|Thread: Cheap ER collet advice please|
As ER collets can be used for both tool and workholding, not buying a set is a false economy.
I bought an ER32 chuck to use on the mill, and intending to get a bolt on chuck for the lathe, bought a full set of collets. The collet chuck was such an improvement that I quickly gave the Clarkson clone away, and bought the lathe chuck. 12 years later, only one of the collets is still in its plastic wrapping. Some of the rest haven't been used much, but it beats having to stop work for a few days to get a £5 part that should have been bought as part of a set.
I use the collet chuck for drills when doing jobs that combine milling and drilling. I'm tempted to buy extras of the common ones I use to keep with particular tools, like the edge finder, to speed up changes. I find the idea that hobbyests don't need to work quickly and efficiently very strange.
Arc's Stevensons collet blocks really simplify milling/drilling operations on round parts.
The ball-bearing nuts are such an improvement that I bought another pair so that each chuck has its own and the blocks share the third.
I have a set of ER11 collets to use with my toolpost spindle lashup; I'm very tempted to convert one of my MT blanks into a holder to use small drills in the tailstock.
|Thread: An interesting repair to an Hour Wheel|
Unsightly not hideous, but certainly clever.
I wonder how long it has been like that?
|Thread: A cord of Ash|
I know of one local ringer who makes their new stays out of ash trees he cut down some years ago.
We're currently paying about £20 per blank, but they're Hastings stays on big bells.
|Thread: Metrication of models|
What utter drivel! No one's eyes and brain are naturally calibrated in inches/feet/whatever, they're just trained to do so. 2400mm is as visualisable as 8 feet, it just takes the same amount of practice. And bumping it up to the next used measurement(there's a good reason to go straight to metres from mm) doesn't need any calculation either.
I hope that's high on Neil's list for the bag of nuts.

Metric fuel consumption is measured in litres per 100km not per km, because it gives a sensible, rational number. Just like miles per gallon, rather than gallons per mile.
|Thread: Any interesting lathe projects for beginners?|
It's just making an internal sharp bit!
Seriously, that would be a good reason to make one(two, three -however may it takes to get a satisfactory part), and you'll use it most times you turn on the lathe. First thing I made for and on mine.
Why not have a look around the house?
New handles and knobs for missing/broken ones on furniture are a good start, either to match existing or replace them all. Not long after I got a lathe I made a new handle from aluminium bar to replace the broken plastic one on the chest freezer; it had been broken for years so won me some brownie points. I'm currently fixing a damaged waiter's friend for my sister; it's not worth doing, but it's part of a set that was a present. Bazyle is right about the G-cramps, we have lots that were thrown out because the pads were missing, it only takes a few minutes to return a £30 Record clamp back to use. And because it is already well-used I have no qualms about putting it to rough use.
My 80 year old Dad still opens letters with the opener he made at school, and they make tea with the caddy spoon I did.
Making parts that don't matter is a good way of improving skills and learning what the tools can actually do.

|Thread: Stuck oil filter|
A stout leather belt and doubled up sandpaper is another way.
|Thread: How to upset the neighbours!|
Perhaps you would prefer this:
3.0l V6 and manual gearbox from a Vauxhall Omega.
|Thread: Tool post project|
I think you've gone backwards: that's added a lot of extra machining to each toolholder - you need a lot of them, so that's important - that doesn't justify its existence. That's why I like John Stevenson's suggestion to reverse the dovetails on a more traditional style post, and put the male dovetail on the holders.
The main reason for using a QCTP is to quickly swap lathe tools. Even a simple part could need 3 tool changes(face and turning, chamfer, parting tool). Height adjustment is just a natural part of the drop in design of most of them. The OP's design doesn't have that, so the tools will need shimming the first time they are fitted. This will be much easier to do than trying to machine each holder to suitable dimensions.
The thing that makes them quick change is having enough tool holders handy, so that once a tool is set up, you don't need to take it out of the holder. I have 13 for my Dickson copy so far, and buy a couple more each time I buy anything from the various suppliers.
If the post needs to lift to change each holder, why not replace the mounting post from a nut to a cam operated lever like a bike axle?
|Thread: Mini mill or handtools for this job (rectangle with slots)|
They're fairly simple to make, but on such a small mill will take ages compared to the cost of buying them. Time better spent on actually using them.
|Thread: Help milling an angle|
Interesting that you think 3mm sheet is 'thin'
I reckon you're going to struggle bending it with the design you're building, which does work well on the 0.8mm I use for most car bodywork repairs. Your vice won't 3mm either!
|Thread: How useful is a 2inch machinist jack on my Sherline?|
I made a pair when I bought the mini-mill because they looked useful. They never have been.
You're over thinking this. Buy some material, and make some of it smaller and round. That will teach you what you need to know, and what you ought to make/buy.
|Thread: Things I should know cutting various materials on lathe|
You'll find it a lot more efficient to buy a few pieces of the material you're likely to use and just try them on your machine, with your cutting tools. Brass, steel, aluminium and whatever plastic you have in mind of about 25mm diameter won't cost you much. And once you've made a few cuts you'll be able to make something, rather than just worrying about it.
|Thread: M4 x 0.75mm pitch CSk machine screws|
Is anyone really going to screwcut such a thread when they can buy taps and die?. Anyone who gets work done, that is.
|Thread: Home built trailer|
It's not a guarantee, but it does mean that the trailer(car, van whatever) has been inspected by a disinterested party and so have any necessary repairs once they've been made. This is one of many reasons why the MOT exemptions for classic cars is a terrible idea, although not as terrible as some of the repairs that owners do only when forced to. Having such a test would also force some of the maintenance that many trailers have never had - I recovered several that wouldn't have caused their crashes if simple jobs like greasing the wheel bearings or replacing time expired tyres had been carried out. Expensive caravans or car carriers aren't immune to that either.
|Thread: Flat bottom hole 3/16 o/d|
I normally use a milling cutter for flat bottom holes, but none of my 3/16 cutters are any where near long enough for a 1" deep hole
