Replacement Pulley for Tapered Shaft

[BDLS]

The seller of these has put a 55mm on amazon at my request.  This is the only other size avail.

While that pulley may help. I think this is my best upgrade yet. I have a 200 rpm minimum on my servo.  So this 6” pulley got me to 100rpm at the machine.  Should see 70 rpm with the new motor pulley.

Hello Friquant, I have found myself in the same situation. I didn’t know it would be hard to find a pulley after I purchased the motor. In my mind it seemed like it would be a common modification. 
 

I just set up my first 3d printer over the weekend and have no idea how to design my own print yet. Would you be willing to share the file for your pulley? 
 

Thanks

Matt

Here's an idea! Bolt a new pulley to the original one. We don't use our machines at commercial speeds and we're not talking precision engineering here. I wouldn't even bother changing the alignment. It might cause some wear on the inside of the belt but at the rate we use em I imagine it would take quite a while before having to replace.

Toxo, yeah that’s very true and def something for me to look into. Thank you!!
 

I was also just researching speed reducers which are really pricey. Honestly I can’t see why or how those things cost so much. They appear to simply be a pulley mounted to a cast bracket with a bearing.

There have been a few posts on here from members making their own reducers, it can be as simple as a shaft, two pulleys, two bearings and a frame to mount it on (can be wood or steel).

Yeah, but whenever I price the pieces out, I'm into $50 or $75. Somehow my pile of stuff never seems to have what I need.
