The best hand hacksaw blades I have ever used and now the only ones I will use are made by Bacho in Sweden, I have found they last better and cut better than even Eclipse.

Is that Model Engineer or Model Engineers' Workshop, as I have been looking for Workshop since the publication date and it has not been in any of the Newsagents, that I have tried.
Thread: Motor oil as lubricant - corrosion?

Car engines have phosphor bronze bearing and valve guides, so I would be surprised if engine oil would attack bronze. 
Thread: Centring a rotary table horizontally on a mill table.
13/08/2010 15:46:47
I am not sure if this will help but here goes.
I have recently completed a machining course at a local college and we used a simple but effective method for centring a rotary table on a vertical mill.  We measured the diameter of the centre hole and turned a piece of material down to fit it with a slight chamfer on the leading edge to aid fitment into the center centre hole, at the other end we turned it down to fit a collet.  We then fitted the alignment tool we had made into the appropriate collet in the mill head and adjusted the the rotary table until the tool fitted the centre hole of the table, then just to check, we rotated the table 360 degrees while the alignment tool was still in the centre hole of the table and the mill head rotated with it.  We then checked the set up and it proved to accurately aligned within the tolerances of the mill, so in future the set up can be repeated quite quickly and easily. Also the axis that are to be locked up can be done so while the alignment  toot is holding the table in location.

So the question is which of the Chinese machine importers gets their machines from the best factory?
