|Thread: You meet the nicest people with a Cowells|
I don't think there's anything else Cowells size which does Cowells quality jobs. I have the lathe and the mill. I also have a Proxxon FF230 mill, and a Unimat-3 in a shop on another continent and have fooled around with Sherline gear in a friend's shop.

|Thread: Buying advice sought re Milling Machines: e.g. Proxxon: FF230 vs. BFW40/E vs. MF70|
I have a FF230. Same story; space restrictions. In my case I was also buying in a hurry. In hindsight I'd have held out for a jig borer, Aceira, ff500, Cowells or whatever. It works, some of the bits are reasonably high quality. The motor needs to run at higher speeds, round column is bad design (it's not that bad, but it's still bad; dovetails are better), and if the table were ever so slightly bigger it would be very helpful. Also the ability to mill at an angle .... it kind of forces you to mill at angles. Tramming is difficult and the dogs don't hold it well; I've had endmills catch on work and had the head twist over on the angle axis. It's just a friction screw thingee. Lame.

Sometimes, the internet is amazing. Here's the old classic book, online, with animations so you don't have to visualize what's going on:

|Thread: EU materials suppliers?|
Muito obrigado Sr. Costa, I hadn't come across FMS yet. There are a few places here in Lisboa which sell tools and large industrial supplies, but they're not well equipped with little bits of metal. At least none I could easily locate. You're right the language is a big barrier for me; Germans have simple english-like words for something like mild steel (along with a specification) -here, I mean, how does one say "mild steel?" aço macio?
From the French thread, these look useful:
So, unlike most of you folks, I'm in the EU (Portugal), and finding it a bit difficult to source materials for my growing workshop. Under ordinary circumstances I'd go make friends with the local scrap dealers and machine shops, but with covid lockdowns, making new pals is rather difficult at the moment.
Since Portugal has a vigorous outside-the-eu enforcement regime with their customs department, I'd rather buy within the economic zone for fiddly "need this and that" bits like this. I should be OK for brass sheet, cast iron, drill rod and aluminium rod from the below suppliers, I'm particularly hard up for bar and square stock of all kinds and mild and/or free machining steel sheet and square stock. The latter for my first project; my take on the Harold Hall dividing head.
This is going to be all small stuff: I'm Cowells-ME and Proxxon FF-230 in a small workshop. If anyone knows more good places for the EU hobbyist to pick up bits and pieces of metal, that would be great. Otherwise, if anyone is in my position, the below firms have been helpful so far.

|Thread: Plans for updating the archaic forum?|
As an actual Silly Con valley guy: all respect to Ubuntu engineers whose hard work keeps all my hardware ticking over, but beware software engineers suggesting improvements.
Oft times such folks (myself among them), with the best of intentions, look at software and think "oh I could do better," or "I could fix X thusly." Sometimes it's true. More often though, they do not understand what the existing software gets right, and the end result is worse. As a trivial example: I agree with someone above that Xenforo is very cool forum software; slick, nice UI, uploads images/PDFs with ease, nice to administer as well. However, the search feature is absolute trash. That would ruin the utility of the stored wisdom of this forum.
The human generated comment here is the valuable thing. It would be nice to have a few more fiddly little features if they can be added easily. But if this thing runs exactly the same software in 50 years in some futuristic virtual machine in a positronic brain, with 50 years more content, it's a huge win, even if you have to log in again when you use your ipotato, and the file uploader still isn't spot-on.
Probably in some timespan on a 50 year scale, the appearance and functionality of model-engineer will be seem as charming early 00's ambiance that punters will pay extra for, to remind them of when the internet was still cool and new.
Anyway, happy to help if there's something needs fiddling with. But I think you have it nailed; don't mess with it too much!
|Thread: New guy|
Thanks for the welcome and good advice guys. Not quite retired yet, got a few more years of work in me, but doing stuff that gets me away from the computer is super important to my sanity.
New guy here; been shopping for a hobby lathe, keep coming across your forum in the searches, and figured I'd join up.
Definitely a model engine in my future, and maybe a clock if I get real ambitious, but who knows how long it will take to get up to speed and tooled up. More short term is making widgets out of aluminum and brass for electrostatic generators.
Was thinking about Cowells stuff, but as I had a Unimat-3 back in the US, I think I'd rather something a bit beefier, and more locally supported (who knows with Brexit). Proxxon PD400 is kinda more in the ballpark; nice spindle bore, but it seems pretty much same thing as Optimum TU2004v, which is cheaper and which is sold down the street from my house, where I can threaten the proprietor with a bacalhau or whatever the locals use in such circumstances.
