This was another differentiated test with recycled material, where I was happy to find a cylinder plus the piston with a perfect seal, rather than ordering.
The cylinder is a test tube donated by Nélio and a small pump tube used by people with asthma. I really have to admit, that I was very lucky to find two pieces with such precision as well as perfection with quality.
Positive points of this new piston:
- it is a super light piston, prevents vibration, improving speed;
- did not require lubrication, only a polishing with liquid silicone;
- low friction in addition to an acceptable seal;
- durability;
Negative points;
- for this project, there is a need for a piston of larger diameter, to obtain greater compression and thus reach a new record;
The inside diameter of the test tube is 22.24 mm, and the outside diameter of the tube is 24.57 mm.
The piston outside diameter is 22.14 mm.
I apologize for my absence, due to my many private tasks, it is consuming all my free time, limiting videos frequently, but better times will come!
