So I ordered a 15mm wide 14T pulley a long time ago from a site that’s based in my country, but haven’t been able to use it since I need to drill my own hole and don’t have access to a drill press, or drill bits yet. Anyways, to the point, is this pulley basically the same one as DIYs? My build is going to use Otang In Heats, and gonna use some gates 15mm belts along with it.
They are similar but not the same cause diy comes with a hole for a grub screw and even a key way making it easy to mount. A pulley without a grub screw is difficult to mount. Also imo it’s not worth the effort to drill steel cause you need good drill bits. I know this from experience cause I had to drill hardened steel sprocket with cheap drill bits without a drill press… Its something I never what to so again For a small hole like that use like a jewelry dremel should work fine.
In my opinion, yes cause in the end it will be worth the few extra bux unless you have some specific reason for using the pulley. For example, in my case I wanted to use chain for my pulley but no one currently sells chain pulleys made to mounted on wheels so I had to drill my own.
I’ve used Rs pulleys before all you need to do is drill out the centre to what ever dimensions your more shaft is and then drill holes in the side for two grub screws them just use a tap set to thread it.
