Hi,

In the photo is the shinpad area of a pair of tree climbing spikes. The left one is broken and to repair this do I need to create a mould?

I have watched all the other tutorials and have a fair idea of the process but none covered a damaged edge.

It doesn't have to be pretty and it is not being subjected to huge loads (I believe the damage occured in transit).

It is not PPE so there can be no liability issues.

If I have fun I may make some bits for my motorbike.

Any advice will be greatly received

Owen

hello

This is what I would do.

Get a piece of aluminium sheet and bend it to follow the profile from the inside.

Put packing tape over the aluminium to act as a release film.

Bevel back from the broken edge at least one inch and use 80 grit paper to etch the surface.

Now clamp the aluminium plate snug from the inside and wet lay up your epoxy carbon over this.( the plate should extend farther than the missing part you want to make.)

It should be pretty uniform. Put peelply on this to help consolidate the carbon layers.

Once cured the aluminium will peel away cleanly.

Now scuff the inside, overlapping the area behind the bevel you did on the front

Now lay your carbon on the inside as you did the outside, peelply again.

Once cured you can trim down the excess and flat sand a bit.

If you want to go nuts cosmetically you can brush on o smooth layer of epoxy resin only.

Hope this helps

Fred,

Hi,

Here is a view of my finished repair for anyone who is interested. Not much time was spent making pretty as it is a tool, just a quick rub.

Thanks again Fred for your indespensable advice.

I have to confess to rather enjoying myself so will endevour to make some other bits

Owen

nice job !
