Having read that mandrel shafts are easily bent and being the type who likes to be prepared, I looked them up and was shocked to find replacements cost nearly as much as a new mandrel- so: as I would be passing near to a metal supermarket depot this week I took the mandrel with me and called in. "No problem" said the guy it's 6mm. "Are you sure not 1/4 inch" says I, "no" he replied, can sell you a 3mtr length for £6. Quick calc tells me thats 12 shafts so 50p each and I can always find a use for 6mm bar so smiles all round - except it doesn't fit. Theres a small amount of play in the bushings.......ARH
Lots of swear words later I dig out the micrometer (which I should of course have done in the first place) and find that:
The shaft is actually 6.20mm so I guess it's within tollerance of a 1/4" bar and the new 6mm bar reads 5.92 What a plonker I am and doesn't say much better for the guy at metal supermarkets.
Back to the drawing board.
