First mod is in the area of backlash.
The two slides are fitted with adjustable nuts (good) but at the handwheel end its not so good. I will be using the ARCeurotrade Myford cross slide type fix to see if I can improve the backlash. Currently its about 0.2 mm
Also fit DROs
Will_D:
So first bit of cutting last night. Pretty impressed so far. Motor is quiet thanks to the belt drive. Some cutting noise comming through the bench.
Anyway some overall impression/notes so far:
Tool set is missing a 1 mm hex key for the gibbs
No t-slot if front of table for table stops. (Was obvious in photos so not a criticism)
Even though it has anti-backlash nuts the handwheel end is not good and needs improvement
A printed table scale would have been nice on the front of the table like on the Z-axis
Y axis feed screw is protected by the design of the apron - no need for bellows
The digital speed readout is correctly calibrated to reflect Spindle speed
It came with 4 M6 tee-nuts (not all do!)
All in all am delighted with the value for money.
Just need to sort the backlash!

Will,
I was referring to something like this fellow did.

Perhaps your mill is constructed differently or it is not necessary as it seems to be performing well, and that is what is important.
Thanks,
Hans

Ah I see! Thanks Hans. I must check the drawings for the various mills!
Still its warner reading indoors than in the garage!

Hi Will,
I have the exact same model mill as you. And as Hans has said I had a miss alignment of the spindle axis to the Z column. I spent a lot of time with shims on the column before I caught on
:Doh:
The way I found to check was this
1, mount a dti in the spindle
2, place something with a good long right angled side on the table
3, measure the dti reading as you move the head up and down
With mine I found the reading stayed the same which meant the column was at right angles to the table. So the error is in the alignment of the spindle to the column. To fix take the head off and you will find the dovetail casting is bolted with 4 cap heads to the spindle casting, slacken off and you can twist the 2 castings alignments. If you nip the bolts and refit the head you will be able to correct the spindle to column with gentle taps with a rubber hammer as above. When correct tighten the bolts fully and the jobs done
:D
