I have the hitachi 8-1/2" SCMS. I have posted previously that the DC is very poor and it takes up way too much space in my small shop.
I have tried using the Festool boom and the 36mm hose with poor results. I fooled around a few weeks ago using a 4ft length of 36mm non static from CT 22 to a 5gal bucket with a cyclone top. Another short (about 6 or 8 ft) section of 36mm from bucket to the SCMS. This without the boom but keeping the hoses running on floor so there was almost no lift involved. This produced reasonable DC. Not perfect, but much closer to satisfactory DC.
I ran across a TV slide/lazy susan meant for large TV. I had used it in the shop for something else and got an idea to give my SCMS a smaller foot print. I used some scraps of 3/4 ply and made up a cabinet (definitely not an artistic example) with the slide/rotary plate on top. I mounted a flat piece of plywood (18" x 28") on top of that with the SCMS on top of that ending up with work surface of the saw about 1" higher than my MFT 1800. With the saw swung to 45? and the table backed up against the wall, it only comes out 18" onto the floor space. I have not filled in between wall studs so When I swing the saw around for square cuts, I have an extra 3" (2x3 studs) behind as I pull the table forward and push the saw carriage all the way back. I can also set the saw base perpendicular or at an angle to the wall and use my MFT as an infeed table. I have not worked out how to attach infeed/outfeed surfaces & fences to mount permanently. I also need to work out how to somehow lock the saw into whatever position i need to use it. That will be my next project. More scraps to use up.
Nothing pretty, but I figure i just saved (when all problems get worked out) over $$$1300 ;D that i can spent on other toys.
The MFK 700 and a few 8mm bits pops into mind for starters. Of course, I plan to try the Edging Plate for OF 1000 Don't have the part #, but "Uncle Bob" tells me such is available. If that works and I don't need the MFK 700, I have several other goodies in mind. Of course, saving all of those $$$ with my ingenious :

table invention and figuring how to avoid spending more for the MFK by using the extra guide accessories for the OF 1000, is no guarantee against weakening resolve not to end up going for a Kapex or the MFK. So I'm a weak man. ???
