|Thread: centec 2a riser|
Do let us know if you decide to go into production.
|Thread: It's Myford Jim, but not as we know it!|
My original Nottingham Myford fine feed cluster also has a plain bore, though the normal driver, where you can change the output gear, as you say has the needle roller and bronze bush.
|Thread: Knurling tool operation|
I watched this video last night before you posted your reply.
The presenter makes the same point very well, if in a rather long winded fashion. Fast Forward might be of use to the viewers

I'd pondered on making one of these , to Gadgetbuilder's design some time ago, but never got round to it, and then a house move got in the way.
|Thread: Royal Mail tracking|
I'm still confused here.
(or at least that someone has signed for the item.)
Was it posted by you, or to you, and under what sort of tracking?
|Thread: Alternative Lathe that would fit Myford Ind cabinet for a long bed|
Robert, if it's not too personal a question, what roughly is your budget?
p.s. Hello and welcome by the way; it's pretty friendly and helpful round here.

|Thread: Lathe belt broken|
Bob, I might be missing the blindingly obvious, since I've never used one of these lathes; surely the whole purpose of the belt tensioner is to release the tension, in order to change speeds.
Apologies if I'm sucking eggs up the wrong tree, or something like that.
|Thread: Metric micrometer what t buy?|
There are varieties available which don't have a 4" thimble.
This Starrett works as a 0-1" through to a 5"-6", so almost fits the description.
It's getting a bit tired now but is accurate at both ends, but the 2"-3" and 3"-4" misread by one and two thou respectively.

I'm glad it's not just me, I have the same problem, particularly with my one small internal mic , which is metric.
|Thread: Record 25 vice handle|
I was just about to pass a similar comment; I used a short length of thick wall reinforced rubber tubing, the sort of stuff used for air lines or gas welding bagging. Car heater, or oil pipe would do, but just make sure it has fibre, rather than the steel wire braiding often found in hydraulic pipes.
|Thread: Metric micrometer what t buy?|
Have you considered an electronic/digital one?
They are available with both metric and imperial thimbles, from a variety of manufacturers.
Unfortunately I hadn't realised until it arrived, that the fixed anvil is ball ended, so it works well for flat surfaces and tube wall thicknesses, but since your main use for it is on the mill. that might even be advantageous.
p.s. This looks to be a similar item with a different badge if the Silverline logo offends, and also has a metric thimble. They probably all come out of the same factory.

|Thread: Boring bar with inserts shape choice??|
One thought, that I don't think has been mentioned Chris; bear in mind I'm self taught, so don't always know how a job is supposed to be done.
Hence, during boring, a slight distortion of the tool will move the cutting edge into the workpiece, and thus a deeper cut, perhaps then distorting more, and leading to an even deeper cut and the eventual dig-in and or chatter.
|Thread: What would you call this tool|
Not sure what you'd call it as it's a bit of a home brew special.
|Thread: Yahoo Groups: Heads up for members of e-mail groups|
Many thanks for that, I've not tried it yet, but I think it might be PG offline.
|Thread: How does someone gauge the power of a DC or AC motor?|
From the photos you posted of the diamond laps, 400rpm seems about right.
A normal cheap 240v motor will run at 1425 rpm, so you need about 3.5/1 reduction.
Another ebay search for "NVR switch", will point you to one of the cheap black and yellow switches, so it all works safely. For the loads you're likely to be putting on the setup, I can't see the point of fancy overload/overheating protection for the motor.

|Thread: Yet another 'which mill shall I buy'|
Premier Machine Tools have a Tom Senior in at the moment; if not for you, someone else reading the thread might be interested.
|Thread: Source of Stainless Strip|
Maybe find someone who makes bandsaw blades for butchers, and blag a short length; they are likely to be stainless strip.
|Thread: Installation of a Myford (or any machine tool)|
A couple of thoughts spring to mind, Currently my own Myford S7 clone sits on a clone cabinet, but essentially all similar to original.
As a temporary measure when I moved in to the new house, where the garage floor is uneven, I use 4 adjustable height feet; essentially lengths of threaded rod, with a ball end plugged into a disk of nylon. They are plenty strong enough and easily allow adjustment for the uneven floor; I'd have struggled with lengths of box section, as I'd have still needed lots of bits of packing.
The advantages; ease of adjustment, quick, cheap, allows some storage underneath in old baking trays, adds enough height to save me bending over too far, makes it easy to move the lathe away from the wall, for access to motor etc.
Disadvantages; if something is out of balance, the whole assembly is more prone to vibration, a real pain finding stuff underneath when you've dropped it, arguably less stable, but I can't imagine it toppling forwards, and there's a wall behind it.

|Thread: Changing a Motor from Star to Delta|
Emgee, I'm not quite sure what you meant to say there, but I'm not sure it came out right in print.
3 individual windings U, V, & W, each with ends 1&2 and all end 2s currently commoned together in Star formation.
To transform to Mesh (i.e. Delta), whilst still maintaining the correct orientation of each coil, as follows.
Leave U1, V1, & W1 where they are, U2 goes on top of V1, V2 on top of W1, and W2 on top of U1
