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

[JAZZCNC]

Can't do it at home as no 16A sockets :(

Just bang an old nail in fuse it'll be ok for a few hours welding. .

It's one of them new fangled fuse boxes with little plastic trippy things so you can't wrap tin foil round the fuse or bang a nail in.... :(

Got an electric oven? That will probably be on a 32 amp radial. I'm clearly not suggesting you pop the isolating switch off the oven and have the wire running out of your kitchen window. That would be irresponsible.

Andy, for a nano second I did think about it ;) .....however I'd have to have some sort of beefy extension lead going to the shed as it's a good 15 meters away from the cooker! I did think about getting a 5.5kv genny too but the cost was too much as I'd not really use is and its a new build so all the houses are crammed together so the neighbours would complain... simple solution is that I'll weld it at work, we have all the kit as it's what we do here!

Neil, I've really enjoyed reading your build thread. Nice to see a few fellow RC guys on the forum too.

Have you thought about building a vac-bed to use with your machine? With the thinner, light-weight material we modellers tend to use, a few people I know have found them really useful. With your machine being vertical it might be even more of an advantage?

My plan is to build one that can be used for cutting thin sheet materials but also removable for machining thicker materials.

Si.

Hi Si, thanks for the comments! It's not much of a build thread at the moment, more of a rambling design changing exercise...however I've now got nearly all the components (the steel came in yesterday) so I'll actually be starting the build soon

I have thought about a vac bed but I just want to get the build done. Will probably have one that can be put on the bed and taken off for other stuff (just like you) but how soon that gets done remains to be seen!! I also want to build a Vac former (for canopies, cowls etc) and a CNC 4 axis foam cutter for wing panels....already accumulating bits for the foam cutter

Well as Jazz says I've stopped fannying around with it and cut the first couple of bits of steel to length so it's all go now at long bl**dy last

Going to cut the rest of the steel before work and during lunch over the next few days. Hoping to start welding it up next week. It's going to be bloody heavy, I'm not looking forward to lifting it on my own as according to my calcs it'll weigh 74.4kg.

Will update with pics once I've started the welding as pics of cut lengths of steel aren't all that exciting...
