back of my truck then find out how wide the trailer I haven’t invented yet is.
Take the distance of the width of the trailer cut it in half , which will give me the king pin distance for the trailer.
My double axial rear end will center the king pin.

So the answer is half the distance of the trailer width, from king pin to truck back, plus a little me thinks.
Simple ya right. LOL

Now that’s one of the reasons they make the 5th wheel on adjustable teeth thingys so it can be adjusted.

My heads starting to hurt. LOL

Joe I do appreciate the help just having some fun with it.

PS!!! Now I know why Toys & Joys makes the big bucks!!!

... in the room so how is she going to know…
You’re married, aren’t you? You know those impeccable creatures called wives have eyes in the back of their heads and are somehow linked into our webcams so they know exactly what we are doing…

Thanks for your kind words on the dresser. Yes it was a challenge as I wanted to make it visually the same as the original, warts and all. It was my first major Sketchup project and while I was a fumbling novice at the start I could just about class myself as an expert in not being a fumbling novice.

Oh yeh, I was very upset by your comments, but then the wife slapped me around because of my loud typing (or is it tiping?) so the offence faded into insignificance and furthermore, I have trouble reading your emails through blackened eyes.

Just kidding, you’d only offend me if you stole my loving wife (the one with the shotgun pointed at my head as I am telling you how nice she really is). I think my next model might be a hearse…. mine!

Sorry, I am taking the topic away from what I consider brilliant work. So I’ll shut up… for the second time.

Yes the king pin is the pin on the trailer that connects to the 5th wheel. The dimension you need is not the width of the trailer but the distance from the king pin to one of the front corners of the trailer. This will be more than 1/2 the width of the trailer.

If you use 1/2 the trailer width when you turn, the corner of the trailer will hit the back of the cab.
You can move that pin on the trailer forward or back some if you need to for clearance. Remember if a flatbed trailer you will need to place the landing gear where it won’t hit the back of the tractor in a turn and if the trailer is a drop deck you have to have clearance at the drop for the rear of the tractor there also.

I have seen some people mount 5th wheels in their short bed pickups and what it does to the pickup cab after their first sharp corner is not pretty.

I just got plans from T&J for the garbage truck. I will build that here shortly. I may then take those plans and modify them to mount another concrete pump on the truck. T&J doesn’t have an engine in the truck may have to modify the cab to accept an engine. It’s funny how plans just beg to be modified.

Thanks John for the extra info I would have figured it out sooner or later but thanks to your help I know it now not later when I would have to cut something out to make adjustments.

And thanks for not giving the short answer cause now I have a better under standing of how 5th wheels work and will never look at a semi the same way again.
I also checked it out a little on the net but your answer was much clearer and to the point than what I was finding there.

I had a quick glance at Dutchy’s comments and before I realised it was in Dutch, I thought he was commenting about my wife.
It’s bedtime now and I’ll let you boys get down to your serious stuff.

5th wheel???? I thought you were making a long flatbed truck to mount the drilling rig on?

Looking good either way.
