Comments sought on new build: A CNC Router for RC Gliders and Planes

[njhussey]

I was thinking along the lines of this, but measuring it is just over 2000mm long so might have to re-think it...oh and before someone comments I know it will have to be a belt and not a piece of string

[Wobblycogs]

Nice bit of string you've got there ;-)

Looks like your coming to much the same conclusion I did. I'm sure a belt will work but it's certainly a long belt. I decided I'd rather use two steppers and have the open back that I could shove long work out if needed. Feels like one of those six of one half a dozen of the other decisions.

[njhussey]

I'm not planning on being able to shove long work in and out, won't be practical anyway as I'm limited by the roof and floor as mine's almost vertical. I've just added some bracing to the legs so that's made the cutting area smaller with my previous width of Z axis....so I've narrowed it. I'm hoping that it's not too narrow, it's now 145mm wide. I'll have to check the 15mm carriages but I think they'll be ok at that width...

Just been looking at PV solar panels, leisure batteries and charge controllers for the shed so I can have some 12V LED lighting in there as well as being able to charge my RC LIPOs etc...interesting little project

Broken the different frames out and coloured them so they stand out a bit more, also did it with them all together.

I've got a friend who's PV mad, he's just bought a load of panels so I can ask him what he's got if you'd like?

[njhussey]

Yes if you could please. I am looking at 2 leisure batteries 115ah each, 2 x 100w panels and a 20A charge controller. All in about £250.00

I've got two 92Ah 12V batteries that I'd consider selling. They're these ones:
Enersys PowerSafe 12V92F - 12V 92Ah VRLA Battery £0.00 - Industrial Batteries - High Rate VRLA - Enersys V Range - Front Terminal FIAMM Batteries | C&D Technologies Batteries | YUASA Batteries | Enersys Batteries | Scooter Batteries | Lawnmower Batte
I've barely used them, but had them a while. I've charged them every few months though to stop them degrading. No idea what they're worth..

For the solar panels you're best off looking on eBay. A few months ago I got four new certified 190W panels for £120 each, then another two the same for £100 each. They're now on the shed roof and grid tied with an inverter also from eBay.
