Tutorial: make your own raker depth gauge supported by software tool

[hannes69]

As for the depth gauge tool, I'd be happy to take some measurements when I have some time.

Thanks

Never could figure out how that would even work or what the slot is for.

I think, at least for certain chain types, it would maybe be possible, that at the total end of life point of the chain the gauge would sit onto the driving link directly in front of the raker, if this slot wouldn´t exist. Only an assumption, maybe it never would be possible, not sure about that.

I presume the measurements of interest for this exercise will be thickness of material and distance from saddle/straddle contact point (front notch) to rear of the raker slot?

... or using a .325 gauge on a 3/8 chain and so on.

Wouldn't that be the other way around? (3/8 gauge for end of life .325 chain)?

In my case, the hard and soft measurements are pretty much the same these days. LOL

LMAO good one.
Yep, used to be 9 with 1 wrinkle and now its 1 with 9 wrinkle.. Haha
Ok, I better watch it or Hannes will give me the boot out of R&D class.
He already thinks I may have been kicked out of English. Must be the sea of red that lights up on his computer every time he quotes me?

We (anyboby that's interested) are interested in trying to develop a dual gauge that only gauges approx .030 then another for .O25 so the shorter .325 gauge will work better for the last half of the tooth. or grind one until its perfect. Did you look through those charts?

Sounds good about the gauge measurements.
Do you file with it in the centre like that? What part of square peg in a square hole didn't I understand lol
I lock it in to the inside and back of square and put the bottom inside tap on the tie strap and file to the outside with the lean of the raker. I tried in the centre once and it was getting pushed around and have always used the side. I have kicked it off cockeyed to get them lower at times as well butted the outside raker into the female slot at the bottom centre.

3/8 chain has a longer run from cutter to raker
Plus with .325 the distance is shorter from lower base to top of raker slot. Shorter at the back means steeper but lower. The further the raker is away from the cutter the more sticking out from the top. .325 will take more material so would be better to use nearing the end.

This whole thread is hard to follow.

I would give a damn, if the whoile topic was really worthwhile.

No one has even attempted to explain why all of this is even worth it.

How is all of this somehow, better than the common depth gauge tools?

Apparently, each brand, model, variation of every chain would require a unique depth gauge tool. The variations over the last decade from Stihl alone is staggering. Which would make the number from all brands countless.

How? Or yet, why??

Simple questions.

Why not just use the available depth gauge tools, and go cut wood?

If one sharpened chains for a living, would you recommend making a tool for each chain that came into the shop?

If so, can you defend that stance?

Can the O.P. post 1 pic of one of his proposed gauges in place on a chain, in reality? Or is this all "theory"?

 

[HarleyT]

Respond to "1" of my questions,
please.

 

[HarleyT]

I joke around.
But I do make a point from time to time.

Show one pic of a chain that you have sharpened. Then a pic of one of your gauges on this chain.

 

[HarleyT]

Your gauge on a new chain doesn't count.

I only got halfway through the thread...figured I'd put this up and then finish later.

I enjoyed reading about your report Hannes. I spent a few months in Starnberg as an exchange student a long time ago. Being German is OK, but being a Bayer is higher!

Back when BobL's thread was running, I put this together:



It's clear acrylic glued to black acrylic on an offset to create a "shelf" for the clear acrylic. If you can see through the glare at the bottom. the angle that I want is inscribed on the black acrylic, along with a vertical line for reference.

Lining the point of the tooth up on the vertical line, with the other end sitting on the next tooth, you just look to see if the raker lines up with the angle that you want:



The tool is shading out the tooth in the above pic. I shot the next one at an upward angle, but that perspective makes the raker look way too high:



The upside of this is that it works on all my chains. The downside is that if you don't sharpen your teeth to the same length, the angle won't be quite right.

I meant the tool to be a rough draft, but I have used it ever since. I'm not really that fussy about raker angles, but it was a fun exercise.

Yes, I am a little "Rock'n'Roll"

 

[HarleyT]

Here.....

 

[HarleyT]

I know full well that there are groups of folks selling roses at the airport,
spreading the good news of perfect "depth gauge" apps. With the promise of better days, in all goodness in our global reality.....

 

[HarleyT]

I just have a "fuzzy" feeling that most folks just sharpen their chain, and go cut wood, and let the anal crowd blather on about spending a lot of time how to measure the depth gauges differently.
Winter is over for most of us,

whatever....

 

[HarleyT]

The vast majority of folks here cannot get the simple angles of their chisel even close, so getting all anal about the depth gauge tools is kind of silly. The depth is easily measured.

Well up untill now....

What do your good selves suggest for the raker file oil?

The part that I don't understand is why keep reading the thread and posting about how disinterested you are? No-one is suggesting that you need to care, but why not spend your time on something that you do care about instead of wasting your time, their time, and bandwidth?

If it isn't sperm whale oil then the raker will bind in soft wood.
