Ok...eval time on the Berlin epee point. Parts: Wire cup is a French style, so LP, Sport 7, or any common non-German wire will work. Was told by the vendor I bought it from that you could use a German if you snipped off the volcano tip. Overall weight of the point is 8 grams....comparable to a traditional FWF point. Weight spring: ARGH! I was taking the parts apart to wire it up and the spring went missing! Fortunately, I was able to take the exploded picture posted elsewhere, scale it up until the barrel on the pic was the same length as the real thing, and use the pic of the weight spring as a model to cut a German one down. Worked fine, although I needed to make sure the cut end of the spring sat against the wire block. Spacer and interior brass collar: I had some doubts as to the wisdom of this part of the design, as the spacer is the part pushing the weight spring down, but it worked out well. The end with the smaller hole goes against the spring, and it’s there to let the actual contact probe through to hit the wire contacts. The interior brass collar was there to stabilize the assembly...probably serves to support the plastic a bit as well. I can see nothing to indicate it has any other function. Washer: Lost it with the spring, but I ended up not needing it. If necessary, it would go into the spacer to put the tip a liiiillltle bit further away, effectively lengthening the contact stroke. Tip: Interesting design. What looks like a foil tip flange – where the spring would sit – actually looks a little larger inside, allowing the contact probe to project through when the tip is depressed. The small spring inside is merely a shock absorber. It is, therefore, NOT screwed to a post as Brtech thought. It looks like the small spring is glued to the back side of the flange to hold it together. Might be the same on the other side of spring as well. Tip at rest....you can see the contact probe deep inside the flange Tip pushed in to show the contact probe extendign out. The collar on the tip used a 7mm wrench...an 8mm would be too big. Standard 6mm flats on the bottom of the barrel. No problems wiring it up, although after losing the spring and washer I was a LOT more careful with the parts until I had the tip in. Given that the contact probe is solid, it’s very important to level the wire contacts...even more so than with a traditional tip, as the probe can’t move around like a spring can. Once it was installed, and the weapon assembled – now came testing. I opted for the most basic and easy to perform test....hitting the wall – a LOT -- and seeing how the sripside tests went. Sit down....hit the target wall 25 times right handed, then go left (french grip) and repeat....that way I got lots of different angles...especially left handed. Checked periodically....passes all tests....keep hitting. Lather, rinse, repeat. How many times? I counted....1000 hits...all of them solid ones wit the meter firing every time, as it was plugged into my Danbox. At the end of that, it STILL passed weight and both shims! The 1.5mm got a touch tight after hit 500 or so, but still well within passing, and inserting the gauge seemed to push it back up into proper position. The .5 was even better. I have a Negrini fan gauge, with feelers from 0.25mm to 0.6mm....it passed every one. Some damn fine engineering there....works as advertised. Will I carry it? Probably not....the cost is very high, and the parts are not compatible with more traditional points, so I’d probably have issues supporting it. It's also a bit complicated with easy to lose parts, and with no instructions on how to put it together. I was able to figure it out -- the exploded pic was a great help there -- but others might not be able to. If it was for my OWN weapons, tho?? Probably.
