Atop sharpener

Here's another one.

Pretty cool... Dude! But 6-10hrs!! Phew!! That takes some patience! Soo.. As far as the rakers on this chain go, do you shape the outside of them too? I did that on one chain but in a way that there was no consistency in how much was filed off from link to link. I took it into work the next day & the thing sucked! It would buck great, but trying to block down or take a large pick with the crane it kept jamming up as if I was getting it pinched even though it wasn't. Needless to say I haven't tried that sharpening technique again. What do you think happened?? Too much random bite?

Yep a lot of time with files and stuff in them. It's worth it if you like to race. I just barely touch the outside of them. It may not have been clearing the chips good.

 

[jimmycrackcorn]

I suspect that was the case..
Say.. Have you been on the Stihl site lately? I was just there & seen this http://www.stihlusa.com/products/chain-saws/professional-saws/ms440r/

Is that correct? I've been out of the loop for a bit, ever since this joint got kidnapped by hackers..

If the guide really works, I may have to pursue it. Square would be a God-send on soft wood take-downs...

It works pretty good. I never got to try it. Baileys sent out a demo to a few people and they were supposed to pass it around but it got lost or something and didn't finish going around.

I have a Atop guide and Valorbe files. It all works as advertised. I made a couple chains with it and then got a Silvey square grinder. I prefer the grinder

Ahhhhh those guys!! I googled imaged "Oregon file guide" before I posted that post to see if there was a guide from them I did not know about, thinking back to last night I think I recall seeing a setup that looked unconventional, like maybe it was holding one of those square bevel files. It might of been a thread, you should google that phrase above & scroll through the Images, maybe you'll come across it.





I've never really liked those types of rigs, either I'm too dumb, don't have the patience, or have had a real crappy quality one. I always end up tossing them aside and doing it by hand. However, If those rigs are capable of doing square ground, I wonder how that 6 sided chisel bit file would work with them? It's less bulky & would leave more room to manipulate... Just thinking out loud here but, I doubt one would want to try and convert round to square using the jig, as the strokes can get pretty jumpy & need a lot of pressure.

I'm surprised no-one else has joined in the convo here & spoke about the ATOP, I always hear everyone ranting and raving about square ground. I figure there's gotta be more than a few ppl out there with the it seeing as how hard filing square can be to get right. Plus.. ATOP's marketing video is awesome...haaaa!

Looking back over the summer, I really spent ALOT of time, effort & $$ trying to learn the technique after work hours. I think I'm just gunna buy one once the extra funds start rolling back in come spring.

Hey W8ye, do you know if there is a sticky thread specific to race chain? All I ever find are dead end threads when looking. They seem to be scattered everywhere too.

About 30 years ago, I had a Granberg filing jig made for double-bevel chisel files. As I recall, it had plenty of adjustment to set it up just how you want it. Seemed to do the job, but it was a slow way to do it and maybe just a little sloppy. I gave it away to another timber faller whom I was teaching to chisel file. Might be worth it to some people to try to find one.

And mdavlee's chain above looks way fast!

Nice clean gullets Mdavlee

For the record, I sold my Atop jig to one of the posters of this thread.

How do you think the atop set up works I was considering buying one?

They work great for a chain that's already square.
It takes a whole file to make a round chain square.
