Beginner's observation: watch your mark sizes

Postby prevariikation » 30 Nov 2022 16:17

Just impressioned my first locks, starting simple with a Master No. 5 & No. 7. An obvious thing I learned along the way: look for marks whose size is the right order of magnitude! I was chasing marks that were way too small or large for the size/bevel of the pin tips, and patiently waiting for a clear mark helped me calibrate the right mark sizes to pay attention to.

Also, re-read everyone's guides a billion times! :mrgreen:

And then you kept locking the padlock and using the key about 80 times as you thought "Wow! It actually works, and I did it!!!".

How far off am I? :mrgreen:

Congratulations, prevarikation! Well done.

Thanks! The Eagle and American padlocks I've been trying are quite humbling.

Watch your mark locations!

Another lesson learned: on a pin tumbler, marks on the side of the key could be wear from the blank scraping in the keyway, and it's a bad idea to chase them.

So happy to have succeeded on this odd American 350 that uses an M10 key.
