Nick L - please could you give details of your microswitch/ VFD set up? It sounds interesting.

John

So I have an album here, https://www.model-engineer.co.uk/albums/member_album.asp?a=48822

I have the microswitch on S1 one connection. So when the switch (normal closed) is opened, it stops only the forward direction of the motor. Reverse direction still works . I set the VFD to stop in about 0.3 seconds I think, maybe 0.1 seconds. When the switch opens, the motor stops, then I switch to reverse, wind back.and can take another cut. The microswitch is set on a movable stop to set it in the Z distance.

Will add more to the album when I thread cut next.

Gary,

I can get quite a good grip with a Torx wrench - might be worth a try,

Gary,

It's 'Uni Screw'. I bought a box some time ago. The idea was that one bit would cover a range of screw sizes. Needless to say, the bit has long gone.........

I'm trying to upload a photo of the box.....just hang on.

I did a search on line and found a firm that makes the screws to order, but never got a new bit. I'll have a dig to see what I can find.

Rgds,'

Hi Carl,

Steve Cox (landylift @AOL.co.uk 07836 736496), advertises on the Homeworkshop site. He is excellent at this and his vehicle can lift 1000kg. It probably won't be cheap, given the distance, but you can be sure it will be done well. He will also position the machine in your premises, rather than just dump it on the drive. I have no connection other than as a satisfied repeat customer.

As a cautionary tale, a friend of mine had a lathe moved by a pallet company..........they dropped it, and the ensuing insurance debacle is still ongoing.

I have found this to be very effective: Hallet Oils Rustpro 410, available from Hallet Steam Oils. No connection etc.

I'd go for the Diamond toolholder - see the sidebar to the right. Easy to sharpen, easy to adjust. See the many discussions re carbide vs HSS in this size lathe.

Hi Shaun,

Is the Grimsby event hosted by GCMES? I'm too far away to make joining worthwhile, but would be interested in a one-off visit for your talk.

Thanks,

Thanks all for the advice and thoughts. Today I silver soldered the parts together. I fluxed the mating faces and inserted tiny lengths of rod into small cut outs that I had formed using the corner of a diamond wheel. I held the whole lot in a sacrificial spring clamp and heated it. When the rod melted the parts were forced together. So far all seems fine - it is still hard enough to bounce a file off, and has survived several tightenings. But I do know that I can get a new one if this fails!

Thanks again,

John
