What you will need
A picnic table, old or new
A piece of sheet steel
Steel weldmesh
Thermal insulating fabric and fire bricks
Lengths of timber
4 x M8 bolts, long enough to go through two thicknesses of timber
Hand saw and jigsaw
Quick release clamps
Powered drill come screwdriver
Angle grinder with steel cutting blade
Marking tools, such as a straight edge, measure and square
Hammer
Self-tapping wood screws
Personal Protective Equipment
Safety glasses
Protective gloves (EN388) to guard against cuts and burns
Wear ear defenders when using angle grinder
Safety notes Always take care when using power tools and, as a precaution, have a first aid kit to hand. Work on a stable surface,
in good light. Wear all personal protective equipment and suitable clothing. Construction can take place indoors, especially if the
weather is inclement. However, all fires should only be lit outside, in a ventilated area that is a distance from structures, or other
things, that may catch light. The grill and mesh will get hot when in use and should not be allowed to contact bare skin. Keep water
and/or fire extinguishers to hand, in case of uncontained fire. Those under the influence of intoxicants should not engage with this
project. You will need to carry out appropriate risk assessments, should you intend to undertake this project in public areas, such as
parks, or camping grounds. Also ensure that it is legal for you to do so. If any injuries, or burns occur seek medical advice.
We’ve all seen picnic tables in gardens, pubs, parks etc and with their integral seating, they are convenient.
Unless you use a wheelchair. Jimmy wanted to convert such a table to make it a bit more accessible. Using
simple carpentry techniques, you can give yourself the choice of removing the benches and creating more
table space. The addition of extra timbers to the bench seats and table legs, using the saw, screws and
screwdriver, allows this to be done.
Once the seat supports have been extended and a brace bar installed to hold them at table height, drill
holes for inserting the M8 bolts, at both levels. These will secure the extensions you have made, when
being used as seats, or table extensions.
Cutting the grill into the table top, needs to be a compromise between creating space for a decent amount
of coals and keeping enough of the table for the comfort of your guests. We used the jigsaw to remove
the two central slats, as close to the support bar at each end as we could. Use your marking tools to
ensure that the hole is square to the table top. Keep the bits you cut out for use, later.
Mark out your sheet steel, in preparation for forming it into a box for the coals. Mark the base of this box a
centimetre, or so smaller than the hole that you cut in the table. This allows for the addition of the thermal
barrier, which will keep the table and your guests from being burnt by the grill. The box sides need to be
the depth of the slats that were cut out. Mark a few centimetres extra on the sides, to form a lip at the top
of the box. This will make a neater fit to the table.
Wearing your protective equipment, use the angle grinder to cut the lines you have marked.
Use the clamps and the wood you cut out of the table top, to hold the steel against the table edge. This
will give you enough resistance to bend the steel into a box shape. The hammer allows you to form a crisp
edge.
Now, utilise the table cut outs, plus some of the extra timber, to build a support for the grill box. This will
also protect peoples’ legs from heat. Clamp the wood in place and secure with screws.
Cut the thermal insulation material, so that you have just enough to line the containment that you have
just created. Gloves will be essential.
Cut the mesh to size, to support the food.
Light the charcoal, as you would for any barbecue, then assemble the delicious food that you will be
cooking. One person can be chef, or everyone can cook their own. You’ll certainly be close enough to
achieve this with comfortable ease.
Job done.
