It's not brand new, but I've only ridden on it for a few months. It's sat for approx. 6 months in it's out of true, spoke messed up state.

Iknow this was posted above but I cannot reiterate enough the value you will find here: https://sheldonbrown.com/wheelbuild.html
This is where I initially learned and I now build wheels from scratch regularly. Take it slow and learn from Sheldon. Read and come back here with questions. A tension meter can be helpful to check your work but as other have said there are many factors to balance out in the wheel assembly including the straightness of the rim itself. A rim with slight defects will not allow you to achieve balanced tension. Some state that tension is balance when all spokes are within 20% of each other. I shoot for 5% and usually end up between 5% and 10%. This assumes balance within all spokes on the same side in the case of a dished wheel like rear wheels or front disk wheels. I also use a cool spreadsheet/graph that Park Tools used to have on their web site. PM me if you want a copy. It can make visualising the forces in a wheel much easier for a beginner.

Seriously? The OP is living in Germany and just needs some help in learning to wrench his own bike. The school you posted is a great place to get an education but a little overkill for a guy needing a little info rather than trying to train to be a pro.

I would hope too that our young Cheeto has aspirations beyond twisting wrenches at a bicycle shop for a career.

Considering I've been accepted to Duqusne University's School of Nursing, I don't see myself becoming a pro bike builder, not meaning to offend anyone. I really appreciate all the help, and Sheldon's site is a wealth of knowledge. I know someone who has a truing stand and dish stick I might be able to borrow.
I am determined to get this wheel rideable again.

My point was to take a class on wheel truing or building. Like the classes at UBI or any where you choose. Germany has many similar opportunities. The classes are short term. You won't be a pro.

I dont speak German, and the classes are not availiable on base, great advice for someone in the states, but I cant.
I un tensioned everything, and going to follow Sheldons site.

getting equal tension works for new wheels for used wheels its a compromise of balancing tension and radial/lateral true. you have to find the balance of tension vs run out. even with new wheels there is a balance but not as big
