I don't remember what is considered safe, I've been retired for over 4 Thu, 23 May 2013 01:45:50 GMT Stan http://groups.yahoo.com/group/4x6bandsaw/message/12333 http://groups.yahoo.com/group/4x6bandsaw/message/12333 Thanks for the warning Leon. What would be the highest safe wattage, I know I was kidding about the 50 MW,--- that laser on ebay is 50mw I assume that big "MW" Thu, 23 May 2013 01:31:07 GMT Leon Robinson http://groups.yahoo.com/group/4x6bandsaw/message/12332 http://groups.yahoo.com/group/4x6bandsaw/message/12332 Stan, 50 mW won't cut, but could be dangerous. That is enough power to damage your eye's by stray reflections, even 5mW will cause damage.

I hate the fiddly little laser and am going to replace with a fixed line soon.

It does not have anything to do with the blade, It's under it, not behind it, shining along it from the end. It's not the way other blade laser are Wed, 22 May 2013 05:38:31 GMT John Herrmann http://groups.yahoo.com/group/4x6bandsaw/message/12327 http://groups.yahoo.com/group/4x6bandsaw/message/12327 Thanks, and congratulations on a *great* accessory! I'm going to have to add one to my Delta. - John Herrmann Wed, 22 May 2013 02:12:27 GMT Andy Wander http://groups.yahoo.com/group/4x6bandsaw/message/12326 http://groups.yahoo.com/group/4x6bandsaw/message/12326 I like the idea, but it seems like it can never be perfectly aligned with the blade. -If it is exactly behind the blade, and the same width as the blade, it Wed, 22 May 2013 00:02:03 GMT klondike1944 http://groups.yahoo.com/group/4x6bandsaw/message/12325 http://groups.yahoo.com/group/4x6bandsaw/message/12325 Yes, if you align the laser marker it will shoot the blade. I don't make a lot of production cuts so what I like is that I don't have a big investment in it, Tue, 21 May 2013 23:50:46 GMT Stan http://groups.yahoo.com/group/4x6bandsaw/message/12324 http://groups.yahoo.com/group/4x6bandsaw/message/12324 Thanks, Al! And thank you to all for the interest! 300 views in 24hours! I saw that HF laser when I Googled bandsaw laser guide.

Nice work on the laser install. FWIW I picked up a 'Laser Marker' at Harbor Freight. It has a magnetic mount, uses LR-44 or SR-44 batteries.

Like I said, I want it to be as narrow as the blade, ( which it seems Tue, 21 May 2013 22:12:25 GMT Malcolm Parker-Lisberg http://groups.yahoo.com/group/4x6bandsaw/message/12321 http://groups.yahoo.com/group/4x6bandsaw/message/12321 Paul Thanks for that, I have ordered two to try them.
