Re: W000T
 

Good to see someone else who thinks that cutting a screw thread on a comm lathe is a little bit adventurous Rowie.:weird:
I don't think he realizes the physics behind what he is saying.
I just couldn't be bothered trying to explain it.

Steevo:tire: :lol:

lol, So true.....

hey i was just thinking of what you might already have, instead of having to spend so much money, if you really needed that screw.

Its good to see that many of you cutting me down are also helping with ideas to obtain obsure parts. I am merely trying to help someone who may not be able to buy what he needs in from a shop. Not every thing comes prefabricated, and half the fun comes from making it yourself.

I know a com lathe would be weak as shiat, but you could rig up some way to attach a drill to it to get the speed you need.

Hey sorry,
I don't think anyone is trying to deliberately cut you down. The fact is that trying to do what you suggested doing with a comm lathe would be an exercise in futility.

Being someone who has fabricated many parts for RC Cars, one thing that I have found is that there is usually someone somewhere in this world who can supply exactly what you need, especially when it comes to something as fundamental as a screw. If it was not a custom made screw to start with someone will have it guaranteed. You just have to use some detective work to track it down. That might mean a dozen phone calls or an hour scouring the net but persistance will always be rewarded.

Also to have a fitter and turner make some screws for you would cost more than you would realistically want to pay.

In the end no one is trying to cut you down personally we are just trying to advise against a improbable solution to his problem. Please don't take our comments as a personal attack, I did not mean it to be:smile:

sorry Samma3l,

nothing was actually directed at you, as a mechanical engineer and a fitter for many years i just know the danger that could result is some got it a bit wrong in the effort of trying..

I know in melbourne we have some great hobby centers that would almost have every screw that you could possibly need and on race days there is usually someone that would have what you might have lost or broken.. In worst case there is always a quick call to "the metric men" or "The bolt Bloke" who would definatly have whats needed..

anyway Samma3l, i hope no offence was taken in what was said..

Re: Screw This!!!
 

Darkman,
Another option also is Coventry Fasteners. I buy my screws from Queensland fasteners which is their Branch in Brisbane. They have both Metric and Imperial socket head screws in buttonhead, Standard and countersunk. They have them in both Blued Steel and Stainless Steel. The brand to ask for is the Brighton brand.
If you only want one or two let me know what size and type you want and I will send you a couple for free if I have them..

Steevo:tire:

Yes that's the place that's just down the road from my work but could not think of the name. Thanks for that. Mr Besercoe that's the place I was talking about Lee Brothers. very good place.


Coxy

psssst coxy... i said that.. lol
:lol:

Re: Re: Screw This!!!
 

Thanks for the offer Steevo, but its k, there is a coventry branch in Alexandria so I will check them out this weekend. What is Blued Steel? :confused: and is Stainless Steel heavier than the normal screws that come with a kit? :confused:

Its cool,

I never took it too personally, I was just offering up some ideas as to how you could go around making stuff. A com lathe seems to be the perfect size for making small parts like that, even if it is too weak to do anything with was my point. The fitters I had seen had big threading machines which looked to be too much. I had suggested making it yourself because I have a mate who can cast anything you want just about, out of almost any metal you want (chrome, gold, alloy),with only a little cleaning up of the object required. I go to him when I cant find a part I need (usually from a pair).

Re: Re: W000T
 

Hahaha... yeah, comm lathe would be last thing I'd think of.
Even after the "hobby/bench mini lathe".

If you want to a cut a screw thread, just thread the blank into a thread die.
That's what that tool does. Simple, easy, effective.



Steevo, check this thread out... :nod:
RED vs BLACK wires on Servo Leads?

there are some that are taught

and then there are some that teach themselves the hard way. I consulted every radio manual I had and none said anything about colours of wires etc. I now know the what is the right thing to do. Make fun of me if I make that mistake again - For then I have learnt nothing. This whole thing is a learning curve. The best way I learn is trial and error. Some smart guy once said:

The man who does not make any mistakes has not learned anything.

I can assure you that I will come up with many, many more errors for your amusment/frustration, but unless I make the mistake again its not really fair to make fun of my attempts at finding other ways of getting things done.

If you locked your keys in your house, you could call a locksmith. I would try getting back in through a window and if that failed, the roof, just to see if it works that way.

Re: Re: Re: Screw This!!!
 

A "Blued" Finish is a chemical finish that is given to the steel to make the steel screw look good. A Gun Barrel is "Blued" for example.
Stainless Steel is slightly heavier than a Standard Mild or Hardened Steel if I am not mistaken (correct me if I'm wrong). Stainless steel is also stronger and resistant to rust and corrosion.

Steevo:tire:

Re: Re: Re: Re: Screw This!!!
 

Stainless is usually denser than mild steels = heavier for same volume. Imho Stainless is stronger than mild steel, but usually Hardened or High Tensile fasteners are stronger than stainless.

Stainless is usually lot more expensive too, so I wouldn't bother using it in your RC car unless you have no other choice. SS hardware is common only on locations where corrosion is rampant, like on an sailboat or ocean vessel.


I buy my cap screws from Coventry too (previously known as The Bolt Bloke), I usually ask for High Tensiles. Depending on which store you go to, each has varying stocks of the smaller screws that we need. M3s are reasonably common but only some carry M2s in any shape or form.

Samma please.

Really applaud your lateral thinking, matey... but imho it is very misleading (and possibly approaching dangerous) to offer "advice" based on an unconsidered 'unique' viewpoint.

Nobody taught me everything I know; I too learn best by doing, but I don't do anything until I at least think a little about how to do it. Trial-and-error still requires a conscious thought-process behind it...

btw Have you ever used any lathe before?
(Can you tell the difference between a woodworking lathe, a metalworking lathe, watchmaker's lathe and a motor lathe??)

Unless one has a passing familiarity with a certain tool/gadget, its pretty naive to be casting aspirations as to what else it wasn't designed to do.



And yes, I'm the one who's seen (too late!) an idiot workmate borrow my favourite screwdriver to be used as a prybar... and some other idiot colleague try use my new cordless drill as a hammer.

Hope you'll understand if nobody offers to lend you their new $700 motor lathe... :(

(yes, it'll be handy to break in through that window but)
