UPDATE: Today the rig got some main air tanks. I wasn't really sure where these tanks ought to go, but the above mentioned website really cleared this issue up and my worries about the driveshaft being in the way, even with the crossover lines, were negated. Now I know how this works. The reserve tanks up by the battery boxes are 8mm aluminum tube, the main tanks are 10mm tube, makes out to about 10" diameter, it's OK. Here the pics; First off, a super thin, 0.1mm brass sheet strip was cut to the length of the 4 straps that were needed, plus some extra to compensate. This very long strip was wrapped around a piece of 10mm tube to get it coiled up a bit, then it was tack soldered so that the overall width could be adjusted for all 4 bands;
Here you can see the variations in width. I can't cut a straight line of sheet metal that's 10" long, the tip there in the inside of the coil will not be used. It was easy to make the rest of the coil one overall width;
Here the 1st coil was wrapped around the tube and the ends were tacked together, then the brace was bent and the two were soldered together;
Then this coil was soldered to a previously bent brace;
Here the finished deal;
The 1st one trial fitted;
Both sides done;
Next up is figuring where the air filter could be mounted, then more lines from the motor back to this area shown.
Thanks guys, your support and feedback is really valuable and is greatly appreciated. Dan, and Rob, going back and making something better is generally no big problem, I see it as just part of the process of getting something right, then moving on. There are a couple of these all metal builds finished on the shelf and parts like the torsion bars, although really kind of simple, stick out like a sore thumb if they're not done fairly correct. The deal with metal is, even the simplest part looks more real, add just a tad of "life" to it, and the parts or unit really pops out. It's worth the little extra effort to get it right. Thanks again. Finally I found some really super good pics of a custom WIP 359, especially hooking up the air tanks. Fantastic details, just I can't find the link anymore. Ugh! I think it can be done without too many problems though. The tanks are done, brackets are in the works so things are moving along. More later on.
UPDATE, Got it! Gator, take a look now. This is the way it should've been done in the 1st place. Sometimes I have a tendency to get lazy and just get something on there that slightly resembles something else, when the pics say "it sucks". This wasn't much more work than the first go round, so stupid, do it right the first time and move on! Here the new setup; First the parts;
The thin rod on top is to feed the unit through the frame rails, plus to let me hold it while soldering. All soldered up;
The center tube moves around to adjust to the angle of the torsion bar while feeding all of this stuff together;
Mounted, it works!
Now it's cooking;
Thanks Gator for letting me realize it can be done better!
Hi Tom, I like this thing! 25 cents, what a steal. I just had a laugh at a memory and experience I had at work before my military days. I sunk a D4 !! Working for a dredging company on night shift. The levee broke during a muddy and thin sand bed dredging phase, and something had to be done quick! Well, it was pitch black with only the moon shining, what looked to be firm enough was not, and the vibration of the D4 made it axle deep in nothing flat, soon it was above the hubs. Wet sand is like cement, not even a dozer gets out. I'll bet they're still talking about that maneuver! Cheers to a good time.
Hi Gator, Oh yeah, I'm aware of the function. Problem is, or was, there was too much function back there. Things were wiggly and it was getting unbearable to mock up, so I had to start attaching things permanently so as to get a decent and solid platform to work further with. This is what I meant earlier about "cheating", the lower torsion bar is soldered firmly, but the bolt lets it appear to be movable. What I can do though, is change the upper support. This is not much trouble at all, and actually I think it's a good idea to do so. Here's a look without the fat 3mm aluminum bar (it just slips over the thinner one);
Hey, I think it looks better without the fatter sleeve! I can change the upper mount easily. I'll make a U shaped bracket, just square, not rounded, then add a small tube to the end of the existing bar to make a "T". Then fit the "T" into the new U bracket and then run a bolt through the deal. Then it looks better. You're right. The fat sleeve just looks unfinished. I was lazy, but since the unit is sitting pretty, and fairly immovable, I can go and make a cosmetic change, no problem. I decided anyway to make a better block for the air lines, the 1st attempt was just too primitive, it's already been removed. I appreciate your input Gator! More soon, hopefully with the improved optic.
Mini update; The axles are secure. There's a little lateral play left in the brackets, they're double walled so they can move a little from side to side. The axles have to be slipped in from the rear then slightly pushed against the bracket opposite the torsion bar, this way the bar can slip into the hole on the tab that's soldered to the frame. Good thing is, finally the axles sit square and level, without wheels, and without me cussing and wanting to throw the frame out the window. Peace.
Whew! OK, this doesn't look like much of an update. But this is a big step forward. No tires in the way, and the axles sit nicely relatively firm in their respective positions. Now I can get at the air bags, mount them to the tabs on the axles from the bottom, mount the shocks to the same tabs, and this unit can sit assembled by itself in a quiet corner till final assembly comes around, further down the road. I'm happy.
Gino and Rick, thanks for dropping by and looking. Next up are the torsion bars. UPDATE: The torsion bars are finished. They're just different than the 1:1 units. Right now I've had it, the whole business back there is just wiggly as heck and I've been on my knees looking for more parts on the floor than I care to, right after this post I'm going to solder and glue what needs it to hopefully settle things down back there. The mounting brackets for the axles move up and down and sideways, also individually. The wheels aren't attached to the drums yet, the torsion bars can't really be firmly attached until the final mounting time, this after paint. The axles move around in the brackets too. Magnify this times four, and you get the picture. Soldering iron and CA are ready to go! Here a few final pics of the torsion bars. They kind of look like a dough roller, but already they work, no more movement sideways, even though they aren't firmly attached to the frame. Actually, this is just like the real thing, no more sideways movement with these things in place. Kind of amazing really, it's just a model, but still things kind of function in a similar way. 1st fitting;
From the front, the rear bar has to be shortened about a millimeter, the axle needs to go more to the passenger side;
There's a tiny chrome bolt holding the bar in position. The stub of brass peeking out the back will get a shot of solder. The axles are quite heavy and little tiny bolts won't hold all of this weight. This is cheating a little, but that's not important;
More of the aluminum dough rollers;
The other end of the bars fit into these tabs, soldered onto the frame;
OK. This is really a relief being finished with this ordeal, it's been bugging me for weeks, I just didn't know where to start. or how to even do the air lines/brakes. Step by step.
UPDATE: Here's Round 2 of the axles. this time around things went easier and quicker. Also. the sir blocks in the frame came out looking a little better, not as messy as the 1st one. Maybe I'll even do the 1st one over, I'll sleep on it. Here's a look;
The new blocks in the frame;
I had to relieve the bottom of the frame rails to give some room to hook these lines up later on, things are tight back there with those big axles.
The time is right to start the torsion bars now. Since I looked at the red custom truck up above, maybe the torsion bars might look good highly polished? Yeah, real sick, sounds good!
