I assume that the former is just a standard hard graphite lead, but what is "mylar-use stick"?Also, how thick will this ruler be?
Looking at the bottom scale, are the notches and graduations fully etched through the metal?
A Mylar use stick is a polymer "lead" that is used on a matte mylar sheets to draw on, used before CAD. Graphite Lead is used for tracing paper and regular paper.https://www.amazon.com/PEN3002H-Hi-Polymer-Lead-Extra-Black/dp/B000WH2XBK/ref=asc_df_B000WH2XBK/?tag=hyprod-20&linkCode=df0&hvadid=198068697245&hvpos=&hvnetw=g&hvrand=4623752592739377830&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9016806&hvtargid=pla-349454463810&psc=1As mentioned in the original post the thickness will be 0.25mm thick, so rather flexible too.The outer corners of the 9mm gauge are designed to the NMRA dimensions from outer flange to outer flange. Nothing more was asked, and I agree that I do not want to urn this into a multi-tool. I will use this added feature myself. I have never had the need to own an NMRA gauge as I have never hand laid track or had the need to inspect the track I buy.
@central.vermont Ask and all shall receive:
For me, a 12 real inch ruler is a little cumbersome to carry around.If I had my druthers about length, I would probably go for 6-3/4", because that is easy to keep in a shirt pocket and is 90 N scale feet long, which covers just about all of the N scale rolling stock that I look over in train shows, etc.But, not expecting to get my "druthers".
How do you get the poll to work? I can't figure it out! Bob
