Ball end wrench?

Ed, what is so unique about the RPM arms that you need to look for special tools? I have regular OFNA made ball end allens that work great, but I never had to work on RPM arms, so I am missing the point of this I am sure.
 
I mis-stated the tool I'm looking for.
I'm looking for the tool that slips over an RPM rod end to help hold it while you thread it onto a rod.

One of these

That will work with these

Umm.. you could try rubber coating or even wraping a paper tower around some needle nose pliers. Worked for me when I needed to hold something without damaging it.
 
the little turnbuckle wrench included w/ HPI turnbuckles works....it just doesn't wrap around the end....it goes around the body of the ball end...hope that helps some...oh and if you need one and can't find anything else, shoot me a pm, I've got a few and i'll send you one (shipping for the little things maybe 1 stamp so its on me) :-)
 
What's the dimension across the flats. I might have a Lunsford wrench that would work.
 
Ed stop being a puss and toughen up.....lol...I've never seen a ball end tool.....but the pic above leads me to believe I can make one from a white piece of paper and a red X....
 
I know I'm being a puss but I'm a tool freak and like using the proper tool for the job at hand. At this point I'm using the Lundsford wrench on the TB and an ignition wrench on the ball end. The RPM ends are fairly soft and the wrench will slip when the resistance gets high. On my touring cars, the RPM ends thread on all the way with little of the TB showing and it gets tight close to the end.

I have a system worked out that gets the job done but was hoping to find an end ball wrench that fits the RPM.

Its 5.75mm or 7/32nds. If I could find a 7/32 open face wrench about 10-12mm wide it would due just fine. Seems as if all the smaller wrenches are not wide enough.
 
Here is a tool I found at www.hobbylinc.com

Thats the one I linked to and is the one I have now. The issue is that the RPM ends are larger and this unit wont fit. It works great for AE and Losi ends.
 
Sounds like ya just need a small crescent wrench. That's what I use. Costs about $2.99 at the corner hardware store, and fits all my rod ends.
 
best place for odd lil tools like that is harbor freight and cheap too....I bought a set of flat metal wrenches that have more than payed for themselves in all the weird stuff I've used em for......I wouldn't buy many hand tools from there but when you just want to try a cheap fix sometimes it's the best place to check...
 
I love HF. I go there all the time searching for cheap poop.
I have used a crescent wrench in the past but the ones I have (Good Ones) still have to much play in the jaws and slip off as the softer RPM plastic gives a little.
 
look in their $1 tool bins...I bought the whole set of wrenches...very flat and not alot of meat around the head...perfect for cheesy lil jobs like the one you got goin on......
 
What I do is take a hex head driver and stick it through the hole in the ball end. Then tighten from there, it gives leverage and doesn't break anything.
 
I just check all my lunsford's and the biggest is 5.15mm.
 
You could always file one out to fit 5.75mm.
 
I am assuming the tie rod and ball end are not attached to the car currently, or the fact that they are bolted in place would eliminate the need for the second wrench. So I have to ask, why not use man's best friend, the bench vise?

That is what I did to thread mine, and also what I use to build my shocks, or anything else for that matter when I could use an extra set of hands to hold something (soldering, etc). Hell, I have even used a bench vise to squeeze a pair of cutters through a hardened screw when I couldn't do it with my hands.
