Customer Service & Support

We make every attempt to answer all email questions. However, we are still a small business so be patient if a response is not forthcoming within a few hours.  We build all units on an as ordered basis so please note the current production time shown on our Homepage before anticipating a shipping notice.

If you would like to discuss a particular application or design, you can email me at

We will also be glad to discuss technical questions or take phone orders between 9 am and 5 pm Central time  Monday thru Saturday at 817-832-7197.

If for some reason there is no answer, please leave a message as we return all calls.
