When I was about 10 years old my cousin and I set out to make a couple of slingshots.  We used the

forks from an oak tree, rubber from an inter-tube, and a pouch from the tongue of a shoe.  Then to put

parts together with a string we used conventional ways- they worked only fair.  I think that something in

the way of an idea laid dormant until I started to make the slingshot for my son Allan when he was

about 9 years old.  I wondered again how to attach the bands to the fork.  I thought of running the

bands inside the fork, then using a rubber lube I could shorten the bands, hense greater power.     

While deciding how to attach the bands, I hit on the idea of running the bands inside the fork.  It was

through this I discovered that the greatest factor for increasing velocity or propelling heavier projectiles

was to maximize the duration of applied force.  I used wheels and various configurations and when the

combination was right the results were startling.  I then applied for a patent. At this point the old adage,

"If you want something done right..." seemed appropriate.  We decided that rather than waste any more

time we would bring the benefits of my invention directly to the public.  We had several designs over

the next few years and Kent Shephard, the one with the world's largest slingshot collection had bought

some of each.  Slingthing tm, Pocket Sock It tm, Super Sling TM  As we didn't have the resources and

didn't have the sales and couldn't find a company to take over, it had to be put aside for the time being.

It wasn't from the lack of trying.  We contacted several companies with limited interest and several

other sports related companies also with limited interest.  I had several ideas for spear guns too and

contacted several companies and provided some models to test on an actual dive.  A  company report

stated that my 25 lb band was equal to his 50 lb band and my 50 lb  band was equal to his double 50 lb

bands but this company felt the smaller band concept would be a marketing problem.  Another

company gave me a model to put my modification on.  They decided against it and sent only the

modification back with a letter.  Some time later their engineer wrote to me and stated that I was right in

about 3 different ways and tried to interest the company.  Unfortunatley he was fired for this.

The third company was very interested but thought I couldn't get them enough patent protection. 

When we were develping Com Bow Sling TM I had one model for full length arrows that proved to be as

powerful as Slingthing with about 1/2 the pull.  One leading slingshot manufacturer was very interested.

I had a model for shooting full length arrows and they agreed that it beat the Compound Bow.  We took

this Com Bow Sling TM to a company and they were impressed as it could shoot a light aluminum arrow

as fast as 200 feet per second.  They actually paid me for 2 - 3 months to hold this Com Bow Sling idea

for them.  Legal problems on their main product line made it so they couldn't continue.   They were very

sorry and gave me a couple of their bows and a cronograph.  We tried some other companies to no

avail.  So we started a little corporation called Non Fire Arms Inc. and we went to an Ad Agency and

they had pictures, instructions, and press releases and sent them to several magazines and a few were

published.  We were off and running.....  We got quite a few orders and established some dealers and

after about a year Beeman looked me up and it led to a 2 year exclusive sales contract.  Things went

along pretty well for over 2 years except some of the dealers we had established before Beeman came

were not being honored.   It was about this time another company expressed interest and were going

to help me build Com Bow Slings.  This company was also working on some military applications and

recently found that did not work out.  This company decided to build a big cross bow called the Linear

Bow.   Some how the priorities changed and filling Com Bow Sling orders slipped and the Linear Bow

took presidence.  At this point the orders for Beeman were not being filled for a year or more. It took

awhile to get my rights back.  At this point Beeman was not interested in continuing.   We tried to get

started again but never did.   It was at this time the initial design and models for the Hotshot tm were

tested and develped.  We moved to Arizona in 1996 from California. I lost my wonderful wife of 44 years

in 2000.  I had to do something and I turned to my Com Bow Sling and had a one piece extrusion made.

I also worked on improving several things.  I also worked on some interesting new designs and made

some models with more extrusions.   I have always used extrusions because I have worked in an

extrusion plant and I knew how extrusions could be used in a design.  My son Allan has agreed to help

me and work with me and his wife Kathleen will help with marketing, webpage work and
