MFT/3 table - underside clearance?

[Midnight Man]

Thank you to anyone who can offer some insight here!

I am in the process of designing a new workbench, and I would like to put an MFT top on it - I have a Parf Guide system coming to do that with.

Part of my design is to include a flat piece underneath the MFT top to catch dust and other items that might fall down.  The MFT top itself will be loose - held in on the sides by a rebate only, so it could be lifted up to clean underneath and retrieve items.

My big question is this - how much clearance underneath the table do I need to allow for general day-to-day use?  Never having used and MFT, I have no idea myself, and want to allow enough room in my design.

Thank you for any wisdom you may be able to share!

I did something like what you are plannng. I left about 3" under the top to allow inserting the Festool clamps. The clamps angle in and need a bit of clearance. You might get by with less than 3". I'd recommend buying a few of the clamps and measuring the required clearance. You will enjoy using the top with the clamps and  Qwas dogs.

Many thanks Birdhunter

I was planning in my design to allow around 80mm gap, which is a slight bit above 3 inches - so it sounds like my plans are reasonable, sincerely appreciate the confirmation!
