Thanks for the responses...all good

I like the idea of the junk yard...though lately, those guys think everything is gold

...that's a whole 'nother rant...I did make a couple of horns using the plans I got off ebay. Go to youtube and type in "pvc train horns". The guys name on there is dozerboymiller. I made a couple, and they really are loud...even with just blowing by mouth. I will have to post a video up of mine soon.
Thanks again,
James
