My mind is always thinking of a new way to improve a design on the frames.  My first attempt at a Tilt & Spin frame was driving me nuts!  I new I could do better and I finally figured it out.  A little Velcro and a change on the base, a couple new hinges and it was done.  You would think my brain could take a rest, but no - it didn't.  I started work on a frame that slides under your lap and on my second try - I got it. Perfect!!!  Well, I say it was my second try, but I would say I experimented with 20 to 30 variations on paper and scrap wood.  I built two.  I now have a base that I consider to be a little to tall. 
The latest endeavor is making my own hoops.  Wow, it's a lot of work, but I bet you can't buy one like it in any store.  Thick and heavy duty is the way I would describe them.  I want to play a little more with them before I offer them on the Website.  If anyone wants to test one, email me.  I will make you an offer you can't refuse. 
I am also considering making a low cost version of the frames.  What do you think? 
Well my kids are tugging at my legs, so I better get off the computer.
Have fun,
Harry
