Investigative Work in 2016


Brunel Swivel Bridge
turntable rotor wheel dimensions
First volunteer day of the year spent tidying up, continuing with renewal of timber stops, measuring the turntable rotor wheels and checking tie-rods and cast iron end fittings.

It is reassuring to see the relatively good condition of the tie-rods and cast iron end fittings, and if they are all like this we probably will be able to extract one or more wedge and re-tension the tie-rod on the south side. It appears from these that at least the end tie is in fair condition as is the internal surface of the iron as far as we can see. The photo near the pintle support appears to show that we have one quite thick tie and a second thinner tie immediately alongside it. This probably corresponds in sectional area to three of the single ties.

The diameter of the turntable rotor wheels was calculated from the dimension around the perimeter, measured a couple of times with a thin flexible wire wrapped around the circumference of the rim.

Timber Stop (involved more and more people as the day progressed)

Brunel Swivel Bridge
We came to add the support to the stop Graham had made in 2015

to our surprise on digging the hole for the support we found a stud with a
nut and washer that undid easily

Mike, Ian, Geoff, David, Bob, Martyn and Reece all needed to lump these
heavy baulks of timber around

Geoff gets out his trusty drill so the support can go back on the original stud,
being very precise with the level

will need further mods in May!

one of the wheel pit drain holes was blocked. There was not much room to get under the wheel
so the trusty back scratcher came in useful to clear out leaves and sediment
