I was looking to find an answer how to use more efficient the mft 1800 and the TS55 and I found this post.
Last night I promise myself not use the TS55 and MFT 1800 together again. I found it very slow!!!. I can do the same with my TS Unisaw and much faster. The accuracy can be obtain in the MFT 1800 and TS55 but it takes to long to setup vs my table I have just to move my Biesemeyer to the size, hold and tight the lever and I am in business.
I don't have the boom arm and the hose/extension cord is driving me crazy. If I want to make another cut I have to put the saw away, move the hose/extension out the way, lift the guide position,position the wood and move the TS55 again (Damn the hose/extension cord is on my way again

).
I work in my 2 car garage and I am a hobbyist so I need to keep the MFT 1800 folded so my wife can park her car. So I have to setup the MFT 1800 every time I want to woodwork. It irritates me. I will use the MFT 1800 for everything else, assembly, gluing, router operations but not with my TS55. I will use my TS55 and guides to cut plywood into manageable sizes. I will rip with my Unisaw and the crosscut with my Incra Miter 5000 and Unisaw.
Also the power of my Unisaw (220v) vs TS55 makes my cuts faster.
I own several festool tools and I know the quality of them (Domino, OF1400, TS55, MFT 1800, RO125) but I cannot understand how the TS can be replaced. I understand the point of working at the clients and MFT 1800/TS55 better use in that situation, but I am a hobbyist and all my work is for my wife.
Something positive is I will never use my Unisaw to cut full sheets of plywood. My TS55 and guides are better suited for that.
