Introduction: Wet Sponge Throwing Board

Hi everyone, thanks for taking time out to visit our first Instructable.

We have been fans of this site for a long time and when asked if we could make a “Wet sponge throwing board” for a charity event, my wife and I thought let’s pass on what we learnt along the way and share in the fun of making it.

Must confess we have never made one of these but in our little workshop we love a challenge and set about to draw, design and make one. The remit we had was to make it look like an old-fashioned fair ground attraction, colourful, practical and must have a “strong man” image on the front, the rest was up to us, so here we go folks this is how we did it.

Step 1: Materials Used

1 off - 8 x 4 sheet

of 18mm MDF (cut down to size at the DIY depot)

3 off - 47mm x 75mm x 2400mm studwork timber (photo for reference only not quantity amount)

2 off – 100mm x 15mm x 2000mm PAR (planed all round) timber

Various size timber screws

2 x 110mm M8 bolts with nuts and washers to suit

Undercoat white paint

Red / Yellow/ Black/White Outdoor paint

1 small tin of outdoor varnish

Step 2: Tools Used

Jig saw

Battery circular saw – (not necessary if DIY depot can cut MDF to correct size)

Cross cut saw (Not necessary could use hand saw if you want)

Drill and bits to suit screws & M8 bolts

Set square/ pencil/paint brushes

2 clamps

Step 3: Planning

Our first thought was how big should the board be? It was

for kids to throw wet sponges at their parents and teachers a standard UK door size would be about right around 1981mm x 762mm however after some debate it seemed a little to high and a little bit to narrow so we settled on 1800mm high x 900mm wide that way the poor adults would get some relief from straying wet sponges from the side.

We had to think about a quick and easy set up and pack away of the board and thought some sort of clamping system would be best, see below for stand design.

After some time, we had a plan in mind and set about making our board, below is how we did it.

Step 4: Making the Legs

Firstly,

Cut down the 3 x 47mm x 75mm x 2400mm studwork timbers into 4 equal lengths (600mm)

With an off cut from the original MDF board, sandwich this
between the stud timber, measure total depth of stud timber plus MDF should give you 112mm, take an off cut of MDF and trim down with your saw to 600mm in length x 112mm width, you need 2 of these (1 for each side of the legs)

Step 5: Making the Legs

On a flat surface lay out your stud timbers with an off cut

of MDF sandwiched in between both, check your timbers are level both ends and clamp/screw your 600mm x 112mm MDF board to the sides of the timber using 35mm long screws (again do same for the other leg)

The last photo is what you should end up with

Step 6: Making the Legs

Take the 2 off 100mm x 15mm x 2000mm PAR (planed all round)

timber and cut into 1200mm lengths again lay onto a flat and stand one of your legs on the top.

With the remaining 600mm stud timber lengths clamp 1 to the back of the leg at a 45-degree angle and mark 2 cut lines (1 top 1 bottom), transfer this mark to all 4 lengths ready for cutting. Once cut attach these to the leg uprights. You should have now 2 legs with timbers attached to slot board in. Apologizes didn't get a photo with the bracing timber on.

Paint the legs in any bright colours you wish, we used 2 coats of white under coat first and 3 coats of red / yellow & black to jazz them up (the sky’s the limit on how you paint them, big and bold is beautiful) finish off with 2 coats of outdoor varnish.

Step 7: Making the Board

We gave the board 2 coats of white under coat both sides,note~ don’t forget all the edges as we want to keep as much water out of the MDF as possible. Once dry we gave another 2 coats of Satin out door paint again do all the edges.

Drawing the strong man onto the board took some thinking
about, how high, wide ETC in the end I got the wife to stand next to the board and mark where here chin and top of her head was – You can use a projector (very cheap ones can be obtained from Ebay or off the web) which we did try, however the wife is great at drawing so she sketched the outline in pencil and then painted the image onto the board outlining it in black. Once complete she handed it over to me to cut the head and hand parts out with a jig saw. Take into consideration head should be big enough to be able to put any head in and out without getting stuck or taking your ears off when pulling out the hole quickly.

Once all cutting is done dust off wipe down and give the board 2 coats of varnish all over.

Step 8: Putting Together

Simply stand the board up and slid anyone of the legs over

the board, do the same on the other side and your board will stand firmly up. Important note here … We tried to tip the board over on purpose a few times to test it out and found sometimes a leg would slip off the side so for safety I drilled 2 holes (1 either side) through the leg into board and out the other side. Hole should be big enough for the bolt to pass through easily and insert a nut finger tight to hold it in place.

There you have it a “Wet Sponge Throwing board” for those summer days in the garden with the family or in our case a charity event to raise money for a good cause.

Have fun folks, thank you for stopping by, take care be safe, but above all have fun.
