Mvd inverted roller head G3
So im ready to pull the trigger on one of these but im seeing a potential problem in the design. Maybe it works, im not sure.
From what i know, a roller is supposed to have wishbone stoppers to give the spear a smooth exit. The G2 model has those stoppers but they got rid of them on the G3. Won't the wishbone tip the back of the spear? Can someone more knowledgeable or the roller guys enlighten me on this? G2 and G3 pictured... Sent from my BLU DASH M using Tapatalk

Re: Mvd inverted roller head G3
With the G3 you would tie stopper knots at either side of the end of the wishbone. The stopper knots would hit that bar at the end in front of the rollers and leave a small loop loose, allowing the shaft to pass smoothly. This system actually works quite a bit better than the raised stopper that the wishbone pulls taut against. I’ll find a picture to show you what I mean as it sounds a lot more complicated than it is.

Re: Mvd inverted roller head G3
Nice... I thought id never get a response... Its funny how i considered that method but assumed that knots wouldn't be practical as they would probably pull through or get stuck...
Man thanks a lot as i really don't like the look of the G2. As they say a picture is worth a thousand words... Sent from my BLU DASH M using Tapatalk

Re: Mvd inverted roller head G3
Not to open back an old thread, but you guys were talking about just what I had questions about.
I was wondering if any of you could help me out on that knot tying process for the wishbone to pulley string connection. How do I do this? And should there be slack in the primary band or should it be tight against the rod in front of the rollers? Anyone have experience with the Ermes sub testata inverted roller head? I like the way it looks and how the band string/wishbone would stop againstthe raised stopper. Anything helps, thanks |
