SAR   KENWORTH   TOW TRUCK
S. A. R = Short Australian Right hand drive
This is a tribute to Smudgie an old friend that pulled me home once & helped me out of a couple of other scrapes a long time ago.
Smudge was liked by everyone, he would always go that extra mile for you & there wasn’t a thing he didn’t know about block & tackle.
And big thanks to Swishy from  http://www.hcvc.com.au/forum/YaBB.pl    for his help with photos; even though I drove a SAR you forget the finer details’ after a while.
As you would have read on my C510 thread the money tree didn’t fruit this year & I’m having trouble seeing any small stuff (as I’m still waiting for the cataract opps & being only able to see out of one eye is so hard as you can’t focus like you can with 2 eyes, it takes all day for what I would normally do in a couple of hours BUT you can’t sit on the butt doing nothing, I can’t wait to get back to being normal again) & I need a break from the road train to refresh the mind; you will have also seen at the end of the T650 build that this was always going to be a future build, so I decided to have a go at building this SAR now, & the best part is 95% of this truck is leftover’s from the road train build.
DON’T YOU JUST LOVE FREEBIE’S
Kenworth brochure blown up for bonnet template & cab height.

To my way of thinking the SAR has a number of very distinctive features
 most obvious is the short pug-nosed bonnet & the height the cab is from the chassis a very radical for its day, being built to let the hot gasses escape from the engine/ gear box etc in extremely hot climate.

These models had a two piece guard with the scallop in the back half under the air cleaner so you could get the air cleaner internals out.

I contacted KW about this truck, and this was their response.
 “Brad wasn’t sure but thought it could have easily been as late as 78, something about the headlights being a tell tale for that vintage.”

& the non split guard.

Phil, is our resident historian…this was his response
“It was split when they had an air cleaner fitted to the cowl.  That’s what the dished out area was for so I assume that they split them when he air cleaner was fitted.”

This all sort of makes sense as I owned a “S2”Kenny with a 671 V6 GM & only one air cleaner & split guard.
 (http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/S2Kenny.jpg)

Then there was the over the top cab mounts, steering box under the cab behind the front excel & on most was the bent exhaust pipe as it went thought the rear cab mount.
This will give you a look at the American -V - Australian models

This truck was possibly the hardest to build of the 3 Kenny’s I have “kit Bashed” so far (T650, C510 now SAR Kenworth).
 How I wish that I was still making Fibreglass racing boats, Its so much easier to a make wooden plug, fibreglass mould then produce a product, I could have make them in ½ time it took to do these plastic bonnets replicas.
The King Hauler cab had the sleeper, bonnet, & mud guards all “cotton cut” (this is where you use cotton to cut the plastic) away from the cab with rear of cab filled in.
My SAR started its life as a “Globe Liner” chassis (because this SAR has a “B” train short chassis) with the bogie set back an extra hole on the bogie pivot bracket (to take the wheels to the end of the chassis) with the front springs cut & re-eyed to the first helper spring, spring mounts were rebuilt to bring the axle to a forward location.

CAB MOUNTS
RH Front, in the back you can see the steering box / pitman arm & steering column going it to the bottom of the floor.
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/kwsarsteerboxjpg4.jpg)
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/kwsarhood6.jpg)
The cab mounts are all out there in the open for all to see on this truck.
I found them to be fairly easy to build but still a pain in the butt!! to get them looking just right; all the mounts were bent / hammered around different plate thicknesses to get the right profile, then detailed to look like the real thing.
Not real happy with the look but it gives the elusion of what I’m trying to achieve.
Front mount RHF
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/towingdeck004-1.jpg)
LH Rear cab mounts
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/SARmountback1.jpg)
All most every SAR has a different set-up with the filter locations, hole in the back used if twin exhaust pipes are added, also a good storage place for the oil bottle.
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/SARmountback.jpg)
LHR
Both these mounts will also hold the rear of the g/box down (mounts hold down rear G/box lugs when bolted down)
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/SARrearmounts001.jpg)
RHR mount with oil filter
Oil filter is 3/4 x ½ copper pipe with gutter bolt heads soldered to the ends, 1/8 brass straps & wire bent to look like tubes soldered on, then drilled & taped to attach to RHR cab mount

Exhaust angle cut to go through mount,
(I used the RHS exhaust on the LHS to give me the angle back look.)
 (http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/TowTrucks-1.jpg)
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/towingdeck009.jpg)
Now the cab is in place, I will leave the rest of the bonnet / guards etc till it gets to hot to work in the shed (& don’t know how long these eyes will hang on for), as I can do my plastic work in the back room.
Now to start what I love doing the best THE METAL FABRICATION
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/TowTrucks001.jpg)
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/TowTrucks002.jpg)
The rear will be made out of all metal following Smudge’s truck as closely as I could from the couple of photos I have.
I will make the towing deck in the same style, with raised rear wheel wells, bevelled corners angles on the tow/pivot plate & a winch box with open/closed chain lockers.
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/SARbackdeck2.jpg)
Wheel opening are cut out of the side skirts & floor plate  with rear tow/pivot plate cut, bent & soldered onto the towing deck and then wheel wells were cut, & soldered in, every thing is then trimmed back to have a close resemblance the photo.
 Joe these fantastic spiders (wheels), helps to make the SAR look so much more like the real thing, a great product you have there.
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/backdeck.jpg)
now all this will be bolted & soldered on to a ½ inch “H” beam  then bolted  through the ”H” beam to the chassis of the truck, as well as being bolted to back of the truck through the towing back plate.

For the steel tow body fabrication I am using a similar technique that the old timer panel beaters used called “lead wipe” where lead was used to fill in joints & seems  (similar to solder, they now use bog filler).
I solder both sides of the join/seams then file/sand away the excess solder on the out side face, it will be finished off with a quick coat of spray on putty to cover any filing marks, a light sand & ready for painting, easy as & nice & strong this towing deck is quite heavy, but that’s OK as I will need all the traction I can get when towing with the long pole.
 Cut out & soldered in the tail light boxes, made the “D” shackles out of different size wire added a multiple height towing hinge.

(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/sar002.jpg)
CRANE TOWER
 Was made from brass” K&S hobby tube” with all of them having bolt inserts soldered & pined inside them, then notched out to take the hinge piece, the lift head plate was cut to the desired shape, the centre pole will have a slip & 3 pin centre for change of lift angle, along with the chain tubes, looking somewhat like the real truck.
The upright poles were angle cut a 1/2inch from the bottom with hand made pivot blocks that bolt though the floor plate; into the “H” beam
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/craindeck.jpg)
The roll over bar below was a little easer & stronger to build, & was added to the truck a few week before Smudgie was killed
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/IMG_22282048020x203602048020x20360.jpg)
Pulley blocks are cut from tin with a plastic pulley wheels, (I’ve added an extra block to help with the lifting load on the winch) the hook was bent from H/D wire and all bolted together with 1/8th tube spacers 2mm bolts. (cotton is used for the rope effect until a full fit out, box’s on the roll over bar are for tail lights)

Towing can be done with either a pivot axle lifting arm
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/SARtowrig001.jpg)
                                  or a ridged tow pole
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/ontow005.jpg)
CRANE UNIT
A 1/8th 3m crawler winch is bolted inside the box with some external body work, trying to get it to look somewhat like the real one.
Battery underfloor covered by the winch box 
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/cover.jpg)
Cut away between fins allowing air flow into the winch (winch motor is on this side)

I’ve been surprised at the number of modellers being so astonished with what I do with metal in my truck modelling, it’s as easy to work with as plastic, you just have to go about it slightly differently, this is how I join my parts together.
1). After cutting out & or bending , I run a ¼  inch wide grind line with the 4” angle grinder where I will solder on the flats & a ¼  “ under side of a  end join.
2). Then I put a liberal amount of “Backer Fluid” on the ground area  &“TIN” this grounded surface so I don’t have to put a much heat when soldering up later (as all I have to do is melt this solder on both pieces to join them together) as 2 bits of metal will suck up a lot more of the heat from the iron that one, (this way you will not loose already soldered joints, well not to many anyway), you can always put a damp cloth on the work already done to absorb the heat.
3) Solder them together with liberal amount of solder to both sides, then grind / sand off the excess & all that’s needed then is a small amount of filler for the scratch marks then primer & paint.
I use only normal core solder about 1/8th in diameter nothing special

Cab& roof
Glue in roof hatch, cut roof lights mountings & repositioned lights to the correct position, & fill in cut lines.

Bonnet / Guards
Now this is where the fun begins, get  cab the right height, bonnet the right length & right rack of angle to the cab with the mud guards & head lights in the right position / right height  on the guard etc etc etc.
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/TowTrucks.jpg)
Somewhat like it??? MMMMMMMMMMMMM Maybe,
the further away I stand the better it looks
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/sarcab001.jpg)
Trying to get that right look, the guards are completely wrong shape, profile & everything else about them, what a pain in the A#####, this is going to be.
I’m NOT A SCALE BUFF, by the wildest stretch of the imagination, but I still would like it to look something like the real thing.
(http://i225.photobucket.com/albums/dd284/TTTkenny/SAR%20Kenworth/SARgaurds002.jpg)
& because they are so popular here in OZ every body knows what a SAR looks like & has a comment / pinion  to make, (hope I can get mine looking right?)

Well guys you have caught up with this build of mine & I am off to the hospital on Monday 8th for my first cataract eye opp, with the next one in about a month’s time, so this looks like the last you will hear from me till next year, thanks for all the response & interest I’ve had from you all, & maybe we’ll see some more metal being used now

Tim,

I'm praying for you to have successful surgeries and that you will be seeing better than ever!

(You have to so we can see you finish the KW SAR!)
