I sent you an invite to join the Felder group. I purchased my Felder machines in 2001 and paid for the commissioning and it was worth it. I'm a retired machinist and since then I have aligned my own machines and quite a few other Fogger's machines and while it can be done, it's not a trivial undertaking, especially on the longer sliders.... it's like trying to force a wet piece of spahgetti noodle into a straight line.
While the factory commissioning may not get the machine as "perfect" as you would like, it will teach you enough to have an inkling of what is required in case you should ever want to take on the project, or fine tune the machine even better.
I have seen quite a few purchasers all bent out of shape about how their machine isn't perfect upon delivery, after all, they paid all this money for it, it should be spot on. They fail to realize that the machine may very well have been perfect at the factory, but it is then crated and fork lifted into a container, driven overland to a seaport, craned onto a ship, craned off a ship, goes through customs, delivered to Felder USA, then trucked/freighted all over the county prior to final delivery to the customer. Any and everyone of those hand offs is a prime opportunity to be jostled or bumped out of alignment. Some machines land at the owner in great shape, some not so much. Having Felder come in and commission will get the machine within Felder's tolerance, and they will spot any missing or defective parts and it's just a portion of the cost of stepping up to this sort of machinery.
