Title: Easy Radius Rods!
Post by: Tom Fox on March 13, 2007, 06:57:21 PM
All right for all of you who make these radius rods at home without a lathe...........I got a nice shortcut for making radius rods for your steering, brake & clutch linkages.

I use 3/8" rod ends on most of my linkages and tried the ol' drill and tap of a solid piece of aluminum and found it to be a frustrating trying to get a perfectly centered and straight hole drilled into it using a hand drill and a vice. Then you tap it and see crooked the tap is going in due to the wonderful hole you tried to drill straight!

Well...Here was my solution.....

I ordered a 8 foot long length of aluminum round tube from McMaster-Carr.

This tube has a O.D. of .563 and a I.D. of .327

Cut it to your desired length and tap it...No need to drill because the I.D. is perfect for a 3/8-24 tap!

The 8' length has a price of $10.58 +shipping (Dirt cheap......cost me less than $7.00 for shipping)

McMaster-Carr Part Number 1658T47

www.MCMASTER.com (http://www.MCMASTER.com)


I can make a total of 10 radius rods out of a 8' length of this tubing for my racer.

Being a 8' length....plenty left over to make spares to bring to the races!

UPS!!  Ordered yesterday morning...Had a 8' long shipping tube sitting in front of my garage when I got home at 5pm today!!  

I'm very impressed with that company...I have placed many orders and have had the best luck.

we use the same rod for our tie rods and linkage rods here at E.C. makes life easy for the do it yourselfer

Wow! great find. I seriously spent 2 hours drilling and tapping the radius rod for mine, and yes- did it with a hand drill. Almost impossible to get it centered that way. for $10... those tunes are worth every cent.

MOWMAN RACER, thanks for the link... Cheap shipping, where are these guys located. $6.00 dollars for shipping, I was wowed.

Thanks

Now this is happening,  :thumbsup: that is worth some karma points.
By the way I ended buying 2 8' chunks, for Team RPM's CP racers.

They have 5 or so distribution warehouses placed around the USA.

I don't understand how they can ship so cheap!

Wait till you see the shipping tube they send your sticks in!

I think the shipping container cost more than what they charge us for shipping!

What I have done in the past is weld a flange nut to the end of a piece of decently thick steel tube and then weld another nut on the end of that for some more thread.  The things have worked pretty well for me.

Hey Guys and Gals,

Another source might be metalsdepot.com.  I got som 3/4" tubing, 1/8" plate steel and some polished diamond plate aluminum at a very reasonable price.  Shipping was by FedEX ground and again reasonable.

They specialize in small quantity orders.

Title: Re: Easy Radius Rods!
Post by: jerb on February 19, 2008, 11:33:39 PM
you did use 3/8-24 taps? which is fine threaded, the 3/8-16 taps are a course thread, that could be your problem! other than that cant think of a reason it didnt work! let us know!
Title: Re: Easy Radius Rods!
Post by: mightymowe on February 20, 2008, 05:43:35 AM
Use some cutting oil it makes a lot of difference in how your threads turn out,especially when making threads in aluminum,there is cutting oil just for aluminum and different stuff for mild steel.
Title: Re: Easy Radius Rods!
Post by: markiemark on February 20, 2008, 06:39:11 AM
Ok Ill Check The Hardware Stores An Tractor Supply For The Oil. Yes I Ordered Fine Thread Taps An Tie Rods 3/8 X 24

Post by: markiemark on February 22, 2008, 01:21:23 PM
Ok Having Hard Time Finding Alum Cutting Oil. I Found Some For Steel But Thats All Is There Anything Else I Could Possibly Do
Title: Re: Easy Radius Rods!
Post by: Squidd on February 22, 2008, 02:59:20 PM
So where did you order tube from and what is actual ID...?

Mc Master aluminum is usualy .327 ID which should work fine with 3/8" NF tap

3/8" NF tap requires 21/64ths or .332 (letter Q) Bit...

Perhaps your tubing ID is too large/out of spec..??

 
Title: Re: Easy Radius Rods!
Post by: markiemark on February 22, 2008, 04:43:49 PM
I Got It From Them Using Part Number Off The Instructions. The Tap Is Tight In It An When I Srew The Tie Rod In It Prefect But As I Adjust It The Like Wear Out Of The Tube Intill They Just Pull Out
Title: Re: Easy Radius Rods!
Post by: mowdak1 on February 22, 2008, 06:12:34 PM
I know it's a ridiculous question, but... How deep did you drill and tap it?? Sounds almost as if you're bottoming out on your thread and pushing them out. Should be about as deep as your hiem joints without the lock nut on it, to allow for taper on the end of the tap.
Title: Re: Easy Radius Rods!
Post by: markiemark on February 22, 2008, 06:16:40 PM
i tap it the length of the tie-rod. With the tubing there is no reason to drill as the tap fits very nice in it already.
Title: Re: Easy Radius Rods!
Post by: birdman_express on February 22, 2008, 11:04:19 PM
If that bit that Squidd said to use is loose inside the tubing, you do not have enough meat inside that tube.
Title: Re: Easy Radius Rods!
Post by: markiemark on February 23, 2008, 09:45:10 AM
Im Going To  Get A Q Bit An Try An See. the tubings inside is supposly .327 so i didnt think it needed to be drilled but at this point ill try anything
Title: Re: Easy Radius Rods!
Post by: Tecken on February 23, 2008, 10:31:42 PM
Rapid Tap is a Multi Purpose tapping oil, good for all common metal types. It will be your very best bet. I agree with Squidd, your threads must not be quite deep enough or perhaps your tap is flawwed. A quick test is when you thread it in about half way there should not be much play in the threads. Back and Forth and Side to Side play should be minimal.

The best tapping fluid I have come across is Castrol's Moly Dee, slick stuff and stays with the tap.

Post by: nor66 on February 17, 2009, 08:09:38 PM
When you adjust your ends how much of the heim joint's threads are still in the tube?
Title: Re: Easy Radius Rods!
Post by: marcritter on August 12, 2009, 01:02:38 PM
Speedway catalog has them for ten bucks. There steel and swedged, from 3/4", 5/8" 1/2". From 9" 12" in 1" increments. 13 bucks for 13" to 20".  Aluminum ones in 7/16", 3/8", 3/16" for the same price or cheaper.

you can also go to any dirt car parts house. here in the houston area we have 4 parts houses, an they have all the rods and rod ends you can handle. a quick note the shifter rods we use on are dirt cars work real well for steerin,brake rods. they come with right and left hand theads already, an a cool note they come in different colors red,gold,blue,mill, an the hard to find purple lol

Post by: rceagle1a on February 07, 2010, 09:28:12 AM
I  bought two sticks of the aluminum tube from Mcmaster. I ordered it at 5:30 on Thursday evening and it was at my work place Friday at noon!!! Awesome service! Anyway I'm going the cheap lazy route and only using rh thread ends. I know I should have sprung and bought some ends from ebay that were LH and a tap but my team is in money saving mode now to try to build up some reserves in case of break downs during the season.I think regular thread cutting oil will be fine as long as you take your time tapping the threads and go a little and back it out some etc...

WD-40 makes a good taping liquid for aluminum    I use it when cutting aluminum all the time  Keeps the shavings from sticking to the cutters.
Title: Re: Easy Radius Rods!
Post by: bm82 on August 18, 2010, 04:55:33 PM
I've always used ATF (auto transmission fluid) for cutting oil on any type of metal. Always had good results too.

About twenty years ago I worked in a machine shop with a lot of old time machinists and they used kerosene on aluminum when using manual machines or by hand.   Been using it ever since.

to prevent aluminum from sticking to my cut off wheel i take a stick of candle wax to the cut off wheel, works really good

With that Mcmaster company how fair is their shipping? i entered all the parts i wanted and it would give me a shipping price. Maybe i computer dumb i dunno
Title: Re: Easy Radius Rods!
Post by: The Tank on December 04, 2011, 07:37:21 PM
Ive bought from them several times and shipping is as fair as anyone else. Its usually 10 to 15 bucks.

Thanks for the quick reply. I will give them a try.

does a .001 of the original size you used a really big difference because mcmaster only has now .328 not the .327
Title: Re: Easy Radius Rods!
Post by: Rooster on March 07, 2012, 06:04:09 PM
That is actually still quite a bit under the size the hole should be drilled for a 3/8-24 thread.
So you should be fine!
