Thread: Some More CNC Projects

Now that I have worked out how to post images, here I go again
Here are some more projects I have cut and engraved on my laser.
The first two are and indexing dial for laying out clock faces on unusual shaped timber pieces made from 3mm flouro acrylic.
The third is the bottom part of a one twelfth size welsh dresser for dolls houses. made from 2mm plywood.
Hey Greolt and RodM there is no stopping me now.

Good posts Len and keep them coming. I would like to see some crystal etching and ........

Had some issues with the plastic router plate I was using to mount my Triton Router in my router table. Had a look at some of the commercially available plates and decided to make my own for substantially less dollars.

Machined this plate out of 6mm ally and also made some inserts to suit a variety of bits out of 3mm ally. I engraved some lines on it to show the centreline of the bit to assist in setting up fences, etc.

Thought it may be of interest. Forgive the photo quality, they were taken with my phone

It's.just a.drop in plate secured with counter sunk screws? I mean you didn't make the insert use a clock arrangement?

Hi Mike

Yes, as you say, the inserts are just drop in plates secured with a countersunk screw. I'm not clever enough to make them twist in and lock in place. This system will work for me. I'll just have to keep a screwdriver and some spare screws handy for those inevitable times when I drop one in the sawdust.

Geoff,

If I recall, when I made mine with the CNC I cut a circle and left a groove/lip a few mill thick. Had to machine the groove on both sides of course, so I flipped the plate over on dowels. Then I removed some of the remaining groove for the camlock plate to fit in. Easy enough. However I did use the camlock filler plates I had from the poorly made phenolic plate I bought - what a waste of money that was.

Good idea putting alignment lines on the plate.

Great plate Geoff and nice idea Mike for making the cam loc system.

All that's left to do is making the stand alone z axis which will be your router lift...lol. I am sure most of us have thought about doing this so that we can have our own version of an MLCS router lift.

Having just bought some blank router plates from Woodhaven, I think I've found my first real project for my CNC router (if I ever get the damn thing finished ...)
Still looking for ideas on the inserts though.

First real project on the cnc, full of 'learnings'. I now know 86 ways (and counting) of stuffing up a bit of wood with a cnc. But It is getting better.

The base design for this, is from a post on the Vectric forum. I have modified it a bit, to make final assembly a bit easier. I have also fitted the back a little closer. In addition, I replaced the original base, with an additional tray.

Wood is Tassie Oak, with Mebau handles.

Hi Chris,
Beautiful piece - I bet that get's you some brownie points.
Was the inlay on the lid done with CNC?

Thanks rod. I bought the motiff, and just machined the pocket on the cnc.

Don't know about the Brownie points though, I reckon it's just got me into strife. I posted the picks on facebook, and now my 2 daughters want one, which is fair enough. What I didn't count on is the 2 sisters, and 9 nieces, all putting their hands up.

Nice work, I like that.

That is a very nice piece of work. Well done

Cheers

i need some large battery packs for some projects and ordered what i needed of ebay

these LI-Ion battery's will be 4 battery's in series , with 8 packs per brick , and 8 bricks , each group of 4 battery's needs a Li-Ion battery management board (8 if them ) a switch to brake the voltage down to its charge rate of 18volts , and a set of terminals for each group (8+,8-)

my main computer is out of action with a mystery problem so i have fired up my spare CNC pc , and it will not take my TurboCAD software , so i drew this up in "Vietric's CUT2D " , (easier than i thought it would be)


as a newbie , i have some questions

1) if you have to machine both sides of a board , what's the easiest way to locate centre again after the flip

i have drawn 2x 2mm holes , at X0,Y-223 , and at X0 , Y223 , ( with 0,0 centre ) will drill these holes deep into the sacrificial sheet so after i flip the material , i can screw it down in 0,0 , is there an easier way ?

2) braking the machining in to a few steps will let me drill the screw holes , then fill them up with screws to hold them in place before cutting out the shapes , how good to tabs hold on "impact resistant perspex " , and tabs need cleaning off after ? any ideas ?

3) the lettering , not sure how the letters will turn out with a 2mm bit , but a V bit wont take the centre out cleanly , what's the best font for a V bit ?

so the attachments are
1) photo of the bits
2) screen shot of CUT2D
3) CUT2D file
