Hi guys. I have just purchased the ready2rout router table lift and fence combo from timbecon for an absolute bargain. I have decided to use a 3kw water cooled spindle in the lift. However the lift requires a diamter of 106.7mm and the spindle i was looking to buy was 100mm. I have read the forums and discovered that dalejw used thin strips of aluminium to pack out his router 1.8mm. I was wondering if i used 0.5mm aluminum and stacked them if that would work or if there is an alternative product to buy that helps to pack out the gap of 6.7mm. im looking to do it for as cheap as possible but i want it to be safe and secure. Thank you for you help. I have attached the spindle i was looking to get. cheers
