A few more more pics.......

Both X & Y axese adjusting strips had grooves caused by the edge of the dovetail not being deburred properly...... Soon filed away.
Also spun the adjusting screws in the lathe to file to a "drill point " angle for better location in the dimples.




Silky smooth slide.....





All oiled & greased, leadscrew nuts positioned, baggy handwheel handles bushed etc. ::)

Ready for tramming.......  :thumbup:

David,

An hour or two spent setting the machine up correctly before you start using it, will be repaid with many years of satisfactory use.

These machines are invariable faily well made nowadays, but slung together by untrained erks, and can be made very accurate by doing just what you are getting up to.

It is when using the machine straight out of the box that problems are encountered. And of course the suppliers get slagged off for selling unstable garbage, when it is usually the buyers fault for not fine tuning it.

Well done.

John

David,

Very nice looking machine. Looks very simular to my Grizzly mini mill.

Question? From the pics I see that it uses inches on the scale so I'm assuming that the dials are graduated in thousands of an inch?

Now if this is the same as my mill I'm wondering if the lead screws on the machine are 16TPI or 20TPI. Here's the reason I ask. Go to my website and check out my page on the Mini-Mill. You'll see what I'm talking about.

Regards,
Bernd

Thanks for your positive comments Fellas.....

Finished setting up today!!   :headbang:


Bernd,

Thanks for your link, I haven`t seen that one before. Will give it closer inspection!

My screws are 16tpi. With the drive slot....... And it`s a heck of a long way from one end to the other!

Don`t really fancy a finer pitch, just yet......  ::)


The Y axis was out by .008" high to the front.



I slipped a 1/4" wide strip of drinks can alloy, under the front of the column & re tightened the capheads.
This gave me one an a half thou...... Don`t remember which way...... That`ll do, for now!  :thumbup:

Got the X axis to .001" over it`s full table length, via the column nut.  :D



Time for a bit of bling (my version)......

That gear lever`s blummin `orrible!  :scratch:




Short throw, GT version!  :thumbup:




Hmmm....... Hadn`t spotted the remaining red grease!  :doh:



It all feels silky smooth & ready to go......  :thumbup:

Gonna make some chippings tomorrow....... Re machine those T nuts, probably!  :clap:

David.
