The Happy Clapper

**watson** · 12th August 2009, 10:31 PM

G'day all,
When I turned fifty ( a few years ago) I was given a little kit to make up called "The Happy Clapper".
It was a hoot, but its now a few years old, but still works, and I thought it might be just the bees' knees for woodies to make as presents. My Happy Clapper sits on a shelf in the workshop, and when the sun came out today, I took three pics of it to show.
The upshoot of the post is that I'm going to make a new Happy Clapper out of better wood, and as I measure and plan, I was wondering if a set of plans would be helpful here.
So here are a few hurried pics of the Happy Clapper.

Ripper idea my dear Watson!

What a great present, I dare say from a great present giverer. There's some great mechanical toys about but it's the old ones and those made from scrap materials that do it for me, the more happly niave the better in most cases, just like Happy Clapper. I couldn't help, hope you don't mind, dusting off Pedal Man who like Happy Clapper sits on a shelf in my workshop and who always brings a smile.

Sets of plans are always welcome Watson. I know I'd like a set to make a Happy Clapper if you can please?

Workin' on it Buzza......trying to get around the faults in the original at the moment.
Won't be long though.

Yeah me too please, for more clarity. I suppose it's a cam that drives the rod up but it's not clear in the pic, niether is how or where it ends but maybe it's just fridee night vision

Its probably my pic taking. I'll get to it over the weekend.

awesome m8 thx for the share

Ok I've attached a set of rough plans as a PDF file.
This is as the toy exists at the moment, and I would make a few amendments to these for stability.
I intend using tooth-pick dowels at several points ( nominal 2.5mm dia ) such as :

Fixing the cam to the main shaft
Fixing the Arms and yokes to their shafts
Fixing the crank to the main shaft

and I would place a shaft flange at the rear of the body on each of the Arm shafts.

Have a look, and any amendments are all up to you. I think all the required measurements are in the drawings.

Have Fun!

Thanks Noel,You have done a great job there

Will be a few of these made

**wheelinround** · 15th August 2009, 07:27 PM

Noel thanks for that well done in the draughting

**springwater** · 15th August 2009, 09:00 PM

Thanks a lot Noel

between your pictures and plan even I should be able to manage making one, which I will one day, although it's very tempting to start now. Just one thing I don't get though is the triangular cam

When the "cam follower" sits on one of the cam sides, I just can't see how it's driven to an apex and around to the next side, I thought it would lock, please excuse my blondeness
