|Thread: Collet Chuck for my CL250M?|
Swapping the studs between chucks is daft. I loctited short lengths of studding in all of mine that didn't come with the lathe. I did the same with the mini-lathe when I had it.
|Thread: ML7 Hand Crank / Wheel?|
That's pretty normal for me; I think of M5 as small.
When I need to to use a bigger tap on my WM250 a 17mm open spanner on one of the chuck jaws works well...
|Thread: Confusing t-slot dimensions|
Also true if you have a small milling machine; power feeds and larger cuts save a lot of boring work. It's also a good way of using up stubs of material that are unlikely to be of any other use.
|Thread: Skynet is Coming|
Which was probably meant to be "Pimp".
Wrong spectacles perhaps?
Four button control panels for multi-function devices annoy me far more than unnecessarily 'smart' ones. You don't have to connect smart features, but are forced to remember which one of several complex sequences of button presses whilst singing the Elbonian national anthem backwards at half speed in a minor key changes from automatic to manual. That's dreadful design, compounded by not having a clear, hardcopy instruction manual.
Touch screens should have reduced this, but the emphasis seems to be more on making the icons look pretty rather than actual use.
|Thread: TOPIC VARIETY|
This forum's strength is that it doesn't restrict posts to a narrow range of interests.
I've been a member of ones that do, and still look in on others. They often have little traffic, or the same job is repeated over and over. Keeping them going is almost as hard work as reading them. It's like watching Youtube videos where every cut is shown in real time; necessary for a beginner's tutorial, but excruciating for anyone else.
|Thread: Dickson holder storage|
This took about 20minutes and £5 worth of material:
|Thread: Looking to learn CAD|
I won't argue with anyone that CAD programs are complicated, but that's also true word processors and spreadsheets.
What a prospective CAD user needs to be aware of before they start is the underlying concepts, both in general and how each program applies them, but I would suggest that they're a lot easier to understand than those needed for 2D drawing!
|Thread: Mini Lathe leadscrew key size?|
By the time you've figured out how to clamp it to the mill, you could have filed it to size and fitted it.
|Thread: What tool to use please|
Take the blank out of the lathe and using the angle grinder knock off the corners so it's 'rounder'
That will make your choice of lathe tool less critical because it doesn't have so much to do.
|Thread: How Many People Does it Take to Change a Lightbulb on the Forum?|
I remember visiting my great-grandmother in the mid eighties, and her cottage and her brother's next door were without electricity. Lighting was gas downstairs, and oil upstairs. Outside toilet at the end of the garden.
Fixed that for you....
|Thread: Multi-part assembly drawing|
You have that completely back to front: just explaining the conventions for representing 3D objects on a flat piece of paper takes far more explanation than being able to orbit around a '3D' object on a screen. Fusion even names each of the six faces Front/Back, Left/Right, Top/Bottom which requires no explanation, and clicking on those rotates the object so you're looking directly at it. One simple sketch can provide all the information to produce a 3D part like a single cylinder crankcase. A quick outline, constrain the geometry, add dimensions and extrude - the same work as drawing just one face. You add features like holes, slots, bosses directly to the face they sit on - what could be easier? And that's before you start on more complex operations like lofting, sweeps, sections, surfaces or moving parts that are very difficult to do on paper.
This all dramatically reduces the skills that a designer needs to create complex and/or multi-part objects from scratch. Creating a 2D drawing is then a simple operation if it's even needed at all; many parts can be made on manual machines from the information directly available from the 3D model.
I had an hour a week of Technical Drawing when I was 13, 37 years ago. That leaves me able to read a drawing, but designing parts in 2D would take me months of instruction, practice and frustration before I ended up with something usable. This model is completely dimensioned, animated with all the clearances worked out over a couple of evenings:
It means that the flat parts can be laser cut from the model, thus saving even more time.

I use Fusion 360, and do the opposite; top down, where each part is modelled in place which leads to one complete thing per file
That does require careful use of components, but you should do that anyway, and I find it much easier than trying to join up lots of separate parts. You also have to consider the 10 editable parts restriction on free Fusion use.
|Thread: Starting out a young enthusiast|
£3k on a Myford plus all the other sundries just to get an 11 year old started on his own is ridiculous. One of the smaller benchtop machines is probably more suitable, and much cheaper but spending a grand would still be easy.
So how about a 21st century approach?
Get him started with basic hand tools making/modifying parts, what they are doesn't matter. Learn how to work safely and well. That's what an apprentice did at the start of their career. A vice(one of the cheap workmate copies will do), hacksaw, small files and a means of using drills won't come to much if they're not already available.
Working on things like bikes is useful.
Meccano, LEGO technic, or similar are a good way of learning to assemble things that do something.
Download Fusion 360 and learn how to design things. Add a 3D printer to make some of them.
If he shows aptitude and is still interested, that is the time to be looking at small machine tools.
Linking up with like minded people in person dramatically reduces the learning curve, although that's not currently an option.
|Thread: Tool grinder ways|
How about linear rails?
This is what I've been considering for the last couple of weeks, combining the sliding/tilting table of a Worden, a modified version of the tool slide for an ER32 spindle, and a Quorn style post mounted, brushless motor grinder-head. That's all modelled in Fusion 360, so I intend to start on it when I can afford the parts:
I think the table and endplates are ideal candidates for laser-cutting, especially as I don't have the 3 and 6mm steel required, which should speed up construction time.
The whole thing sits on a 400mm square baseplate, that will probably be an offcut of Corian.
That picture is actually a previous version, the latest has simplified it a bit more.

|Thread: Tufnol, Phenolic, SRBP, HPL, CGL, SGL|
Several colours of overspray smudged around with brake fluid and thinners soon takes care of that....
|Thread: Engineering / Modelling Books for Winter Evenings?|
It's a bit of both. If you don't have a Myford, then it's not such good value.
|Thread: Vfd advice please|
They're meant for sanding wood. If you intend using one to shape metal, as a belt-grinder, you'll quickly discover that they don't have enough power. Like trying to use an air-tool off a small compressor.
