The Seig X2 mill and its derivatives must be the most modified machine sold going by articles on the Internet. Other than fitting DROs mine was standard and was mostly OK for my needs and size of workshop, however the 'head drop' caused by the poor spring design started to irritate and I have just fitted a gas strut.
What a difference!
I will not go into detail about the mod as it is well covered. Basically I copied the Little Machine Shop kit and used a strut from a Peugeot 106 bonnet.
