Thanks Doc,
Much appreciated
Much appreciated
Much the same thought I had except I was thinking of just locking up my shop and throwing away the key.Honestly, I don't like this pen.
Don't get me wrong. It's beautiful and amazing, but it's mere existence makes me want to sell my lathe.
Many thanks Alexone of the most beautiful pens I've seen in the forum, totally outstanding
Lol Steve, no dont do it! I like the pens you turnHonestly, I don't like this pen.

hm been called thatonce or twice before lol. Thanks Jonathon. Hows the little one by the way?Not much to say that hasn't been said. Mad scientist for sure though!
The pen and process is amazing Brad! Can't wait to see what else you come up with.
Many thanks :redface:Beautifull pen doesn't really say enough. One of the best!
Thanks Jim, so was i when i realised it worked :biggrin:Thank you for showing the process. To say I'm amazed is an understatement.
I always thought potions would smell nice lol. mind you they dont smell half as bad as what that resin does.... lol we have quite a large footprint to our home and can smell it from end to end. Think i may use the fume hood next time.Just incredible!!! It's like watching a mad scientist / magician conjure up a beautiful sculpture from all his weird and wonderful potions!! :glasses-nerdy::biggrin:
Thats a mighty big wow :biggrin:I can only say, WOW!

Thanks John, its appreciatedWell done Brad! luv your pen and work.:wink:
Brad: I don't know what I can say that hasn't already been said. I know no words worthy of this creation. It is deservant of every compliment received.
Beautiful Brad, and nice detail with the centerband, as if it didn't already have detail

Well, this has been the most challenging pen i have ever turned, and the one i am proudest of.
The second issue is smut. as the metal is corroded is leaves a layer of filth behind, and if this settles on the metal it protects it from the etchant. as a result of this it stopped etching down, and started etching outwards, eating away at the lines i was trying to preverse. this is known as under cutting, and can be avoided with ansiotropic etching with gases, but thats beyond the scope of this post.

Just so. It's looks amazing.

I used to see this when I started etching printed circuit boards. Clearly, they are somewhat thinner, but my solution was to stick a fishtank bubbler in the etch tank. This stirs up the etchant, preventing the sludge from settling. Would that be any use?
Yes you are on the right path. my vertical etching tanks are equipped with bubble lines, though for this experiment i wanted to try and get away with just using citric acid (which works fine luckily) as if the stream of bubbles is too strong it can effect your vinyl mask, whereas with PCB you generally use photoresist exposed to UV and devloped which is much tougher, albeit for shorter durations in the tanks. I doubt it would stand up to an exothermic reaction.
You could experiment with air, though make sure its turned down low. i found the citric lifted it nicely and half way through the cycle i gave it a gentle wipe with a toothbrush.
lol i wouldnt use the term "squirt" it was measured by ratio, dissolved in boiling water and blended into the ferric chloride.
