I built my Crane engine out of a TEWK1 yonks ago, when I was a teenager in fact, the jib was wobbly and too short, it was a manual lift, and had a cardboard canopy.

I have decided now I have better skills I am going to re engineer it.

So far I have made a solid jib mount and tow jaw on the perch bracket, and I have fitted a proper Mamod derived 2/3 canopy.

I've also done a bit of weighing up with mecanno as to how I am going to drive the jib winch, and I think I now have a plan.

Where I am so far, the canopy will get a repaint, as will the whole machine when it is finished.

Here is the mocked up powered winch, got to make a few collars, trim up the meccano, and do some triangulation to stiffen things up but the idea works. Is super low geared so should work well.

Interesting Hedd, anything with Meccano in it and Im fascinated. That work drive should provide a very good reduction. I look forward to more images of the mechanism.

are you going to have reverse/forward with gearing or just the engine forward/reserve ?

Was far too low geared so I've swapped the 57 tooth gear for a 22 one, now lots better.

The engine will provide forward and reverse, though it has no clutch, I'll just take off the gear on the back

Jib this afternoon.

Pretty much done now bar the paint, just a few rough edges to sort out and tidy up. Perhaps some rubbers also.

The colpours will stay pretty much 'as Is' I think, need to black up the crane gear, the blue and red will stay, perhaps a black flywheel. We shall see.

So what so you guys think?

This is what I started with 15 years ago.

Building a fergus next.
