[Chrisyc]

i have recently shredded several screws and after taking mr4tc apart so many times i new screws, does anyone happen to know the part number of the screw set for the mr4tc? it's not in the manual :o

[Doomanic]

What about in titanium?

[Chrisyc]

thanks, how much will these cost?
do they come seperately(bit of a silly question, i know! ;D) or do i have to buy 10 at a time, because i really need every screw for the car, which is 76 screws! :o

Add a "T" to the end of the part number, but not all are available.

They cost less than £2/pack.

Pack size varies depending on screw size.

[Chrisyc]

so if i needed 7 different types of screw size, it could cost nearly £14 :o

i hope not! :'(

is that for the titanium screws, or not

would it be worth getting the titanium screw? what advantages do they give?

[sosidge]

Weight saving, worth it if you have the money and the inclination, not a necessity by any means.

[Doomanic]

Ti screws coat around £4/pack and have less screws in them! :o

[Chrisyc]

ok, i dont think ill bother with the ti's

im with the regular ones.

but will the ti's have less chance of stripping?
...and they save weight??im already under the legal limit by about 200grams!!! i dont want to lose anymore(although i think everyone at my club is under the limit ;D)

[Chrisyc]

also i know this is a stupid question

but will cml stock these screws? ::)

[sosidge]

Ti screws are no stronger than steel, if anything they're slightly weaker.

CML most likely will stock the screws - but they won't supply you direct! - you need to find a shop with stock or someone who can order them.

PS Is it the screw heads you are shredding? If so, make sure you buy a quality screwdriver. Allen screws are less likely to shred, but you still need a good driver for them.

[Chrisyc]

huh...wats the point in ti's then(i mean, yeah you lose weight, but about half a milligram ;D)

yeah.i know ill have get to get a shop too order them in

yes, it's the screw heads that are shredding, i went out and bought a proper allen key set from B&Q on saturday, before i was using the one that came with the kit(i know..really stupid, i've been told ::))

[sosidge]

A B&Q allen key set still isn't what you need!

Quality allen drivers from your model shop is the answer - they're stronger, easier to use, more comfortable and let you tighten the screws better. My favourites are RPM, but there are lots of good ones out there, with the Yoke the only one you really need is a 2mm driver, but I also have drivers to fit the pinions and other smaller parts like CVD's.

[Chrisyc]

oh great..now im told
oh well, it's fine for me..comfort is not really what im after, just as long as they dont shred.

[Chrisyc]

i also cant afford them, they're about £15!, i already need tonnes of stuff for my car for next season as it is! for instance my spur has no teeth!!!

[sosidge]

OK, keep ramming a spike of cold steel into your palm and fingers...!

Honestly though, good tools are a great investment - once you have them you'll curse yourself for wasting so much time with the keys. They only cost about £7 each for the good ones.

You know that saying, "a bad workman blames his tools"? It's bunkum! If you don't have the right tool, you can't do a good job. That's why thousands of people are employed as specialist tool makers - a screwdriver and a bit of hammering won't fix everything!

[Chrisyc]

no..its got a plastic end! lol

i should know i had to saw off the part of the underside of the car which holds one side of the motor on!! >:( because of a shredded screw!!!!!!!! >:(
at the rate im going i'll need a new car soon!

[Chrislong]

Fastrax allen driver set is very reasonably priced, they do a metric and imperial versions so you'll have change out of £15.00 for them.

For the Yoke I like the RW Racing (I think) red 2mm allen driver, cos it is long enough to make it very easy to undo motor screws without removing skin on the chassis.

Always, with no exceptions use quality tools!

[Chrisyc]

yes..i know ;D

but what i was saying was that id just bought a new allen set that sort of fold out, and that was £8-9ish so i'm not really going to go out and buy another of exactly the same thing am i (well..practically the same thing, it migh not have a red end but who cares?! ney me ;D)

ordered the screws 2day(along with a spur gear..oh that reminds me, i had to saw off a whole bunch of nylon to get an aftermarket spur to fit..but lord it was worth it! ;D)
so soon ill be blasting it round the sdrcc track once more, victorious!(well when nobody else is on the track thats true! ;D)

[Oakley]

The other day I managed to round out a titanium screw...

Dont ask me how, but the screw seemed to tighten up in the car...

It was when I tweaked my chassis though and the screw was into aluminum (on the chassis brace) ... was on an SD

[Chrisyc]

yeah thats wat happened 2 me, about 5times!
including with my pinion!

[Chris Kerswell]

What you need is Torx :)

[Chrisyc]

wats torx ???

[Chris Kerswell]

Torx - aka Star Head :)

[Chrisyc]

well i've already got some hex screws on order ;D

[sosidge]

Apparently titanium can "cold-weld" into aluminium parts. A little grease on the screw when it goes in can help, or stick to steel for the aluminium parts.

[Chris Kerswell]

I think it is actually galvanic action if you research more into it. This is where the two metals help each other to oxidize ('rust').

[Chrislong]

Its because the two different metals form a battery. Best example is an old land rover, allmuminium body, steel bulkhead and chassis and the battery effect causes bulkhead and chassis to rust very quicky..
