Regarding chainsaws inches are used as units. E.g. you can buy a 16 inch bar. In Germany this is sold as a 40 cm bar, but actually this is a 40.64 cm bar. Or chain pitch is given in inches, e.g. 3/8 inch, you won't go to a shop and say "give me a 9.53 mm chain". So we're in inch land regarding...

:) :) :) You could try it, but I would consider: Your theoretical average would be 7 degrees taking your measurements, but you already mentioned, that your real results were more similar to my Stihl 3/8 chain (what I would expect, I think that the results regarding the cutting angle should be...

Nice, so there is confirmation that the gauge works for pitches different from 3/8. :) So all common pitches (leave alone 1/4) seem to work with the gauge design. I assumed that, but wasn´t sure because of the lack of practical experience... Out of curiousity what´s the thickness of this...

The big critics only show up when they have the opinion and mood to find something to critisize. In this case with Mike presenting his awesome new tool there was nothing to critisize, so no need to show up ;) I know what you mean. It´s not so easy for me to 'address' people. I simply wrote this...

Yes. it´s satisfactory to plan tools, make them and use them. Ok, my gauge was more of a watchmaker´s work, your log rollers are more of a heavy duty style... But all of them are tools at the end.

What a shame ;) But thanks for following the thread :)

Nice "little" tools ;) Massive hooks! Their shape should allow to flip small and large diameters equally well. These log-rollers have a very professional impression to me. Ah yes, and in wood work you can bend everything... Like always it´s all about the compromise between stability and weight...

The really really good things in life take their time ;) I know what you mean. But like I said in the starting post, explaining things the short and easy way is not my strength ;) Maybe I presumed a little bit too much. I thought her I am at the biggest forum worldwide covering the given topic...

Hmmm ... for me the punched letters look hi-tech, I don´t own such 'tools' ;) I don´t use the raker depth gauge directly as well. I made one of my gauges out of hardened steel (1,0 mm thick) which leads to a larger cutting angle. It is possible to use this gauge directly without destroying it...

:) Yeah, it´s official, we have reached post #466 in this thread and you are officially the first person who has produced a raker depth gauge according to Hannes´Raker Depth Gauge™! ;) Seriously, nice job! Yes. I promised it and you seem to be the first person who really believed it ;) Sounds...

Thanks Pogo for the chart :) I used 36 RM 60 chain for my measurements. The number of drive links has no influence of course, and I think the gauge (0.050, 0,058, 0.063) shouldn´t either. The cutters´s shape full chisel vs. semi-chisel could have a small influence (if really), but it shouldn´t...

No. :) RS and RM are both available in 3/8 and in .325 pitch. RS is full chisel, RM semi-chisel chain, that´s the difference. Both are normal profile chains. Maybe you´re irritated by the naming 'micro'. That doesn´t refer to a smaller pitch or a lower cutter´s profile. The pitch is named by...

Are you really sure about that? I don´t own a RS chain to compare. Maybe someone owning both RS and RM should compare them and give a short comment about dimensions. Stihl offers its raker depth gauges in 1/4, .325, 3/8, 3/8 low profile and .404. They don´t make a difference between different...

Nice wording and I´m quite sure what you are meaning here ;) Oh. One person made this tool himself (beside me). Mission accomplished :cool: Still no metal piece in stock? The whole (modern) world consists of metal. Take an angle grinder and find some part, cutting out some part and grinding it...

Oh yes. My nerves got a little bit stressed sometimes, but looking at it with some distance it was quite an interesting process, at least for me ;) I think yes. One of my two self-measured presets refers to Stihl 3/8 RM chain. RM means Rapid Micro, it´s a chain with semi-chisel cutters; RS...

Yes, there were many people in this thread not liking my approach and they obviously didn´t move on ;) You can do it like that, but normally you don´t have to fiddle around with tangens or math when you want to know the angle. At least in Germany every pupil sitting the first time in a math...

Not so surprising I think ;) You obviously can trade in 'pivot length' for 'material thickness' and vice versa. Thicker material -> you have to go steeper for the same results. Thinner material -> you have to go less steep for the same results. So if you like to switch from .047" material to...

I try to make now some conclusions regarding the topic 'optimum cutting angle'. When using Carlton´s pictures and argumentations, it seems that optimum cutting angle = constant cutting angle. Like I assumed from the beginning of this thread ;) It´s only a matter of deciding the value of the...

Here I show the numbers for the .404 Stihl chain, ASSUMING a cutter´s angle of 11.8° (I don´t have the measurement). First, putting the Husky .404 gauge with soft setting onto it: The soft setting seems to be suitable as hard setup, it´s too weak as soft setup I think. Now the numbers for...

Maybe nothing´s wrong here, only a misunderstanding ;) Here a pic of Stihl 3/8 RM chain, positioned in rectangular manner for measurements on the computer monitor. The two red lines show the misunderstanding ;) What I call 'cutter height' in the context of my software and the raker depth...
