Slow progress, but it's getting there.

Here's one of the "grinder bitch" doing nothing other than grinding!

DAMN you do great work. THat is absolutely FINE looking......

I can't wait to see that puppy on its feet :smokin:

--- thats one fine grinda bitch! lol:rasta:

Keep up the good work and keep the pictures coming.

What size heim joints are those, where did you get them, and how much?

What size tubing are you using?

Can you take a pic of the upper link frame mounts on the inside of the frame?

I did take pics of the upper mounts, but they came really dark. I will try and take some more. Upper heims are 3/4x5/8 and the lowers are 7/8x3/4. Lower tubing is 1 3/4 .250 wall DOM, and the uppers are 1 1/2 .250 wall DOM.

Heims and threaded adapters and tubing all came from Bob @ Roggy enterprises. Heims and adapters are from QA1. Tubing from where ever he gets it from.

Jeff

Here's a couple of the upper link upper mounts, but like I said, my digi camera sucks with no light.

What shocks are you planning on using for the new rear? Are you going to cut off the back of the frame rail, or do you think it is not necessary? How much are you going to move the axle back? You used F250 springs, the front or rears? Do you know what Lance's are? Damn good pics, starting to acquire the parts for mine. What kind of time frame are you looking at, number of hours to actually complete. Thanks man, and keep the pictures coming.

I remember you saying a while ago that you were PMing with Neckster about shackle angle on a 1/4 elip., just curious about what you learned?? What's the best shackle angle of a 1/4?? Straight up and down??

I'm not sure about shocks or even where I'll mount them yet. The rear half of the frame will be removed (I think it has to be done ). I moved the axle back about 3 or more inches (it was already 3 inches back as well)

Rear Heavy duty F-250 springs (thats also what Lance has).

From what I've learned, the angle makes no real difference other than axle position and ride height.

Jeff

Great progress, Jeff, and the results are looking fantastic. For comparison, here is a pic of my link frame mounts. I note that my upper links will be mounted a fair bit higher than yours, but I am not sure what affect the angle of the upper links has. How long are your links?

Also, you are correct about the shackle angle. According to SnortClown, that angle is only used to adjust the ride height.

Where are you going to chop the frame? Just behind the body mount after the spring hanger bracket?

How long are your links?

The angle of the links has to do with the Instant Center (IC) and the effective amount of Anti-Squat (AS). Take a side view of your upper and lower links and extend the lines where they will converge. That point is your IC. The link angles and lengths will also effect how your pinion rotates. Equal length will keep the pinion at the same angle, longer uppers will rotate the pinion up, shorter uppers will point the pinion down.

This is just some basic info that I have learned, but there is way too much info to give a complete understanding of how it all ties together.

Eric, you are correct as always. What I meant to say was that I am not sure of how much of an effect the relative difference in mounting position (and hence angle) of the upper links between Jeff's and mine will make. Poor wording on my part.

My lower links will mount just like your lower ones by spacing them out with some box. My lower links are gonna be like 6 inches longer than the uppers. Uppers are 36".

The angle is very important, the two links must intersect at the approx. the center weight of the rig (Bell housing or so) If you imagine an imaginary line after your two links end, try and picture them intersecting at the center weight point. With that said, if they do not intersect (I've been told by the experts) your rig will want to "stand up" whenever making a climb, because the rear end will just fall and continue to do so. This is where limiting straps will help a great deal.

Damn, I wish I had my body off for this project! Looks alot easier to work! Great looking so far Medusa!

Jeff

Thanks, and looking real good. Can't wait to see the write up to get all the details. Thanks again.

Jeff, gotta have the limiting straps. Remember what happened to mine at CALrocs when my rear folded unfer my truck. Basically what you want ot avoid... But looking good so far. I can't wait to getg started on mine on the bronco.

Dimitri

Jeff, gotta have the limiting straps.

Oh you know it's true! I will have straps for sure. I thought you were building a Cruiser?

Here's a pic of what my lower link mounts will look like. I just welded them a few minutes ago, so when they cool I will weld them to the frame (spot weld ofcourse!!)

Jeff

Ya know, there are some people who are good at re-enginering stuff........ and then there are those who show us how it's really done!
DAMN.... My hats off to this one!

Damn Jeff, That looks good and clean. If only I had some patience, I can build like you. I am just dying to get it all done at some point in the enxt few weeks. Nope to the cruiser, but the bronco is looking PHAT right about now. I gotta keep it semi streetable because it will be my daily driver, so just full width for now. whenI go 1/4 ellip on the back, I am gonna run a panhard and some radius arms with a wrisetd one on one side.

Dimitri

very nice Jeff!

I always thought that it would be better to have your IC as far forward and as low as possible. I realize this is almost impossible since we are lifting our frames so high for ground clearance. I think if you have the links converge (Instant Center) at the CG, you will have lifting forces split between the front and rear axle which may help minimize the Anti-Squat and walking of the rear axle while climbing. This seems like a good compromise for link length, link ground clearance, and link seperation. I have a few CAD drawings that I have created which I can move the IC point and centering it at the bellhousing seems like a happy medium.

With you lower links being longer, your pinoin will tend to rotate downward on droop, but like you said, the centered limiting strap will make sure the axle doesn't bind up the u-joint. Its not like you are building this rear suspension for catching air so you don't need the center to droop too much.
