Factory style/original tools are now collector’s items and seldom become available. In any event, there were few of these tools at any time—only the dealers tended to purchase and use them. Some of the tools, like the ones needed to rebuild the brake servo units (power brake boosters) were never available. The factory workshop manual contained directions on how to make them if anyone ever needed them. Hence, factory tools are only obtained by chance and, often, at significant expense.
Over the years, I developed my own tooling to do a number of the jobs which require special tooling. Some of these tools are based on the factory designs and some are based on my own ideas. I have, for several years now, made them as gifts to various friends, some of whom are working, professional MG mechanics. The problem with making them to sell is that the volume of tooling required is low—there are not that many MGs left on the road and not everyone wants to work on their own cars. Hence, having tools made by CNC production, which results in significant cost savings on large volumes, is not an option. Small volume production runs on manual machines is the only practical method, but, there is a drawback. It takes a long time to make a single tool, far more time than the tool can be sold for. Most tools take more than one hour of man/machine time to make. Thus, the cost of the least expensive tool becomes prohibitive—few people would pay the $65 per hour man/machine rate to own a tool that will be used only once or twice.
