Only got a few minutes to look at it. Something's not right. Took the wheel out and still there's a slight wandering:

I can't feel any play in the motors shaft. But whith the wheel the wandering/oscillation is very noticeable. This was a freshly dressed wheel:


Is the collet that holds the wheel central machined properly?

I'll take it off and have a look and see what happens without it on.

Also wondering if the surging could have anything to do with the step down transformer (new, bought off ebay a few weeks ago) I'm using on this USA grinder?

Just hold something steady through the access cover (where you undo the allen bolt for the wheel) against the machined alloy part the wheel fits onto. That might show if it hasn't been machined central.

I'd say it has got a lot to do with it.

Collet was out a little but not much. Vibes less now that is kinda sorted via edge of grinding disk held lightly against it to deal to high spots. Thanks. Will have to find someone with a good transformer and see if that makes any difference.
Out of time tonight to see why uneven rakers.

It taken from a blog about saw injury's, here the writer claims what you see is all dinkum and has a story to tell of how it occurred and why saw chaps would have prevented it

As i teach basic saw use I research the how and why of saw injury's,, its how I found AS some 6-7 years ago

If you ever need to chase down where a web picture originated drag drop it into google images it will more often find the providence

back on the lube thing i have a rem 700 on it's 3rd barrel and never greased the lugs no probs here

it actually helps keep an even tension and wear on both lugs.
