Laser Edge Finder

<< < (3/4) > >>

Yes - boatmadman, you'r right, but ...

if the laser diode is placed where the cutter comes out of the collets then the problem is eliminated - right ?

You can still have the adjustment ring in the buttom but the emiting point of the laser diode have to be placed in line with the buttom of the collet - and centered - I'll try to make one this way.

Best regards

If the laser is pointing at an angle other than vertical, or rather colinear with the spindle, the point will move depending on how far the spindle nose is from the workpiece. I guess this would be pretty difficult to set up straight unless it's already colinear with its existing casing.

Hi

In order to check for center, how would this work. :doh:

1. Place complete lazer edge finder in collet (that is known to be true) in headstock.
2. Turn Lazer on.
3. Lazer should now light up the point of the tailstock center. (If the tailstock is centered on the chuck.)
4. If light is not on tailstock center, turn chuck by hand and watch the travel of the lazer light.
5. Adjust the 4 screws of the adjusting ring as necessary until the red dot stays stationary when turning the lathe chuck.
6. I would think that 2 sets of 4 adjusting screws would be required for perfect alignment.

If tailstock is not centered then set a flat surface perpendicular to light beam and keep adjusting until light beam stays centered in same spot when rotating chuck. Change length from several inches to several feet (or as long as possible). The red dot must stay stationary at any distance or it is not accurate. :bang: :bang:

Just my thoughts on it.  :lol: :lol: :lol:


Cheers  :beer:

NickG:
Yes, was thinking about it last night and Don's method would definitely work but Andy's should also have worked making sure the dot was in the same place whilst rotating the mill spindle. Of course the more distance you can achieve that at, the more accurately it is set up.

Sounds pretty good, think I might try one of these.
