I had to take the saddle tank off my Ida last week and the only tool I had that would fit the bolts was a pair of parallel jaw pliers. By the time I got it back on I was convinced that I would need a proper set of wrenches and nut drivers before my oversize cylinders arrived and I started to add details to the engine. I began a search and found a source of minature tools. I ended up buying a 6 piece inch nut driver set, a 9 piece inch open end wrench set, a 7 piece metric nut driver set, and a 9 piece metric open end wrench set. These are Moody tools which are made in the USA and have been around for 40 years that I am aware of. I probably didn't need the inch sizes but you just can't have too many tools. The cost was $53.83 for the tools and $5.05 for shipping, $58.88 total. I placed the order online Monday evening (5-3-10) and the tools were in my mailbox today (Thursday, 5-6-10). I am quite pleased with the tools and can't say enough + about the service from the dealer, Micro-Tools:
