The stiffness to weight ratio of steel, aluminium, magnesium and titanium is much the same.

Its CFRP (carbon fibre) that has a higher stiffness to weight ratio.

Take care not to use iso-propanol on titanium, it is possible that it will cause stress corrosion cracking even at room temperature.

Marchisio last OK, but the gear shifting is not as slick as Shimano or Sram.

Pigs are fairly good at getting rid of some weeds eg dock, they can dig the roots up and eat them, its not very neat or tidy but is effective.
Does anyone know if they are as effective with Jap Knotweed?

Nearly as good as Macaskill

Commercialy pure titanium, nowhere near as strong as titanium alloys such as 6/4, 3/2.5 etc.

The problem might be that it will not be a Helicoil but a taperfit bush / insert.
These are the common method of crank thread repair: Cyclus, Weldtite and Var.
It is possible that the bush will come out with the pedal.
But if it does stay on the old pedal, it just means that you get another bush or carefully take the old bush off the pedal and reuse.

SQ Lab grips are OK.
So are the Hutchinson Scorpion.

Var tyre levers can be handy.

There is a similar need for prescription specs as PPE (Personal Protective Equipment) at some workplaces. Something like the Bolle Tracker are worth looking at

Higher strength aluminium alloys do not always have higher FRACTURE TOUGHNESS.

"THE highest strength wrought aluminium alloys currently available are based on the aluminium-zinc-magnesium-copper system, and such alloys offer considerable potential for weight savings in airframe structures. However, these alloys have presented problems in service, arising from deficiencies in fracture toughness and fatigue crack propagation resistance together with a susceptibility to exfoliation corrosion and stress-corrosion, which have led to restrictions being placed on their use by individual aircraft companies and by procurement authorities in a number of countries. This situation has led to the wide-spread use in the UK and continental Europe of lower strength alloys of the aluminium-copper-magnesium-silicon type, even though significant weight penalties are incurred in the process. There has been a more general acceptance of the high strength aluminium-zinc-magnesium-copper alloys in the USA, where problems associated with their use have been partially alleviated by a willingness to replace components at short intervals, but even so during recent years a trend has developed there towards the use of lower strength versions of these alloys in attempts to improve airframe durability and reliability.

Make your own CFRP stuff:

Somewhere between £50 and £1000.

It is only in an auction that you find out what people would pay for it.

For example some ex-watertreatment works and other odd bits of land are sold through SVA.

Its easy to see which ones will or have got planning permission.

With some bikes / wheels it is possible to put the wheel in backtofront / the wrong way round, this gives you a chance to see if the gap between tyre and chainstay is the same (at the same time checking the dish of the wheel) for both the right and the wrong way.
If it is then the frame might be out of alignment.

"For many years the only recommended way to assemble a frame was by fillet brazing or brazing with lugs, and this was the way 531 frames were constructed. When Reynolds introduced 753, due to the nature of the material, these tubes needed to be low temperature silver soldered.

We now have a new generation of materials in 525, 725, 631, 853 and 953 steels. All of these can be brazed, but the most popular method of assembly is by TIG welding. (on 853 we do recommend that gear fittings etc are silver soldered onto the tubes).

There are many filler wires that can be used on 525/725/631/853 like ER-70S-6. "

The stiffness to weight ratio of titanium, aluminium and steel are much the same.
http://reynoldstechnology.biz/assets/pdf/rtl_steel_alloys_extract.pdf

The reason for the development of CFRP (carbon fibre reinforced plastic) is that it can offer a higher stiffness to weight ratio.
CFRP was originally developed by RAE Farnborough 40 years ago.

The problem of comparing different materials, even metal to plastics eg CFRP, is that tensile strength can be misleading.
Steel is similarly strong in commpression and tension.
CFRP is relatively poor in compression, but good in tension and very stiff.
A CFRP frame and a steel frame can be made the same weight and the CFRP frame can be stiffer.
A CFRP frame can be made as stiff as a steel frame and lighter, but the strength (resistace to compression and work of fracture) will not be so good.

There have been other attempts to make materials that have higher stiffness to weight ratios than steel etc such as Metal Matix Composites but they can create further problems.

Boron fibres had their own problems as well.

Just get it welded. ER70-S filler wire is OK.

Question one: how are they coping with MRSA?

Wool socks.

Morphine makes you constipated. You have to go easy on the stuff if you ever want to deficate again.

Tractor tyre sealant is cheaper.
