![]() It is quicker and cleaner than screwing it down. Pneumatic staplers can be rented for the few hours. Something long enough to get good grip and wide enough that they don't pinch the skating surface. If you are using masonite a pneumatic stapler will give you the best finish. The heads can pop off and you will have to replace the screw. ![]() They are weak and will wear just from having a skateboard roll over them. It is best to use ones that are threaded all the way up the neck for the sheathing. If you want to get picky you can use 3" deck screws for the structure and 1" ones for the sheathing. So you can take them out and put them back in for repairs. They have a Robinson (square) bit that does not strip. The materials vary depending on what is being done.įasteners I use 1 1/2" deck screw because they are strong and durable. The sky is the limit for other tools too. If you have a little more money then get a miter saw and a chalk line. If you are good with tools you can get by with that. Due to the logarithmic nature of the scale this represents a 50% diminution in sound energy.Tools A most basic set of tools to build: The sound absorption properties of the foam in conjunction with the above effects served to reduce measured sound levels in the vicinity of the ramps by at least 10dB. The sprayed application which penetrates all nooks and crannies coupled with 25 fold expansion of the foam ensures that all potential air gaps are plugged minimising airborne sound transmission from the underside of the ramp and surrounding enclosure. Provides strength and sound-insulation and cuts out unwanted air leakageīeing physically attached to the wooded/metal surface the material dampens the reverberation after an impact. More efficient and a better fit than cutting foam-boards Spray foam insulation has the following advantages over other sound proofing methods: The measurement of 10dB difference represents a reduction of half the sound energy. After applying sound absorbing spray foam a peak reading measured a SPL of 86dB with over six times the amount of activity by the skaters. Sprayed on insulation can also help to dampen the level of the impact sound produced as the skater lands on the ramp.Ī detailed survey and monitoring of the activity recorded a peak reading of 96dB upon impact by the skaters. Reducing the vibration associated with the activity on the ramp in turn helps to reduce noise. This helps reduce vibrations caused by skaters on the ramps. Revolution Ramps optional sound proofing is achieved by applying Spray Insulation foam to the underside of the ramps. The Ramp coping is made of 50mm o/d aluminium tubing with a 5mm wall Optional surface of 1mm thick coated steel sheet can be used as a surface at an extra cost. Ramp surface is manufactured from 2圆mm thick treated plywood sheet that is screwed then bonded to the wooden frame to provide a continuous riding surface. Handrails are manufactured using 30 x 30 x 2.5mm square steel hollow section for the frame with 16mm round solid bar welded vertically to the frame with 100mm centres.Īll handrails to be shotblasted, zinc rich primed, then a finish coating by way of polyester powder coating. Transitions on half pipes, quarter pipes, etc are manufactured using Treated CLS Timber (L)2400 x (W)89 x (T)38mm.Īll frames to be twice coated with wood preserver, and once coated with Polyurethane alkyd resin Ramp frames are manufactured using Treated CLS Timber (L)2400 x (W)63 x (T)38mm, and are boxed in using 18mm WBP Exterior Plywood.
