|Thread: Where to find a *good* optically flat mirror?|
My mounted mirrors came with certification stating the measured flatness as 3 millionths and 7 millionths of an inch.
|Thread: Shipping to the EU - beware!|
Seems to me the only thing different between you buying something in Aus and having them ship it, and buying something in Aus and shipping it yourself is the person putting it in the box. What reasoning do you use that makes it different with regards to import charges?
|Thread: Help please!|
My condolences on losing your dad it must be a trying time. I had to clear away my dad's workshop stuff and I kept some but most of it I had to get rid of.
Your dad's little lathe will have more sentimental value than monetary I would expect and most of the value is because the Myford name was made very popular by the later model 7 and it's iterations. I think that you'd do well to get a couple of hundred for it in that condition.
One thing I do see in the pic is what looks like a fixed steady tucked in the tray under the tail end of the bed. Those are not common and might be worth a few bob. I see it also has a threading dial (long vertical tube with a gear on the bottom, right by the letter F). Might be desirabl to someone.
The cover on the left end should open to expose some gears. There should be loose ones with it so they can be swapped about.
Good luck with your sale, I hope it does well but don't expect too much.
|Thread: Does anyone know what this is for?|
I think that eye bolt has a piece of rope tied to it with some kind of tension spring attached.
Frustrating having only one angle of view and most of the business end out of sight.
|Thread: tapered slots|
The plate with the slots is called a masking plate. Used for rapid indexing.
No problem Mark, whenever you can.
BTW even though the Hardinge stub gears are famous, Hardinge UK certainly used full 22DP gears I have a factory drawing for them.
The HLV rack is 42 pitches over 6" which is exactly the circular pitch for 22DP.
Sounds like a 22DP long-addendum gear Alan.
DOH!, I should read all of your post before replying. Hardinge love 22DP gears. I can reproduce it for you if you like.

|Thread: What to do with old reamers|
I've done this to ease the fit on a reamed hole. You don't get much but sometimes it's just enough to make a slip fit really nice.
|Thread: Problem with 4 jaw chuck|
Take the jaws out and lat the chuck face down on a surface plate. I bet it will rock like a boat.
More often than not bell-mouthed jaws is actually bent chuck face IMO.
|Thread: Lathe DRO|
It's unusual - almost impractical - to have a DRO scale on a compound since it tends to not be used much and even then only over short distances of less than 1 turn for the most part. There is also the complication of space constraints and the fact that the compound rotates meaning that you'll have to have loops of leads that are prone to snagging.
Most of your turning will be done in the X and Z axis, X being across the ways and Z being along them. There are a myriad of functions that a good DRO will provide with scales on X and Z.
|Thread: Gear Change Wheels for a Smart & Brown Model A lathe|
What tooth counts do you have on your end gears? The one on the stud and the one on the gearbox. The large idler is of no consequence.
|Thread: Cleaning a diamond grinding wheel|
Do you mean a CBN wheel, typically a reddy brown colour? If so just use it to grind a sharpening stone like an oil stone. If you mean the type that fits an angle grinder just use it to grind a soft brick or soft concrete block.
|Thread: Hauser watchmakers machinery|
That's definitely a Hauser (and beautifully restored). A guy local to me is rebuilding one.
|Thread: Involute tooth depth|
You can specify but for the purpose it wouldn't matter, the whole depth is the same for both.
|Thread: Faircut Lathe Advice|
£550 is about 3 times the most I would consider paying for that lathe and even then I would have to be desperate.
|Thread: Involute tooth depth|
John, it's actually half of that.
|Thread: Buffing and Polishing|
The only advice I can give is - get more power! Polishing can be pretty miserable if you're constantly stalling the motor.
|Thread: Honda 125 electrics|
The 6v Hondas had very marginal electrics and one might even have had to run the bike during MOT to get them to pass on those items (there is a facility in the testing manual for this). Also, from that era there were two different systems for the ignition. For example the OHV CG125 took it's coil power directly off the magneto so it could be run with no battery. The OHC CB100 took it's coil power from the battery however so with no (or poor) battery it would not start.
This is working from memory I hope I'm remembering it correctly.
|Thread: A home-made gear - will it work?|
If you want I will cut you a new chaser gear in brass or bronze. You can bore it out and turn your original down so the new one can be bonded to the old hub with loctite.
