I have bagged mine after cutting them but when I started this the wife had an old cooker (see pic) that she wasn't using so she donated it to the cause. I was concerned about melting wax and the possibility of fire but this cooker has a thermostat and if I set it to warm it melts the wax perfectly. Also, I've put plenty of wax into the pot to get it deep and make it very easy to dip the wheels one side at a time. Just have to chill them first. Works, and looks, great.
