I have been trying my hand at grinding halfway or so up the blade, but it is super uneven and I end up just doing a full height flat grind, what do you guys recommend... what do you guys do?

Best thing I can recommend is practice, practice, and more practice...

Eventually you'll get a feel for what you're doing wrong and where things need improving.

If I had to guess though, I'd say you're rocking the blade slightly as you draw it across the belt. Make sure you're not grinding on just one side of the belt as you go acroos, and keep your angle relative to your platen the same along the length of each pass.
 
I am not being sarcastic but just keep grinding and it will come. I had the same things happen when I started.

A couple things that were pointed out to me were my stance infront of the grinder and the need to lock my elbows into my sides.

With elbows locked lay the blade gently on the belt then work back to the plunge keeping the blade flat on the platten and parallel to the ground.

To work the tip , drop the handle and rotate the wrist up.

I pay close attention to the spark patteren too ensuring that it is throwing across the width of the belt and not just on the edges.

Use layout dye and calipers to set lines to grind to moving up after to have ground to the line for the entire length.

I am just a NIT, Noob In Training, but those things helped me to straighten everything out
 
How are you starting your grinds? After scribing a .30 edge line/lines bring your blade to the belt at around a 45 degree angle. Grind to your scribed line. You will be making clean passes from the ricasso to the tip. Oops, before that... If using a file guide( I do) set the guide just forward on the blade from where you want the plung line. You can reset the guide later to "set" your plunge lines.. After the first pass, dipping the blade as needed bring the blade to the belt again and when the new flat gets to the belt tip the spine more vertical so there's a gap at the top of the blade(edge) Grind a pass on the blade keeping the gap even. It REALLY helps to have a good light overhead to create the shadow to see the gap. Using this method move the grind height up the blade towards the spine as far as you want it.

My mistake when I started was to try to grind the bevel angle I wanted all in one approach. Does this help? Am I suggesting something new to you?

Happy grinding!

One thing you can try is to grind off of the tool rest and use a push stick. Cut a notch in the push stick and rest the spine on the in the notch and the push stick on the rest. You can then pull the blade on top of the push stick while grinding and it will straighten out your grind and give you equal grind heights on both sides.

Oh and I recommend the bubble jig. It can really help train you to work your grinds.
 
The "Bubble Jig" is also a pretty good tool to learn to keep grinds even I don't use the bubble anymore but I still put the clamp on when doing finishing grinds, and practice practice and more practice,
 
Thanks for the tips. I have the same issue as the OP. Of course I've only ground two blades (neither of which are even done yet). I can tell already my stance isn't right and I need way more light (My garage is so dark I can only really grind during the day with the door open).
