    Restoration of a car ferry

    Hi,

    OK, it's not quite cars, but nearly. The Raymond Island car ferry, on the Gippsland Lakes, Vic., has been taken out of service after corrosion on its undersides was found.

    Apparently when...

    Hi,

    With our ER11 collets I have notice the same puzzle, so am also interested.

    At the moment I order these router bits off eBay, usually from China, in HSS and carbide, 3 mm, 4 mm, 6 mm, and...

    Hi,

    This is correct. The idea is the machine operator (usually a thread rolling machine) can use it quickly to determine if thread size is correct, without having to make an actual measurement....

    They are only for finishing a cut in tight spots I think. Routinely I use a simple nibbler attachment to a power drill and it works very well.

    Hi,

    We have a single phase lathe on which the reversing switch fell to bits internally. We contacted an industrial electricians' company who were useless. The sparky knew nothing about it when he...

    A used one you mean?

    Anywhat, here's one in eBay. I bought a single phase motor off this bunch, and it seemed quite good (I have no connection with them, to make a pun).

    Hi,

    I agree with Michael. The trouble with V cutters in a vertical spindle machine is that the area near the tip of the V is at very much non-ideal cutting conditions, with very slow surface...

    Hi,

    I think they would be a better choice than HSS router bits, due to the cutting edge angle being relatively more suitable for aluminium than the fairly acute edge on the HSS bits. Then of...

    Hi,

    Hi,

    I think - inspect the caps for bulging, end pops or leakage, and if they look OK carry on. If the start cap is cooked, then the drill won't start unless you give it an assist (careful...

    Agreed,

    On looking around, nearly all the parallel port cards seem to be universal-type, 2 notches, 5V/3.3V. Reckon that would work OK? They are quite cheap anyway.

    It has indeed turned out to be electronic, being a faulty or below par parallel interface in the PC. On swapping the PC around, the problem disappeared, and the little machine seems to...

    Replacement lathe motor

    Hi,

    At our Men's Shed we have a Yangzhou lathe with a 1.5 kW single phase 4 pole motor which has died. It has a 100L frame which is odd in that rating, most 1.5 kW motors are 90L, a bit smaller....
