Re: 1935 Ariel parts required

The valve lifter you want is 330-31, which can be easily modifies from a 330-38 readily available from Drags, except they are currently out of the bush. If i remember rightly the bush requires shortening a tad. I think the Magdyno gear cover shown is the style that was used from 1936 although I beli...

Re: 1930 Model B

The length of the brake rod will be found in the parts book but note that it is not easy to make, being fashioned from a 3/16 dia rod with a 26 tpi thread. The threaded portion is then rolled in order to put two flats on it thus causing the thread to increase to a bastard 7/32 x 26 tpi. They are ava...

Re: late mk 2 square four handlebars

The only difference between the 1955 and 1956 'bars is the position of the hole for the horn push. I know that the 'bars from Drags are correct as they have a copy of the works drawing, however handlebars are a matter of personal preference some people prefer to have their hands somewhere above thei...

Re: Wheel offsets

The centre of the wheel rim should be central between the spoke flanges, the distance you refer to is not the offset but a dimension from the brake drum to the edge of the rim; this will vary with the width of the rim whereas the offset figure will not. As I said the offset is the same for all wheel...

Re: handlebars

With W/NG parts it is not the date so much as the contract that specifies what is and isn't fitted. Some late contracts had the steel primary cases but then later on they went back to aluminium. Contract C 7,372 delivered between 28/5/40 and 6/6/40 is listed with 6400-39 'bars The next contract C 8,...
