I've recently become the proud owner of a set of M&K S-150s along with three ST-1 stands. I need to shorten the poles on them to fit under my screen. I was wondering if anyone's done that before? Is it just a case of finding a place that can cut and re-thread the metal pole? Any one have any advice on what type of business I need to search for? I've no idea about metal work, and who could help with such a thing. Or are there cheap tools I could use to do it myself? Thanks in advance all.
