When I was setting up my machine in the fall of 2015, I had a number of challenges, I eventually checked all the tolerances of the machine against the guaranteed accuracy that was listed on the...

FYI here is the difference between the original Tailstrock GIB arangement and what I ended up with.

In mine I had to fix the alignment and had the surfaces precision ground and then use a precision shim. The GIB retention plate was also too flimsy. ...

I would have to concur with n1tr0;

My experience has been in line with his and the machine as it arrived in October 2015 was not a quality machine. The issues that I have had mirror that of n1tr0....

While the attached article is 60+ years old, I believe that its just as valid for a modern CNC machine as it was then:

Ok so that is one opinion, I wonder how many people will machine anything on a new or used machine for the first time without for example checking the run-out?

I am also curious as to what the...

I am curious how many reading this post have actually measured of verified the tolerances of their machines?

I had already looked at that, but the material the fan is made from is too soft to really accept a setscrew. It has a molded keyway and the easiest thing is making a small sleeve. A piece of CPVC...

I have just gotten around to powering up the VFD and Lathe motor only, and noted that the fan on the end of the motor was touching the fan shroud at the end of the motor. There was a screw missing...

I think the most grief would have been eliminated via not buying Shopmaster/Shoptask's latest offering in the first place.

In hindsight I should have packed it up right away in early NOV 2015. But as another poster on here N1tr0 noted, the return policy mandated that you had to keep the machine for a full year. Initially...

I have not done a statistical count of the number of bad screws encountered, but I would guestimate that upwards of +20% should have never made it into the machine.

I tried doing deeper holes at first. the improvement was marginal when I tested it again.
Part of the reason was the very poor quality screws supplied with the machine that were undersized and an...

The problem that I noted was that the Gib is triangular profile and exerts downward force on the plate when the Tailstock cranked in generating force with a center or a drill. This caused the center...

I cut my eye teeth on a wrench and was a gearhead long before I became an engineer at 30. I am still a gearhead at heart; I get the understanding that N1tr0 and others (now silent, but...

The opening that was closed up on at least 4 machines, mine, N1tr0's and two others, were not " the factory left open areas in the casting in non-structural places to reduce the weight" they are at a...

Just a note. many of these "Tail gate Struts" are not just gas springs but also have one way dampening that limits the speed of opening and not closing. This may be contributing to your difference.

After I received my machine, the initial problems I encountered with the Z-Axis Stepper motor and belt misalignment lead me to look at the whole setup including trying to tram the mill.
I decided to...

I had the milling carriage and the several other parts precision ground at a shop that specializes in rebuilding machine tools.
