648Re: 'sawhorse' trestle tables
- May 12, 2003Hello Colin,
I want to start by saying your web page has fantastic wood furniture.
I've made a few knockdown trestle tables using slots and datos but
they get loose quickly and wobble. I believe you have a picture on
your webpage of a trestle where the cross piece is aligned up and
down and your pin passes through side to side. Last night I was
working on this wobble problem and cut a mortise for the pin to go
top to bottom. The way it holds over a larger area of the leg and
seems sturdier than the cross pin. The other thing I did was cut the
pin's mortise at an angel to match the pins angle. This gave a
larger area of contact inside the mortise and the leg stopped
wobbling. The material I'm using is 7/8" maple. The cross piece is
5" wide and the tenon is 3" wide x 4" long. I didn't cut a shoulder
for the tenon because I felt the material is too thin. Once the
mortise was cut in the leg, I then cut a 1/4" mortise in the tenon
from top to bottom. Having the mortise go straight through and using
an wedge shaped pin meant that only one small spot of the pin was
contacting the instide of the mortise. I then took out more material
to make the mortise angled and I recut my pin to match the angle and
keep it short enough to stay below the tabletop when in place. Now I
have a lot of contact in the mortise which puts pressure on the top
and bottom of the tennon. This removed most of the wobble. There is
still a little side to side wiggle, but I will probably glue small
blocks jsut below the base of the tenon to act as shoulders and that
should reduce that movement.
I'll try to post some pics on my webpage this evening.

section. Assuming this test works successfully, I'll be fixing or
replacing my existing trestles to this design.
If someone else tries this or sees an obvious issue this this design,
please let me know.
