Want to build a plate marker

[HammerDownJustin]

Okay seen a few here and getting ideas. First off I'm on my second home built table and thanks to Hypertherm and CandCam they have run great. Now wanting to play with a occasional marker. I really like _Ogre's set up a bunch.Going with either electric or air not sure which yet. I have one of each sitting in the tool box. Having a idea on a home built slide. What do yall think about using a air ram to push up and having the scribe spring loaded to where it goes down if the ram doesn't have air? Just thinking it might eliminate a extra regulator and then only need a switch to activate the cylinder down.. just brainstorming

Figuring out what to type when on ebay. also looking at these.

Mine is this opposite it has a internal spring for return. One regulator to push down and another for the scribe.
But your a DIY guy go for what you want.

This is a good one. Only 3 inch travel but you could work around on mounting setups. Yes more can be good, but there are way to make this one work very well (IMO)

you 2nd ebay link is the one i'd use if the 50mm slide is enough
it has flow control valves built in, less to buy



i use one pneumatic 5 way valve and one regulator on either air or electric
the regulator controls down pressure (5-15 psi), the scribe ran full pressure; both hooked to the same outlet with a T to the regulator
the scribe has a speed control built on the unit
i used flow control valves to control the up/down speed

the scribe post processor turns the air on/off for each scribe line, so the scribe goes up/down a lot
i wished i knew more about modding posts, i'd turn the scribe on and down once and use the z axis movement for line segments

that said... i've tried slow line feed, double lines and repeat scribing over the same lines
even in aluminum the scribing is too light to be of much use, you have to hold the material in the right light to see it
we had high hopes for scribing part numbers and logos on tags and welding them to exhaust systems
we never use it, maybe a rotary dremell would work better, i believe kkroger uses a router for most of his engraving

i did extensive scribing of our company logo into the side of the pc cabinet
no one ever notices it

I was wondering how a cheap Mini die grinder,(Fits in the standard torch holder too) with something like this in the collet..
Cheap enough to try one.. I got my mini die grinder setup now with a bit..(not the e-bay bit ) More for a different effect while marking..

1/8 collet or grinder would open up the bit selection ..

Thank you for the help..forgot where this post was at..lol court I like your idea better on a spring upward and Ogre I think i will go your route on the electric scribe since I have both here but can replace the electric one cheap and quick if it messes up..well when it messes up in our world.

[HammerDownJustin]

Reread your update on the electric so might change my mind on that route.. was thinking might be cool to scribe sometimes. Then run some black dye over the writing and wipe it off real quick..then do the copper patina over the top or vice versa just do make it pop a little
