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

[JAZZCNC]

I started cleaning up some of the welds but there's a lot of that to be done as my welding is rubbish! I also put on (at Jazz'z suggestion) a piece of 50x6 flat on the end of the rails to act as a stop for the gantry when it goes vertical.

At the moment my machine is back on it's feet for some recent repairs and I can tell you I really miss it being vertical.?
Not just for the space but for my Back has leaning over the bloody thing to fasten material has been killing me. Didn't realise just how easy it does make fastening and accessing material while it's working.
Also having to deal with clearing chips again is a pain in the arse and again you don't fully appreciate how much differance it makes until you have to go back.!!

You haven't experienced using flat so you maybe won't fully get what I mean but you will if you ever use it horizontal after being vertical. . .Lol

I'll take your word for it jazz lol I'm beginning to wonder if I'll ever get it finished. I just never seem to have any free time...

Looking forward to finishing the frame off next week, getting quite into the fabrication side of things again!

Question for people. How is the best way to DIY cut 20mm Ali accurately? I'm running out of money (wedding is end of March so bills are coming in fast!!). I was thinking of cutting the Ali for the gantry myself to save a couple of quid (plus I like the challenge!) as I don't like the prospect if telling the wife to be that we're not having a cake as I spent the money on machining... ;)

I cut 20m Ali plate full depth on my table saw using a carbide tip blade that is so tired it complains at cutting hard woods yet munchs thru Ali.??
(Wear eye protection and cover all exposed flesh has the chips are red hot and hurt like hell.!!)

For shaped parts make some MDF templates and use large router with bearing guided carbide cutter with very shallow passes.! That's how I made my first machines gantry sides and that was with a 12mm cutter.!!!! . . . Which wouldn't recommend so go for 6 or 8mm max.
Other than being a little daunting it worked a treat.!. . . . Thou I will say I was very very experienced with using a Large router free hand so if not used to routers then be careful has they can be a handful.!
