Spring Design and Manufacture for Home MachinistsThis book explains the properties for each type of spring, plus essential materials and methods. Few mechanical devices are entirely devoid of springs of one sort or another, but satisfactory operation rests on details such as spring strength and degree of movement.

This book explains the properties for each type of spring, plus essential materials and methods. Few mechanical devices are entirely devoid of springs of one sort or another, but satisfactory operation rests on details such as spring strength and degree of movement. Yet information on calculating and making springs is not easily available. Designing springs can be difficult due to the number of variables and the complexity of the formula. The book also introduces the designer to charts and nomograms, which greatly simplify the process. Topics include tension and compression spring principles, compression and spring design, examples for winding coil springs, how to design, make, and coil a leaf spring, torsion spring, and I.C. engine valve springs.Shipping Notes

Works better than expected.
Size: 1 count (Pack of 1)
I really wish this was, like, a gel for running or something because the flavor is really tasty. Not too sweet, but flavorful enough to make sure you use it. It's a nice orange flavor that doesn't taste medicinal. I applied to the front and back of my teeth only and it lasted half the night. Quickly applied more and it lasted the rest of the night. I'm probably applying way too little but I genuinely just tried it so I'm not used to it yet.

Picture is deceiving .
Size: 1 Count (Pack of 2)
Picture of XYigel is deceiving as it shows two boxes. As it turns out you only get one box with two tubes in box. Picture should be changed to show one box

Didn't like the taste

Exceptional dry mouth gel
Size: 1 count (Pack of 1)
This stuff for dry mouth is amazing. I love the taste and the coating it leaves is great until I eat and then reapply. Best product I have used although more expensive than I would like.
