Thanks Tony

Project for the day
A piece of Australian Cedar with a cut time of 3 hours 90 degree bit. A plug for our sponsors, three coats of shellac some burnt umber glaze, a light sand and a bit of a buff. I'm happy with the way my machine is cutting.
Cheers All

Nice work Kim
Really like the way the grain of the timber worked out on the dress and makes it look like folds of the material.
Mark
PS what feedrate was that done at?

Thanks Mark. Just went in to check my feed rate as I normally don't change from my default setting but change it on the fly when its actually cutting. So it says I used a 90 degree V bit 20mm and I don't have one of them listed in the database. Interesting, must have been left over from a previously downloaded project

Quadcopter
I got sick of making components for machines and I have wanted to get into flying RC quadcopters for a while.
After buying some off the shelf stuff and realising its limitations, i cranked up the updated CNC and churned out my own design (Ok heavily based on units already out there)
This is what I came up with so far.
Eagle.JPG
The base is aluminium and the top plate is G10. If anyone is interested I have found a great supply of G10 in large sheets. They also stock Bakerlite board. He has some offcuts and is in Thomastown. One colour only for the G10 (Green) and Brown for the Bakerlite.
I used one of the carbide burrs that I got from one of the CNC BBQ's and man does it cut the G10 well. I had it humming at 1500mm/min and it was no where near top speed.
I learnt that normal 2 flute non carbite cutters in this stuff is hopeless. The tool got red hot in 5 seconds and smoked the shed out. Anyone want a slightly stuffed 6mm cutter!!
Will post a link to the thing flying when it finally finishes uploading to youtube.

Cool quadcopter, maybe I should build one myself as I keep getting in trouble for flying my son's that he got for Christmas, lol. Lots of fun though, just gotta keep it away from the dog...
Cheers.
Russell.

Well I have finally hung a clock on the wall.
Been working on this one since the start of the year, new girlfriend and house move slowed progress down. I wonder how long it will take before I make a proper weight up.
This is build from plans from Wooden clock plans and complete kits for scrollsaw and CNC with a few mods.
This should get me motived to get my big free standing clock finished.

Nice job
MDF and plywood? You got his hardware kit as well? What is the pendulum rod made from?
Lot of question I know but I do like your clock

The back and front are made from MDF, all the gears are cut from "aircraft" ply. I changed the plans so all the gears had three spokes.
The plans call for both 6mm and 4mm ply, I only had 6mm ply so I had to skim some of it for the 4mm parts.
Hardware is from the local hobby shop. all the axles ride in flanged 1/8" RC car bearings.
The pendulum is made from 4mm carbon fibre rod, also from the local hobby shop.
You can buy direct off his website and he emails the plans. I haven't ordered any physical parts off him before.

Finally got my machine running and have made a few things, The work crest and a goanna. I am still waiting on some bits and collects to arrive so I can really give engraving a go, I'm just using an old chamfer bit at the moment.

CNC to the rescue---pot simmer plate
Hi
SWMBO was having a problem of trying to get a very low simmer on a large pot on the stove top. Even on the small gas ring on lowest setting the content kept on catching in the centre of the pot.
So Me and a cad/cam package and the CNC mill to the rescue.
20 minutes to think out the design and draw it up- Had to have indirect heat to pot there- no holes over flame and a air gap under pot, it could not slide off the stove top when moving a pot, so it has 4 sets of tab that cradle the pot supports.
3 minutes to make gcode
5 minutes to set the mill up with stock- 3mm aluminum
5 minutes to CNC cut it out- 3 mm cutter
5 minutes to bend the tabs and clean it up
So 40 minutes later and works a treat, Quicker them buying one and a load stronger
Why do this, you ask
SWMBO now thinks this CNC stuff is good to have around.

Here are some more of my solar adventures. First is an aquaponics setup run on 12 volt solar.
DCP_1404.JPG
The panels are at 32 degrees and fixed to a patio tube framework as seen from this underside view.
DCP_1343.JPG
To make up the jig for welding I CNC'd a 32 degree slot into a piece of panel. 75 by 5mm flat bar was then cut and welded using the jig.
DCP_1334.JPG
The battery and control box is a gutted meter box with a CNC'd panel. Typical of me the wiring is messy and something I will have to tackle later. By machining the panel you can get things laid out neat and engraved at the same time. I haven't got the hang of the new forum but if you click on the photos they enlarge and you can see the detail better - I bet you all knew that.

For those that haven't seen aquaponics the fish supply the nutrients for the vegetables by pumping the water through the growbeds. Normally the fish are eaten but we have decided to have goldfish as SWMBO couldn't stand the thought of eating her pets.
The port hole covers where machined and reduce algae growth in the tanks. As you can see the plant growth is vigorous and no problem with overcrowding.

Another solar system I have is running garden lighting and a pond waterwheel that I showed some time back.
It is run on a timer same as the aquapoincs setup.
Again I machined the switch panel and this time hid the messy wiring behind the panel.

While the subject matter is a little OT it does demonstrate practical applications on using your machine.Cheers,
Rod
