Any tips for making serrations?

[PEU]

I laser cut the profile and then use round diamond file to give it the tooth edges.

Nice big blade!
I am no longer laser cutting blades but maybe having the outline of the serrations cut before ht is a good idea.
I'll be making my next serrated blade this week - a damascus one this time so I better make it right.

Seems like there are a lot of ways to do it. In the past week I learned how to do it with my dremel. Ground the blade nice and thin post HT, and then cut them in with the dremel, mindful not to make contact too long or with too much pressure, so as not to overheat the steel. Then touched up with ceramic rods, stropped and good to go. To install serrations on an existing plainedge this way will now only take me a few minutes.

This first pic is WIP, but I since made sure all the points were actually points, and that the blade could do this:

This was one of the first things I tried but it didn´t work at all. Maybe it was the cutting tool I was using on it. Wich tool have you used?

First these to shape:

Then these:



Burr removal and final honing with ceramic rods and slack belt strop with green compound, both sides.

MagnaCut after dremel and strop on cardboard (the ceramic rods and strop are at home). This is my fifth time doing serrations, my first time being a week ago. It took maybe twenty five minutes.

If I can do this, you're going to pick it up easily I think.

I feel like I spent more time putting this post together and struggling with fixing all the typos than I did making the serrations!

 

[David Mary]

Serrations, sixth time, on another knife that I already made but decided to convert. I didn't it since my last post.

 

[David Mary]

Both knives were already very thin behind the edge to start with and I brought the opposite side bevel to zero before making the serrations. After I hone these at home they are going to be arm hair shaving sharp.

Pretty much I need an intervention.




Somebody st(r!)op me

I have a couple of bread knives in planning, was fixing to use the small wheel and adjustable work rest.

Am now wondering about a jig with the same diameter rod as small wheel as a reference point. Would have to do first 2 by eye carefully then rest could be done with the jig
