Building a rig

Spent some time today building a slider rig, after watching a video of how somebody made their own at a fraction of what I would cost to buy a professional one using nothing more then some bits of wood, screws and a drawer runner I attempted to build one myself. I dug out some old scraps of wood we had as well as bits of MDF and cut them down into various sizes to act as a stand and balance for the rig as well as acting a platform for my camera I also managed to find a quarter inch screw that just about fits in my camera but doesn't thread right in. The next thing was to get a drawer runner so after a quick trip to the screw fix round the corner I got the longest drawer runner they sold and proceeded to attach it all together as you can see in the picture. The rig isn't completed yet, as i discovered that the original place I mounted the panel for the camera results in some instabilities. So taking that into consideration I need to mount it on the opposite side that will take some more screws and boots which I will be purchasing tomorrow. Hopefully it will come together nicely as just by playing around with it already I can tell it should work nicely as the runner is very smooth and with a little lubricant will only make it a smoother slide. I also purchased two 500w work lights with a stand today that will be coming on Monday and the good thing is it comes with a stand. I'm hoping it will serve as a light source for when I finish Uni and have know means of getting lighting without buying it. Some of the reviews say the bulbs go quick but I have been looking at for replacing them with professional bulbs if they are available and will work with it. Tomorrow shall tell whether the slider works anyway and I shall post pictures and what not with it in action.
