An absolute neccessity if you are going to attempt an engine strip without risking damage to increasingly rare (& valuable) engine components.

For every correct way to accomplish a task, there will be a dozen ways a bodger could do it cheaper. Use the correct tools for the job and the chances of having an unpredictable event occuring are very, very slim to non-existant. But if you (or your engineer mate) bodges it and it goes wrong just how much will it eventually cost you? With parts harder to obtain and ever more expensive to buy, having one of these tools in your armoury will certainly pay dividends. Tools to trust - an investment for the future
