I know I'm a little late here, but I figured I would weigh in with my experience.
I live in a Philadelphia row home built in 1953. The garage, which serves as my work shop, is 9' wide by 19' long. Since these garages are so small, most people use them for storing garden equipment and bikes and similar items. It's not impossible to park a car inside - my late grandfather parked his car in a similarly sized garage for 40 years - it is a struggle that I was never comfortable with.
In February of 2011 I put the full court press on my wife to get a Saw Stop. I work in IT, and my fingers are the bread winners. I also have four kids, now aged 4-12, who love to work with dad in the workshop (always carefully supervised). I had grown uncomfortable with my very well regarded Craftsman 22124 "Zip Code" table saw. I'm getting ready to hit the big 4-0 this year, so I was looking at protecting my earning potential. I've also struggled with a back issue, so breaking down big sheets of ply wood on the table saw had grown more and more difficult. You can imagine trying to handle a full sheet of plywood in a garage the size of mine and wrestling it into place and trying to get good results.
Sometime around 2007 or 2008 I purchased a TS-55. It was a very nice saw that made awesome cuts. I failed to make use of the system and didn't have dust collection to go with it. I also only had the 55" rail, so my ability to break down plywood was limited to sizing it to something manageable to put on the 22124. I wasn't aware of this site or I may have been ready to jump in with both feet sooner.
I was all ready to make the order for the Saw Stop when I thought about some of the things I had read about Festool over at Saw Mill Creek. I was also concerned about dust collection. I had purchased the Oneida Super Dust Deputy, and was pretty pleased with its performance when hooked up to my Delta AP 400. The down side was the amount of space used by everything. Another limiting factor for me was the lack of 220 service in my garage.
The Saw Stop I was going to purchase had a very similar foot print to the 22124. Every time I tried to do something that required walking past the table saw was an exercise in frustration. I had some shop built shelving on the wall perpendicular to the guide rail tube on the table saw. I wound up with less than a foot of clearance between the tube and the shelves. I had contemplated reducing the size of the tube because I hardly ever cut to the left of the blade. I could never bring myself to do it, however. I especially couldn't imagine doing it after spending $3500 or so on the Saw Stop. I had a crisis - permission to spend money but lots of buyers remorse and unsolved issues to get everything together before even spending a dime.
About that time I finally registered here after lurking a while. I decided to take the green ad blue route rather than the black and red one. Uncle Bob took care of me and I wound up purchasing a TS-75, CT-36, OF2200, and the MFT/3. I also purchased the parallel guides (P00108) and the parallel edge guides for both the TS55 and TS75(491469 & 492243). I wound up spending close to cost of the Saw Stop for the Festool gear based on last year's prices.
After selling the Craftsman table saw I had a lot of seller's remorse. I was slow to pick up the Festool system. I also found the small size of the MFT/3 to be extremely limiting. I purchased the must have accessories - the rail and Qwas dogs. The square layout of the hole pattern on the MFT is genius. However, I found that the hinge system for the rail on the MFT/3 was not working well for me. I tried every suggestion to square it up, but there was always enough play to really frustrate me. I decided to forgo the hinge system and rely totally on the rail and Qwas dogs - which made the small size of the MFT/3 even more apparent and painful for me and my work habits. By needing to use the holes to the front and rear of the MFT table with the rail dogs, I lost quite a few inches in cross cut capacity.
Earlier this year I embarked on a few attempts at a "super sized" mft by using various techniques posted here and talkfestool.com. I wound up adding an OF1010 and the LR32 system in order to make my own larger MFT type surface. It it s few inches shorter and narrower than a 4'x8' sheet of plywood. I trimmed a regular sheet using my TS 75 and the parallel guides to ensure square corners and clean edges, which are critical to the LR 32 system. It also helped to reduce the weight of the plywood. I had previously tried to create the hole pattern on my work bench, but totally messed up and wound up with holes that aren't perpendicular and also not in straight lines. The work bench top is only 1.5" thick, but it was too thick for the Festool clamps to work properly.
Once I figured out the LR32 and found some time to perform the MFT "duplication" work, the results were awesome. Since I am no longer limited by the proportions of the MFT/3 I am a much happier camper. When I want to cross cut boards that are 8' long I am in good shape. Since my MFT surface supports the full length of the board, I no longer have to worry about the off cut falling of the table. Yes, there are many other ways to deal with that issue, but I'm very happy with my solution. I also don't have to worry about the depth of the holes since the holes close to the front and rear edges are roughly 36" apart. I have plenty of cross cut capacity now.
I will agree to a certain extent that the parallel guides are a bit finicky, and it really helps to have to make lots of cuts of the same size. The way I personally worked with a table saw was pretty similar, however. I start with a rough idea and measurements for my projects, but usually adapt to how things happen as I work my way through. I always wound up "sneaking up" to the right cut before I was able to crank out a bunch of similarly sized pieces on the table saw. I don't see the parallel guides as being that much different for me. Once I get to the size I need, I can crank out several pieces with either the table saw (when I had it) or now with the Festool setup. The big advantage the table saw had over the parallel guides was the stability issue. I know there are lots of potential solutions for increasing the stability of the Festool parallel guides, and I will pursue one of those solutions in the near future. I am just giddy after finally having an MFT type table that is big enough to make my hobby easier. I wanted to have one success under my belt before embarking on the next solution.
Sorry this was so long, but I figured I would try to return some of the knowledge I've gained here. For my workshop and the type of work I do I can work without a table saw. There are times I get starry eyed looking at the various table saws out there, and I would have really enjoyed that Saw Stop I passed on. After having lived through the frustration of such a limited space I am confident that I made the right choice by going to a mainly Festool shop.
Thanks,
Justin
