Update: right now all I have is a ball park figure of $1000 for three shredder units cut, machined, and welded. Olivier and Santiago are the only people to get back to me so far, but the more people get in on it the lower the price per unit will drop. Kevin, the machinist working on this, is redrawing the the plans to work with standard sized sheets of stainless steel. He is definitely a believer in the cause and wants to keep the costs as low as he can for us. Hopefully the other folks in Texas are interested in coming on board.
From what I’ve seen, anything that spins can be used to power the shredder. My shredder will be bicycle powered. If you wanted to use washing machine motor I think that would work great. All you will need to do is experiment with different pulley rations. A trip to the salvage yard should produce a verity of pulleys and a serpentine belt from the front of en engine. use the verity to find the most suitable reduction to drive the shedder slowly. A reduction can be achieved by having a small drive side pulley and a larger driven side pulley. the larger difference in size the greater the reduction.
I’m only familiar with simple shapes being extruded into long strands. If you were to pump hot plastic into a mold a few obstacles come to mind. The pressure to force the plastic into the ends of your mold might exceed what this design can achieve. You would probably want to have a hole in the opposite end from where you inject so the plastic could flow through the mold and not be crammed into a dead end. A restriction would need to be present so the input side would need to be larger than the output. I would start with symmetrical designs to ensure uniform filling.
This is just a very rough guess. I will let you know if or when I get this far.
Lucas and Oliver, I have a machinist who is cutting and machining my shedder here in Dallas. I’m considering having the shop produce as many sets of shredder parts as he can from one whole sheet of stainless so we can all bring the cost down for each shredder. Please email me if your interested [email protected]
An idea to keep your colors strait: melt solid colors into sheets then cut into strips. Lie the strips in your preferred pattern and heat until they stick. This only theory, but I don’t see why it shouldn’t at least improve the result a little.
Awesome to see I’m not the only one. I teach Automotive Technology/welding/fabrication. My students were all to exited to get started.
Dave, there are lots of videos on Youtube that teach both crochet and knitting.
Tamar, you are awesome! I never thought of this as a way to use up old bags. I have plans to make a bottle stringer that cuts plastic bottles into very long thin strips that can be braided into rope, woven into mats or baskets, etc.
This is a great idea! Considering the possibilities of weaving and basket making you could really expand upon this. I’m thinking rugs, mats, and wicker furniture.
Hello Zack, where are you at in Texas? here in Dallas we should have our sheer built by the end of the month depending on how long it takes the CNC shop to turn out the parts.
