Disston Keystone K 140

[Treeline]

Here's a Disston Keystone K 140 Perforated Lance tooth bucking saw. It's 5' long. I don't believe this has ever been sharpened or used. I plan to clean it, sharpen it, and use it. I'll post up more photos once I've tried it out.

Good looking saw, and good length. I also like how the rakers are shaped on the inside.

Nice saw Treeline.Do you remove alot of the metal on the inside of the rakers shaped like that to get them to swage?I am filing a holow back felling saw perforated lance with rakers shaped like those.I tried to swage them as is.they wouldnt budge.I ended up filing a v with a slim tapered file.Still they wouldnt swage so I started filing the inside into a v before I could get them to swage.Do they swage well for you as is?Brother Benjamin.

I haven't needed to do anything differently with this shape raker. They seem to swage pretty well. On really hard steel, I sometimes will use a mandrel and a heavier hammer to swage. This method a requires fewer strokes of the hammer, and there's less likelyhood of a misplaced stroke.

Treeline,
Could you say or show exactly what kind of mandrel you use for swedging. Sounds like it would be a good idea to put some weight behind a tooth being swedged but it would be nice to see what you use.

Hi Jim,
It's basically just a solid, tapered piece of hardened round stock about 5" long with flat faces on both ends. The "hammer" end is about 1" and the "swaging" end about 1/2". The extra heft and being able to hold it stationary and at the proper angle makes swaging ( for me ) a lot easier, especially on really stubborn rakers. I'll try to get some pics and post in the filing section.

Thanks Treeline, that makes sense.
