Topic: Laser line guide for freehand sharpening

[Antz]

So I have an idea to assist with freehand sharpening on tormek or paper wheels or bench grinders for that matter. First use a protractor to mark the angles you want to sharpen or shape at. Second mount a laser line market overhead. Then just shoot the laser on your choice of angle and sharpen away. Just keep the edge of your knife on that laser mark to produce consistent bevels. Just thought I’d share my idea. I haven’t done it yet but I will soon. The laser is pretty cheap (24$ US). And it’s adjustable. Here’s a link

Or this one

Sorry I meant laser line marker not market

Thanks. Sorry I didn’t know there was a thread going on this topic.

Antz, you are welcome.  They are so many threads and posts here. It is very difficult to get an overview of a subject. The search engine is often not very effective.

Jan makes a very important point. I have often been frustrated with our search engine. In my case, much of the problem may be operator inexperience. However, I wonder if we can do anything to improve things.  That is the reason I have started so many topics. I don’t know if this helps.

This would be an excellent opportunity for those of us with computer savvy to post.

I have copied the "Sharpco´s system".
I saw it in one of his videos about sharpening a Tanto blade.

I remember that Wootz use it too for sharpening convex blades.
I use this system for Convex and Tanto blades with good results. And the laser is very cheap (9€ in aAmazon)

I hope I have helped.

"Sharpco´s system" is really great. Directly sterile cleanliness of his workplace surprised me. 

The only thing I wonder about is the angle setting when he changes the SB wheel for the CBN wheel. Generally the wheel diameters are different. The same concerns the honing wheel. Maybe he did it off the record.

Actually I use Sb-250 and Diamond wheels DF-250 - DE-250.
Every time I change the wheel, I must calculate the new measure for the same grinding angle. Then, I adjust the laser to the new point and continue with grinding.

Just wanted to say I wasn’t trying to pass someone else’s idea off as my own. I really did think of it at home in my garage. But apparently I was far from the first person to think of it. I’m new to tormek’s. Great links and thanks for everyone’s input.

Thanks

Ideas come to many of us, I suspect that 99% of the home made gadgets in my workshop exist in other workshops, I may have a go at the laser I do like lasers

Antz,

CB posted an item in 2018 about a pivot jig based on 4 collars.  Rick Krug took that and came up with the pin pivot jig.  And then Gord Cameron came up with one based on a block of aluminium.  The progression of ideas allows for choices and preferences. 

So, please don’t stop.  These ideas are what is advancing the craft.

Kind regards,
Rich

I think the laser guide would also be a useful tool when you are doing kitchen knives as well. s you raise your hand to sharpen the curved part you should stay on the line to keep the  grind even. If you do not pay attention to this it is easy to have a wider grind as you approach the tip. While I doubt that it hurts anything it does not look as professional as a perfectly even grind along the entire edge.

I understand. My contribution is to provide details that can help develop your idea 
I hope your progress attentively.
