Please show it on an 880!

I'll try to arrange that and post the outcome.

Hi, 

Well, it made me smile - I like it !

I expected a 1 pull wonder followed by endless resetting etc, etc, so I think that's quite an achievement to have created a thing which presumably keeps pulling until the user switches off the drill.

Operational concerns, 

- Mechanical reliability of the starter mechanism on the tool you're starting - I know some people just keep yanking on the cord but really the first stage of the pull should engage the starter pawIs before the real tug of war begins. And that's after you've found the correct starting point. 

- Structural reliability of what ever your starting device is pushing against,  you have to remember if a tool can be misused it certainly will be, I can imagine someone leaning it against a fuel tank ....

- Safety issue of the machine you're starting jumping about at start up, there's good reason every manufacture of chainsaws states the user must hold the saw firmly when starting. Starting on the floor requires foot through back handle and hand holding forward handle....

- User response time after engine start up is shockingly poor, you need to be able to operate the controls of the machine as soon as it fires up, crucial for a chainsaw.

 

Sorry, that seems quite negative, I think it's a great achievement to have got this far but equally I'm not convinced of its practicality in the world of chainsaws.

Many thanks for the detailed comment

Brilliant idea, good luck with it.

Wonder how it'll cope with a MS 200 with 6 inches of starter cord.   That's how most pro's use them, isn't it?

I could make one with a short pull. Or perhaps extend the cord on the saw.

I doubt pro contractors would find much use for it.

 

But large estates, older gardeners with multiple tools, golf courses and colleges might be the market place.

Very cleaver . Well done .

I would like to see it pull over the old McCulloch
