TTI Pistion for Diana34

We have this time produced something different that what is commonly available in the market. After lot of R&D we finally comeup with an interesting design that works perfectly with Diana 34 T06 (T05 will be also available with same design).

TTI Piston is on the left hand side and the OEM piston is on the right.

As you see the TTI Piston is not having any SLOT. Yes you saw it right, this is the idea. Without the slot, it will fit and function perfectly as expected and also it helps to reduce noise that produced by the spring vibration.

The groove in the back side of the piston is meant for Plastic ring for friction less operation. The entire piston is Hardened.

Diana 34-t06-Tuning-Part-2

Found some good quality grinding stone fitted with my drill machine.

P1030062About 5 mins carefully holding the cocking arm on the stone.

P1030064The radius started taking the shape.

P1030065Looks good!

P1030071Ahh!! lovely!. This is what we were expecting to get.

P1030077Holding the piston very well to do a perfect sliding job.

P1030086Another view more more understanding.

P1030078Inside the piston there is no sign of extra material of cocking shoe. ūüôā

This TTI piston is not having any SLOT and it works flawlessly in this airgun.

We did some shooting with this TTI piston and we are extremely happy with the performance. We have’t apply any TAR on spring while testing and found this gun to be a very well behaved one.

You must follow this before buying Diana34 TTI piston from us.

We are trying to make Diana 34 from good to an excellent.

So lets find the improvement areas.

P1030039To the above picture, we want you to understand and watch it closely as this cocking shoe pays a vital role for smooth cocking. This is the reason why Weihrauch or AirArm makes separate cocking shoe for their airguns.


In this picture, this curve looks to be better and we’ll see series of picture where we’ll understand the improvement that can be done.


In this picture, we can see the there is some noticeable sharpness which could be a reason for problem.

P1030055-copyHere you can see the cocking shoe not seating on the piston properly and the edges of the cocking shoe is clearly not allowing it to seat properly.


P1030060-CopyA much better picture to understand that.

Next part, we’ll grind the extra part in order to make the cocking shoe seat properly.

By doing that, we’ll get two benefit.

1) while cocking, the cocking shoe can seat properly on the Spring’s outer diameter therefore you will get less friction and sound while cocking the gun.

2) If you insert any shim inside the piston, there is a less chance that the shim cuts off over the time.
