It can cause the mandrel to bend and cause a dangerous situation. And I have seen the sand paper unravel, but there was more to it than just the speed.
Melissa, when washing in between, is it sufficient to just dip in a sudsy bowl, rinse, dry and then move on, or do you need to take to sink and rub with soap? TIA
That is a really good question. Taking it to a sink is probably best. But as long as you get all of the compound off between stages, you should Be good with what you are doing.
Make sure it is nice and dry, and use a different cloth to dry for the different phases so you don’t accidentally put some abrasive particles back onto the piece before moving on.
