Discussion Overview

The discussion revolves around identifying and sourcing a mechanical component for a project that mimics the functionality of a rowing machine, specifically a retractable pull cord system that engages a spinning wheel. The inquiry includes both the mechanics involved and potential purchasing options for the necessary components.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Homework-related

Main Points Raised

  • One participant describes their project requirements and expresses uncertainty about the terminology and components needed.
  • Another participant suggests that a "Recoil Pull Starter" is the appropriate component for the described mechanism.
  • A participant seeks further clarification on additional components needed to engage the recoil pull starter, mentioning the possibility of needing an old lawnmower.
  • Another participant explains the necessity of a cup that attaches to the flywheel, detailing its construction and function in relation to the pull starter mechanism.
  • A later reply provides a specific search term for purchasing the recoil starter cup assembly and suggests it is a more economical option than buying a second-hand mower.

Areas of Agreement / Disagreement

Participants generally agree on the identification of the recoil pull starter as the relevant component, but there are varying suggestions regarding additional necessary parts and purchasing options. The discussion remains open with no consensus on the complete setup.

Contextual Notes

Participants have not fully explored the compatibility of the recoil pull starter with different wheel systems, and there may be assumptions about the mechanical setup that are not explicitly stated.

Who May Find This Useful

Individuals working on mechanical projects involving retractable cord systems, hobbyists interested in DIY mechanical assemblies, and those seeking to understand the components of recoil starters.

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.
Here is an example; https://www.ebay.com.au/itm/403241128796
