We have developed a build-your-own moulding sanding system by using a custom made arbour, along with our sanding mop sheets. The sanding mops are stacked onto a shaft to create a 7" moulding sander head. Various grits are available. You can buy a Moulding Sander kit and use your own creativity to build a box and or adjustment mechanism to meet your own unique needs, or buy a Moulding Sander with the Bracket Assembly which comes with all of the adjustment hardware to set your sander into. Either way you'll have your very own moulding sander for the fraction of the cost of a commercial unit.
