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

Looks good but pretty certain you wouldn't catch my fingers in the slot with the tool that close while in cycle!

Yes not a practice I'd recommend....in my defence I've run the simulation 20+ times so knew it wasn't going to rapid on me anytime soon....however I'll agree, no excuse :hopelessness:

Good stuff Neil.

Was that a Fusion 360 part or i-machining?

One method I've used to avoid faffing about with zeroing off of a part like that is to cut a holding fixture in the bed and then use the same zero to then run a contour pass(es) to clean up the part.

Of course you know Jazz is going to turn up soon and goad you into cutting deeper and faster ;)

Cheers Chris, it was Trochoidal machining in Estlcam. I've not really messed with fusion 360...downloaded it and installed it but I use Geomagic at work so until I get more proficient at that I'll not confuse myself by using two 3D programs....

I'm going to give the bed another surface soon and at some point I'll put the 1" thick bakerlite sheet on and use that as my surface and tap holes into it for holding down workpieces but use sacrificial wood as necessary...

I'll not need much egging on by Dean...I started at the speed and feed that was recommended for the cutter...onwards and upwards!

Chris, what tape do you use to hold stuff down?

Just finished the Mk2 mount....could have been a Mk3 but this will do! Did put some engraving in the middle but got the depth wrong and it snapped the engraving bit :dejection: Still I forgot the hole in the middle for the shaft to go through (manually drilled) so that would have gone through the engraving anyway....Pressed the tubes into the plate on our hydraulic press and at 2.5 tonnes pressure I don't think I need to use the Durafix to weld them in...might do it anyway but I'll see. The bolts are pulling the tubes into the plate so they're not going anywhere, just the torque twisting them. Might get a big block of Ali and mill it out of 1 block though I'll probably not bother if this works...

Guessing it's for a belt arrangement for something?

Bet your loving having a cnc up and running you can make stuff on, I can't wait :).

No it's simply a spacer to hold the motor off the firewall so the propeller sticks out the nose the correct amount...

Yeah I'm loving it, just starting to be more adventurous [emoji1] get it finished Lee it's great fun...

Ahh right it's for a plane!

:) I will it's just a waiting game really, mechanically all I need for it now is two gantry side plates, two bearing plates and 3 motors, Dean is lined up ready to make the plates for me but I can't commit just yet as money is tite but I'm working on it :).

In the mean time I've been getting a few bits together for the enclosure, I'm actually ready to go with that side of things but again with out motors to connect it all too there's no rush so to speak.

I've just had my second injection for this new biological medicine they've put me on, I had my first one last week and the next morning I could feel the difference instantly when I tried to first stand up, normally I'm on steroids and painkillers during the day and the roids have been a great help in getting me some what mobile again but when I first wake up obviously those have all worn off through the night so I normally have to give my legs a min or two too adjust then go for it but as soon as I put weight on my feet (mainly the ball of my ankles) it's painfull, it's quite funny really because obviously as a man the first thing I need to do when I open my eyes is drain the bishop! But I can't because it's a painfull struggle getting to the bog lmao, it's been close lmao quite a few times as I've been bursting and needing to go asap lol

But as I say the future is brite and the morning after I stood up and to my amazement there was nothing there pain wise and since I've had no pain at all I really can't believe it, the doc said it would be 3 months before I would notice it starting to work, I'm not complaining!

Today I've been for a walk into town to get my hair cut, drop some packages off (switches for the lads) and get the girls a McDonald's for their dinner (brownie points) and I've made it back as happy as Larry because it was easy (normal).

Sorry I'm waffling on your build log but I'm just feeling so positive at the moment and i really cant wait but i really dont care either, what's more important in life as basic as they maybe is what I'm chasing at the moment :D.

Positive: Don't worry, my day will come and CNC better be ready for me 😎

Hi Neil,

Sorry - missed the question at the bottom - I use this tape:

Silverline 198134 Fixman Double-Sided Tape, 50 mm x 33 m from Amazon

Glad you're on the mend and things are getting easier for you to do normal everyday stuff...that's great news!

Hopefully things pick up a bit now and you can crack on with the build, look forward to seeing it!

Cheers Chris, I'll look at getting some...would have made machining this much easier!

Here's the bracket after I've made a mess with the Durafix, machined 5mm off the tubes (lathe) and bolted it to the firewall....only got 2 bolts in at the moment but WILL have all 4 in before anything electrical gets connected I promise!!!

Attachment 18404

Put the nose cone on and fitted the prop (18" diameter x 8" pitch) to see what it was like...

Attachment 18405

***high pitched voice***
SSSWWWEEEETT!!

I'm just starting to do the things I should have done before using the machine (Sorry Dean!!) and one thing is a touch plate (limit switches are also going to be dome ASAP) as I want to use Ger's 2010 screenset. Now I'm a bit thick when it comes to electrickery so I wanted to check I was doing this right before even cutting a wire.....

My limited understanding is that I can connect the -VE 24V DC to the tool via a croc clip (or can I permanently connect it to the spindle or frame?), the touch plate is wired to the -VE input (15 in my case)of the CSMIO IPM input and then I put +24V DC to the +VE (1 in my case) input?

Is there a better (correct) way to do it? Sorry for my stupidity :stupid:

Right or wrong it works, installed 2010 screenset and used the simple tool zero and yep......it works!!! Had the bit loose in the collet just in case!! Bought a trepanning tool from Wealden as recomended by Dean and set the height to the base and took 1mm off the bed (it's really bad!!) Felt some ridges so tweaked the spindle right by 0.2° and the bed seems pretty smooth now...

Attachment 18492Attachment 18493

Just need to do the limits so I can home the machine and put the fixed tool change plate on (when the new bed is on the machine!) and make the frame....dust extraction unit....put electronics in the box....etc. etc. etc. etc............:hopelessness:

Hi Neil

That looks like a nice cutter - might grab one myself when ordering from Wealden next (I've been very impressed with their routing bits etc. to date).

I always thought trepanning was used to relieve headaches by cutting a hole in your skull - learn something new every day :)

If you have the tool grounded via spindle/frame, you may permanently connect the 0V of your 24V PSU to ground. Then you have only the touch plate wired as you already did (but not pin 1 and 15, eventually 1-14 or 2-15 :playful:).

I find very useful the "Probe Active" green led on the 2010 screenset that I also use. I made a habit touching the tool with the plate every time I use it to make sure it is working as expected.

The easiest and rapid way to find the corner of your workpiece (nonmetal) is by using a "triple edge finder" (or a double edge finder that is easier to make yourself). To find the center of the touchplate hole that corresponds to the corner of the workpiece you have to use the excelent '2010 X-Y Probing Wizard'.

I can tell you one thing....there's no way that I'm using that bit to drill a hole in my head!!! However it does surface the bed beautifully :biggrin:

Oooops....you are correct, luckily I've got it wired 2 & 15......:whistle: Yes got the 0V wired to the frames earth so I just had the one wire to thread through the cable chains....

I don't fully trust it at the moment so like you I check the connection every now and again. I must admit that it's been a complete revelation this screenset and the touch plate, it's spurring me on to do the home and limit switches ASAP now...

I was thinking of making a corner touch plate, now I think I will....got some Ali plate somewhere to play with :biggrin:

Well last weekend I flew my plane that I made with my router....so this is a look what I've made on my machine post :)

Pity it wasn't a glider - must have been some good thermals under those clouds!

Well done - great sense of satisfaction in building something using a machine you built yourself. Nice landing, too!

Cheers Neale, the wing loading is such that it can thermal, it's a real floater. It was satisfying telling everyone who asked about the plane that I made it from scratch on my CNC router I also made myself!

The landing was a good one, second had one hop skip and a jump [emoji15]

Neil Beautiful job. You obviously can fly as well. Brill.

Brilliant job!
The sky was very cinematic too, you couldn't have picked a better backdrop for filming,

- Nick

Lovely job well done. Those high wing trainer types are very relaxing to fly.

Jealous now as I haven't been flying for several years. Must get on with that Spitfire project ! . . . . after I've finished the MK4 router, and the house jobs list, and, and

Cheers chaps :biggrin:

The sky looked brooding....1/2 hr later and it was a clear blue sky (but was sitting down having a sausage and bacon buttieAttachment 18716 Attachment 18717, an hour later and it was tipping it down again :thumbdown: Wasn't the best video as it was taken on my mate's phone...must get a GoPro (or equivalent) so I can strap it inside/outside and film. Would like to go FPV in it for a laugh :biggrin:

Cheers Barry, that's what I wanted, a nice floaty relaxing plane....next one is another trainer type but for a 0.25 glow motor to scream about the sky and practice my inverted flying etc. etc.

I've still got stuff to do on the router...home switches, limit switches etc...someday!!

Nice work Neil looks great, lol to the info on the switches.

.Me

Ok so Friday I started the frame to mount the router vertically, finished it off today including paint. It wasn't the all singing and dancing one I first planned as that would have been far too heavy to move. This will have a wood enclosure eventually to stop plastic/wood/metal chips from flying about as well as a dust/fume extraction system in it. Lots still to do, tomorrow will be putting the control panel on the wall and at last putting the electronics inside it! Anyway, some photos of the frame and router mounted.

Looking good Neil I will be looking forward to see how it pans out in use.:yahoo:

Great stuff Neil - bet that felt like a big milestone reached.

Will be nice to see how it runs in its new configuration.

Chris

You and me both Clive. Will be interesting when I fire t up again tomorrow. Need to make some rubber bump stops asap to park the gantry at the bottom safely...think I have some polyurethane rod somewhere.

Cheers Chris, it's a relief and will spur me on to get it finished now.....till something else pops up.

How about those round rubber door stops with a hole in the middle? https://www.google.co.uk/search?q=ru...HcJvCbMQsAQITg

Good idea Clive.....the stops have to be about 60mm (will measure later) and I think will have to be rectangular....more research needed I think!

Control box & VFD on the wall....

now working on the electrics.... got the correct tool out....

Neil Do you think you will need another bracket to bolt the frame to the wall at the top, shimmed as to not twist the frame:applouse: Hope you are only using he hammer to tap the connections into place

There are 2 additional bolts half way up bolting the frame to the wall...shimmed with custom cut bits of pipe 😁 the base is shimmed and bolted at all 4 corners so I'm hoping it's still all square....will tell when I first go to cut later today...

http://uploads.tapatalk-cdn.com/2016...954c5595e8.jpg

Hammer was, as you suggested, to tap in the wires...who needs screwdrivers?

Quick video....

https://youtu.be/F7W9s0fFaG4

Don't seem to be able to see any chips though:thumsup: . Just thinking aloud how about a brake operated with a solenoid that operates when you lose power. It could be on a counter weight steel cable over the top (on a pulley) and then brake the cable.
