I just noticed something that you may be interested in putting together. In
the ShopNotes current magazine, Vol.19 Issue 109 there is a 4 page article
on building a cart that holds your shop vacuum, Oneida cyclone system, and
I recall you mentioning the possible need to make the container more stable.
this cart moves the shop vac and cyclone system as a unit and has on-board
storage for hoses and vac tools.
If you like I can scan and e-mail you a pdf of the article.
