8043 with the claw from 42006 - problem

[Paul B Technic]

The other day while looking at my collection I thought it might be a good idea to mount the claw off 42006 on to 8043, last night I sat down and had a bit of a look at the best way to do this. Here is the end result.

The problem I have is that when the claw gets to the fully closed position it bounces around as can be seen in the video on my blog, what is an easy way to fix this? A clutch gear somewhere in the drive line for the claw?

Howdy mate cor that's some bounce in the old girl.... (cough...cough) the simplest thing to to is just add some sort of limiter to the out ward movement of the grab (were the grey1/2 bevel gear with hole is).

Looks like there's plenty of room to put a linear clutch (using friction pins with stop-bushes and a pin joiner) in that driveline. No idea if it would work though.

The problem is that the small tan gears are trying to turn the grab when it is closed,which in turn is forcing the grab to move outwards.

Use u-joint instead of bevel gears at the claw. You will need to redesign a bit the upper arm, to make sure none of the u-joints will meet more than about 50 (?) degree, otherwise they won't work.

Wow that is some bounce!

"Narr I don't feel like working today" Says the Excavator !

Reminds me of a Croc, snapping food!

Putting in a Ujoint should solve your problem.

Thanks for an entertaining video!

Looking at getting the 42006, would it be too much effor to put a scoop/bucket (much like the 8043)

So esentially doing the opoosite of whats happening here....

No that should be very easy to do,you would be better with a long LA though to make the bucket curl in and out.

Do you have a closer pics of that mod?

I bought a cheap 8043 and I want to turn it into 42006 by adding the claw..thanks!!!

Check here, last three pictures.

Thanks a lot!!!

maybe you can add second bevel gear with pinhole on the axle.

It will rotate in opposite direction, thus canceling movement of first one.

I have no idea if it gonna actually work. =)

[D3K]

That would work only for a set angle, effectively locking the movement of the Grabber, so the it wouldn't pivot freely around the axis on which it is suspended

Edit: hope that made some sense..:-)

(tried it on a car once):-)
