That said, this won't be just a build log, but will also detail and modifications that happens in the future.
The package arrived yesterday, and I spent an hour and half to roll around in the parts(checking that they were all there) and starting on the build.
Tools...
The 13mm wrenches will come in handy. I only have 4 of those hanging in my garage.

The 5/16? Drop forged? I think I'll stick to a proper Chrome Vanadium 8mm, even if I only have 2 of those.
Pliers are OK.
The thin screwdriver I can imagine getting some use later, too. Bl**dy difficult to find so long screwdrivers with such a narrow blade.
The Allen wrenches are OK. Not the best quality, but then again, I lose these at an alarming rate anyway, so best quality is wasted on me. They're longer than most I've seen, and again, that's a plus.
The M5 tap. I do have a tap already, but this handle is more compact and nicer than the one I have. Big win.
Beginning assembly.
Putting the wheels and idlers together was easy... Too easy in fact; some of the bearings slid in without any problem. That I foresee to be a problem later, at least with the idlers.
Then I started on the Y-axis idler.
Methinks there's a problem with the holes as the eccentric spacers won't fit the holes.
Didn't fit on the Y-axis motor mount, or the X-axis plate, either.
No problem with the Z-axis plate, though.
Also, there's a problem with the M3 washers. 3 of them aren't M3 at all, so I only have one left after fitting the X and Y motors.
(I may have some somewhere in my office... I've needed an excuse to tidy that room for a while, anyway... )
That was yesterday...
Today sees me with a round file...
Fitted the 6 missing eccentric spacers and wheels.
Tapped one slide and mounted it.
Seems I may have messed up the threads in one hole... I'll pick up some longer M5 bolts tomorrow or saturday. Then I'll also pick up a box or two of Nylock nuts.
On the the MAkerslide the X-carriage moves on there's one slot along one side and two on the other side.
Should this slot be towards the top or towards the bottom?
(Picture doesn't show) Or doesn't it matter?
