Iv been reading lilja barrels and that will probable be the way i go so thank you for telling me about them . What is certs? May i see your 50 cal ? And i do kinda like holmes design but there are little things i dont that id like to change
Oh my god, if you don’t know what certs are you shouldn’t be making anything that goes boom.
Ok, so let’s get to the basics, certs is short for certifications. If you order a material, say 8630 chromium molybdenum low alloy steel, how do you know it is what you ordered, and actually chrome moly and not just cold rolled 1018?
Well, you simply don’t for sure without independent reliable verification, but one thing many do is ask for certs on the material from the supplier.
This MAY result in the supplier taking a bit more care in being sure the correct stock is pulled for your order, and it does cover your ass to some extent when and if you wind up in court after an accident or catastrophic failure, but it is absolutely NOT an assurance that the material meets specs and is high quality and free of serious defects.
That must be done by an independent Or in house (YOUR house) testing lab with audited and verifiable protocols and procedures.
If you are using a design with a substandard safety factor such as 1.2 there can’t be ANY major flaws defects or shortcomings in your materials.
Unless there is a compelling reason to do so and all precautions are taken, it’s just stupid to cut it that close.
