My generation? We can only afford hand drills, hacksaws and files!

Wes, my heart bleeds for you
Keep working though - it's your taxes that are paying my £687.16 monthly pension which enables me splash out on such luxuries as a milling machine.
Seriously though, if you need anything making on a milling machine, give me a shout.
-
@deckingman you may have just opened the flood gates Ian LOL, I still want a mill and a lathe for that matter

Doug - That's on my list too. In fact I'd have had one by now if the model I fancy was in stock.
Also, the same applies to you too - if you want anything milling, give me a shout.

What lathe model do you target?

Well I'm not 100% decided but this is the one I'm seriously considering https://www.warco.co.uk/metal-lathes-metalworking-lathe-machine/303313-wm-180-lathe-dro.html.
Like the mill, all these machine come from one factory in China, (Sieg I believe). There are a few re-sellers here in the UK but essentially they are all the same machine with maybe a different paint job. The Warco version seems to come with quite a few accessories that other vendors don't offer and I have no complaints about Warco's service. The machines are set up, adjusted and calibrated here in the UK and a full range of spares is available. The tail stock on that lather is MT2 which is the same as the mill so I can use things like drill chucks on either machine.
We used to have a company here in the UK called "Myford" which had a very good reputation but unfortunately they are no longer in business (couldn't compete against the Chinese prices I dare say).

Thanks for the link!

Well, my first bit of milling for about 48 years didn't turn out too bad.
6 (3 pairs) of new aluminium motor mounts (XYUVAW axes) to replace the plastic printed ones.
-
@deckingman ha ha couldn't resist a pythonesk reply, you left the gate wide open!
Cheers though, I shall bare that in mind. I've a few ideas maturing but need to gather thoughts a bit more.

Those parts are looking good Ian. Fly over here to the states and I'll get you a job working here in the machine shop where I work

@timcurtis67 Thanks Tim but sorry - wrong part of the world. Now if you were in Australia where my daughter lives, I might have been tempted
-
Fantastic,
I have a Charter Oaks automation. Physically similar.
Also, I made the same decision: DRO, not full CNC. It's been VERY productive...
-
@danal Thanks. Coming from you, I'm reassured that my decision not to eventually turn it into a full CNC machine is justified.
The only thing that I'm finding is a bit of a PITA, is that I need to produce some sort of dimensioned drawings to work from, and as up until now I've designed everything exclusively using OpenScad, this isn't as easy as it could be. I need to look into that. -
You can make cut in OpenSCAD, then export them as DXF, and load them in LibreCAD (very good software)...
Or switch to something much more powerfull, like Onshape/Fusion360 (not open).
-
@fma Thanks, I'll give that a try. My current method is to import the OpenScad file into Freecad, then use an add on to make dimensioned drawings. It works reasonably well but I think what I need to do is just get to grips with some other Cad package and cut out the OpenScad step.
-
If you don't mind the cloud part of Fusion360 its hard to beat the value to feature ratio of integrated CAD/CAM.
It is a bit tedious to export openscad -> freecad -> fusion just because there are no common formats between openscad and fusion though.
-
@bearer Yes I've tried Fusion. It's a big learning curve for someone like me who has never used anything other than OpenScad. But then, so is FreeCad and probably all other CAD packages.
For the motor mounts, I just exported an image from OpenScad, printed it, looked though the OpenScad code to get the dimensions, then just scribbled them onto the printed image. Slightly better than the back of an envelope sketch, but not much........ -
I think that when you learn the basics, Fusion workflow is much easier.
For those mounts, did you just use the same thickness as for plastic ones? -

For those mounts, did you just use the same thickness as for plastic ones?Ref, Fusion - you could be right but I've got a lot going on at the moment so finding the time the time even to learn the basics is not easy.
I did use the same thickness aluminium for those motor mounts as the plastic version. They are 5mm thick and I realise that I could have got away with using say 3mm thick aluminium, but then I'd have had to change many dimensions to get the motor position in exactly the same place in all 3 planes. And I'd likely have needed to get all new bolts because the current ones would bottom out, both in the motor and in the extrusion Tee nuts using a thinner plate. (Edit - and that's 8 bolts per mount x 6 = 48 new bolts).
-
I was actually guessing that you kept the same thickness. Because of all of the reasons that you mentioned, that is the simplest way.
And I am curious about the stiffness gains. OK, on your printer it is going to matter, but on smaller ones? I have a feeling that plastic could be good enough.
