Laser cross hair tool position.

Rich,

Is your laser similar to the ones that Dave and I have (with chrome color case) or is it the one with brass color case ?.

Just curious.

Chrome color case and has laser adjustment lens. best i could do is get the width donwn to about .030".

Hi Rich,

0.030 inches resolution is no good at all - obviously not all these laser pointers are the same. I shall now consider myself lucky and perhaps buy a lottery ticket this afternoon.

Rich, dumb question but are you trying to focus the beam at all?

You do realize that the collar screws and unscrews and there is focal adjustment?

Also, distance comes into play here as well so maybe you're too close to the object?

Thanks,
Dave

Dave,
Yep, that's when adjusted. I actauly bought two of them so will have to see if the other is any better, but expect not

Ok, sorry to hear that

just my 0.02c.. why not rig two line lasers? on along X and one along Y, front and side of spindle.. same cross but 100% accurate as long as you align it to your spindle correctly?  can power both together and stil control by one switch but you lose the offset tilt  problem...

or did i miss the plot here completely?

That sounds like the professional way to do it and would of course be far better.

Because Mach handles offsets so well and because these cross hair pointers are so cheap it was a simple approach to achieving the desired result. Having used this for some time now I certainly would not be without it but I agree, it could be improved upon.

Gotcha!
