Hi everyone,
It has been a little while since my last posting, so thank you to the other contributors who have kept the thread alive.
Certainly in my teenage years living in Clacton the ‘Speedway Track’ was on the Pier next to the Dodgem track and I certainly recall having a few races on the track, for optimum speed in the straights you had to line up the centre of the bonnet to one of the timber isolators between the metal power plates, and those hand brakes were fun, however most the time you wanted to keep the car going.
Evidence of the position of the track is still evident today as the newer steel frame workshop building and central under cover deck steel frame had to be made to accommodate the extra length of the track as it was slightly too long to fit fully in the under cover ride area.
The track was powered by a 3ph motor coupled to a 250/300 amp dynamo, two sets sat side by side in the centre of the track, only one was ever used at a time with a change over switch in case one failed. Up till quite recently one of these sets was still used on the Pier to provide power to the old Twist, the other set had it’s dynamo converted to a motor when the Speedway (Ark) motor gave up.
I discovered a couple of blue prints in the Pier’s old plan draw, sadly not dated or with any manufactures details, these must have been used as a template for the manufacture of the track on the Pier as both sets of plans differ slightly in detail but it gives you a good idea of the construction of the track, sadly nothing on the cars themselves.
Someone certainly had a lot of track plates to connect up, luckily you do not have to worry about the polarity, with most DC motors they will turn in the same direction even if the connections are crossed over, so the pickup brushes only had to be the right width and spacing so as not to short out the track plates.
