    Regarding seals we used the white packaging foam with a vacuum pump on a jig on the table Saw, so it could well work on the faceplates?!
    Just a thought!

    That's a good idea Charlie. I've got some laying around somewhere. Definitely cheaper than buying neoprene.
    For now, though, I've got a nice big chunk of 2mm closed-cell neoprene to put on the first couple of cups. I'm still not sure that 2mm is quite thick enough, but I'll see how it goes when I get to that stage.

    Meantime, I just gave my boring and tapping jig it's trial run. Works really well, and no risk of breaking my scroll chuck Tommy bars now.
    I made this jig for two reasons - first I wanted to thread blocks larger than 50mm sq/dia, but only have a 50mm scroll chuck and am too lazy to mess about with a glue block or tenon on these. The jig allows me to bore any block from 50mm to 100mm sq.
    Secondly, this alleviates my concern about running either the Forstner bit or tap into the bottom of my scroll chuck.

    In use, first the block is placed in the middle and the two arms are swung in against the sides and locked in place. With this design, the arms always stay parallel regardless of the size of the block.

    Next the headstock is brought up, the block is slid to the centre and the live centre wound in against it.

    Finally the 4 Allen head grub screws are snicked in to clamp the block firmly in place. They each have a point and slope slightly downwards, so they tend to grab the block and pull it down against the faceplate. Also, for the grub screws, there are tapped holes in the arms to suit the various block sizes from 2" to 4".

    I bored a 6mm x 50mm hole in the side of the faceplate to take a screwdriver which locks the faceplate to the bed while tapping. (Just visible at the bottom of the thread tapping pic.)

    This is a 95mm sq block.
    Boring the hole, (lathe on slowest speed):

    It turned out surprisingly well balanced and doesn't jump around at all while boring, even at my slowest speed of 600rpm. I'm glad I put in the effort. Another useful little jig to add to my growing collection.

    Thanks Dave. Incidentally, that's your tap in the pic. My new one arrived today, so I'll post your's off to you on Monday morning. The 1" BSW sold quickly, too, and the $ will cover your postage, so you get it as a birthday present.
