Is it possible to bring the PDF up on the screen and scale it to the required size. Now do a screen capture. Depending on what you use for software you should get it in *.png or *.jpg format. Myself I use Irfanview for viewing photos or Screen Captures. Its free and works a treat.

Cheers  :beer:

Powder Keg:
I'm going to try and age the parts a little. The parts I made I'm not to worried about but the zinc plated stuff sticks out like a sore thumb. To clean the scale and the zinc off the parts I'm soaking them in vinegar and salt.

The vinegar will remove the plating. But keep an eye on it, rinse well with baking soda to neutralize the PH and dry with a soft cloth.If left to air dry it will and can rust.  The vinegar/salt mixture is an old time quick rust patina method. It will rust it quick, rinse well with baking soda to neutralize the PH then dry completely. Be warned that the rusting may continue after you are done even when clear coated.
Metal sculpture artists have that trouble, that it will continue to oxidize.
Looking good so far.
I have posted a number of photos in a thread on using vinegar to remove galvanized plating.

Powder Keg:
Thanks for the heads up Glen. In this case that's will be a good thing. The fellow I'm fixing this for wants the new parts to match the old ones.

Here they are this morning. Soaking in baking soda to neutralize the PH.



It took a couple days extra to get the plating off but they are now bare metal.

Stay tuned...
