Seems I ran into someone at a steamup who had a very small crescent wrench described as "very hard to find" item. Thanks. The Channel Lock pliers were given to me by John Wieland and the crescent wrench is a novelty item in the basket at the check out count at Harbor Freight. I also seem to recall that Sears has them as well. I would guess a large tool dealer has the small Channel lock pliers. No you can't have mine. Clark

Hi Clark & Steve, Clark's recommendations are all top shelf! The only thing I would add to his list is a set of really good tweezers! Penn- Tool in Maplewood , NJ as well as MSC and other Industrial suppliers, will have most of the tools Clark mentions. Penn also carries the full line of Swiss DuMont tweezers, as used by Watchmakers, surgeons etc. they are non- magnetic stainless steel, and come with points from rugged, to so fine you need a magifier to see them! The small ignition size wrenches are also available from S-K (the makers) and I got mine through MSC in New York. Another too I found indispensable, when asembling an Aster kit, is a big magnet! (or a wife with really good eyesight and thin slender fingers!) as those teeny weeny little fasteners have a habit of jumping up off the work bench of their own volition, and scattering all over the floor! My wife and I spent an amazing amount of time on the floor, with a strong light and a magnet fishing for tiny nuts and bolts! Keith Taylor

Re: Metric or standard?
I use Sears automotive ignition wrenches which are available in two different sets. SAE and Metric. Each set has 10 wrenches which are open end on one end and box on the other. I use the metric nut drivers that Micro Mark sells, the Wiha brand. For BA I use the ones sold by Sulphur Springs Steam Models. I have both Aster and British engines. For screwdrivers I use the Wiha brand also. Expensive but tough. I also have a small (3 inches long) Channel Lock pliers and a small (3 inch long) Cresent Wrench. I find I use the Channel Locks in the field but not at the bench where I usually have the correct wrench at hand. Another handy item is hemostats in various lengths and curvatures. Absolutely needed when you have to hold a small nut way down inside something. -- Cheers Clark Clark B Lord - Las Vegas, Nevada USA Las Vegas Live Steamers - Gauge 1 live steam steve speck wrote: Thanks Jim, yes it is a Aster Mikado.

I think Roundhouse use 2, 4, 6, and 8, all standard BA sizes. I think their fillers, safety valves etc are another slightly odd English series the "Model Engineer" series. These are an imperial size series either 32 tpi or 40 tpi.
