No won't affect spindle provided not constantly using it this way. In which case you would have it mounted to Z axis in it's own holder.
Re: Diamond bit drag knives
Off course.. mount it to the z axis.. makes sense and now you say it.. so obvious :)
Re: Diamond bit drag knives
I’ve just recently started using one of these engraving carbon is so much easier quicker and cheaper.
I only put a Z depth of .75 meaningless I no because it depends on spring tension.
Re: Diamond bit drag knives
What one do you use mate?
I see this USA one with 1/2 or 1/4 shank for about $180.. then a UK based one for about £45..
Is the usa one just a fancy "Made In the USofA" sticker adding
£100? :)
$180

Re: Diamond bit drag knives
I actually got mine from the good old US of A but was £56 if I recall from this seller, I’ve got a new diamond saved just in case.

But that’s pants down price for what I’m doing it does the job just fine, I’m only engraving logos and my RC name on parts.
I used to use a normally engraving bit but carbons tolerances of +-5% means engraving was a ball ache, I only engraved .1 deep so some parts would get missed that’s when the ball ache came in I’d need to re do those missing bits [emoji23]
Engraving carbons only braking the resin so not a great deal of load.

Re: Diamond bit drag knives
Oh man that look's sweeet :beer:
What do you use to add colours, just spray paint then wipe off glossy surface instantly with maybe a bit of masking..?
Re: Diamond bit drag knives
Cheers [emoji12]
I just used a sharpie pen colour then wipe off then keep doing it till it’s nice and clear, then used a Q tip dipped in petrol to get any off that dried before I wiped off [emoji23]
Re: Diamond bit drag knives
simple but effective :)
Only thing with sharpies is life span, wife uses them on jewellery she hand stamps.
bit of masking and airbrush maybe the thing to try. :eagerness:
Have you ever tried laser engraving with your cnc router? also looking at them 4w laser addons and they look quite fun s well :)
Re: Diamond bit drag knives
I only really make them coloured for sales pictures mate [emoji23]
But depends what parts will determine life it’s rc related parts gas rc, so the front and side parts stop on, the rear behind the engine if the exhaust seal goes then that prays shite all over.
We’ve just got a laser engraver at work and keep forgetting to bring in some carbon to test [emoji23]
