I don't. I actually threw them away about a year ago. They were essentially stock upper control arms that I had cut the end off where it mounts to the shock Tower and weld it some threaded tube to accept the rod ends. I did the same thing to the lower control arms also. The car had limited...

Thanks again for the replies. Here are some things to ponder... If I build the uppers with the turnbuckle gone and the tube extended longer and just have the rod end at the end of the tube, a high strength tube insert will be used for a 5/8-18 high strength 4130 rod end. The rod ends have a...

Thanks for the replies! The turnbuckle has male and female threads so both ends do have jam nuts. Rod Ends are generally rated for axial loads as a percentage of the radial rating. For example, a rod end with 20,000 lbs. radial load rating has a axial load rating of 3000 lbs (15% of radial...

So I made a drawing of the system and I outlined the section in red where I think would be the weak point and the point of failure. It's not going to bend at the rod end shaft since it will rotate...its going to bend at the red section i've outlined. The drawing shows the exposed threaded...

It certianly is...I am analyzing it statically first to see if 5/8 hardware passes muster, then consider dynamic loading. It is an upper control arm application with a spring perch for the coil spring so the load is variable and there is shock load to consider too. I don't have much hope in...

Yes that diagram was something I found on the internet. It does not depict the actual location of where the load is but it was something I just grabbed off the internet to illustrate what I was talking about. The parts that I included in the picture are all three quarter inch parts. What I'm...

Using the pic below, the load arm is 5.5 inches long and the effort arm is 9.375 inches long. The distance between the effort and the load is 3.875 inches long and this part of the beam is very rigid and i'm not concerned about the deflection or bending stress there. The load arm is where the...

Thanks for the bending stress info. Before I posted, I looked for a better word than composite whose meaning is "made up of various parts or elements" which fits, but "compound" would also work. Initially I went to the link below to calculate the system in a static condition. Its requires a...

Here is a pic of what makes up the beam. Threaded tube, turnbuckle and rod end with two jam nuts. The force is in the downward direction and the force is applied over the tube section on the left side of the pic. The threaded rod portions have the lowest moment of inertia. What i'm trying to...

I am analyzing a system that can be modeled as a 2nd class fulcrum. The link below about 1/3 of the way down the page shows an example of a 2nd class fulcrum. 2nd class fulcrum Link The part that makes up the beam is a composite part made up of a turnbuckle (see link below), threaded tube...

Sorry I dont have any pics, but i'll do my best to describe this. I have a 1" deep 3/4-16 threaded hole drilled down the center axis of a the end of a 1.25" square steel rod. A bolt goes thru the center of a high strength rod end (heim joint) and the bolt threads into the 3/4-16 hole the full...

I am building a non-regenerative repeater for several waveforms, one of which is AM voice. I'd like to reduce the IF filter bandwidth from 25 KHz to 10 KHz or less to reduce amplified noise power and ACI. I've seen filters as narrow as 6 KHz used for AM voice HAM radios. Since voice tends...

I need to electrically isolate the heat sink for a LM317. I don't want the heat sink to have the voltage on it (potential short hazard for my application). I believe that I can get a thermally conductive electrically isolating tape or pad for between the tab on the LM317 and the heat sink...

Thanks. It is a cost driver and because of the frequency scheme, it becomes a bit more complicated than just another LO. The SS signal is not a frequency hopping type. Its a direct sequence where a gold code is used to spread the signal. The BPSK signal is generated digitally onto a 70 MHz...

I am working with a supplier to have them build a repeater for a comm system. The repeater has to repeat AM signals (not SSB), a BPSK signal, and a BPSK signal that has been spread by a spreading code. The supplier asked me if they were to use the image out of a mixer that was the inverse...
