Krackle Posted December 17, 2018 Report Share Posted December 17, 2018 Hi, first post here.. Im about to start into a major renovation of a space in my building..Part of this involves building some cabinets. This is my first step into building cabs..they will be basic ply boxes with plywood slab doors, probably Birch finish. Im interested in building a simple, flat and squared up assembly table. In my experience most decent quality solid core slab doors start out pretty flat.. I was thinking of using a 1-3/4" x 36 x 80" door and then topping it with a sheet of 3/4 MDF or so. Still sorting out a base for the table top..the floor in my basement is concrete, very old and not level or consistent. I'm sure some of you have done this..just wanting to confirm that it'll be close enough for assembling basic cabinets etc. I'll be posting at some point looking for some advice on the actual cabinets..for now though Im starting to put together a work area for this part of the project.. thanks!

wdwerker Posted December 17, 2018 Report Share Posted December 17, 2018 The most important thing will be building a flat square & level base. Shims or adjustable feet will work. Checking the door before you take it home with a long straightedge and an accurate square is smart too. Most stamped sheet metal framing squares are not as accurate as you might think. Check any long straightedge with a high quality long level switching sides and direction to see if there is any gaps. I use playing cards to see if one will fit into a possible gap. I would only screw the 3/4 MDF to the door so it could be replaced. Pilot holes should be pre drilled and the back side slightly chamfered, MDF is bad about leaving a bump around a hole on the back side. 1 Quote Link to comment Share on other sites More sharing options...
Tom King Posted December 17, 2018 Report Share Posted December 17, 2018 I had one like that for a while. It was some really heavy, commercial door that started out really flat. After about two years, it had about a 3/8" sag in it. Quote Link to comment Share on other sites More sharing options...
wdwerker Posted December 17, 2018 Report Share Posted December 17, 2018 Tom is right a door only supported at the ends like on sawhorses will sag. A frame/apron all the way around and maybe a couple crosspieces in the middle will prevent sag. New construction lumber will move too much. Hardwood is a better choice even if you plan to assemble the frame & legs with screws. Quote Link to comment Share on other sites More sharing options...
Krackle Posted December 19, 2018 Author Report Share Posted December 19, 2018 HI Folks..sorry, been way from the comp. Yes..planned on building a decent base with center support. The sawhorse thing is def not an option. A slab door on horses would start sagging very quickly for sure. Thanks for your responses,appreciated Quote Link to comment Share on other sites More sharing options...
