Thread: Some CNC router projects.

Nice work Gareth
I soaked mine in old engine oil for about a week. Wasn't worried about the finish which isn't too bad anyway but more about stopping the collets from rusting.

After a few hours to finish off the wiring for some new Gecko G251 (machine really moves now!) this is my second project. A stand for a RC battery charger. Designed in Solidworks, used CamBam and Mach3. A quick sand while it was still in a panel, snap and trim the holding tabs and jobs done. Thought I might have had to spend hours adjusting the slots but the fit straight off the machine was PERFECT!
A couple of small errors. Move one slot 1mm and radius 4 corners and will be very happy.
The flat back panel is for some engraved text, or maybe rebate a perspex window, engraved and edge lit with some LEDs.

Hi Gareth,
Quality work.
The slot and tab construction is popular and CNC works well with this type of design.

Hey just another request , my BIL wanted me to replicate the sticker on the boot of his mates VL Group A Walkenshaw Commodore. I tried with aluminium but painting the colours so close was a pain so I also did a reverse carve perspex which is a great result, would be ripper on the car for a few years anyhow as I think the sun would see it deteriorate over time.Also including a photo of the sticker I had to work off.

Cheers

Gary

PS : best part is I get to hand deliver in Darwin, going up Saturday for a week will be better than cold ol Perth

If I had a Walkenshaw it wouldn't go out in the sun unless it had an umbrella.

Nicely done as usual and enjoy the trip.

I make a few fixtures and jigs and this one is a little different. It is a ballnut gauge to measure from the centre of a ballnut to the mounting point on the machine.

Simply fix it to the ballnut with the two tapped holes then square the gauge to the fixing point and mark with a sharp pencil. You can then measure the distance from the centre of the ballnut to the fixing point. Note the centre line of the ballnut has been engraved on the gauge thereby not having to judge where centre is. The camera flash has made the line look wider than it is - 0.25 deep with 60 degree V Bit.

Art Fennerty (mach3 author) is developing a new program called Gearotic.

I have been having a play with it.

Some helical cut gears.

Hi Greg,
I have been following his progress in the forum. I would love to make a couple of his way out designs but can't think of a use for them.

Nice work.

Nice work.

I think you need to make a clock Rod I really do.

Good work Greg are you still using that gearbox A axis.

Yes, I have made all sorts of things on it.

Hi Sean,
You need to see some designs he has done.
I was referring to his way out designs and not standard gear trains - they are puppies in comparison.
Link is here

Something a bit more complex.

I would not know where to start if making these manually.

Hi Greg,
My mind is going overtime thinking of an application. I reckon a gear train operating a lock to a box would look really cool. The geartrain could sit behind a sheet of clear perspex so you can enjoy seeing the gear movement and the pivots can be stop drilled into the perspex. It would need a conrod to operate the lock and a crank to operate the gears. Sort of like something from National Treasure.

Fantastic work.

Fantastic work.

Steampunk jewellery box or Port box now that would be cool you would need to make it out of brass though.

My mind is now going mad with ideas thanks a bloody lot guys!
