Well they key to scribing is to understand it's 110% technique

it's something you have to practice. And it's just one of those things

where you have to get your hands to do what your brain wants. The

more you do it the more memory you get for it and your set, it's like

riding a bike.

Looking good G nice scribing you will only get better!

i noticed in the last pic the two horizontal lines coming

off the vertical don't look 90deg for their full run. That

means the distance is off on them from top to bottom.

I used to do this a lot also i learned to check the distances

from using reference points.

For example measure the distance from each end

of the lower horizontal line to the bottom of the

stabilizer, when they are equal then make your

pencil line and scribe. When you get the culmination

of straight and clean mixed with equal distances that's

when they really shine. Like you said you have to do it

slow because there really is a lot to concentrate on!

Your doing well and your learning that's really what

it's about! ;D
