As a upcoming mechanic. Tools are needed. In most Asian vehicles 10mm bolts are pretty common. So it's either get a extension with a 1/4 rachet or make something.
This is what I made. 99% of tuners would know what it is and have it but I'm sure there are few who would be glad for this advice.
Piece of advice though. Next time, try and find the centre of gravity of the handle piece (top of the T) and then weld in that region. So when you using it, it would have a better weight distribution and be more balanced!
id agree that masking tape isn't the best use for the application he wanted but corrosion protection tape is an engineered solution for corrosion resistance
