Are you bored enough - to watch me have my foot cut off?

My plan is to get the 3D foot scan and custom moulded insert done. I will try to get hold of the .STL file for the shoe insert so I can print my own but failing that I will take a mold of the original and just make a loan in silicon or cork for all my shoes.

I did this before out of cork and it was way more comfortable than the hard plastic one I was given at the time. I am sure the tech has moved on, and the prices upward, so it will be interesting to see what the new stuff is like. I will keep this thread updated with the options, the pictures & the prices where I can.

Sorry they are not chopping my foot off* but hopefully you lot will still find this thread of some use.

* I am really NOT sorry

Pfft! I was looking forward to photo's of improvised prosthetic feet that you'd fashioned out of carbon fibre, aircraft grade aluminium, bits of lolly sticks and some duct tape

Seriously, thats fantastic news!

LOL. Eating celery sticks and beetroot dip while I look at the pics.

Hmmm, carbon composite skeleton with clear silicon outer for the shoe inserts...might be a good excuse to buy another 3D printer as I sold the old one...silicon moulding isn't something I have done much of, that could be fun.

Yep, lots of positives feeling pretty happy

i quit smoking in preparation for the operation -= the anaesthetists don't like smokers - but now I am not being operated on, shall I start smoking again. Is that a good provocation to the STW crowd to have a thread of it's own 😉

I went to the Podieatrist and he did a 3D scan of my foot which he then sent to some place in Spain to have an orthotic (shoe insert) made up that exactly matches the shape of my foot to provide maximum support. He will then add a bit to the heel to raise that a little and a bit to the middle so I can rock my foot a little when I walk to mimic ankle movement.

That sounds great but I have to wait 3 weeks so I thought I would have a quick go at making my own.

Take a 3D scan of my foot? Well, I am sure a foot imprint in some dried flower Oasis foam is about the same.

The bottom of this was lovely and smooth but I forgot to take a photo before using it for the cast and it got damaged removing the cast.

Pour in the plaster of paris and leave overnight to fully harden.

Find some aluminium foil from the car build project to give a sealed, non-stick surface over the plaster

All neatly wrapped ready to layer carbon fibre and some stiffener and make the insole.

Slightly off topic, but an old fella i cycle with was a farmer and got his right arm pretty much torn off in an accident with machinery

the surgeon who reattached it was a member of his squash club. A year later the farmer beat the surgeon in the club’s squash final using his reattached arm. Surgeon had mixed feelings about it apparently..

When I discussed doing this with the podiatrist yesterday, he actively encouraged me to try and then bring him what I had made to see if it was suitable or if there were bits he could add/remove to make it perfect. We also discussed making a silicon mould of the original once it arrives and then trying different materials in the mould to make the ideal composite insert.

The carbon layup is currently curing in my bespoke custom autclave.

Slight change of plan when I realised the heating wasn't on. Now under a vacuum bag.

which obviously pierced as soon as I pulled full vacuum but the patch is sort of holding and it is better than nothing

So, no parrot then..?  Norwegian Blue or otherwise...

Hope you hadn't ordered one in advance of the critical meeting.

The home made mould, didyou get a roll with it?

Sorry, not sorry!

The oasis is not far off the stuff the podiatrists used when making my sons shoe inserts. The moulds are sealed & when opened the material is soft but then hardens in air after a while.

Oasis is great for mould making as it gets more solid and holds its shape better when crushed but also allows you to crush it a lot. Most stuff either lets you crush it a lot and starts to fall apart or gives you great detail and solidity but doesn't crush. It is normally a bit too stiff for body parts such as faces and hands but seemed to work for the foot.

The carbon is loosely cut to size but still on the mould while it hardens overnight indoors on the radiator. hopefully updates tomorrow.

I have to say, I started reading this thread expecting to see the use of a Dremmel under the influence of extreme alcohol, and then became more convinced that WCA would, in an almost reverse Bicentennial Man style, start his journey to become more machine than man.

Glad to see we have stayed on the path of just using a shed to make high grade medical parts from leftovers.
