Step 8: Making a Foot to hold the Shoe's Place and Shape

To hold the shoe in place we will use the left over soda bottle and some 1/2 inch PVC. What we will do is cut 3 pieces of PVC to act like the toes holding the shoe in place. You can also swap out shoes as they get worn out.

First take the leftovers from the 2 Liter bottle and cut a piece that is as wide and as tall as your shoe when the roof hits the 1 inch PVC. Next cut the three pieces of PVC the length of from the end of the 1 inch PVC to the end of the shoe. Since shoes curve, these three pieces will vary in size and will probably look like in picture 2. Take the pieces and glue them in the way that your shoe curves. For example, if your making a leg for your left side the smallest piece should be on the left and vice versa. Remember to look and compare the pieces to your shoe to make sure they are in the right order before gluing.

This is quite resourceful...clearly a winner. Not quite the best prosthetic on the market, but in a third world country, probably the best available.
 This is alright i suppose But The duct tape wouldnt support it for Long and The pvc would move in the shoe!
The duct tape just reinforces the JB Weld joint. The JB weld will hold together for quite a long time. The PVC won't move because I Epoxied it down in step 9 <br />
&nbsp;Oh yeah Sorry I must've gone past that a little . How about adding one of those Fake feet that you put in a shoe for it to keep its shape . That way you would be able to change shoes!
I just finished the device and is posting it, thanks<br />
<p>Can you send the picture, and show how you did it. My grandson has to make one for a school project.</p>
<p>you can send it to maples.margo@yahoo.com</p>
&nbsp;Ahh Cool I love the idea of pvc pipe as a foot . That makes the project Very cheap . I might have to build One It'd be handy To have three legs ! If i get it finished tonight or tomorrow ill Post pictures!
&nbsp;Update to myself (lol) . I have just bent the pvc Pipe Using a Hob and Because i didnt fill it with sand It has cracked ! I have to go to the shop tomorrow to buy some more pvc pipe and To get a 90 degree Fitting. I might try bending again as i have an idea To give the wearer His Heel Movement Back .
hey... if you like it a lot, can you please vote for it in the contest? <br /> <br /> Thanks a ton<br /> <br /> CT320<br />
oh my gosh...hilarious! as a below knee amputee myself I can laugh. ur idea rocks. let me tell u before I got insurance to afford a prosthetic I had many ideas being worked out myself. I think tho that to keep it on maybe try using one of those elastic knee braces over the whole of the knee up the thigh. much better support. good job. very creative.
I'm sorry but I'm an intern a prosthetics company and this would not work for a below knee amputee, Its not a simple task to walk on a prosthetic
That is an incredible idea. The only problem that I have discovered about Instructables is how jealous it can make people of other peoples' amazing instuctables. This, Sir/Madam is one of those amazing Instructables. I am in awe.
Um---sorta! Kinda the same basic idea of how my pros leg works---or doesn't. <br> <br> Can tell you that the socket ie the soda bottle is way too shallow to be used. And actual below the knee amputee like moi actually does NOT walk using their &quot;leg&quot; or &quot;stump&quot; we walk using a ridge built into and hidden by the socket that hooks UNDER the kneecap. <br> <br>Now if you could get something in there to FLEX the &quot;ankle&quot;----I imagine it would be awkward and stiff to try and walk on a completely UNbendy ankle. I can't do the twist the ankle manouver ---and in fact can't do the twist the knee part well either! which makes getting on a motorcycle um interesting. <br> <br>But the basic idea of a &quot;peg leg&quot;-- which is what your ible is-- for a third world app is interesting. <br>' <br>An actual amp ALSO uses a liner made of---well mine and others I have seen are some sort of silicone. So maybe the Oogru some one made here could be used. This acts as a shock absorber AND on mine holds a locking PIN which extends into a ratcheting receiver and HOLDS the leg to the liner. Others use a &quot;suspension sleeve&quot; which goes on the OUTSIDE of the leg socket and slides up over the leg and GRIPS it. <br> <br>This is less secure and actually my first leg got knocked OFF while held on this way on a steep and twisty bike ride. <br> <br>Other systems use air to inflate these liners and grab the leg. <br> <br>There is a design for a SODA BOTTLE PROSTHETIC ARM out there somewhere which uses the soda bottle cap to attach tools and utensils too and can be swapped out endlessly. And for free! <br> <br>And there is a guy on ebay selling hugely expensive &quot;plans&quot; on how to build a leg---the &quot;book&quot; runs you something like $200!!!!!! But an actual pros leg runs about $20,000 for a BASIC set up. And if you can get ahold of one---either find some one with an old one or get one off of ebay etc---you will see that for a below the knee model there is NOT that much tech involved. <br> <br>Mine cost that much and consists of a plastic inner molded socket which extends from the end of the limb to slightly above the knee---approx 11&quot; and I am 5'2&quot; tall. This has a carbon fiber outer shell. The pylon--the pipe part---is steel and titanium. The foot is steel---spring steel of some sort---and is covered by a foot &quot;looking&quot; shell. <br> <br>Some girls I know have used screws to hold on sandals etc. A wooden &quot;foot&quot; would work too with an ankle hinge. <br> <br>Taping to your leg? Not even. Would eat your skin instantly esp in third world conditions and let in nasty bugs. Tying it to your belt might work but it would be loose. <br> <br>Go look on ebay and see what pics people have of actual legs---and yes they DO sell them. Some go to South Africa where most people don't HAVE health insurance and there is a thriving &quot;gray market&quot; in used parts to make new ones or fix 'em up. <br> <br>Good basic idea tho!
Just wondering if you have anyway of testing this because I am almost positive that anything other than straight vertical forces would break the pvc &quot;shin&quot; off of the bottle neck. 150ish lbs is way more than a small amount of jbweld and some ducttape can hold.<br />
JB&nbsp;weld has been proven to be able to hold up to, like, 2000 pounds. I don't think it will be a problem <br />
