JustBill Posted December 10, 2011 Share Posted December 10, 2011 I was wondering if the same applies for scale time. For instance, How old would a 49 Merc. be in 1/25 years? Quote Link to comment Share on other sites More sharing options...
Dr. Cranky Posted December 10, 2011 Share Posted December 10, 2011 LOL! For a minute I thought you meant how fast would a 1/25th scale would have to go in order to travel 1 mile! I feel the math coming on again! HA! I know the train modelers are always synchronizing their trains to travel at the right scale speed.

JustBill Posted December 10, 2011 Author Share Posted December 10, 2011 LOL! Well Doc... you bring up a good point as well. So now now we're looking for time and speed!! How old is a 1/25 49 Merc? and How fast is 60mph in 1/25? Quote Link to comment Share on other sites More sharing options...
SuperStockAndy Posted December 10, 2011 Share Posted December 10, 2011 A couple years ago, I honestly wondered about scale time... Quote Link to comment Share on other sites More sharing options...
moparmagiclives Posted December 10, 2011 Share Posted December 10, 2011 Brand new, still in the package . On a side note how do you think the time invested and money invested scale out to the real thing? Quote Link to comment Share on other sites More sharing options...
Chuck Most Posted December 10, 2011 Share Posted December 10, 2011 I try not to worry about it much. I just figure if Chip Foose can rebuild a car bumper to bumper, rubber to roof in six days, I should be able to do the same in 1:25 in a similar time frame. Oddly... doesn't seem to always work that way. Quote Link to comment Share on other sites More sharing options...

Foxer Posted December 10, 2011 Share Posted December 10, 2011 Scale speed is figured the same as distance ... just divide by 25 for 1/25 for instance. As for time, I defer to our resident Physicist. Quote Link to comment Share on other sites More sharing options...

Mr. Moparman Posted December 10, 2011 Share Posted December 10, 2011 Hmm. So 75 mph in 1:25 would be 3 mph! Quote Link to comment Share on other sites More sharing options...
Darin Bastedo Posted December 10, 2011 Share Posted December 10, 2011 Didn't many of his "rebuilds" consist of custom paint and wheels? (Yeah, I'm not a big fan)... It was more than that, they would strip down the complete car, rebuild or replace anything damaged and at the same time perform sometimes elaborate custimising, and still have it all done in 7 days. If you have never worked on rebuilding a real vintage automobile you have no Idea how insane that time frame is. Quote Link to comment Share on other sites More sharing options...
Rob McKee Posted December 10, 2011 Share Posted December 10, 2011 LOL! For a minute I thought you meant how fast would a 1/25th scale would have to go in order to travel 1 mile! I feel the math coming on again! HA! I know the train modelers are always synchronizing their trains to travel at the right scale speed. Actually a lot of model railroaders use scale time as well. If they are trying to keep some kind of a time table to emulate operations this is the way to go. http://www.model-railroad-infoguy.com/fast-clock.html As for speed, I have N-scale trains and I just go by eye. Running full out would emulate a bullet train on steroids. Quote Link to comment Share on other sites More sharing options...
sjordan2 Posted December 10, 2011 Share Posted December 10, 2011 (edited) I'm no math whiz, but time would be the one constant that doesn't change by scale. Speed isn't the same as time, of course. Let's say you wanted to emulate the following in 1/25: Kitty O'Neil in 1977 recorded the quickest quarter mile elapsed time of 3.22 seconds at 396 mph. You'd set up a track that's 1/25 of a quarter mile. Then you'd try to control your model so it covers the distance in 3.22 seconds. What you'd see would be the scale equivalent of going 396 mph. I'll leave to someone else to dig up the measurements or a better way of doing it. Another way to measure would be to measure wheel rpms for 1/1 and 1/25. If the 1/1 has so many rpm at 60 mph, the 1/25 version should have the same (assuming it's reasonably accurate in scale).

timc Posted December 10, 2011 Share Posted December 10, 2011 Can someone tell me what 1/25 equvalent of 230 lbs in1-1 is. I'm sick of this weight complex i'm having. Quote Link to comment Share on other sites More sharing options...
FASTBACK340 Posted December 10, 2011 Share Posted December 10, 2011 (edited) Can someone tell me what 1/25 equvalent of 230 lbs in1-1 is. I'm sick of this weight complex i'm having. 9.2 lbs. :)FWIW: A 1/25th. scale weight of a 3,300lb. car would be 132lbs.

SuperStockAndy Posted December 10, 2011 Share Posted December 10, 2011 scale weight of a 3,300lb. car would be 132lbs. I made a topic regarding that subject, and I suggest not going in there unless you're really good at math I wish it was that easy to figure scale weight though...

Junkman Posted December 10, 2011 Share Posted December 10, 2011 230 lbs are 0.23552 ounces (6.62 metric grams) in 1:25. 3300 lbs are 0.2112 lbs (95.8 metric grams) in 1:25. 1 Second is 1 Second in 1:25 A car travelling at 60mph is travelling 2.4mph in 1:25 Quote Link to comment Share on other sites More sharing options...
Harry P. Posted December 10, 2011 Share Posted December 10, 2011 Ok, time is not scalable, it's a constant, right? So if a 1/1 car covers one mile in 60 seconds, it's traveling at 60 mph (a mile every minute). If a 1/25 car covers a "scale" mile (1/25th of a mile) in the same 60 seconds, it's covering 1/25 of a mile every minute, or a full mile in 25 minutes. So 60 mph in 1/25 scale is 2.4 mph? Right? Edit: Didn't see Junkman's post... he already covered it. Quote Link to comment Share on other sites More sharing options...

Alyn Posted December 11, 2011 Share Posted December 11, 2011 (edited) My turn 1 second in 1:1 = 1 second in 1:25 scale (time remains the same) 3300 lbs in 1:1 = .2122lbs or 3.38oz in 1:25 scale (weight is 3 dimensional, therefore *25 cubed) 60 MPH in 1:1 = 1,500 MPH in 1:25 scale (distance is 1 dimensional, therefore *25) Edited December 11, 2011 by Alyn Quote Link to comment Share on other sites More sharing options...

JustBill Posted December 11, 2011 Author Share Posted December 11, 2011 (edited) OK. I think my point got lost. Lets say you have a diorama. Take and put it on a automatic turn table with a set speed of how fast the earth is turning scaled down to 1/25. Wouldn't you get a few revolutions before a 1:1 day is out? I'm thinking there's twelve months in a year for us. So if you take 25 out of 1/25 and divide it by twelve you get a little over two years in scale to our one year. Does that sound about right? I'm thinking in terms of dog years. Edited December 11, 2011 by JustBill Quote Link to comment Share on other sites More sharing options...

"1 second in 1:1 = 1 second in 1:25 scale (time remains the same)" 1 minute = 1 minute 1 hour = 1 hour 1 day = 1 day 1 year = 1 year Quote Link to comment Share on other sites More sharing options...
