    Dividing head Chuck “through-bore” size

    Hi. May be a stupid question, but I am wondering if it is possible to get a dividing head for a mill that will take a 40mm OD tube “through the Chuck”? To machine 5mm holes at 120degrees at one end of the tube. The tubes are 1200mm in length. I currently use a slip on tool with pre-drilled...

    Grinding wheel specs for Fibreglass/Carbon

    Hi, we run a Malcus centreless grinder in the production of fibreglass and carbon fibre tubing and I’m looking to go about replacing the grinding wheel on the machine over the next few weeks. This is a job that hasn’t been done on this machine with 20+ years so I presume it is well overdue...

    Bridgeport series 1 2J2 x-axis trouble

    Hi, The x- axis leadscrew in my Bridgeport turns when both handles turn but only moves the table intermittently. As in it seems to have a mind of its own. It will engage one minute while you crank it and if you stop to crank the other way it won’t engage. Any help would be greatly...
