Hi, this is my first post on this forum, so forgive me if this is posted in the wrong section.
I made a RSVP MMX, and made it such that the COG is the COP, and I put one signo tip in the RSVP cap and i put one signo tip and one hgg tip at the other end to balance it out. Although the COG is now the COP, the feel of the pen feels weird, as the RSVP cap is close to the COP, so this makes performing some tricks awkward. Do any of you have any suggestions as to where to shift the COG of the pen etc.
Thanks -

Hello, and a wonderfull (whatever daytime you might be reading this....)
At First, Hello and welcome to this board.
Second: Unto ya questian!
I do not know, if your explnations were a little misplaced, or a little misunderstandable.
I took a few pens and tried what you have done, and came to the following problems.
1)
If you take a normal RSVP MX, the RSVP Grip goes into the RSVP Cap, and an HGG-tip is screwed onto the Plastic RSVP tip, adterwards an HGG Grip replaces the aforementioned RSVP-grip.
These Pens are good-looking, but more balanced to the capped side, the back of the pen.
You can find inserts for these pens, showing off the center of Gravity (COG), in the "Show off your inserts" threads in the "Pen Modifications" Subforum.
2)
If I take two Signo tips, one to the front and one in the cap, preferably behind the RSVP's original grip, it adds the same amount of weight on both sides.
Means, the COG, the center of Gravity, ist still the same it has been before.....and this COG. center of Gravity, is by far not the COP. the center of pen / Middle of the pen.
3)
So, when checking ot the ring of the Cap, means up to which part of the RSVP barrel the cap mounts, it is around 5 to 7 mm behind the black RSVP cap and thus 3,5 cm /35 mm from the center of the pen away.
If it is weighted like you say, like a normal MX; sure, this is closer to the cap. But then, the pen is not balanced with COG at COP.
So, if this is possible, take an Pentel K176 tip and a Pilot G2 grip, then the RSVP MX Subversion has the COG at COP (mine has), or built an RSVP MX^2, you can find Teks tutorial in the "Pen Modifications" Subforum.
I do not have any other ideas or suggestions at the time be, please excuse me.
Sincerely

Thanks for the reply, I really appreciate it
As for your point 2), I put one HGG tip + one signo tip at the other tip of the pen, not just one signo tip, and another signo tip in the RSVP cap. And somehow, it seems balanced. IDK, i must have done something wrong if you say its balanced with just 1 signo tip at the front and one at the back.

Hurhur. Anyways, i think the imbalance was due to the g2 grip i had put on, so I tied a rubberband to the inktube at the cap side to balance it out, and it spins fine now.
