Andrew,

Nice!

Have you considered filling in the engraving to give it more contrast?

Thanks Robert, not really, it kinda looks vintage like this, in the sunlight or day time it looks nice. If i colour fill it what would you recomend?

There are far more experienced people on here in regards to color filli,
maybe some of them can give some materials and techniques to use.

There are a lot of techniques used by our members. Personally, on wood, I use nothing but powder paint. I don't have a pic, but I used black powder paint on this same project. I turned up the power just a smidge more than normal when I over-glazed it. This caused some of the paint to actually vaporize leaving an inconsistent look that was very vintage.

Hi Tim, can you give me step by step on how to do your powder paint method. Also where can I get it Locally in Toronto.

Thanks andrew

Ok today did a second one of the declaration, this time with 0.001 spot size, and same settings as the first. Not much diff, maybe should have backed off the power on the second one as it was more intense burn due to the 0.001 lens. They still look cool though.

My Powder Paint technique is in this thread: http://www.sawmillcreek.org/showthread.php?t=140683&highlight=%22powder+paint%22

I bought it at Harbor Freight about $4 for a quart jar that you're not likely to use all of in your career.

Is this the stuff used for powder coating?

That looks very nice http://www.sawmillcreek.org/images/icons/icon14.gif - even though I would go with color fill also, but I like that natural look also.

@Tim, that powder paint - is that the same what is used for powder coating ?

Andrew,

I didn't realize Xenetech offered the necessary collimator to achieve a 1mil spot size...




Andrea, yes, powder coat...

Thanks Andrea, I did two of them so maybe I will fill one of them! How about shoe polish? I here that it works well, and also on marble and granite too.

[QUOTE=Dan Hintz;1516657]Andrew,

Hi Dan, yes they have the 0.001 which I just got. They have had them for a while, the standard lens that comes with machine is 0.003 spot size. They also have a larger one than that. I don't have that one yet!

Dan Hintz

...the standard lens that comes with machine is 0.003 spot size.
It comes with a 1.5"FL standard? Interesting... most of the other systems come with a 2"FL lens as it affords more leeway in focusing for most materials. I wonder what made them choose such a short FL as standard...

Andrew Mammoliti
09-19-2010, 12:50 PM
Hi Dan, Let me clear it up a bit, standard xenetech lens is 0.003 which is a 2.5" distance to table, the 0.001 spot size is there 1.5" distance to table and the 4" one is i can't remember the spot size? there distance and lenths of lens are diff. than ULS or epilog and the such.

I question those numbers, but I have to leave at the moment, so I'll have to revisit this when I get back...

well that's what they tell me. So I really can't say more about it. I don't think they would advertise it incorrectly?

Hi Guys, trying to paint fill one of these they are walnut pre-finished but the paint seems to still get in the plaque somehow, I can't get it out either, only did a fews lines of it, so im ok for now, but how should I do the rest?

Thanks Andrew

Too late now, but BEFORE you engrave, the grain needs to be sealed. Masking sometimes helps, but if the grain is too open it isn't enough.

Hi Tim what can I seal it with next time? Spray?

Tim Bateson
09-20-2010, 7:26 PM
I don't have a one fits all answer, but some options are: paint sealer, thick coatings of varnish/poly, or wax to name a few that come to mind. I'm sure all of the experts here have their own favorites. Personally I try to stick to tight grained wood when possible.

There is a method here that calls for waxing after you engrave, then paint filling. I can't recall the thread, but it was sometime in the last year.

I've had my best colorfill results on finished wood which has been sealed after engraving with liquid floor wax. The purpose of the wax is to prevent the paint fill from bleeding into the grain of the wood. It is easy to clean using mineral spirits.

You could also use various clear spray finishes but then you are refinishing the entire piece.

Andrew Mammoliti

What kind of liquid floor wax? Is it a spray on?

Andrew Mammoliti
09-24-2010, 11:45 AM
I lasered the pc. then sprayed it with sealer, then paint filled it, cleaned it up, the sprayed to seal it. It looks good. Better then the pics show.

I think it is looking real good! Color filling is a lot of work with so many words.

Hi George, it took me less then 5-10 min to colour fill it. I used a method found on here. It worked great. :)
