TS55, CT-Mini and MDF Dust- How's that combination?

[Hoover]

Sounds like your project is for your own house.  In that case, I would definitely do the cutting inside, or maybe just to simplify the logistics of getting the material to the inside location, break down the sheets a little while outside, but make the final cuts inside.  I hate trying to carry big heavy sheets in tight spaces.

I'm thinking I may break the sheets down for width outside in the driveway on a cutting table, and limit the inside work to just cuts to length on the MFT and assembly.   That'll prevent dragging full sheets into the house, while still keeping most of the work inside.

You beat me to it.  Just do the bulk cutting outside then move the operation inside.  I would the bulk of the cutting outside just so I have smaller lighter pieces to move inside.  MDF sheets are so heavy and difficult to manage, going through doorways, up stairs, etc. is a PITA. 

I have the TS 55 and CT 22 combo and the 22 has a bit more section power than the mini, so I can't comment on the mini specifically.  The 55 and 22 combo works perfectly for mdf.  I absolutely hate cutting mdf because of the dust and once I used the TS on it, it didn't bother me at all.  The cutting of mdf or birch plywood will be pretty much insignificant.  One piece of advise.  Take a look at the CT 22, the weight of the 22 isn't much more than the mini.  To me the only downside of going 22 over the mini is the extra cost.  There are plenty of upgrades with the 22 over the mini.
