So does he. That's why he bought a grinder.

True dat! It’s all I can do to lower the rakers

That's how I felt, you need one of these .

I thought I could square file pretty good, Mr Simington showed me otherwise.

Oh, I would kill for one of those...

Sure take a lot of chains to pay off one though.

Yep.
A lot of chains could be bought for the cost of one, if you can find one, but...

I would like to grind the full vertical side plate, however, with the 450 there is no vertical adjustment on the arm like the 451 has. I have to dress a thinner edge on the stone to keep from grinding into the tie straps. I did read in a maddsen's catalog that grinding 3/4 of the vertical is ideal. I just think that little shark tooth at the bottom has to cause some drag...

Good enough for who it's for

Shaun can make your arm adjustable. Depending on how bad you want it to be

Yea, I have that thread bookmarked... He is one heck of a machinist (and welder too)

No doubt. It's impressive

That is another process, you get the same results with other square grinders.
For cleaning the gullet I use a tecomec round grinder set to the same top plate angle(or a little more say 35-40 but watch the inside corner of the top plate) as what I'm grinding on the square, then add a little more side plate angle than I normally would use for a round chain, then I clean the gullet as low as I want, then all the way back to where the square grinder hits the side plate. As long as the side plate has enough square ground to cut as deep as the depth gauges are set it's good enough for me.

So, I took this chain for a little ride today in hard, dead oak. It is one hungry mfer! Is that a side effect of the forward lean on the side plate? I was wearing a smile ear to ear. Still good and sharp after a tank of fuel. I’ll have to see how it holds up with more use.
(angles don’t look too durable to me)

Looks real good sir.

Yes. The more lean the more aggressive it will be.

Thanks Mike! I was hoping you would chime in. It was eating the oak pretty aggressively. Should be fun in a softer log

Different chain. Pushed the arm a little too far, and went past the corner. Sharp but kind of fragile, especially in hardwood. It will gash the heck out of poplar or pine (or flesh). I always wear chaps. Always...

 

[RI Chevy]

Still looks uber sharp though.

Welp, at least you don’t ask for pics of the wood
