OK, some general tips on using an Oregon / Tecomec grinder, versus a HF type (copied and pasted, since this comes up so often).
I encourage you to get comfortable sharpening your round ground chains first, with the new grinder, before jumping in on the square ground, on top of that:
“ Keep in mind that grinders don’t sharpen the chains: you sharpen the chains.
For guys new to grinding (or a new grinder) I recommend taking an old or ‘scrap’ chain, and experimenting with it, before you work on your ‘good’ chains:
- ‘play’ with every adjustment on the grinder separately, and see what each does to the cutter profile;
- intentionally try to overheat, or ‘burn’ a cutter, then work backwards to see how to avoid that (lots of small taps, no sustained contact );
- place a sharp chain that you like in the grinder, with the power ‘Off’, and try to ‘copy’ those angles and settings with the grinder adjustment (and write those settings down);
- profile the rim of the grinding wheel, with the dressing brick, then lightly dress the wheel once per chain loop, to continuously expose fresh, sharp, abrasive;
- practice, and don’t worry about speed - that will come with experience.”
After you are comfortable with your new grinder, address the new jig and chain type.
