getting classy chappy .... Class Act Fab Buggy *2

Well, if you increase steering angle, no need to limit it.

What people often mistake is that if you increase the angle it won't feel like you're increasing your steering ratio. It just goes further.

2.8 turns for 8" or 3.3 turns for 9.375" will feel the exact same and draw the same amount on the pump.




As an FYI :
piston area on this ram is 6.08 - 2.46 = 3.62
piston area on a regular 2.5 PSC ram is 4.91 - 1.77 = 3.14
You're gaining 15% of power and a shit ton of shat strength.
 
I did some rough calculator maths with a bit of computer sketching to figure out what size ram to use on the new build. Trying to get 45deg of steering requires shorter steering arms for a given ram throw. So a 2.5x8 cyl needs shorter arms than a 2.5x10 cyl, and subsequently will have a harder time turning the knuckle when bound up even though both of those rams produce the same force.

I was wondering if a 2.5x10 would be close enough to a 3x9 in force to make it worthwhile to use. Turns out the 3x9 still makes a good chunk more torque around the ball joints than a 2.5x10 ram would. Like not even close.
 
more progress was tonight on chassis number 2.

took 2 hours to get all this done. crazy how fast it goes. there was on bar where the orange line is, that we had to grind a tiny bit off to get a better fit. other than that easy day.

more progress mas made last night.
these front frame rails took longer than they should of. we were fighting a 1/8 to 3/16 out of square high low issue. turns out one bend was about 1/8 of an inch different than the other.

we could get the angles to match going up at lets say 18 degrees. but then the front flat plate for the winch would be level on one side and not on the other. frustrating and head scratching. then we compared the two tubes side by side and bam one was slightly off. no biggie/ add a tiny more bend and done.

gonna work on it again tonight at least thats the plan and should be able to get it the rest the way done. as far as the chassis that is. then on to the real work.

i was not gonna boat side it and leave it open under there but now i may. it would also give me a spot to put the upper link mount to also. i dont know. we will see once we get to that and see how things are fitting.
 
Looking good! I'd do the boat side tubes or some kind of sider tube there. Any rock that hits the inner structure will stop you on the trail.

kinda my thoughts also. and gives us one more place to run something if we need to. . i think the biggest thing i look at is it feels like the cage just stops at a dead node. i feel like it needs to be tied back into the sub frame. just what it feels like. but maybe over thinking shit like always.:lmao:

Personally I'm a big fan of the boatside. Previous juggy was boatsided and current buggy is too. Makes gliding across rocks or pivoting on/around rocks so much easier. Plus allowed the upper links to be protected, as well as give additional room for routing hoses, electrical, etc.
 
on to another update. i put a deposit down with TTR axle and hopefully be able to pick up a 14 bolt rear steer axle over thanksgiving weekend. all it is now is a retubed with 3.5 DOM and Cs welded on with knuckles.
it will add quite a bit of time by going this route because that renewable resource ($$$) takes time to fill back up. but over all this is where i want to be..

TTRAxle&FAB : We're watching. Don't want anyone shitting in your sunroof :flipoff2:
 
Turn the A spreader bar out more to work as a visor. Great progress so far!
 
Rotate the bar that connects the A pullers left to right up so that bar is will act as a sun visor. Helps keep sun and rain off the dash and you better.

ok as easy as that sounds it would require redoing that bar. it is notched exactly for this position. bummer too

Personally, I'd rather have it all be in line and give up that extra bit of visor....that way you can mount gussets in the corners that double as tabs for a polycarbonate windshield if you ever want/need one. If that front windshield bar area is all in one plane, it's easy to make a piece of Lexan/Macralon, etc. fit.
 
I was going to say its all probably designed to have the windshield V tubes in the same plane as the A pillars. Pushing that upper cross tube further forward is going to change all of that. I'd keep it as is for now.

Definitely seems like you need some bracing in there. Doesn't mean you can't do link mounts, but like everyone said, it's a double whammy with bracing the a&b pillars plus making it slide along stuff easier.
