I recently opened a thread about this..... anyone of this DIY tool will mark center line , one or two line ...Center line on thin stock?
Specifically what is a good way to scribe a center line for a .100 kitchen blade ...
Never used this thin of stock before
A quick and dirty way would be to use as close to a 0.100 size drill bit. You can probably use an 1/8" bit and do both sides, then you'll have 2 lines that are only 0.050" apart...
