How to Build a Halfpipe Skating Ramp

Monday, November 2nd, 2009

Not ready to show off your skating skills in public ramps yet? You can now build your own halfpipe skating ramp and start practicing BMX or skating in your backyard. It may sound complicated or difficult for people who do not have wood working experience. Read on as this article makes the entire process of how to build a halfpipe skating ramp easier to understand for beginners.

Based on the compound or space that you have, decide on the size and steepness of the skating ramp that you would like to build. For the materials, you will need pieces of exterior plywood, skateboard studs, pipes, lag screws and galvanized wood deck screws. Firstly, smooth out the surface of the sheets of plywood on one side.  With a sawsall, cut the curve or slope with the first four pieces of plywood. All four pieces should have the same degree of steepness and you will have to make sure that the cutting is smooth. You might want to use the first piece of plywood that you have cut out as a template and draw the exact slope on the 3 pieces of plywood before cutting them.

Secure a large piece of plywood in between two pieces of curved ones that you have worked on previously by nailing them with 3” screws. The dimension of the large piece of plywood depends on the size and width of your skating ramp plan. It should look like the frame of a halfpipe skating ramp. Cut out cross joists for your frame and start to screw them into outer layer of the frame by starting from the top of the curves. These cross joists will be supporting pieces of curved plywood later. For better support, you can create x-bracings with the remaining pieces of plywood and screw them underneath the ramp.

Take out the sheets of plywood for the ramp’s flooring and screw them onto the cross joists. Follow the curve of the frame and make sure that the smooth side of the plywood is facing up. Wet the unfinished side of the plywood as it will cause the plywood curl up a little. It will be easier for you to nail the plywood pieces to the joists to form the curve. The plywood for the flooring must be pre-measured so that it fits onto the frame perfectly. When you have completed securing the pieces of flooring, you are basically done.

Allow the skating ramp to dry up before applying finishing touches to it. You can paint it or put on double coatings of weather protection. Now, you already know how to build a halfpipe skating ramp!

How to Build a Paintball Gun

Monday, November 2nd, 2009

A paintball gun was originally used to mark trees and straying cattle. Now, however, it is an important piece of equipment in the game of paintball. For a paintball fanatic, constantly having to rent a paintball gun and related equipment can prove detrimental to the bank balance. Substantial savings can be made when one is in possession of instructions for how to build a paintball gun.

This project utilizes a quantity of PVC pipe. It should be noted here that all the PVC used in this project must have been pressure-tested, or else the user faces the risk of injury if the PVC ruptures.

First of all, two lengths of PVC pipe 1 inch in diameter measuring 12 inches long have to be cut out. Ensuring that the pieces are the exact same length makes it easier for them to be connected. Any exposed thread on the PVC pipes should be covered with plumber’s tape before you proceed.

One of the 12-inch PVC pipes is to have two 1-inch diameter PVC elbows attached to it at both ends. The joins must first be primed with PVC primer before the sections are connected with PVC cement. The two elbows should face in identical directions.

For the second piece of 12-inch PVC pipe whose ends have already been primed with the prerequisite PVC primer, two PVC T-s measuring 1-inch in diameter are attached with more PVC cement. Once the PVC cement has cured sufficiently for the pipes joined to the elbows and T-s respectively, the two pieces are connected T-end to elbow-end with PVC primer and cement in order to form a box shape.

In the next step of learning how to build a paintball gun, a 0.75-inch rubber nipple is attached to a 0.75-1 inch reducer that has been fastened to the open end of one of the PVC T-s. A 0.75-inch ball-valve is screwed to the nipple next. The barrel of the paintball gun, made from 1-inch PVC pipe in any desired length, although 3 feet is adequate, is in turn screwed to the ball valve. The tire valve is attached by drilling a hole in a 1-inch PVC end cap that is wide enough to fit the tire valve in. The tire valve is fit through the end cap and secured with glue.

While waiting for the end cap assembly to dry somewhat, cement a 9-inch length of 1-inch wide PVC pipe to an open end of one of the PVC T-s. Once that has dried, the end cap assembly is cemented to the end of the PVC pipe. The whole gun should be allowed to dry for up to 24 hours before being using, and a paintball gun should always be treated like an actual loaded gun.

How to Build a Pitching Mound

Monday, November 2nd, 2009

There are times where you have hectic schedules that you had to reject your boy’s invitation for a baseball match in the baseball court down town. Or did you just miss your son’s baseball match today because you totally forgot about it? You can make it up with him by learning how to build a pitching mound, and build one right in your own backyard. Your child will have the chance to practice on a pitching mound that has the same measurements with one he’s going to play on during the league. Furthermore, by owning your own pitching mound, you can practice throwing the mound with your son anytime when you are free.

Obtain the measurements of a live game’s pitching mound and build one accordingly. Normally, the diameter of it is 18 feet. Find a suitable spot in your backyard and make sure that the land is level. You will need materials like a rubber mat, sand, clay, and silt.

Pitching Mound How to Build a Pitching Mound

Draw the outline of the pitching mound. To build the pitching mound, you will need to put on inch-thick layers of sand mixture at a time. Mix an equal amount of sand and clay in a container before you divide the mixture into equal parts. Lay out the first layer of mixture on the outline and use a roller to press down the soil until it is firm. Place a stake at the front point of the outline and tie a string to it. Tie the other end of the string to another stake that is placed at the end point where it measures 17 inches from the front point. Add on another layer of soil mixture to the base and apply pressure so that the layers are flattened to 1 inch per layer.

Proceed to the next layer by moving the stake at the end point one inch to the middle. You will need to tamp the layers of mixture each time you lay them down.  Add on only one inch at a time until the pitching mound is 10 inches away from the ground.

For the final layer, measure 10 feet 6 inches from the front point and place a stake there. Then, measure 5 feet to the back of the mound and place another stake there. On the top layer, place four stakes to the left edge and another four stakes to the right edge. Lay out sand mixture of half an inch thick and use roller to press until the soil is firm. You should now have a plateau that is 10.5” from the ground with a width of 5’. In the centre point of the pitching mound, place a stake. Measure 2” from the front point and mark the point with another stake. Place the rubber mat 2” from the front point and roll it to the centre stake.

In a nutshell, this is fundamentally how to build a pitching mound.

How to Build a Putting Green

Monday, November 2nd, 2009

If you have a large backyard and you like playing golf, why not set up your own putting green so that you can practice golf whenever you want? Make putting green as part of your garden as these greens integrate well with the natural colors of gardens.  By practicing more, you get to improve your scores and eliminate handicap. Not sure how to build a putting green? Follow these steps and you can start practicing in your own backyard in no time!

Inspect your compound to see if the area has good drainage. A good putting green surface should be at least 1000 square feet. The area should also have full sun to ensure optimum growth of the greens, as well as good air flow. If your compound possess these natural advantages, it is suitable for you to build a putting green. Do consult professionals if you are not sure whether your compound is suitable to build putting green.

Putting Green How to Build a Putting Green

To build a putting green, you will need equipments and tools like a bobcat (hand digging tools if you do not have a bobcat), plastic pipes, irrigation tools, sand, seeds, peat, putting green cups and a cup cutter. You will need to spend a few hundred dollars for these materials but you get to save up a lot as professional planted putting greens will cost at least a few thousand dollars. Take the measurements of the area and go to a supplier for the materials.

Then, proceed to build the base of the putting green that consist of a bottom layer of dirt, a layer of crushed stones in the middle for proper drainage and a layer of sand (mixed with peat) on top. You can also use rich growing mixtures as a substitute to the sand and peat mixture. You can also plant irrigation channels to improve irrigation of the area. You will need half a pound of creeping bentgrass seeds for land of 1000 square feet. It can be purchased from local seed supplies. If you are living in warm locations, go for Bermuda grass.

Seed the entire area followed by watering the land and applying fertilizers. Affix the putting green cups with a cup cutter. Dig a hole that fits the cup and place the cup in the hole. For professional putting greens, the cup should be one inch below the grass. Generally, this is how to build a putting green but it requires a lot of time and care for these greens.

How to Build a Skateboard Ramp

Thursday, October 22nd, 2009

Building your own skateboard ramp means you won’t have any problem looking for a place to skate.

Required Materials

  • a piece of plywood 12mm thick and 600mm x 1200mm
  • a second plywood piece 6mm thick and 970mm x 600mm
  • 3 pieces of timber 45mm x 35mm x 576mm

Skateboard Ramp How to Build a Skateboard Ramp

Required Tools

  • drill
  • electric saw
  • glue
  • electric plane
  • screws and nails

Instructions

  • Cutting the Wood – Cut the 12mm plywood into two right-angled triangles of identical size. The triangle base will be 900mm and the height will be 300mm. These two triangles will form the sides of the ramp.
  • Creating the Frame – Take a piece of framing timber and shape it with a plane to give it the same angle as the top edge of the triangles. After this, rivet the piece of timber to both sides of the triangles one by one, ensuring that all edges are now flush. Now put another piece of timber at the lower right-angle edge and rivet it into place. The third piece of timber should be placed in the middle of the triangle and also firmly riveted into place. When riveting, initially use only one rivet. When you are sure that both pieces are flat and square, rivet them in more firmly into a permanent position.

  • Nailing it Down – Cut a piece of plywood from the leftover piece. Use an electric plane to contour one edge to a similar angle as the pointed end of the ramp. Glue this into the right spot and then nail it down firmly. The nails will hold the pieces in place while the glue is drying; you should not use rivets or screws as the plywood may split. The plywood should be placed above the frame and in line with the top and two sides.
