Do you happen to have any interests with activities inside a workshop? Splurging money on a power tool is definitely not easy, especially with a power grinder that can cost a lot money. Mostly, power grinders are used for the purposes of cutting, grinding, and intense polishing on materials.
Power grinders can also be referred to as angle grinders. This equipment is powered mostly by petrol (gasoline) and electricity, and since electricity are costly in some place; this may be a problem for aspiring mechanics. What would be the best solution for this? A manual and homemade power grinder!
Making homemade angle grinders are better than acquiring angle grinders from stores. If you have the abilities to do so, then it is better to make it than to splurge excessively on it. Few scraps of metal, gears, and even old bike sprockets can be useful.
