The Bonney RC-162 stones are a must-have accessory for RC-160 and RC-170 engine builders seeking optimal engine performance. These stones are specifically designed by Bonney Forge, a renowned manufacturer of high-quality engine rebuilding tools, to cater to the unique requirements of RC-160 and RC-170 engines.
The RC-162 stones set includes six individual stones of various grits, providing an extensive range for honing engine components to the desired level of precision. The set includes:
1. Two 320 grit stones: Ideal for initial engine boring and roughing out the cylinder walls. This grit size effectively removes excess metal and prepares the surface for finer honing.
2. Two 400 grit stones: Designed for medium-grade honing, these stones refine the cylinder walls, removing any remaining rough spots and minor scratches.
3. Two 600 grit stones: The finest grit stones in the set, these are used for final honing and polishing. They leave the cylinder walls with a smooth, mirror-like finish, contributing to improved engine efficiency and longevity.
Each stone measures 11 inches long by 3 inches wide and 1 inch thick, ensuring a perfect fit for the RC-160 and RC-170 engines. They are made of aluminum oxide, a durable and effective abrasive material that guarantees long-lasting performance. The stones are also flat-bottomed and come with a uniformly ground surface, ensuring consistent honing results.
To use the stones, simply soak them in water for approximately 15 to 30 minutes before honing. Apply a thin layer of honing compound and hone the engine components according to the recommended procedure. After honing, clean the stones thoroughly with water and a soft-bristled brush to maintain their optimal performance.
Investing in the Bonney RC-162 stones for your RC-160 or RC-170 engine honing project not only ensures a perfect cylinder bore finish but also guarantees improved engine performance and longevity. These high-quality stones are an essential investment for any RC engine builder looking to achieve the best possible results.
The RC-162 stones, although primarily designed for the RC-162 honing machine, can also be used with the RC-160 and RC-170 models with some adaptions. In this analysis, we will discuss the potential advantages and disadvantages of using RC-162 stones for honing these machines.
Pros:1. Superior Finish: RC-162 stones are known for their ability to produce a superior finish, making them an excellent choice for those seeking a high-polish, smooth running engine.
2. Versatility: RC-162 stones can be used for both engine and crankshaft honing, providing an all-in-one solution for various honing needs.
3. Longer Stone Life: Due to their larger size, RC-162 stones may last longer than the standard RC-160 and RC-170 stones, resulting in fewer stone replacements and cost savings over time.
4. Consistent Honing Results: The larger stones provide more stability and consistency during the honing process, ensuring a uniform finish and improved engine performance.
Cons:1. Compatibility Issues: To use RC-162 stones with RC-160 and RC-170 machines, additional adapters and modifications may be required, which could add to the cost and complexity of the setup.
2. Increased Weight: The larger size of RC-162 stones makes them heavier than the standard stones, which can be more challenging to handle and maneuver during the honing process.
3. Higher Initial Cost: RC-162 stones are generally more expensive than their smaller counterparts, making them a more significant investment for hone owners.
Conclusion:Using Bonney RC-162 stones for RC-160 and RC-170 hones offers several advantages, such as superior finish, versatility, longer stone life, and consistent honing results. However, there are also disadvantages, including compatibility issues, increased weight, and higher initial cost. The decision to use RC-162 stones ultimately depends on the user's honing needs, budget, and willingness to invest in additional adapters and modifications.
Recommendation:If you prioritize a high-quality finish, consistent honing results, and are willing to invest in the necessary adapters and modifications, using Bonney RC-162 stones for your RC-160 or RC-170 hone may be a worthwhile investment. However, if you're looking for a more budget-friendly and straightforward solution, sticking with the standard RC-160 or RC-170 stones is recommended.
