Hello from Yorkshire ( England )
Hi there , hope everyone is feeling great this weekend ,just thought i’d intro myself
The names Lee , im a Pipe fitter / fabricator / welder based in wakefield love this kind of group collaboration … looking to build my first shredder … quick question what RPM does the gearbox need to be ?? .. and the great part all being funded with Crypto currency …
Hi Lee and welcome.
If you search the the subject of motor/ gearboxes for shredders in the forums there is a lot chat about the subject. But the short answer is it depends on the power of motor you have. The original spec is for a 2kw motor giving 70rpm from the gearbox. If you had a 1kw motor then 35 rpm output should roughly give a similar torque but will be slower at doing the job. It is surprising how much torque is required I aimed for a minimum of 150Nm but even that can jam up. Don’t underestimate the need to reverse the motor which can get you out of a jam.

Hi @astroguy. Just signed up, and looking around to see who might be nearby. I’m based in Huddersfield (pin still awaiting “approval” ;-). I found your post by searching for “Yorkshire” in the forums. I see you don’t have a pin yet either – so conceivably there could be many more people from West Yorkshire, here on the site, than the map currently shows.
All the best,
