There are four clear periscopes with PE mounts (again - kinda wish there was a platic alternative, since I'm not convinced the PE has a really strong bond...) Also got the fighting compartment finished up. Here it is with the three major components dry-fitted: I had to give a lot ...
Some solder will contain a small amount of silver. This pushes the melting temperature up a bit, but the silver helps the solder to flow and makes a stronger joint. If you are worried about burning whatever your working with, try to stay away from solder with silver in it, but it works...
The kitchen is the place to clean fish and make strong coffee. It may be outfitted with vintage utensils like graniteware kettles and cast-iron skillets for frying up the day's catch. The Contemporary Cabin While many log cabin styles glory in the patina of age, modern and contemporary ...
metallurgy, design, and (only rarely) the dates on them. Up until the 18th Century, the stems and bowls were made separately, and then joined together – usually with a solder. Starting in the 18th Century and ever since, spoons have been stamped from...
Wetting is the adhesive force between the molten solder and solid copper wire that causes the molten solder drop to spread-out across the surface to form strong electrical joint. Cohesive force on the other hand causes the formation of solder balls and hinders the contact with metal/copper surfa...
. You also need to make up some sort of jig to accurately (and repeatedly in the case of multiple boards) locate the stencil on the PCB. The great thing is that you get the perfect amount of solder (assuming of course the stencil is designed correctly). Here is aSparkfun tutorialon ...
How long it's plated, how much solution is used, and how strong the current is, determine the thickness of the copper. Changing these things can create PCBs with different amounts of copper. Cost: Copper costs a lot, and using more of it makes things more expensive. So, when making a...
The lower, or auxiliary mirror, is plain and is tilted slightly upwards ; it reflects light from the same source on to a small scale. The whole is suspended by a robust phosphor bronze strip (4) so that the coil lies between the curved pole faces of a strong permanent magnet (5) and...
5) Visually inspect where the wires are soldered to the coil. It is not unusual to see many of the wire strands broken off. The more that are broken off, the higher the resistance which will reduce flipper power. 6) It could be the power supply to the flipper. Check for burnt connec...
