I’ve recently been working on a project that required me to use my micro screwdriver set. A common problem with this set was the inability to generate enough torque to remove the screws by hand. As a result I would often use a pair of pliers to generate more torque, occasionally damaging the screw head or over tightening them.
From a past instructable that I’ve read involving Oogoo, I’ve combined it with a new idea to resolve my issue. The solution is to make a new rubber handle over the existing one, moulded from a previously made product.
Step 1: Equipment Selection
1. Select the screwdriver you want to upgrade.
2. Find a decent feeling screwdriver or handle from any tool to mould.
Step 2: Bottom Mould
1. Create a container for the mould housing.
2. Use clay to fill the bottom half of the mould housing.
3. Press the handle into the clay and tape the mould housing together, making sure to prevent any leaks.
4. Mould the handle using plaster of Paris (a ratio of 2:1, plaster to water).
5. Pour the plaster in the mould housing and wait until it sets.
Step 3: Top Mould
1. Remove the handle and cured plaster from the mould housing and the clay.
2. Invert the mould and place it back into the mould housing with the handle.
3. Lubricate the bottom plaster mould with oil (I used car oil).
4. Pour in the top half of the mould with plaster and let cure.
5. Once set, separate the plasters from the handle.
