Can someone please tell me what the diameter of a circle of this track would be? I have 24" deep benchwork, would it fit?
This is a Peco ST-412 HOn30 Setrack Curved Track. #1 9 22.8cm Radius, 45 Degree Sections, Double Sections pkg(4)
24 inches equal 61cm. A 22.8cm radius curve has a diameter of 45.6cm, measured from track center to track center. Add about 3cm to each side and you have an outside diameter of 51.6cm, leaving you with 4.7cm on each side of the curve. That´s sufficient!
Thank you Ulrich! The metric system threw me off.
I grew up with it, so it is a no-brainer for me. OTOH, I find it difficult to get by with the measurements you folks in the US use, especially when talking about weight and liquids.
Ulrich, the good news is your petrol is less expensive. When ours is $4, yours is usually about $2. What a deal! Of course, we get a bit more. [:D]
3.785411784 times as much, to be precise!
Will the US ever adopt the international metric standards? I have my doubts, despite all the talk about globalization and “free” trade.
Ulrich,That’s all Geek [8-|] Speak or maybe more like Algebra to me because I’ve dealt with inches and feet all my life.[:O]
I never could understand all that cm stuff.[:^)]
When I worked in the Middle East, I had to do a lot of conversions. I think of it as grocery store metrics:
One kilogram = 2 pounds
1 liter = 1 quart
1 kilometer = 0.6 mile
2.5 centimeters = 1 inch
Not exact, but close enough to buy the correct amount of meat and cheese at the deli counter. Temperature conversion is another thing; why Farinhight choose the feezing point of Baltic Sea water for zero degrees has no logic, except that he was a sea captain who had ships in that body of water - no quick estimates for that one!
You made him British [swg],
Daniel Gabriel Fahrenheit was born in Danzig/Germany on May 24th, 1688, son of Daniel and Concordia Fahrenheit.
I worked for a State highway department Enroachment Permit branch during the changeover to metric. The State made the conversion more compliated by trying to make it easier. There were “soft conversions” (approximate) of English system measurements to Metric system measurements and “hard conversions” (accurate).
Part of my job was entiering the Post Kilometer (PK) of existing Encroachments into the Permit data base. This was the relatively easy part. I knew to use hard conversions.
I also wrote Permits for new, modified and relocated non-State features being done as part of Highway projects. Durning the design process the Right of Way branch coordinated with Design and negotiated with the Encroachment owners. They would then send the location information PK to me to write the Permit. Unfortunately they usually sent me soft conversion PK’s which were usually way off the actual location. They were not engineers, were often working from existing information especially early in the process, and most didn’t understand the need for accuracy.
I worked with project plans (usually incomplete), existing plans (English system) and the info sent from R/W to determine the correct PK’s and still sometimes goofed.
With a base of over 100 years of non-metric plans and data there were also blunders made by the designers.
Ulrich, the answer to adoption of the metric system is no. Years ago some of the engineering societies insisted that text books use the metric system. It was an absolute failure.
My question was one of those that don´t require an answer. I am absolutely aware of the reluctancy to abolish the rather medieval system and adopt the metric system as it is used by the rest of the world.
The OP’s question has been answered. Let’s move along now.
