If You get one of KJ's blades, make sure You get His mandrel too, for 10 bucks you can't go wrong, the one I got from him runs dead nuts compared to the slot cutter mandrels the hardware stores sell. I have several of those name brand mandrels, and the one He sold me gives all the others I have the 6,7, and 8.
I can't sit here and honestly say if each and every mandrel he sells runs as true as Mine, but I have no reason to believe different, as I've only heard good things from others about them, but I can say I was very happy with the one He sent Me, and even more thrilled about the low pricing.
I would try to answer the original question, but there are others who are more familiar with that lathe then Me. One of My lathes Is a Porper but It's a totally different model, and wouldn't apply to the question. I made My own dremel mount for My deluxe, and also have the option of using the 1/4 trim router with 1/4 mandrels like the one KJ has, because they don't fit in the smaller rotory tools, dremels only have a 1/8 collet.
