How does Theodole restore?

MAGNET

The magnet is completely disassembled. The spool is ALWAYS winded with a modern condensator. All parts, except bearings, blasted with glass pearl. Bolts-nuts-studs-lids and clips updated. magnets from before 1930, nickel plated, and after 1930 technically chromed, that is mat chrome; zinc will not stay good. bearings new enclosed.

All non-original, broken or worn out parts replaced! Reassemled with conventional cable and lid. Comes with new type-plate. Remagnetised Tested under 'Live' circumstances. This means seriously heated, as can happen on a motorcycle. The spark must stay good at low RPM (kickstart) and high RPM (driving).

DYNAMO

The dynamo is completely disassembled. anchor and field are tested. The collector tested for breaches and thickness. If the anchor and collector are still good a new rope is wound around the collector wires. This is enamelled with isolating varnish and the collector is torn out. Eventually the forward axle is replaced, this is mostly, bent, worn out or beaten (especially conusses),if not, then restored. If the field is still good, new wires are attached, a new band is supplied and this wil be enamelled with isolating varnish All parts nickel plated or technical crome plated! All non-original, broken or worn out parts replaced! Reassembled, poled and tested. eventually supplied with electronic regulator earthed negative or positive. The dynamo can also be converted to 12 volt
