Welcome to Ask the Expert. We've got a question here from Floringford and Muldover, I believe. Floring says, I can't remove welds very well with vortex rapid blend. What am I doing wrong? OK, so this is the vortex rapid blend, is that the floring is referring to. Now, this is what from our nonwoven rage, and it's actually made from what we call unitised material. It isn't enhanced by having the vortex cranium here, so it can remove more material than a standard unitised disc, but really this is not the product for weld removal. This is more for blending and finishing the surface of a product. When you're wanting to remove welds, you need a little bit more material removal than this will give you. So you need to be looking at using something like a flat disc or a fiber disc for doing that. If you try and remove the weld with this disc, you will wear it away too quickly. And it was not the disc for the job at all. So use your flat disc for taking the weld off, then switch over to this disc, because your second step to take away the grind lines that have been left with your flat disc. So two step application, you'll get it done much quicker and end up with a much better result by doing that. Hope that helps you, Floring. Any more questions? Pop them up down in the comments below, and we'll try and get back to you with an announcement soon as we can. Bye-bye.
