laser cross hair for plasma table

[_Ogre]

Laser X hair bracket.dxf

i posted this in my table thread but thought it ought to go here too

i made a cheapass laser cross hairs for the plasma table.
everything mounts on the torch head of the hypertherm powermax 65


cut this


folded it like this


and mounted it like this, the tabs are threaded 1/4-20 and welded in


i used 2 cheap 5V 650num Red line adjustable focal length laser that i found on ebay. $7 for 2 shipped from china


for power i used an old pc power supply that i had laying around.
yellow wires are 12v, orange wires 3v and red wires are 5 volt; easy peasy
the power supply needed a draw on it to work correctly, i add the 12v bulb just for the load
it's just wire tied to the center support under the table


i control the on/off with the xbox controller shoulder buttons.
preset functions for mist and flood coolant turn on aux outputs 2 & 3 on the candcnc box.
a little tweeking of the bracket with a die grinder gives me a true right angle locator for material

powermax 65 and 85 machine torch is all i know for sure
it even has the keyway for the gear drive that nobody uses
of course you could always modify the hole for your torch

Here is a laser cross hair I made for my table I have a Hypertherm 65 Machine torch on my DIY table.
These are HF lasers about $5. each no wiring needed, worked for finding the edge of the metal too.
Single screw holds it on easy to install and remove.

Acourtjester,

I really like your design. Might I enquire as to where you purchased your lasers? I like those better than the ones I have.

Thanks,
Allen

Here you are I just removed the magnetic base and used the pivot screw to mount it to the aluminum ring.

that looks easy enough to make. from harbor fright site "Requires three 1.5 volt button cell batteries (included)."
3 buttons stacked make 4.5 volts. if you have to change batteries often convert them to the pc power supply.

Thanks for sharing looks good.

Ogre, Thanks for sharing your design. I'm always impressed when someone draws 2d for something that finishes up in 3d and especially when it's a tool that makes things simpler or more precise, which your idea does both.

That said.. I gotta hand it to Jester. It's a super clean setup. I don't have a milling machine though, so I may have to come up with something in between.

Here is a DFX file for the holder with the offsets for the mounting bracket of the HF laser.
ID is 1-3/8" for hypertherm PM65 machine torch and Trafimet machine torch.
Have fun

Thank you for the file. Picked up 4 of them lasers at my local HF earlier. 50 mile drive so didnt want to chance one being bad. ..Was fixing to measure the offset so I could draw one up and try to cut it from some 3/8" aluminum I have. Then seen where you posted up.
