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

My calc is giving me 24,000rpm, 4000mm/min feed with hard plywood and 6mm 2 flute carbide tool, max depth slotting of 4.5mm

Obviously I don't know what you'd use on a CNC (yet) but if you were routing by hand with a 6mm bit you'd use the fastest router speed (24,000 rpm usually) and take 4mm deep cuts max. Feed can be anything fastest enough to prevent the bit from burning the timber. By hand and with a jig I'd guess I'd be doing about 2.5m/min but it's mostly done by ear. If you can use a 1/2" straight bit you can go much much faster they are nearly indestructible in wood.

Cheers guys, ill reduce the depth and up the speed, Graham I managed to snap a 1/2" bit 😁

Ok so old teeny 200 lph water pump with head of 0.45m wasn't man enough anymore so splashed out a whole £15 inc next day delivery for a 1400lpm pump with 2m head.

Just made a acetal adaptor 18mm down to 8mm...

Then a couple of acetal joiners as the pipe was now too short for the new tank...

New 4 gallon cold water storage tank with lid and Bob's your Uncle....new bigger cooling system 😁

Comparison of old pump and new pump....

Put a cyclone in before the CamVac (just because I had it rather than need it) and its brilliant!! Takes out about 95% (guess) of all crap, fine dust as well....

Cutting plastic so you get a good belt from the static when you go to empty it 😁

Chips in the cyclone currently being generated from these I'm cutting out of 18mm sheet Acetal at work...

Bits in the cyclone...

Bits in the CamVac, was a new bag...the stringy bits you can see were already there 😁

Hi neil

Thanks for the post on my log - I placed the order for the bits soon after posting the video!. Also great idea to use a cold water tank for the spindle cooling system. I found when I was running in my spindle for about 3 hours that the water in my 10 litre bucket was tepid at the end of the period.

regards

Mike

Hi Mike,

No problems, glad it was useful! I've been really impressed with how efficient it is. If you cut plastic don't forget to earth the bin!

I was finding my 5 litre water tub got pretty warm after a couple of hours cutting and had one of the 4 gallon cold water tanks left over from putting in a chemical blacking line at work so decided to use that and upgrade the pump whilst I was at it.

How do you find the noise on the Camvac?

Pardon???!!! 😁 its quite noisy, I'm going to put it outside when we build a store, it gets loud after running for a while.

That's what I thought. A quiet, powerful vacuum that can filter fine dust would be a fine invention!

You can get a silencer for it, think of people who grow things in houses where they don't want others to hear.....😉

Finally got round to putting the CamVac outside. Work are building a storage/outbuilding and its now out there...much quieter now!

Also putting in an extraction system to take smoke away from lathe (still got to plumb them in) and milling machine, also plumbing it into the router cabinet to take away balsa dust etc. that the dust shoe misses.https://uploads.tapatalk-cdn.com/201...c277f434c8.jpghttps://uploads.tapatalk-cdn.com/201...f96ba2adc3.jpghttps://uploads.tapatalk-cdn.com/201...1b77cef2db.jpg

Hello all, sorry not been on here for ages (years it seems!!) My CNC Router has been working away successfully for a long time now making RC plane parts and plastic parts for work...still not finished and the jobs that needed finishing off before still need finishing off. As Dean (Jazz) said you have to do them at the time else you'll never do them!

Been busy with work and recently replaced the Warco GH1322 lathe we bought a few years ago with an XYZ 1630 CNC lathe so been having fun with that. Only had it 2 (working) days so just getting used to programming it. An XYZ 500 LR VMC is the next purchase this year to replace our Warco GH Major round column mill.https://uploads.tapatalk-cdn.com/201...24c8811f7b.jpghttps://uploads.tapatalk-cdn.com/201...6ba47bfa7d.jpg

Do you mind me asking where in the Uk you are as I fly/build big gliders too. I'm up from the North, Lancashire. Spent many hours out out on the moors flying into the sunset out over Belmont way. Certainly would be a great contact to know you as there isn't many who share the same interests that I know!

Hi RobC
There are quite a few of us on this forum who build and fly RC models and gliders. I'm one of them too! Here's my build and a picture of wing ribs I have cut on my machine

Hi all.....been a while as work has been keeping me rather busy. Now we're in lockdown I thought I'd pop back on to see what's happening here!

I no longer work at Howdon, so don't have the use of the router, therefore I will at some stage be making another CNC router but this one will be a real lightweight affair to use in the house just to cut balsa and 3mm ply!!

Hope you're all keeping safe and well :eagerness:
