simington 451 adjust

[climbit]

I've been searching for some info on the adjustments that are on the simington 451. I can't seem to find much and was thinking you guys could help me out.

I'm wondering about the vertical adj. on the arm. What affect will it have on the tooth? Then the adj. in and out (the horizontal plane, if you will), not the tooth advance but the arm itself. Exactly where will this affect the tooth.

I've been grinding on a swing arm that is setup, this is the first grinder I've messed with. I've messed with them but I guess I'm missing exactly what they are changing on the tooth.

Also do you guys run the chain guide vertical or tilted forward. I've seen both.


Any info would be great

EDIT: I probably put this in the wrong spot. I put it on the chainsaw thread too.

Jake: I,m suprised no one replied .. The verticle adjustment on the swing arm raises or lowers the tooth on the wheel . .... With the 450 Simington there was alot of work with changing the dressers and getting the height of the wheel or putting shims in between the base and the arm . ..................... With being able to slide the chain holder fore and aft and up and down .
.
. I run mine canted forward about 2:30 ... . . .At least when grinding the right side cutters ...

Oh I forgot . . . You need to figure out your own grind and joint for the timber your in , your saw , how u like it to cut ect.

Wheel

Well I got it pretty close. But I need to lower the wheel (actually the arbor) on the motor shaft. I took the "lock bolts" (for lack of a better term) out but it seems to be stuck on the shaft. I cant budge it. Is there a puller of some sort. Anyone know if a 3 jaw will work? Suggestions Please.

Also if you use the in and out adjustment were will you see the change on the tooth.

I'm trying to match a chain of another grinder that I like but I'm having trouble getting the diagonal angle of the tooth to match. By that I mean the angle that is etched for reference on some chains

Also I'm seeing a little variation in tooth length between right and left. I can't figure this one out at all. The only way I could see that is if the arm was bent. It looks like cast to me so it shouldn't bend???

Are the drivers snug in the guide? If the chain rocks side to side it will make variations.
You should be able to move the chain guide easier than the arbor.
The chain stops are what you adjust the tooth length with. There should be a left and right stop.

If you have a 451 Simington it will have the fully adjustable arm . it will move the chain holder up or down . can you post an up close pic of your grinder arm / .. With the 450 Simington the arbor had to be moved up or down a little to get things set just right . with the 451 just moving the arm up or down did that .

451

Yeah i have the adjustable arm. But I'm maxed out on adjustment. I have moved the arm all the way up to get my desired grind. I would like to go up a little more, but am out of adjustment.

The arbor should be moveable like the 450's correct? I would like to drop the wheel a little to be able to move the arm back to center, as it would allow a little room to play with things. Its not a big deal. I have the thing pretty close now. Although my grind isn't great in the harder doug fir.

Found a guy in loggers world that sells refurb. 451's and parts might try to get some new tooth stops and a chain guide.

thanks, for the info

If the drivers are loose in the guide, check and make sure the groove is the right gauge.
