Fabricating my own links,need some help!

RE:Fabricating my own links!

:shock: I have a question to ask of every member of this forum.I wrote a thread in the racing forum with the subject listed above.I've went to one of the hobby shops where I live at,to get this item.( INCLUDES: 6061-T6 Aluminum Tube SPECS: Diameter: ¼" Wall: .049" Length: 12" http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXS021 ). But however,the staff at this hobbu shop did informed me that this ittem in question was too thin to become suspension links.Now is this true? :shock:

I did go to Home Depot,and picked up one aluminum rod.The measurements of this item is 3/8"x36" long.Is this to thick to be a suspension link?If so,I could take it backBecause I could cut it down to 5-3/4" to make eight of them,and drill and tap them.But where could I find something to use to do such a thing as drill and tap,to use this item?I know that this item in question is a 4-40. http://www.crawfordperformanceengineeri ... hp?pID=153

Lastly I did find something at 1/4"x36" long,but it was to thin,and I could bend this meterial with ease.So at this time I could really could use some help with is one,and thanks.

Those are the tubes I am using, I've landed nose heavy a few times, plus many flat landings.

No problems at all,
Maybe the people at the hobby shop have never built a 4 Link before :roll:

Yea,to be honest with you Greg,I really think that they were tring to brush me off :lol:.Anyway,If I do use this material.What size drill bit should I use.And I don't want to forget about tapping it.Where could I get that tap from?So I could use this item? http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXD872

To be honest, at some point you just need to pull the trigger and build the darn thing.

The link material you've chosen will work in probably 90+% of situations. The advice that the LHS is giving you is because they are not making a sale, or rather, you're not buying what they're telling you, either way it's still a lack of sale.

Short story. When I bought my first clod I was clueless and trusted my LHS to give me the info I needed to make an informed decision and purchase the best I could for what I was asking for. Keep in mind that I basically know nothing OTHER than I want a clod. I was ok with the radio gear and servo upgrade. I was happy when they recommended an ESC. The only thing left was a battery charger. I told them that "money doesn't matter" and meant it, I wanted a good piece of equipment. What they sold me instead was a $50 piece of junk. It was ok for the first few charges, but after that it was nothing but problems. What pissed me off the most was that I specifically said that there is no dollar limit on good equipment, I want what is going to last and do the job. Ok, the story is getting a bit long now, so fast forward 6 months and I'm completely happy with all the purchases save one, the charger. After owning the truck I find several sites dedicated to the clod and I start learning more about the truck and the intricacies of an RC. I go to Tower hobbies with this new found knowledge and purchase another clod, ESC, Shocks, radio, and the charger that does what it's supposed to do ALL for the price I paid for a box of clod parts, radio, and a cheesy charger that's a piece of junk. On top of all this, I felt that the LHS was invaluable in the decision making process of my first clod and I wanted to support that. Unfortunately, unless my wallet was held open in front of their nose and I walked out with whatever garbage they were pedaling, they suddenly didn't have time for my questions anymore.

All of that to say, you've made some good choices, you've asked a lot of questions, now it's time to put what you've learned to good use and build your truck. Ultimately, we're all just guessing at what your needs are. Build your truck, find its weaknesses, and improve them to suit your needs. We're still here for you, that's not going to change, but until you put a few bolts under your belt and run the darned thing, you won't know what works for you and what doesn't, and all the advice in the world isn't going to make you any happier. The best advice at this point is to just build a stocker and run the ever loving piss out of it. Find the weak points and fix them. From there you'll understand what chassis length, link length, and the different materials are all about. I can tell you from my own two stocker trucks that you don't need any more than a good servo and an ESC to have MORE than a boat load of fun with a clod. Once you run one of these things you'll completely understand what you need to do to suit your purposes. 8)
I used to think I was indecisive, but now I'm not so sure.

here's how i made my links. first, i started with with 1/4" rod.

http://www3.towerhobbies.com/cgi-bin/wt ... XS016&P=SM

then i cut it to the desired lengths with a hacksaw and cleaned the ends up on the bench grinder. then, i drilled and tap the ends for 4-40 threads.

http://www3.towerhobbies.com/cgi-bin/wt ... XE214&P=SM

after they were tapped, i ran some long 4-40 screws in the links with a dab of threadlock. then, i cut the screw off, leaving about 1/2" of threads sticking out of the link to attach the heim ends.

i also saw in another thread that you asked a guy how long his links were. unless you have the same chassis as him, it doesn't matter how long they are. the lenghts of your links is gonna depend on your chassis and the wheelbase that you're trying to achieve.

In all honesty, if you're not sure how to drill and tap a link, don't. You can make links differently and still end up with the same result. Here's how:

1. Return the 3/8" solid rod to Home Depot as you won't need it.

2. While there, ask them for #6-32 all-thread. It should be in the same section as you got the solid rod from. You'll only need 1 piece of it as I think it comes in either 2 or 3 foot lengths.

3. Cut the tubes you got from Tower Hobbies to whatever length you want your links to be. Remember, the 5-3/4" length I gave you was for a wheelbase using OUR chassis. That length is also the overall length, NOT the tube length.

4. Once you've cut the tube to length, measure and cut pieces of the all-thread so they're 1" longer than your tubes.

5. Slide the all thread through the tube, and you'll have 1/2" of thread sticking out past each end of the tube.

6. Simply thread your rod ends on the all-thread. The ones you pictured from our website are threaded to accept the #6-32 all-thread without modification so they would be a direct fit. The #4-40 measurement for for the hardware that fits through the brass ball in the rod end.

7. Links done!

Good luck with your project.

I wanted to make my own links then decided against it. Didnt seem to be worth the trouble considering the cost of the ends.I have got 3 sets from Greg at and I'm real happy with them.They polish up real nice too.

I have a question for everyone.I am almost done with links.One of the links that I started is not centered.What could I use to seal up one of the holes,and start over again?I was thinking about using some hot glue or super glue liquid.

I don't think there is really any way to fill the hole and re-tap a new one...
if it's just slightly off center I would just run it as is or if you have more material make a new link... When I made my links for my crawler, a few of the holes ended up just slightly off and I haven't had any problems.
