  • Shelves

    Today we sliced up 10 sheets of 18mm OSB boards into a whole collection of shelves! We planned to have 600mm deep shelves for our boxes on the right side next to the sheet material racks, along the middle wall a load of 400mm deep shelves (5 layers from floor to ceiling) with a narrow 200mm deep shelf at the top just under the Light Channel. And finally on the left side of the room we will have the workbench in the corner with 800mm shelves underneath and a series of 200mm followed by two 400mm selves above.

    We have finished putting up all the shelves onto brackets , screwed them into place and surformed and sanded the edges to take off the worse of the sharpness and splinters!

    We can now start moving our tools and boxes of “stuff”!

  • Light Levels – final conclusions

    we did some more illumination tests

    and discovered that the reading is now 325lux, a drop of about 5lux after we have painted the ceiling with the Absolute White. We concluded that the finish was a matt surface and not the silk as before so we guess that Dulux was comparing the advantages of Absolute White against other Matt finish paints!

    But having said all that, we also concluded that the ceiling is less harsh to look at now and gives a more satisfying glow!

    We think this is well worth the drop in the brightness level of 2%!!

  • Utility Rail backing strip

    We put in the 100mm wide strips into the back of the Utility Rail to cover up the glass wool. We will use shoulder dresser hooks or in other words L shaped hooks!, to provide anchoring points to keep separate the different types of cables running inside the Utility Rail. The regulations require that the mains electricity cables must be kept separated from low voltage cables like network, audio and such things like that. We would use the L shaped hooks to lay the cable across and if necessary we could put a thin board of some kind to provide a little shelf!

  • Paint Glorious Paint!

    The final coat for the ceiling was put on this morning! The special flavour paint came yesterday and we collected it from Jewson, called Dulux Absolute White! It is stated to have even more whiteness than brilliant white! According to the dulux’s web site, it can achieve 90% reflectivity against 80% for brilliant white! We will see tonight, the results we get when we redo the light tests.

  • We Have Lights!

    All ten tubes are up and installed right around the Light Channel in the large front room of the Garage. Each T5 tube produces about 5000 lumens as stated on the manufacturer’s data sheet and consumes about 60watts using high frequency electronic ballasts. This gives an efficiency rating of 83 lumens per watt which is about double the required rating in the building regulations.

    So in total there would be a maximum of about 50,000 lumens! The size of the room is 8.2metres (26.5 feet) wide by 5.75metres deep (18.5 feet) and the ceiling is 2.5metres sloping up to 2.6metres (over 8feet), which is a large room!

    After dark, we did our light tests again and the light level this time is 330lux on exactly the same spot as yesterday but we discovered that even with us in the room, it changes the readings quite markedly so yesterday reading must be taken with a pinch of salt and probably a bit on the low side. Today’s readings were achieved using the built in feature of the light meter of recording the maximum value while we all left the room entirely.

    Taking further measurements around the room at a fixed height of 1metre, the brightest (440lux) spot was in the corner next to the internal wall furthest from the small door, and the dimmest (200lux) was at the middle of the front wall.

    Dimming the tubes down to their minimum level produces a low gloom measuring only 7 lux! But there is enough light for walking around but not to read by. Nice to relax in and watch TV etc.

    There wasn’t any flicker at all at any brightness level.

  • 4 out of 10 Tubes done!

    The electric cables (mains and control lines) are in place inside the Light Channel. Four of the 10 tubes are installed. A light switch is wired in beside the internal doorway and we can dim and turn on and off the lights! So far so good!

    We have placed the light level meter in the middle of the room and it is reading 122lux at the moment. We will test again tomorrow night when the remaining 6 tubes are installed.

  • Paint 6!

    The final touch up on the metal uprights is done! At last! It is looking as if the rust problem is solved! Hurray!

  • Electrics for the Lighting

    The lighting wiring has been started today for the ten fluorescent T5 tubes, controlled by five electronic dimmable ballast. There will be a momentary switch control to operate the dimming feature, done by supplying a mains voltage to the control port. A quick press of the switch will turn it on and off and holding it down will start ramping up or down the brightness level. The brightness level is remembered upon switching back on next time as long there hasn’t been a power cut! Another advantage of this method of controlling the lights, is that we can have several momentary switches besides the door entrances and any one will do the job! this might include a PIR sensor in the room which will trigger the light on!

    Cannot wait to see how well the lights will shine from the Light Channel!

  • Paint 4!

    Today we paid attention to the problem we are having with some of the metal shelving uprights. We rubbed them all down to get down to bare metal in some cases but mostly to roughens the surface ready for another coat of paint but this time White Hammerite! This is now done and hopefully we have solved the rust leaking problems. When we do the third coat of emulsion on the ceiling, we will touch up the metal uprights to bring them back into line with the rest of the room!

  • Sliced 2 by 4 timber

    We had the table saw outside today so we took the opportunity to slice the 2 by 4 inch timber diagonally down the length, to produce a sloping edge shaped piece, two of them. These will be used on the roof to create an edging right around the perimeter to form a dam to push the rain water down and into the rain drains. The rubber membrane will be glued up the slope and fix down with aluminium grip bars on top of these rhomboids we have made today!
