Ground flat stock - or The importance of double checking.

[Peri]

Needing a piece of steel for a jig I ordered this - Indexa GFS Gauge Plate 15x5x500

The important bit of the specs was this

Stupidly, I assumed it would be perfect - it's gauge plate, after all.

So I cut it to length, drilled it, test fitted it, and it wasn't even close to fitting.

So finally now I decide to check it



And it's bowed

 

[bourbon]

Did it com with a certificate of conformity? If not, Your fault for assuming you would get what you pay for

 

[Peri]

I know its my fault.

 

[deema]

Its face ground, not ground all around and the width is within tolerance.

 

[Peri]

Width tolerance is +0, -0.2, every surface ground.

 

[deema]

My bad, your absolutely right. Cromwel are a good company, I know it doesn’t help with what you’ve done, but give them a call they will sort it out.

 

[Peri]

My intention wasn't to rubbish Cromwel - just to point out that you should always double check

 

[deema]

If it makes you feel any better, I would also have assumed it was to spec. and motored ahead With it coming from a reputable company. From China, I don't believe anything, only that it looks like some form of metal! And check everything I can.

Cromwells blurb does state " both ends saw cut and every surface ground flat. " For information as to what is acceptable I would contact a manufacturer like Gauge Plate Supplier - ISO 9001 Approved | Sheffield Gauge Plate so you know it is wrong before contacting Cromwells who are a retail outlet.

That's a brilliant link - bookmarked.
