Caster Wheel Upgrade on Garden Towers

"About once per week a suggestion or request for wheeled Garden Towers is heard from a customer or fan; the Garden Tower Project does not offer the option because Garden Towers are large and heavy animals and in the wrong location a free-wheeling tower could be quite dangerous."


The following instructions can, at your own risk, be used to effectively make the Garden Tower more mobile. Customers also use large planter dollies and drum dollies for the same purpose.  None of these approaches should be used on soft, rough, or inclined surfaces.

 

Project Notes:

- Try to find casters made out of nylon plastic as opposed to metal.  This will ensure you don't have to worry about rust degrading the structural integrity of the caster.

- It is extremely important to make sure the drill bit you use creates a hole that is the same size as the castor shank, or even slightly larger.  (If the hole is smaller than the shank, you risk splitting the wood when attaching the caster.)

- Use Gorilla Glue or a a similar formulation. This glue is incredible stuff, is waterproof, and will last many many years. Using more glue than the recommended 10 drops, may result in a big mess, so caution is necessary.

 

Method:

  1. Purchase three heavy duty casters rated at 100lbs or greater
  2. While in the hardware store, have the caster "shank" Sized by an employee
  3. Purchase a drill bit that is the next size up (1/64" - 1/32") from the castor shank diameter
  4. Purchase a very small squeeze bottle of "gorilla glue" (highly recommended)
  5. Place a mark in the center of each leg, and drill as straight as possible into each leg at least one eighth inch deeper than the total Length of the castor shank   b2ap3_thumbnail_1.jpg
  6. Pour enough water to fill each hole in the legs. After the third hole is filled with water wait five seconds. Now turn your Garden Tower (or legs) right side up to drain all of the water out b2ap3_thumbnail_3.jpg   
  7. Add about exactly 10 drops of gorilla glue into each hole, on each leg   b2ap3_thumbnail_4.jpg
  8. Using a mallet (or hammer and a small wooden block) Push or gently tap each caster into its respective hole until it is completely seated (in as far as possible)b2ap3_thumbnail_5.jpg
  9. Using duct tape, ripped into thinner strips if necessary, secure each caster onto each leg. (This is necessary, because the glue expands several times over while drying and has the potential to force the caster out of the hole.) If you sized your drill bit properly (it was not difficult to get your caster securely embedded in the hole) then simply tipping your Garden Tower right side up will ensure that the casters are not pushed out by the foaming glue.   b2ap3_thumbnail_6.jpg
  10. After about three hours wait, any excess glue that has seeped out of the hole can be easily removed with a sharp utility knife   b2ap3_thumbnail_7.jpg

Again, for HARD and LEVEL surfaces only.  This procedure is not an official recommendation of the Garden Tower Project.
