Can I replace the 6" backing plate with a 5" bacing plate? If so, can I use a US industry-standard backing plate (I believe they use a 5/16" - 24 stud).
It is not recommended to replace it because the weights of the counterweights on different plates are different, which will cause the machine to vibrate more.
The product will be out of stock for a few months. It is recommended to add it to your wish list and you will be automatically reminded when the product arrives.
