Baby C

[davidwyby]

Seems to work well, and leaving the gullet in square as well. For smoothness anyway. Might help with milling? I have some hexa to test, guess now I have more to test.

 

[huskihl]

So, get the gullet? Or don’t get the gullet? Those are the questions

+2 points for flair and style, though

‘Pears the gullet stabilizes

don’t follow him close but maybe getting it is for normal round file, “don’t ride too high”?

I could see the shelf pushing out chips

I thought this thread was going to be about something else before I clicked in here.

 

[davidwyby]

@maulhead that was an issue whilst googling

 

[Gullet]

You guys talking about me behind my back?

Trying to stay on topic Gullet in swedish translate to something like sweetie or cutie.

I made a face cut in one of my chunks here with a 20” on a stock 266. It cut. Shrug. More testing would be required to determine if much benefit. Could prolly have put more hook in it. Used 1/8” wheel on my USG. Could probably have put more hook in it. Was a beat up chain missing some chrome off the first part of the cutters. I got it got a little intentionally to harden a bit so maybe it would hold up missing some chrome. Used the grinder for the rakers for the first time…not sure about that yet.

No need to stray from what works best.

This top plate looks very flat? When you under cut it with a proper sized file it gets thinner and to the point of the cutter beak.

 

[davidwyby]

@Maintenance Chief yeah, it’s kind of a durable angle like Aussies run in hard stuff. I could tilt the grinder head over and make it racier. It’s was a fiddly operation and a bit hard to C, you see?

Could also be wheel profile.

 

[Timjus]

in round file stuff to mee baby c is just opposite you want. makes top plate angle blunt and just starts curving chips.
biggest round file you could fit and maintain hook would be more ideal for cutting/chip flow.

 

[davidwyby]

The edge and angles at those top few thousandths of the cutter are the most important, yes. At Kevin’s GTG I measured some chips. .008”-.029” thick. The diameter of file you achieve the angles with probably doesn’t really matter other than the 1/8” is a lot harder to see what you’re doing. I had better luck learning to square file on .404 than 3/8”. Possible upsides of leaving the gullet/shelf are like we’ve said, sweeping chips and stabilizing the cutter side to side.
I noticed some old C1 (Carlton/knockoff?) has a bit of a baby c and a differently shaped cutter profile that is more prone to keeping a gullet. Buckin does some sort of chip dump tunnel on his baby c. I haven’t paid too much attention.
Then the 59l .404…



I think a lot of it is splitting hairs and too many variables.

 

[davidwyby]

IIRC, Buckin had his baby C with the gullet in almost looking like square with the gullet in. The wood up there is soooooft.

 

[Maintenance Chief]

What about a goofy file, its practically made to do a baby c.

 

[huskihl]

Baby c might work better in conjunction with the shelf when you’re hawking osb-size chips out of a white pine or fir with a long bar. I can imagine it being different cutting the stuff you do, David

 

[davidwyby]

@Maintenance Chief maybe baby hexa

@huskihl yeah staying sharp is a lot more of a an issue than clearing chips, er dust.

You would think a flat secondary grind (shelf) would work better than a circular grind as a chip clearing feature?

Just hypothesizing. I grind everything. When it needs it, I back the tooth stop off and grind the gullet down to the straps, like you’re saying.
I’ve seen double raker safety chain haul ass with the front of the rakers filed flat to act as a plow to evacuate chips, as opposed to letting them slide by and falling out in their own time.
