Have some times this week to continue working on my rowing machine. First is the basket used to contain weights (just some bricks instead of those iron weight plates). It runs on 4 small plastic wheels lying on 2 wooden rails. A system of line and 3 blocks is used to move the weights basket sliding up and down in an near – vertical manner (75 degrees).
It’s only when I first try running the machine that I’ve found out it is making so much noises, the 8 wheels on wooden rails. I decided to change from the slanted design (4th image) to an upright one (5th image). The weights would run up and down by a system of lines and pulleys, rather than running on rails. Proceed slowly as I have little free time for the moment.
