CHEAP PLASTIC SHEET STOCK!
Want to know how to convert PVC (or any thermoplastic) pipe/tubing into flat sheet stock in about 10 minutes? Instructions are written down on the flat stock in the picture. Its VERY easy and provides a great source of cheap sheet stock. A 4" shc 40 PVC pipe yields a 13" x .25 thick sheet. Length is only limited to your heat source and pipe length.
Caution: PVC puts off toxic fumes if you burn it. Don’t place it close to oven burners. I would suggest using a yardsale oven or heat source that is not also used to cook food just to be safe.
In case you are on your phone and can’t read the words in the pic…
- Cut your PVC pipe to the length you want
- Use a table saw (or whatever) to cut a slit down the length of the pipe. Caution-The pipe will try to pinch the saw blade so its helpful to set the blade low and push it through quickly.
- Heat the PVC to around 250F in an oven. This takes 5-10 minutes depending on the oven.
- Wearing leather gloves, pull the PVC out and lay it on a flat board or other flat surface that doesn’t conduct heat very easily. Its important for both boards to be similar material so the part cools evenly both sides which will keep it flat.
- Cover the piece with another flat board and put some weights on top or clamp them together for about 5 minutes.
- Enjoy your flat stock!
You can use PVC cement to bond layers of sheets to make thicker stock. I haven’t tried layering myself so I’m not sure how well that process works. Post your pics here if you try this or the layering and enjoy the results!
