Blast from the past.

Very Interesting....35 top-plate....would like to run that and see how it worked....of course some say the old saws had more torque that the higher RPM saws of today...

Here is a .325 Stihl RM chain I ground with the CBN wheel....


Here is some silver maple chips from my 026 with a .325 Oregon full chisel chain.....I forgot to take a picture of the chain.......I ground it at Oregons specs.....25-55-10.....it's amazing how much easier these softer woods cut when I am used to cutting hardwoods....

Wow .060 on rakers that would hell on a chain and a saw!

Yes that's twice as much as .404 chain. What the heck. .030 makes my 77cc burn some serious fuel . Must be for that twin cylinder chainsaw that was posted while back lol. [emoji3][emoji106]

The Stihl.404 chains I sharpen to specs I have set the rakers at .032 every time I sharpen them
There powered by a 10 horsepower electric motor

Silver Maple that is not seasoned in a very low humidity environment is much different than very dry aged Oak. The setup needed to take advantage of the best chain possible is much different. I have discovered with soft wood that an aggressive angle with some low rakers will melt through the logs. The rakers are not so crucial for soft woods, but with hard woods the rakers are very crucial in that they need to be just right. The cutters will get dull in just a couple of cuts if the rakers or too high, but will chatter like crazy if they are too too low. However with large Oak logs an aggressive raker depth with a more shallow angle and the leading edge a little blunt works well as far as staying sharp the longest. Chisel chain has not proven to be of any value in California, but in other states they seem to be the E ticket. For me semi chisel has proven to be the best here. Thanks

If you know what you will be cutting, it's possible to optimize the chain for the wood, your saw, etc.

If you don't know what you will be cutting it helps to use the general angles. These are the angles that manufacturers recommend, and that come from the factories.

Another option is to have different chains optimized for different types of wood, or current conditions, and swap them out as needed. Kind of like a socket set.

Good idea!

I do not buy semi chisel chain unless chisel isn't available for that size but always end up with some of it in each common DL length. I keep it around just in case I need to cut some gritty stuff.

I need to clean the garage so this weekend I am going to individually bag and label all of my chains so I never need to stop and count DL's again.

5mm Dinasaw arrived today. Actual measurement is 5.25 mm or 13/64". Too much going on now through the weekend so trying it will have to wait.

First sharpenings with new wheel. Outside to inside; 30* 60* no tilt. Ron

Looks like a coarse cutting wheel, but hard to tell from the photos. How does it compare to grinds made with other wheels?

Is there a grit size listed (e.g. 60 grit, 80 grit, etc..)?

Thanks.

Philbert

The only other wheel I have is a 4mm Dinasaw. Grinder came with a pink wheel but it broke when it hit the floor - never got to use it. Pictures from previous post showing results of 4mm wheel on 3/8ths. Ron



Post 350:

From Bailey's website:

Q. What grit size are these wheels?
A. Dinasaw uses a blend of Borazon to achieve the best results. The grit comparison would roughly be between 60 and 80 grit on the ABN Cyclone Grinding wheels.

What brand of grinder do you have....

Only reason I ask is because I have a Oregon 520...with my grinderbthe 60 top plate face angle is way to blunt....on mine 50-55 degree head tilt puts the perfect hook on my chains.

Looks like you won't be burning cuttiers with that whee..... does it cut fast, looks like it does...

.404 205 drive link

Hanging off the floor at 6'10 3/4" and almost touching

Taking a big cut with the diamond wheel and it's rolling the chrome a little but it had a 164 cuts on the chain mounted to a Holtec saw that cuts bundles of lumber
So there is 284 2x4 ina bundle
so 46,500 or or so of 2x4's on this chain https://uploads.tapatalk-cdn.com/20170421/d0747be0d2df45806232d0cbcd3aea03.jpg[/IMG
This is the amount of chain that is under the the grinder knotty up with the rail guides 50 1/2" off the floor
It's a workout for 25$ and still knock the rackers down to .32

For the pic that didn't load of the knot of chain under the grinder

Looks like you need some kind of 'bogey wheel' to keep things off the floor. Maybe one that is removable when not needed?

I tried a little and give up
But it's still on my mind

Thanks for the inspiration !
Had serval beers any jury rig a plastic roller so it wouldn't dull the teeth and haven't fine tuned it yet but wanted to thank you for the drawing and I will post the prototype
You are a hella guy to have around to help unworthy electricians sharpen chains. LOL

Will tell you that there will be some copper involved and soldering and that # 6 solid will still let me turn the table to 30 degrees but no further
