I bought a Rupes LHR12E a few months ago and it's great. This comes with a 5" backing plate. If I wanted to use a smaller pad (and stay with Rupes) , then I had no other option than to buy the LH75E. But as I wouldn't be using this that often this seemed a bit extravagant so I decided to try and make a backing plate on my 3D printer that will allow me to use the pads that the LHR75E uses. This 80mm diameter backing plate has been designed to be the same weight as the standard Rupes 5" (125mm) plate so that there are no vibration issues - watch here for weight comparison • Video . As the plate has a much smaller surface area than the 5" plate (but obviously still uses the same motor) I have noticed less tendency to stall. Although, to be fair, the machine is pretty good in that regard as standard; it's just better on the smaller pad. The plate is tapered so it still covers the mechanism but I have also allowed for a small clearance between the plate and the rubber sleeve so this design basically incorporates the popular washer modification without needing the washer. This further reduces drag on the plate. (The plate also fits the Rupes LHR15ES & LHR15 Mark 2/3.) It works very well. Review here www.detailingw...
I hope you enjoy this and I look forward to reading your comments. Don't forget to like and subscribe if you aren't already. Thanks for watching.
p.s. Thanks to my friend Alan W, who offered advice and feedback in putting this backing plate together.
