Re: Unimat 3 - Belt cover removal
Hello: Don't think so. It is (apparently) the only way to get the cover off. At the factory they would not be doing something like that, complicated and rather manual intensive. I think that the job

Bonus! It contains a method of threading on the Unimat without buying the (rather expensive) threading attachment and guides! Will work for any thread, too! Just not for every object. Darn! But better
