Let's See Them Chips !!!!

[DucTruckin379]

So a few years ago I got the lady this little pruning saw (she loves it). I checked it out, just to see how dangerous it might be, but never really cut much with it. Pulled it out today and gave it a few passes with the file, and went to town with it. It's actually pretty impressive...

edit: This is where the battery died and I had to go get a real saw...

Makita EA4300F, full chisel Dolmar 686 .325" chain, ground on my MAXX and additionally touched up and rakers set with an Archer FastFiler roller guide.
Dry ash.



P.S.:
The cutter discoloring is from the saws previous owner!

And yeah I pinched her bad. Cleaning up storm damage. Stuff is twisted up in knots

12.9 grade bolt steel chips from drilling, dang that is some serious steel - I love it!

Top: 12.9 bolt grade steel (above grade 8 US)
Bottom: "normal" carbon steel

Same drill bit (5.0mm Solid-Carbide), same feed, same rpm



Metric/ISO compared to US/SAE, thanks to Steve @166

That looks like it's just a matter of time till you break a drill bit.

They have good bits over there.

11.5mm Solid-Carbide drill bit doesn't care, even had some sparks flying!
Usually I would implement liquid cooling processing any steel, but I was prototyping and adjusting on the go and didn't feel like messing with liquid cooling.

Nah, it's not that.
It is because over here we utilize the metric system so everything is easier, even processing 12.9 grade steel!

LOL

You silly base 10 people have probably forgot how to deal with fractions.

I know that my di©k is always 1/2 the size than what she craves, at best.
Also, I know it'll hurt my wallet when my cars fuel gauge shows less than 1/4 full.
I don't want to have more fraction knowledge than that!

At least we 10 base people can state precision tolerances in a language most every modern machine complies to , +/-0.001 - air is thicker than that.

Well, the fuel thing is actually a lie!
My cars fuel gauge is shown in bars.

You can easily drill and tap 12.9 bolts with hss tooling by hand.

True!
Just a matter of correct rpm & feed.

But my way is more fun!

Regular "soft" carbon steel, drilling with chip breakage every 1.5mm.
The second picture shows a noodle from drilling a 11.5mm pilot hole.
The third picture shows noodles from widening the hole to 16.0mm.
No liquid cooling.

I still need more practice but my chains are getting better.

 

[Guido Salvage]

The pile keeps growing… it is now over the fenders of my mill, time to clean up!

 

[Wolverine]

Been making some dust myself lately. And noodles.

How are the chains holding up? Looks like a workout!

Measured one of my loads on a local CAT scale. Wood and 2 saws were 2,200lbs.

I still don’t have a dedicated wheel profiled for milling angles, so there’s that. But they held up great in this honey locust. Very hard dense wood. After 4-6 cuts, I’d swap out chains so I can easily and quickly touch up. I have no doubt after those cuts, I could have bucked and produced large chips. Pics are in milling section.
