A little more on the advice thing;
As many of you may know I am a bowmaker more than a gun builder, been at it for 27 years, it was a 27 year learning process but I pretty much have it down now.
I teach bow making online and in my shop (never charged anyone a penny), people today are making the best bows that I have seen since I started, true works of art. Twenty years ago people didn't have the available reference material we have now and made some monstrosities then posted them online for an attaboy.
I would give their bows an honest critique, gently of course, and offer suggestions on what they could do to salvage what they had hacked out.
People jumped on me in droves for my honesty, nasty name calling and treating me like I was a wart on the butt of bowmaking. Fortunately the other good bowmakers recognized that I knew my stuff.
One day I had enough of the abuse and made a post to the effect of "what do you want", sound bow making advice to advance your craft or guys telling you how great your bow is even if it is a disaster. I told them if it is the latter I wouldn't say another word.
The overwhelming response was "sound advice", the guys who were sending me scathing PMs and jumping on me quit. I have helped hundreds fledgling bowmakers since, I spend 3 or 4 hours a day doing just that.
