I'm sure everyone has run into this problem when they first started grinding.

With designs that dont have a plunge its not a problem, but sometimes this happens where I begin my grind, on the other side of the belt from the plunge, then I have to spend lots of time getting it all evened out

Anyone got any tips for how to avoid this?
 
Over time, you'll learn how to maneuver the blade so that you imperceptibly lift the blade on the side of the belt away from the plunge as you work into the plunge. This requires a concurrent lessening of pressure as you work into the plunge using more the side of the belt nearest the plunge to do the grinding and care not to inadvertently raise your bevel line higher at the plunge. Practice, practice, practice.

Until then, a few tips would be to never pause as you work into the plunge, always go right in and right out. Also, watch where your sparks are flying and make sure to keep them coming from the center of the belt as you approach the plunge (this also helps with the tendency to have a higher grind line at the bevel than in the middle of the blade). Also, don't try and start your grinding pass right at the plunge and work to the tip. Rather, touch the bevel to the belt a bit away from the plunge, move into the plunge area while using gentle pressure to find your flat, and then work towards the tip.

Thanks for Your insight!!! very well depicted....when reading i feel like i am in front of Your grinder!
 
I seem to get the best results by starting the grind somewhere near the middle of the blade, and keeping it moving. I sort of swipe it onto the belt.
Thanks for the advice.
 
Harvey Dean's DVD on flat grinding explains this and he shows how he lifts the blade slightly off the belt except on the plunge side to avoid the "dreaded 2 inch disease" :P
