Rockford Posted January 19 Author Posted January 19 Turned my attention to the driver's side of the block. Built an injector pump, drive, lift pump and governor housing. Bent up a set of injector pipes from 0.5mm wire, they're a bit rough but they're passable. They're so bent around because injector lines for hydraulic injectors (which all except maybe Cummins and Detroit were), should be all the same length to avoid injection timing differences. The longer the pipe, the more deflection in the wall of the pipe when the pump builds pressure and thus you get a later and shorter lift of the injector needle. Just a boring fact wandering around my brain. For the injector pipes I stripped the insulation off the wire and glued six pieces together, then cut a slot in the top of the pump to hold the row of insulation. Once secured, in could use them as sockets to receive the actual wire and keep it spaced neatly. Also built a compressor from plastic shrapnel lying in the bench. Added a fan pulley to the front cover, that's just turned up from sprue in the chuck of my drill. That's the beauty of doing these things, everything is so small I can just use all my offcuts strewn across the bench as raw material. 4
BK9300 Posted January 19 Posted January 19 Never knew that about injector lines - sure makes sense. This engine is going to look great in primer/paint! 1
Rockford Posted January 24 Author Posted January 24 Confined to barracks today by this storm that's battered Scotland and Ireland, +100 mph winds they've suffered. We've just had 60mph so not so bad. Took the opportunity to add more to the Caterpillar, PAS pump in front of the compressor, PAS reservoir on the back of the head, starter motor, alternator, front pulley on the crank, fan belts from elastic cotton and a flywheel housing. Still need to do a fan and engine mounts. 5
Biggu Posted January 24 Posted January 24 Wow , Steve. Fantastic scratch building. That is going to look fabulous under a splash of good old Cat yellow 1
BK9300 Posted January 24 Posted January 24 Brilliant work, Steve! (hope the storm doesn't knock out your power) 1

Blue Monday Posted January 25 Posted January 25 Stunning work, Steve. Have you a count of all the scratch built parts you have crafted for your engine? BM. 1

Rockford Posted January 25 Author Posted January 25 Today was just a case of adding the engine mounts. My mind was on something else today. I want to do a transmission this time, the kit pieces is not even a starting point it's that bad. I took the Ford LTL9000 engine and transmission to use as a pattern, this is a fantastic little piece! I was looking at the rear casing detail thinking about how to model it and I just thought I'd jump into a new world. I balled up some Blu-tack, sprayed the rear transmission casing with olive oil and pressed it in. Then I mixed some epoxy resin and filled the mould. It turned out pretty good. It looked really rough at first but as I cleaned it up it really started to look good. I coloured it with a blue Sharpie so I could see it properly - I'm amazed! The caps on the countershafts are clear as are the fillets on the output flange. First try at casting and it's a real thing! Trimmed it down and it's great. I've just got to make a transmission housing now. 4
Rockford Posted January 26 Author Posted January 26 This truck aint going nowhere without no gearbox. After successfully casting the rear causing that houses the range change and the splitter, I needed to formulate a plan to build the main casing. Looking at the Ford unit I deduced that the main casing could be sliced into three main cross sections each with their own profile. I built the rearmost sort out of shrapnel on an end plate, then made a thin middle slice out of a piece of green offcut from a KW T600. The forward section was the trickiest, I copied the layout of the real thing and placed two pieces of tube where the countershafts would be because they form dictate the shape of the casing, then built the rest of the casing around them, adding the various bulges with dtrips of card where necessary. A good session with my files, finessing the contours and I don't think it looks bad at all for an afternoon's work and a first try. Need to leave it to set properly and then finish it off and add a bell housing. 4
cifenet Posted January 26 Posted January 26 Steve, your creativity on this is very impressive. I also like how you are adding each section using different materials to construct what you need. 1
Gary Chastain Posted January 27 Posted January 27 Steve, I just smile when I read your posts, you bring back the true essence of modeling. Well done sir. 1
Rockford Posted February 2 Author Posted February 2 Made a bell housing out of a inner wheel from the Revell Pontiac Firebird. Shaped it in the drill and added the top mounting lugs (not used on this truck), the inspection cover on the bottom and the clutch release fork shaft bosses. Engine and transmission mated together. I have started cleaning the chassis to accept the engine. 1
BK9300 Posted February 2 Posted February 2 Just a marvelous job, Steve - great to go through your updates! Lots of first hand knowledge being demonstrated here. 1 1
Rockford Posted February 3 Author Posted February 3 Cleaned up the chassis rails, removing all the remnants of the casting of the inset oil pan etc... Fabbed up a set of engine mounts from plastic card and did a fitting - plopped into place nicely. Had to just do a little bit of an adjustment to the cab floor to clear the turbo. Shortened the driveshaft front section up to the centre bearing. Looking good, just another 30-40 things to do to make it look right: inlet and exhaust pipework, shift lever island, linkage, brake chambers, steering linkage, etc etc etc... All because I wanted something to see through hole at the back of the doghouse!!!! 4
