I am interested in building or having an sbr built, but I don't know much about the paperwork process. I did a half assed search but didn't find what I was looking for. I was hoping someone could give me a step by step on acquiring a stamp.
Oh....and welcome to the forum.
(hope you'll pardon the inside joke....DD214 and jpkmd will be here shortly to berate me, I'm sure.)
Sorry folks, but I have to ask...what are SBR's amd SBS's?
The influence of the elastomer such as SBS and SBR and their mixtures on the structure and rheological properties of blown bitumen B 65 blends, was studied. The crude oil denoted as SEB (Soviet Export Blend) was used to obtain the B 65 sample. Ten PMB samples were produced by modifying the bitumen with the so called polyfunctional additives (PA) which were produced by mixing SBR- and SBS-elastomer and 25/75, 50/50 and 75/25 SBR/SBS mixtures with a fatty acid distillation residue. PA contents in PMB amounted to either 3 or 5 wt %. The PMB samples were obtained by a simple stirring operation (a usual stirrer with 300 r.p.m. and represented the stable homogeneous mixtures. Some standardized examinations and the determination of the dynamic mechanical properties were used for the characterization of the PMB samples. SBR-elastomer lowered the Fraass breaking point slightly more than SBS-elastomer. In PMB samples which contained more SBS- than SBR-elastomer the softening point increase was the main cause for the broader interval of plasticity. If SBR-elastomer prevailed, Fraass point decrease contributed more to the greater broadness of the interval of plasticity. SBS-elastomer caused a higher increase of the softening point than SBR-elastomer. The elastic recovery measurements showed that even 5 wt % of SBR-elastomer in PMB was not enough to reach the 50 % value. This important demand could be satisfied only if the elastomer part of PA contained 50 % or more of SBS-elastomer. The master curves of the dynamic viscosity or the storage shear modulus versus reduced frequency were used to examine the influence of the SBR/SBS ratio in PMB samples on their viscoelastic parameters. The zero shear storage modulus G'[o], value of G' at 20 and 60 °C, the glass transition temperature as a loss modulus peak temperature (G peak) and the inflection point of turndown ofthe modulus G'at the glass transition region, as well as the flow activation energies and viscosities were determined. Compared to SBR-elastomer SBS-elastomer caused a greater increase ofviscosity and flow activation energies. The presented results showed that a balanced improvement in both the low-and high-temperature thermomechanical properties of PMB was attainable by addition of mixtures of SBS- and SBR-elastomer.Sorry folks, but I have to ask...what are SBR's amd SBS's?

Welcome to the forum 8M3.
<lol> Norton, we need a new stat for the forum, one that allows us to track who is the first to officially greet a new member, a title that is proudly displayed on the Home Page.
DD214, any thoughts on how we could do this?
Is there an option/check box (one use only) that can be added to a first users post in the new posters forum that is visible to people.....first to do their best "Norton" impersonation toggles the radio button and it gets tallied?
Right on cue.....
Can a non FFL joe blow manufacture his own suppressors/silencers as long as they're registered and taxed in the same manner described for the SBR? I'm not talking about selling them, mostly just for personal use.
Thanks novus, you're a knowledgeable dude. I appreciate you spending the time to share what you know.
You asked for it you got itPics would be great too, thanks.
