Should an amateur attempt truing a wheel
If your question is, "Can an amateur successfully true a wheel on their first try?", the answer is "Yes".

A quick search on the internet reveals plenty of videos explaining the process.

Some things to consider:


Make sure you fully understand the process before you start
Don't use excessive force and take your time
Use a spoke wrench
Make small adjustments (1/8th of a turn)
You probably shouldn't attempt DIY repairs unless you can afford to replace anything you break, it's always possible you mess it up on your first try
