Spike problems

[agg221]

Be very careful when considering having a set altered. Without going into detail of the changes in microstructure which happen through heating, some are reversible, others are not. This depends on the composition of the alloy and its thermal history.

 

Most steels (including stainless steels), except the extremely exotic ones, can safely be forged and, with appropriate heat treatment, returned to essentially their original properties of strength/hardness/toughness. Titanium alloys can be forged, but are more difficult as the higher strength ones are sensitive to a transition in structure, which happens if they get too hot and is very difficult to recover, so very good process control is required. Aluminium alloys are the most difficult - there are some grades which are impossible to recover the structure and will be severely compromised in mechanical properties if heated.

 

If you know exactly what grade of material they are made from and post it up here it should be possible to establish whether they can be altered, but otherwise unless they are steel I would very much exercise caution.

p.s. just read Geoff's post below - above comments also apply to welding (I have no idea how the things are constructed and whether this is relevant, but specifying joining procedures happens to be what I do for a living so I can comment on that too if it helps:001_smile:)

I've got haix pro protectors and they have a loop at the back that it goes through but still doesn't help. I wear type c it's the width of my feet which is the problem, I'm not sure which ones I've used used Afew, including the Velcro straps ones, which I think are a lot comfy but again it's the actually width of the spike I put boot in.

 

If you can locate a good engineer, they could shorten the foot plate width if thats the problem. Making sure they cut & shut at the outside of foot end.

So pack it out, a timber and gaffer tape job till you get it right then get something more permanent made

Yeah I think il try packing it out everything is like this to fit me cos I'm so petite thanks. Ano I was abit weary about getting them reheated to fit

Use two sets of boots, and simply Screw the spikes on to the boot on the bottom of the boot.
