The Redfin Project

New Twinshaft Car and Motors

The name of Redfin motors and the man behind the operation, Alex Phin is already well established in the model aeroplane world for the range of retro motors he supplies. Now he is meeting the needs of the tethered car fraternity with the new Retro 15 twinshaft. This is similar in style to an Oliver Tiger but does not pretend to be a replica. It shares the same general layout with the flat mounting plate and cylinder axis angled up slightly. The crankcase is a super quality casting with the Redfin name and model name prominent. The internals are again not copies but those used in the immensely successful Parra motors. A peripheral jet venturi is another obvious departure although this could probably be changed for a 'curly' style one to allow the anticlockwise running that most commercial castings are arranged for. The quality of the Ukraine built motor is excellent throughout down to the dummy brake drums machined on to the inner hubs. Currently on sale for less than £200 this engine represents a very good option for potential builders. Go to the Redfin website www.redfinengines.com for further details.

Oliver style fuel cut offs are also available from Alex at £25 and they do look spot on, both for his car, Oliver replicas and other designs. Alex tells us that front and rear tyres for the twinshaft motor and car will soon be available and he will have a batch of these in similar numbers to the cut offs (Covid restrictions notwithstanding at present). The chassis pan for the new car has been delayed slightly as the opportunity has been taken to alter the design and pattern to accommodate damped front suspension.

There is a considerable degree of interest being shown in this project, especially with the news that the track at Buckminster is now complete and will be in operation as soon as restrictions can be lifted.

We have been informed that Maris Dressler has performed a test run one of the engines and has reported very favourably about the quality, ease of handling and performance, and recorded it as being more powerful than an Oliver original. Food for thought?
                                                                               Thanks to Steve Betney and Alex for all the details.

Pre production prototypes of the Redfin car kit have been allocated for comments on design and construction and Oliver Monk has very quickly assembled and appraised his car as follows while Steve Betney and John Goodall have spent a little longer to include delightful, scale bodywork.  It is very many years since a kit of this nature has been available to tethered car enthusiasts and we await further details once production versions are to hand.

Oliver Monk puts together the prototype

Alex Phin has sent me one of the first batch of four Redfin tether car chassis for me to have a look at. When I found out it was coming I ordered a twinshaft engine and shut-off to go with it.

This is what came in the box, the main part of the chassis is steel as well as the tether arm. An adjustable front suspension unit with damping and the axles are steel. The tyres are test mouldings to prove the tooling, standard tyres will be black.

The front wheel hubs are ball raced and complement the rear hubs that come as standard with the Redfin Twinshaft.

This is the car all put together, it was an easy build all the parts are accurately made and nicely finished. I put it together on the kitchen table at a friends flat in Filey. One or two bits need a little modification but will be sorted for the main production run, along with a tank.

Its going to be an ideal beginner’s car all it will require is a body to be made and it will be ready to run.

The chassis will come with some drawings of suggested body shapes to give people an idea of where and how to proceed.

Thanks to Oliver and Alex for this preview.

Steve Betney completes his version

Another of the prototype chassis went to Steve Betney who has built his up as this rather lovely Ferrari Tipo 500 F2 car from 1952/53. A more detailed build article is to follow when the final version of the chassis kit is available.
 

John Goodall's Vanwall

John decided to incorporate a different design of front axle mounting on his version in order to simplify the construction and provide further feedback to Alex on this aspect of the design, which should be altered significantly on the production chassis.
 

     
     
     

The Redfin twinshaft motor is providing power for a number of other car projects and restorations that we will feature as they are completed. One of the first was Oliver Monk's 'Car for Buckminster' based on a set of replica Oliver Mercedes castings, for which he provided a very detailed constructional article.

A Retro member has used a simple plate chassis with damped front suspension similar to that in the Lev Sprints Junior car kit The plate is milled from 8mm aluminium to allow ground clearance with the correct sized tyres supplied by Alex. Strictly non scale body is awaiting supplies of epoxy, glass and warm weather.
