Control rods. Riveted U.C.

Well done Lynn.....this will help loads of folk, myself included ! i am missing the short rods that go from the brake pedal to the steering linkage bundle at the bottom of the steering column.

the steel used is it anything special ? reason I ask is the longer rods must get some pretty load on them and some steel is more flexible than others.... i have always wondered about this.

I'm not that sophisticated, I arrived at medium tensile, because it aint mild and you have to be able to cut a thread into it. Are there any metalurgists on the forum that can do a rockwell test?

I only put in the time and effort because I thought it might help some bloke on the other side of the globe wot talks funny .
I will get to the short rods (they are the only ones left) Are you in a hurry?
I'd like to hear from someone with an original engine tie back rod. The thread on mine seems very long. Is it normal?

Lynn, Thats all very handy info mate. the engine tie rods do have a long length of thread because you have to be able to wind the nuts a long way on the bars. This is so you are able to jiggle them through the hull and then through the block, does that make sence to you ?

no hurry at all Lynn..... and as always your efforts here are greatly appreciated.

[Lynn Eades]

Richard, the short rods are there, but as stated need someone to check the details, as my sample, I made, and may not be accurate.
Thanks Shaun for the explanation. I havent got that far yet, so didnt know.

Sorry to resurrect the thread Lynn... The lengths quoted, is that minus the clevis pieces, ie it's the length of the actual rod rather than the assembly ?

Just getting ready to make up the front to rear brake rods, thinking about material, I cut the remains of one with ease using a blunt hacksaw today, my thoughts are if the brake works by being pulled on by the rod rather than pushed, then mild steel might be ok to use as it should be ok in tension.... Different gravy if they are pushed on though.

I made some using these dimensions and they were for the rod only, no clevis.

I ordered slightly higher grade steel. Mild steel today is generally crap. It wasn't much more money but seems to be better. For the life of me I can't find the invoice with the material name and number. If you ring a wholesaler and ask for some advise it would pay off. You'll be slightly limited in that you want 7/16 but the one I got has a little chromium in it as it's used it the petrochemical industry.
