Slide Rule Basic Operations

 

 Never thought about how a slide rule worked cause I always had a calculator, but inherited a slide rule from my dad and then found a pamphlet on slide rules when cleaning out my father-in-laws work shop.

So I added learning how to use a slide rule to my list of things to do when I had more than 8% of my weekly hours free to investigate interesting interests.

 My slide rule has 6 scales, C, D, A, B, C1 and K. Scales B, C and C1 are located on the inner sliding section of the slide rule. I have not used C1 or K yet and may never. Slide rules also are supposed to have a third piece which provides a sliding section containing a hairline crossing perpendicular to all the scales. My slide rule was missing this and so I used a paper clip as a pointer. There are other variants of slide rules for different specific functions.

The scales have an index or starting point on both the Right Hand (RH) and Left Hand (LH) ends of the slide rule. If you can't find the answer, the other index is to be used.

Multiplication:

To Multiply 7 x 5, for example

1. The C scale(bottom scale of the internal sliding section) right hand index is first set to 7 on the D Scale (bottom scale on the base of the slide rule)
2. The hairline is set to 5 on the C scale.
3. The result of 35 is read off the D scale at the hairline.

There are explanations about logarithms as to how this all works, but to mechanically multiple, you don't need to know that.

 Division:

To divide 5 by 4,

1. Set the hairline to 5 on the D scale
2. Slide the C scale so 4 aligns with the hairline.
3. read the result of 1.25 at the C scale Left Hand Index
   

 

Finding Cubes:

 

To find the Cube of 20

1. Set the C scale Left Hand Index to 2 (20)
   
2. Set the hairline to 2 (20) on the B scale
3. Read 8 off the A scale
4. Adjust the number on the A scale to get 800
   

Finding Square of:

Finding Square Root of: 

1. To square a number, look at the number on the D scale and the corresponding number on the A scale using the missing hairline device. The number 3 points to 9, the number 5 points halfway between 2 and 3 which is interpreted as 25.
2. To get the square root is just the reverse.

 

 

 

2023 Maple Mead

Started on September 4, 2023 and racked to 5 bottles on September 25, 2023. Was happy with the amount of mead generated, a gallon is too much to drink and I don't know that many people to foist homemade mead upon. Only one review so far, expressed an opinion that it was stronger than the 2022 batch. It could be that the Mead is still too young.

September 4, 2023

Make 2/3 cup maple syrup from ½ cup water and 1 packed cup maple sugar.

2/3 cup maple syrup is equivalent to 5.3333333333 oz.

 

Original recipe was 2lbs honey and 12.5 oz of maple syrup, 1.6 g yeast and 0.5 g yeast enhancer.

Halved is 1lbs honey and 6 oz maple syrup.

 

Ingredients

·      1/2 Gal water, 8 cups

·      1 lbs Honey

·      3 oz maple syrup

·      60 grams maple sugar, about 1/3 cup, err on more?

·      0.8 grams Yeast, Mead M05 Mangrove Jack

·      0.25 gram Di-ammonium Phosphate, yeast enhancer

 

Equipment

·      1 gallon jug

·      Air lock

·      Long thermometer

·      1 cup measure

·      2 cup measure

·      Large metal pot to sanitize things in

·      Metal Pot to hold ½ gallon plus of water, 8 cups

·      Pot to mix honey, maple stuff and water

·      Funnel

·      Large Metal spoon

·      Metal skewer to stir in jug

 

Instructions

 

1.     Sanitize all your equipment using as per the instructions on the packet.
Note: Never use bleach! Bleach will react negatively with the fermentation process.

2.     Warm honey and maple container to make pouring easier.

3.     Put 4 cups of warm water in a pot, measure out about 2 lbs of honey and mix with the warm water in the pot.

4.     Mix the maple sugar in a measuring cup and dissolve.

5.     Mix in the maple syrup.

6.     Pour honey/maple/water mix into 1 gal jug.

7.     Add additional 4 cups of water to fill to just about half of the jug and stir/shake.

8.     Use a thermometer in your gallon jug. Continue when the temperature is between 65 and 85 degrees.

9.     Add your yeast enhancer stirring gently until dissolved.

10.  Pull out about 1 cup of must in a two cup measure and pour your yeast in and stir gently. Let it sit for about 15 minutes or so. When it starts to foam, gently pour back into the jug. Close jug and install airlock.

11.  The mead will start fermenting after a couple of hours. You will see the airlock start bubbling. Keep the jug in a place between 65 and 85 degrees and let the yeast do its work. This could take 10 to 20 days.

12.  When the air lock bubbling slows down dramatically, rack the mead into your bottles using the siphoning tube. Be careful not to siphon up the sediment on the bottom of the jug.

 

 

 

2022 Mead (Honey Wine)

Started first Batch of Retirement Mead on 10/30/2022, the Mead received adequate reviews from multiple parties. It was a bit harsh initially, but mellowed with time.
