I have been wanting to make one of these for a long time, but i could never figure out how to make the dome. Then I saw a post somewhere that a guy used a soda can bottom. I took a can and cut the bottom off and trimmed it with scissors then I made me a jig to fit the dome inside and pressed the top to flatten the edges. Then I turned the pot and fit the dome.... the hard part was configuring the inside to match the dome, to get that echo "bbbrrrrrrrrrr" but after a time I got it the way I wanted it to be. I turned the pot out of China Berry and had to cut a piece of slate to fit, (roughly) and used a glass soundboard....the trick was to leave enough room for the sound to travel into the dome and return back out without killing it or making it too overpowering. This is a freebie, headed to Savannah Georgia to Creekrocket, I don't plan on selling these without doing some research......I am going to make me one, but I will inlay the dome into the pot to where the edges are flushed with it....
Awsome pappy! I love my original thunderdome. I bet yours sounds even better. I know it looks a heck of a lot better.
i like that i have made them before but i put the dome on the inside for the tone board i found that smaller can like a v8 juice drink worked for me.i turned the dome over so it was closer to the strike surface.i was very surprised at how good it sounded. has a lot of rasp
Looks good Pappy.

I thought about moving the can bottom closer to the striking surface, but I lost some of the pitch when I did that and these cans seem to have been on the high pitch end of the spectrum. So I adjusted the pedestal in height and width to accommodate the can. I changed the inner walls from flat to con-vexed and worked that same on the floor, to have the sound waves to roll instead of angle shoot back. Really surprising how much difference it made in the volume and sound range. Of course there are always variables with the striker material used and the wood chosen for the pot, but that is yet to come....
That's pretty cool...neat idea!
That's awesome! I have an old crystal thunderdome, and it's always been my go-to call. First one out of the vest, and usually the last back in. I have several custom calls now, that I really love, but I still use that old dome on just about every hunt at some point. Glad somebody is trying bring them back, cuz Lohman doesn't seem to be interested.
I believe Lohman Manufacturing Company, Inc. still owns the patent on this design.

As far as i can find out they had a patent pending....never saw a patent number or date on a package...
"A patentee who makes or sells patented articles, or a person who does so for or under the patentee is required to mark the articles with the word "Patent" and the number of the patent. The penalty for failure to mark is that the patentee may not recover damages from an infringer unless the infringer was duly notified of the infringement and continued to infringe after the notice.
The marking of an article as patented when it is not in fact patented is against the law and subjects the offender to a penalty. Some persons mark articles sold with the terms "Patent Applied For" or "Patent Pending." These phrases have no legal effect, but only give information that an application for patent has been filed in the USPTO. The protection afforded by a patent does not start until the actual grant of the patent. False use of these phrases or their equivalent is prohibited."
I have done research and have seen no such patent date or number on any of the packages so far. But thanks for the heads up .....CW.....
A quick google search got me this for you Jack.
Patent #5562521, for a turkey call.
Inventor: Butler, et al.
Date Issued: October 8, 1996
Application: 08/575,126
Filed: December 19, 1995
Inventors: Bishop; Ricky J. (Warm Springs, GA)
Butler; Terry L. (Neosho, MO)
Assignee: Lohman Manufacturing Company, Inc. (Neosho, MO)
As you can see it is patented, from a quick scan of the abstract it is the idea of using a convex metal shape in the call that is covered. Just because the packaging of the Item, or the Item itself that your are copying doesn't say a patent # doesn't mean they don't have one.
CW
wow that was good info. Thanks, that just answered my question didn't it. how in the world did you find that? I looked all over, shows you how much i know about computers...lol, thanks again.
Then name your call bottoms up. Then its a concave metal shape :TooFunny:
Need to honor the patents, if not we have no reason to gripe when the big guys steel from us.

Good thing the younger generation watches out for you! Patent Attorneys aren't bad when they are on your side.... but I wouldn't want to sit on the other side of the table.
CW
I hear ya, again, thanks for keeping me in the clear on these things, I think there is hope for this younger generation....lol...lol....
another good question is how long does that patent last being that it was issued Oct 8, 1996
"For applications filed on or after June 8, 1995, utility and plant patents are granted for a term which begins with the date of the grant and usually ends 20 years from the date you first applied for the patent subject to the payment of appropriate maintenance fees. Design patents last 14 years from the date you are granted the patent. Note: Patents in force on June 8 and patents issued thereafter on applications filed prior to June 8, 1995 automatically have a term that is the greater of the twenty year term discussed above or seventeen years from the patent grant. "
--------------------------------------------------------------------------------
That is a good question, I would say it has at least the latter, which looks to be the 20 years. And rightly should be so, so as to protect them from being copied to exact measurements....I can understand the need for this, but as little guys, I always wondered what it cost for a patent?

Well that was a fun read. Now I am no patent attorney but after reading this I wonder how solid it is.
In the patent they discuss a molded in metal dome structure, molded in a plastic pot using a slate surface. And they go so far to say to be used with a carbon shaft striker.
The call is detailed in a way that it protects this variation and build but i wonder how enforceable the patent is to different call configurations? Always best to contact the patent holder I guess and ask for permission.
I included the downloadable patent for those wondering, or needing some reading that makes you :z-dizzy:
Thanks Van......went over the patent in the abstract it refers to the "dome"....
(A generally dome-shaped structure is positioned "within the housing" in spaced relationship from the planar slate member.)
Since mine is mounted on the outside of the pot I am wondering if that is the same thing? I have tried to contact T. Butler, no luck, another site shows that the patent has expired, which was applied for in 1995 and awarded in 1996. This stuff gets hairy, my head hurts just from reading it. Gonna send this pot to Mr. Butler if I can find his address and see what he has to say.
Where are patent attorney that has a callmaking hobby ;D
As I understand the real patents is in the details, the more detailed the patent the narrower the protection but the easier it is to be successful in the granting of the patent. But thats just my understanding :morning:
" Damn Boy's were in tight spot" from my favorite movie O'Brother where art thou..
Hey Pappy
Can I have that Thunderdome cause when you get to THE BIG HOUSE all you gonna make is license plates ! :funnyturkey: :TooFunny:
I bet his license plates would be some of the prettiest and best made in the entire country!
Just got off the phone with Ricky Bishop and he has no qualms with me pursuing this, so I will make a couple in different materials, crystal is next.....thank you all for your help and joyful words, I won't be worrying about making calls out of license plates.....
