It's a fine idea if you can find the right size and then make the cuts flat, parallel and square to the axis. On the other hand, if you could do that then it would suggest that you already own a lathe, which makes me wonder why you asked the question in the first place 🤔
Ah cool, thanks! I’m not sure how many I’ll need yet but when I do I’ll check your site and see how much it costs.
Was also considering getting a length of suitable Id / od pipe (prob be stainless steel) and cutting it to what I need.. is that a shit idea?
