Here some answers.
"I understand you purchased parts of the CMS TS 55, not the entire kit (you seem to use the MFT Fence)."
I have a complete CMS with TS-55 - I use it when I work outside the shop - In the shop I use the MFT fence and the CMS fence. See the page of spare-parts, for ideas.
"Why did you decide to make the plate into which you integrate the machines, so large?"
I wanted it to be the same size as the standard CMS modules.
"Could it be smaller in order to save more place for the 'regular' MFT use? "
You can make it smaller, when we are talking about PS300/PS400 and OF1010. - I have put the PS300/PS400 in the middle of the plate - you can place in one of the sides. This will give you more spaces.
For the TS-55 - Use the original version from Festool - it has all the safety you can get
"I'm not sure I understand how the alu pipe was made and is being used"
Here are some extra pictures - hope the explain what I have done - If you are lazy, and want to spend some money, you can buy the following spare parts from Festool - and you will have a very nice result.

Festool - has a stand kit for this route - and I haven't had problems. (and my is the old one with only a 720 watt motor)
"Can you explain a bit more how you made the lift (pictures would be great)?"
Here are some pictures - hope the explain - how I did - else write back.
"How easy is it to 'plug' the router on the plate?"
It take about two minutes, and this is okay - but it will be more nice if it was more easy - I working on a solutions for that - I expect to publics this solutions during the February.
Thanks for you response at my solutions.
