PFB Kalmar Terminal Tractor

[pigeonfarmboy]

Got started on the body work today. Going on a scania chassis I had kicking around. Probably won't do the 5th wheel lift like the 1:1s have. Just want a nimble tractor for pulling trailers around.

Still need to shorten the wheelbase by a couple inches.

hey PFB, thats gonna be smooth!

[SWAGGER]

Nice work, pretty fast too. You did all that body work in one day?

[pigeonfarmboy]

Couple hours, styrene is easy for me.

[plow jockey]

Great job!!! Your moving right along at this rate you should be done by the weekend.

way to long on the chassis. These are alot more fun if u can pick up and trailer then drop where ever u want, without touching the dolly legs.

Scott I think you missed the part in the first post where he said he still had to shorten it.

Oh well are you special. Lol

[Izzy]

LOL ... I like the "front" on the front bumper - good thing you label or it might have been mounted backwards... LOL .. .

[Brian in PA]

Looks cool Nathan, but i think you should try out a fifth wheel that lifts like the real deal. i know you can do it.:D

[MoRockN]

That is soo neat. I cant wait to see more pix.

[pigeonfarmboy]

I just said I wasn't gonna do it at first. Think a screw drive should do the trick. Have to see where I'm at for room once it's shortened.

[Espeefan]

Cool. Another one of these little buggers being built on the forum! It's looking good, so far. Yeah, I know, you're going to shorten the frame, but I can't help but say it - It's a large car spotter! Sweet! :)

[pigeonfarmboy]

Got cracking again tonight after class. Need to fab the front bumper and a way to mount all the body work. I just use CA and kicker to "tack" everything in place so it's easy to break apart when I decide how it needs to be.

Cleco clamps should be in every scratch builder's arsenal!

3-speed wouldn't fit without cutting a good portion of the floor. Gotta figure something else out.

[Izzy]

looking good PFB - how about a heavy duty servo to drive the lift? They can be a little more compact. Or maybe one of those Firgelli's all in one package screw drive! The cab work is real top notch.

Looks good PFB, you're making quick work of this.

Not sure why I didn't consider a firgelli, good idea sir!

nice work.
It´s look´s like my Kalmar :-)

this would work great with a gearhead for power ,don't need highway speed on it

Nice work PFB. If I might make one suggestion. You had mentioned that you use CA and kicker so that you can break it apart if it's not right.

Well I can see the reasoning in that. I would strongly suggest that you use either Plastruct's Bondene (http://www.plastruct.com/Pages/OnlineProductDetail.lasso?-op=%27eq%27&CCode=BOND-2) or their Plastic Weld (http://www.plastruct.com/Pages/OnlineProductDetail.lasso?-op=%27eq%27&CCode=PPC-2)
when using styrene. I use both. I use the Bondene when I might need a little time to get it positioned correctly and the Plastic Weld when i want it quickly.

The problem with the CA is that it can break, thus why you say you use it. The Bondene and Plastic Weld do just that they weld the pieces together and if it is going to break it will most likely not do it where you bonded it.

As for tacking the pieces together for fitment, just use blue tape. The reason for this is because the plastic Weld and Bondene will not work if there is CA on the joints.

Also for extra rigidity on 90° butt joints where possible (where not seen) I use a piece of 1/4 x 1/4 x .020 angle.

Just my two cents, I am in no way criticizing your work it truly looks great.

[grumpygrady]

maybe one of these ?

and this one mite do for your fifth wheel

[pigeonfarmboy]

When everything is in place I'll just epoxy the joints. Gotta sand everything down for that too so it bites into the plastic.

[pigeonfarmboy]

RC4WD planetary trans will mount up easy. Hopefully save some room for the rear lift too. Will have to experiment with different motors to see if I can get the right speed/power setup.

[Espeefan]

That planetary looks like it's meant to fit right in there, doesn't it? Would you happen to know the gear ratio, Nate?

[pigeonfarmboy]

They are 16:1

[Espeefan]

Thanks Nate. With Tamiya axles then, you'd have a 42.56 : 1 final drive ratio. That's not to shabby, but not all that low either.

[Roadmasters]

just ordered one of those trannys for my build, please let us know how you like it

[Dreamweaver]

That's the gear box I am going to use. Got it already just need the motor.

Nate the gear box is designed to use a 540. I am planning (after talking to TC) to use a 55t in the Shak.

[SWAGGER]

That looks perfect! I don't really see the point of a 3 speed gearbox, I only want one speed, slow! (and of course reverse). The Tamiya gearbox, don't get me wrong, its cool, but takes up a lot of space and seems like a bit of a waste of a channel that could be better used on something else. That RC4WD unit looks like the perfect alternative, it's neat, fits the frame and runs a 540.
My ideal set up would be a CAT C12 with the motor hidden inside and feeding that RC4WD planetary gearbox.

[Dairyland Trucker]

I like the yard boss looks really close to the 1:1 unit quite cool...
