|Thread: Electrical switch for a Myford ML7|
Anyone recognise the switch set-up shown in Peter's Album, more importantly where does the wire connect ?
Hi Peter, best take some pictures of the complete set-up and place in your album, details of the motor plate would also perhaps help, no point guessing what you have.
|Thread: Telescopic bore gauges|
For checking bores for taper or ovality I use these dial calipers, any out of truth can be immediately seen, if you need to know the dimension measure over the legs with a mic or caliper at the reading indicated in the bore, I normally use a digital caliper.
David has described the best way to use telescopic bore gauges, I have a set of Mitutoyo which were bought second hand many moons ago, I find they give better accuracy than earlier posts, but then I have been using them for many years. I usually measure over the gauge with a digital vernier.
Several methods of measuring bores in my photo album, drill blanks above are simple to use as gauging the hole if you don't need the precise dimension.
|Thread: Does a 1600rpm bantam have a single v belt?|
Correction, should be 1966 model, GB World Cup winning year.
Single belt on mine, a 1996 model.
|Thread: Knurling Tool for Mini Lathe|
Might help to choose a knurling tool if the maximum diameter that could be knurled was stated in the advert, not based just on shank size, poor information from suppliers.
|Thread: Myford ML10 lives again|
Hi Dave, nice job you did there.
|Thread: mini turning|
Roger, if you only need a short length of 3mm diameter use a facing & turning tool which is ground to 45 deg angle to the lathe axis, either take 1 x 1mm DOC or a series of cuts to achieve the 3mm diameter, at the 1mm DOC you will have your 45 deg transition from 3-5mm.
|Thread: anealing piano wire|
Any modellers who started building model aircraft with the Keil Kraft flying scale rubber powered models will be aware that the simplest method to retain wheels on an axle is by soldering a cup washer each side of the wheel,
If the axle is cut to the correct length it makes for a very neat job, also best use pieces of paper as washers each side of the wheel before soldering to prevent any flux or solder tracking to the wheel, paper removed after soldering. Bazyle did suggest similar earlier.
Bazle, the junior hacksaw blades you have are much better than I have ever been able to buy, mine usually just skid off piano wire rather than cut.
|Thread: Further Adventures with the Sieg KX3 & KX1|
My method is old hat but doesn't require special tools or programs, just enter the tool offset in the toolchange line in the program,
|Thread: anealing piano wire|
Dougie, another method would be to use a Dremel type tool with a grinding disc to cut a shallow groove around the wire close to the end and use an E clip.
|Thread: edm machines|
An EDM design and build article appeared in the Strictly IC magazine many years ago, so if you have a friend with that mag collection you have another choice.
|Thread: Axis orientation (or, where is zero?)|
A lot of the work I do on the mill is small pieces held in the vice, I set the X zero to the LH side of the fixed jaw and the Y zero to the face of the back jaw.
Z zero set to suit each part but normally Z zero is 1mm clear of the job, all tools used for the job are referenced to the No.1 tool in the program so after a toolchange the tool will be 1mm clear of the job to allow fast traverse to the working position.
|Thread: What would one use this adaptor for?|
Perhaps a boring/facing head.
|Thread: Please help machining|
Looks like a job for a tool post mounted grinder, cutting something that small with a ball nose cutter sounds unlikely to me.
|Thread: Non-Drip Gloss Paint|
Chris, best advice I can offer is bin it.
|Thread: Motor control circuit|
The VFD will run OK with a supply via a correctly wired 13A socket, best to use a DP switched type to give isolation to live and neutral.
John, no volt protection is built in to the VFD ?

|Thread: Mini lathe|
Arckivio, did you check the commutator bars directly opposite each other for continuity ?
You should get the same resistance reading on all pairs.
