Interesting wheel construction

UM ! An interesting construction, welded ? Rather a lot of spokes ! Traction engine, what type ? Noel.

Holes in the hub are probably deeper than the spokes so they can be pushed into place, rim slipped on and then pulled back out into holes in the rim and peined over before soldering at the hub. Though they may be threaded into the rim. Most I have done is 10 spoke.

I would have thought that the originals had steel or wrought iron spokes laid into the sand mould and the cast iron poured around them.

The spoke around half past 7 looks as though the end lump passed through the inner rim which would make life a whole lot easier?

pgk

yes that would make it easy if the rim hole were made to suit the largest diameter of teh poke then it would be wimple enough to turn the spokes, slip them all in from the outside and add the tyre to hide the holes, blob of solder to keep the spoke sin place.

Jason has made it obsolete.

The lumps at the ends of the spokes would seem to preclude them passing sufficiently through the hub or rim during assembly.

I'd probably try making the hub as two shallow rings each drilled for one sides worth of spokes. It ought to be possible to make a jig to hold the rim flat with the hub ring suspended above it so as put one sides worth of spokes into the rim with the other end just entering the holes in the hub rings. Pushing down on the hub ring would slide the spokes through the hub ring until stopped by the lump. Flip over and repeat on the other side so the rings end up edge to edge.

Silver solder it all together and fill the centre as desired. Probably two top hat shapes screwed together via a pair of internal and external threads. I'd be unsurprised to discover that a really skilled worker could make it accurately enough not to need silver soldering at all. Or at least only a few joints.

Alternatively I imagine modern glues could hold it together quite nicely.

But if adhesive is permitted plain spokes could be slid in through rim and hub with the lumps floating loose for subsequent glueing in place.
