Hello everyone, I’m Sylvain, french mechanical engineer reconverted in my own local phone/computer repair shop.
It’s been years since I was looking for starting my own PP project and I finally start building the shredder.
My first goal was to do everything myself as I am not so bad with my hands^^ but after looking for laser cutting suppliers for a good 3/4 months, I decided to look for a ready to start shredder.
Thanks to Repair Café Pays de Meaux/AC, I managed to get one for a really good price.
As everyone on this forum, the quest for a cheap and powerful motor wasn’t a success. So I decided to try to do va Frankenstein version with a broken cement mixer I had laying around. The motor was ok, only the main bearing was down. This motor is 0,85kW at 2650rpm… Too quick and way too light for my shredder but it has a 1 to 8 ich pulley reduction and I had a motorbike chain and sprockets I’m my garage that can add an other 1 to 4 reduction ratio. After using my relationship to get a axle machined to fit my sprocket on, I just need to build a support for my shredder and connect everything together.
I made a pretty standard welded frame with bolted intermediate frames to allow some leveling. Added a old piece of countertop and it was done.
But as I was expecting, my moto is to weak to shred correctly, I can shred some plastic bottles without the lid and bottom and it’s better if I cut them in half…
I need to find something to put a better motor I think.
