0.720

3/4" MDF Table Top
Split a full sheet down the middle and separate as shown and
provide a filler piece if desired, or cut to length as dimensioned
and use the remaining material for the spoil board.

3/4" MDF Spoil Board

Attach from below and then use the router to mill the
surface flat. This board will be replaced from time to
time so do not permanently fix it to the Table Top.

0.720" x 0.625" plywood strip
This locates the angle iron track as
shown and supports the roller chain.

Match drill and through-bolt both

angles to the Table Top

The edges of the Table Top, and more

importantly the angle iron tracks, should
be as straight and as parallel as possible.

2.250

2x6 lumber shown

The Table Chain Boss attaches here.

Recommend using (2) pieces of laminated

plywood to achieve a long straight beam. For

long tables, increase the height of this beam.
