Cable vs rod for shifter
« on: December 27, 2012, 05:59:39 AM »
Ok so I was in a hurry and put the shifter between driver and mid seat connected by a straight shaft.  Works ok, but little in way.  So was thinking about moving to dash or behind steering wheel (6 on the tree style)and using a cable.  Looks to be about 8-10'.  So any problems with that length.  It will have to curve out of dash and down drivers side, nothing drastic.

Length is not an issue. Too short radius bends will be. Make any bends as large a radius as possible.Bends add friction and slop to the action.

Whats too small a radius?  I was thinking 12-18" rad, too tight?

It'll work better if you use two cables (pull-pull) instead of one which would be (push-pull)......  twice as expensive though.

No need for 2 cables. 12-18" radius is good for 1/4" cable. A single 1/4 inch one will be fine. I admit the ultimate might be 2 smaller cables and/or if needing a very tight radius install.Can be a big PITA also. You will know if the radius is too tight when the inner cable will not easily slide in the sheath. This is for a shifter. That means the spring pressure of the shifter lever will need to be able to push/pull the cable all by itself easily. I have almost  zero slop in the single cable setup and a very solid feel to it. Just remember with cables that the straighter the run the better.

i was looking at a 1/4" and it claimed good to 5" radius.  It will need to make a 90* coming off dash to go down drivers side. 

Next question, good place to order one up?  And the throw on cable I'm guessing thats ea way or total.

Yes,it will do a tight radius but the internal friction will be too high. Fine for just a push/pull cable but for something that needs the shifter lever spring to self center.........................................well,not IMO.

Cable will make a good 12-18 rad bend.  Where/what brand for something decent good that wont break the bank?

You insinuate there is such a place. rofl rofl rofl ;D ;D I just go to ITP (Inland Truck Parts ,there will be something similar in most major cities) in Tulsa and have the guys make mine up. I prefer to have them build one end,go home,detrermine EXACT routing,mark it and taake it back for the other end assembly. I have found that even a 1/2" diff in length makes the diff between just right and fooked up.

Just curious but was the rod linkage not solid enough due to deflections? That could possibly be solved by adding more bearing points or going larger rod or even tubing.

This Morse cable is most likely too short for what you are trying to do, but I do have it available if interested. 56 1/2" center of mount threads end-to-end. Built by ITP.

Every time I have them build one for me they run around $120?
I let this on go for $50+ shipping to anyone that may be interested or needing this length BTW

Because of the seats I used, there is little to no space between them.  I had it jump out/change  gears a few times just from going over bumps.  The movement of cushions would push the shifter.  Finally adjusted it forward enough.  Its a little in way and middle passenger must get in/out from passenger side or risk being hurt or amused by shifter?  You can see in pic how close the seats are, and well it your not careful you cop a feel of someones leg. (see Enemy's face) LMAO

Sorry Enemy, that cable is too short.  :'( :'(

Can you use a bell crank to make your 90? You could then have all solid rod, one vertical and one horizontal.

What about placement as left hand shift? If I remember correctly you have about a foot of elbow room over there  ;D  Shortens the cable up and takes out a major bend? Or solid linkage to cable setup?
Just throwing shit out there..
