Thanks for the info! I just bought a 4x8 of HDF for $78USD which I will drill & route into an extra large MFT sometime next week.

Would you please indicate the height and width you used.
Thank you.

They're actually 8 foot long. 12" wide, 6 3/4" deep.
About to rebuild with the following changes:
- no internal partitions (they get in the way of the clamps )
- bottom skin instead, large openings on side like Ron Paulks design.
- will still have one side with 20 mm holes
- top laminated with Formica for resistance to glue , water, finishes
- holes now 3 rows at 32 mm spacing, maybe 4.

I have not got around to doing it. Thought I would get it done when I had a couple weeks "between gigs" last month, but so far that CNC machine (for guitar building) has been sucking up all my free time (finally over that hump), so will get to it soon.

Almost 2 years ago you considered changing your beam bench specs.
Did you change and if so how do you like it now?

Interesting test. Thank you.
I thought ply was less stable than MDF. Are you using ply for a work bench top?
//Michael
Festool uses a denser version of MDF called HDF, which in their case is custom made for them.
My cutting table does not need to be especially stable, so I use 19mm cabinet-grade plywood which for one reason or another was not attractive enough to use for cabinets we sell. I consider this to be a sacrificial surface, so stability is not inportant to me. On the other hand, I find my saw blades stay sharp longer cutting into plywood as opposed to MDF or HDF. On my CNC nested routers I use LBO, mostly because the machines can pull enough vacuum through it to hold the actual work in place. Sometime the task on a CNC router cuts through the work. LDO works for me because it does not dull the tips of the router bits as fast as plywood or MDF, but those would not work anyway because they block the vacuum action.

I'm not sure where it started, but I hear many Festool owner's have come to believe MFT tops are made of "HDF" or some other "special" material. They are plain old MDF; that's not a bad thing. I have yet to hear a reason why HDF would create a superior top surface. It would be more abrasive to bits & blades, less forgiving to your work (denting & scratching) and more difficult/expensive to replace. I contacted Festool customer support to verify this and their response was:
Hello,[/size]Thank you for contacting Festool. The tops of the MFT tables are all simple MDF tops that are not Hard Density Fiberboard or treated in any way.Best Regards,_________________________Festool USATooltechnic Systems, LLC400 N.

TheSergeant said:I purchased the Festool 20mm bit but wasn't happy with how sloppy the fit was with my parf and precision dogs. I ended up just using a freud flush trim bit and duplicating my MFT3. On a whim I ordered a 20mm generic forstner bit from china off of amazon for like $5 shipped. I was pleasantly surprised by the quality and sharpness of the bit. The size of the holes is actually spot on perfect. Maybe a hair tighter than the MFT even. I made a jig to keep the bit vertical and will just use a hand drill. I haven't made another MFT top yet but will in the next few weeks.
