Youth Engineering/Escort MP5 Upgrades

I've put up a temp table of prices for the parts which are going to be available this month. I'll be putting up full descriptions and pictures once they arrive in stock.

*Parkoluberised 203M07 Steel parts will be available once they pass inspections.

Escort Component Material Descriptions

1: Standard CZ108 Hard Brass. A high grade material and much stronger than normal CZ121 or CZ103 found in the standard Escort system.

2: 316 S31 Marine Grade Stainless Steel. Extremely high grade material typically used in submarine component manufacture.Very expensive to purchase and hard to machine on low powered machinery. Exceptional resistance to both wear and corrosion are some of the good points but notable for it's difficulty to process cheaply in small numbers.

3: 203M07 Leaded Steel Parkolubrised. The poor mans version of Hardstar treatment. Parcolubrise is a process often used in the manufacture of piston rings for cars where some degree of oil is required to stay on the rings to prevent dry startup or oil starvation at start up in the internal combustion engine. Commonly referred to as "Parco" it should not be confused with "Parkerising" that is a simple surface coating used to prevent corrosion.It gives good oil retention but is not as effective as Hardstar treatments however it is significantly cheaper to do although it is only available for use on certain steels where-as Hardstar can be applied to numerous base metals.

4: CZ 108 Hardstar Treated Brass. Hardstar treatment involves the flash heating of the material to high temperature to remove superficial alloying elements and oxidants followed by immersion in a silicon based lubricant (dry) at some 60,000 PSI of pressure inside a small pressure vessel. This allows penetration of the surface of the material and replacement of some of the materials structure on the surface with lubricant. Although the part will still require lubrication at set intervals this process does indeed make it less subject to wear and increases the materials ability to hold lubricants for much longer periods. Typically used on high pressure plain bearings this often removes the need to change over to roller or ball bearings to achieve higher surface speeds in rotating shafts. Components treated in this manner will often feel "greasy" or "slippery" even after drying with a paper towel.
