You can get these splitters in various combination's quite cheaply. Could be modified to your exact requirements easily perhaps ?.

Hi Robert,

I had some of the Guinness last night, just to get into practice for the 17th, all I can say is that when it comes to drinking the Irish certainly know how to do it. 

Try this one - It needs to be done with a fine engraving point 30 degrees or finer.
I used a 40 degree on this sample and it lost some of the fine detail on the front wheel. The finished piece will be on brass sheet, mounted on mahogany.

I look forward to seeing your prancing moose, painted Ferrari yellow of course.

Hi Robert,

After the prancing horse's 1st and 2nd in F1 today this one rather amused me.

Hi Chris,

Could be a noise issue - check that you haven't pulled off a ground connection cable somewhere.

Hey Chris,

Could you explain this a little more please. I am baffled.

It looks like the top photo has the toolpath running horizontal wheras the other photos look like the toolpath is vertical to the piece.
Surely if the stepover was the same then all phots would show the lines, wouldn't they ?.

Nice job SF.
Keep on grabbing ideas from the forum - that's what it's for.

Hi High Tech Key,

If you are switching your spindle on / off with a relay which does not have adequate arc suppression (across the contacts) then the noise spike generated may well crash your computer.

SSR's such as this one, switch at the 'mains zero crossing point' and produce much less noise. They can be driven from your existing relay and just require a small power source.

Hi Gaz,

I think it is like all the stuff from China - you don't know if it's any good until you have it in your hand.
Most of the stuff I have purchased from China has been of excellent quality, but not all, so beware.

Hi Jammerm,

Some litho's were made with Mach1Filter some with CamBam and others with Bmp2Cnc. BmpBender may also be suitable but I have yet to try this for litho's.

Looking forward to seeing the results from your machine.
