Simington / Silvey Square Chain Grinders Tips/Tricks/Secrets

[chipper1]

I ended up milling the box off, boring the hole out and mounting a motor like the new simingtons have on it.

Thanks for the response as well as the pictures, that looks great.
I may just rob the arm if it's the same for the 450.

Pictures (and distance taken) make things look small or large many times.

They do.
This one is waaaaay smaller than the one on my 450, it's apparent why they call it the beer can motor.

I finally got to spend some time playing with the grinder.

Found a used 451C.
Now to learn how to use it.
Will make a trip to Madsens soon to get some grinding wheels.

Congrats, the wheel on there now is a soft one. I have a preference for the blue to touch up after use, or white for bringing back to a good edge from abusive use. With a little reading here, and practice you may wonder how you got by without it.

Congratulations !!!
From what I can see, you’re going to have to take alot off that wheel to true it up. That might be why your seller was selling it ..?

I’d just run a new wheel after getting the dresser angles close

Salmon wheel is a good compromise of aggressive and lasting. The gray waxed is the best to take a big bite off a tooth without burning it if you don’t make a coolant setup.

This is straight off a salmon wheel it’s all I’ve ran the last 10 years, my old man loved the white wheels as well as the gray wax wheels.

Did you clean out the gullet after grinding or did it come straight off the grinder like that? Looks good to me.

I enlarge the wheel thickness depending on the application say I’m running a 32 on the 390 or 36 on the 395 so there’s no gullet. Now if I’m running a 32 on the 562 I’ll thin the wheel out a bit so there’s a gullet there’s many ways to skin the same cat. I’m not sure if you can do this exactly on a simington grinder or not without taking a good amount of the drive strap.

From what little I’ve seen so far I would think the thicker wheel would get into the strap for sure. Other who know what they are doing might prove me wrong.

Depends on how sharp you want your angles vs how long you want it to last.
With your wheel, without hitting tie straps, it would be tough getting a tank through the saw without sharpening in our hardwood. My wheel edge is thinner

On the pro sharp I can change the inner without dropping the top below the corner, if you drop that outer corner you can make it “sharper” but you lose out on the strength of the corner.

I've had an RS2 close to 30 years. Bet I've not even sharpened 1/2 dozen chains on it. Never could get them ground to my satisfaction compared to square filing. (Except one time which I remember well-can picture exactly what trees on what woodlot-perfect) Reading this thread got me to dust it off and give it another try.
@Deets066 I was going to ask for a closeup of your wheel, but found one a few pages back that I will reference thanks. Ground one last night, came out looking like a bit of a race chain.
I've got a much better understanding of square ground now, between filing for so long and reading here maybe I can be more consistent with the RS2.
