Component Name and Where to Purchase?

[Cardan]

TL;DR

Searching for components that create similar actions to a rowing machine.

Noob to anything mechanical.
Working on a project that requires the same mechanics of a rowing machine (I think)- whereas I need a retractable pull cord that will spin a wheel. The cord will retract as the wheel keeps spinning. Pulling on the cord again will engage the wheel (even while its moving) and spin the wheel again. I have no clue what this system is called or even if you can purchase it. I've looked at rowing machine schematics but have not been able to determine what exactly I need. Also, where can someone purchase something like this? Thank you in advance

Welcome to PF.
You need a "Recoil Pull Starter".

Thank you! I'm researching this component now. Is there a specific wheel/attachment/system that I need to research that is necessary to engage a recoil pull starter? My research so far is telling me I need to buy an old lawnmower! Thanks again.

There is a cup that either bolts to the flywheel, or is cast as part of the flywheel. You will need to attach one to the wheel you will spin.
That cup has a hard plastic lining, usually Nylon, gripped by the pawls that extend from the pull start drum.

I'll start looking a little closer to that setup. Thank you for pointing me in the right direction!

Search 'Recoil Starter Cup Assembly' to get the new cup and mechanism for $15 including postage. Cheaper than a second hand mower.
