Mill Tramming Complications – Debugging Help Required

Conducted some more tests this morning as per the suggestions.

One side of the table is lower than the other, but only by 0.02mm over the whole length.

The head-raising test using a square was repeated, this time;

• With the square clamped to the table
• Test was conducted at the centre of the tables
• Gibs were locked before each reading taken

Results were roughly the same (0.6mm over the height of the square [~200m,].

So I've emailed Warco to see if they can provide any insight.

I'll post a copy of their QA sheet when I can find a moment to locate it.

Yeah the QA sheet could make some interesting reading in light of the reality.

I don't think .6mm per 200mm can be blamed on shipping or installation misadventure.

0.035mm apparently!

They could win the Nobel Prize for fiction with that.

Totally agree, from personal experience I don't believe any of these generic QA sheets issued with budget tools & machines are worth the paper they are written on!

Even if it was "within their spec" it wouldn't be great – 0.05 per 100 mm ? Even a budget industrial machine would be expected to be around 0.025 per 300mm.

It is unfortunate that the customer is expected to do the final inspection on new budget machinery to determine if it is within specification, as even budget machinery is not cheap these days. I think it is unreasonable to expect that a hobbyist without experience could know how and/or have suitable equipment to do such an inspection.

Right. And it's only now, after owning the machine for over a year, that I'm coming to know the machine well.

The clincher is that the warranty is only 12 months.

Lee, under British consumer rights legislation the 12 month 'warranty'  does no absolve the retailer from selling an item which is not 'fit for purpose' they are duty bound to fix it, can't remember where you are based?

Sunny Brizzle!

[Tony Pratt 1Participant @tonypratt1]

Guess that's Bristol, I had to Google that one.

I did check that it was Googleable before posting.

Yes, Brizzle is local slang for Bristol.

[Lee Jones 6Participant @leejones6]

No reply from the website query I made, so I called up Warco.

Ended up speaking to Roger (the owner).

They're going to collect the mill and repair it for me.

Thanks for all your help chaps, I really appreciate it – as always.
