Return Board and Pimples

[tzifos]

A friend of mine has a return board for practice and the board has some generic rubbers on one side. He though that it would be a good idea to add some different rubbers, Pimple rubbers on the other side so he can work with top spins to long pimple rubbers. The question is this: Should he choose to glue long pimples with or without sponge ? OX or something like 0.5mm sponge?

hope this helps, this is my setup:

rb1 = generic rubbers from Chinesepingpong, e.g. Sanwei
rb2 = PVC desktop mat, has antispin effect, i.e. the best for generating 'underspin by the returnboard'

Something like this??? (ie from IKEA stores)

for rb2? yes. this is the exact mat which i had installed:

has zero friction, has a dampening effect (like a Butterfly dead rubber), is easily installed (double-sided tape) and tested, works great 👍
just in general, however, it's challenging to make any frictionless board produce a valid rebound, several conditions must be met (by the incoming ball), i wrote volumes about the topic on other forums.

i like my rb2. but since i got 2 robots, i retired the rb's for the time being. i can confirm that robot training is indeed so much better!

Are you suggesting that we can generate underspin on a returnboard? I thought returnboards are only useful for topspin rallies. If we use the said material, do you think I can push to the returnboard and it will come back as underspin or topspin?

You're asking long questions. The returnboard is placed at (not over/above) the table. One never pushes to it. One plays a topspin ball: rb1 would produce a ball which has no spin or minimal topspin coming towards you, whereas rb2 would produce a ball which has lots of underspin coming towards you: this ball you can push but neither rb1 nor rb2 will produce a valid rebound from your push.

In numbers, if you generate a topspin ball carrying 20rps (rounds per second), then you'll get a underspin ball back, from rb2, carrying the identical 20rps: the spin angular velocity vector remains constant\the same.

Since your post, I am intrigued to try desktop mat on the backhand side of my return board. Following your link, I see that the desktop mat you used is made of faux leather. Can you confirm if I can buy faux leather desktop mat or it has to be made of PVC?

Your question seems ill-posed, i caht confirm

My advice: order a PC desktop mat shipped from amazon (80x40cm), stick it to your wood board with carpet tape, test the anti-spin effect and rebound, and if it doesn't work for you, then return it to amazon for FREE and test another mat from amazon etc.
