Yesterday I was using my TS 55 and then my mother came home from work and she wanted to help me do some finishing work. I dont live with my mother still if you were wondering, im actually fabricating her kitchen cabinets and using the garage as a shop. Anyway, I have my plug it cord, the one that came with my TS 55, taped together with my CT 22 vacuum hose. I do this so its easier to maneuver around the workpiece, less hangups. So I went to give it to her to use with the ETS 125 and it works fine. The problem is then I open my systainer for the ETS 125 and go to plug it into my TS 55 and it will not plug in due to a little bump on the ets 125 plug it cord. Well I was wondering if there is anything different about the ETS 125 cord than the TS 55 plug it cord, because if not I was going to cut off the bump with a razor knife and then it would plug into the TS 55. Thanks, Oh yeah I also have the domino and the plug it cord is the same as the ets 125. So needless to say, I couldn't cut with the TS and have my mother sand with the ETS simultaneously, unless i untaped the TS 55 plug it and the vacuum hose, but then I would have to change it yet again when I go back to cutting sheets with the TS. This was a real bumber and I almost cut the little bump off but I wanted to check with you guys first.
