FT: Frame (Twin) Early Rapide Research: 1947

[david bowen]

I think if you drill a 2BA hole between the 1/4 and 5/16 holes the FT203 will hold the plate to the FT22as by this method your plate self aligns for the spring angle.

I am thinking about this No42E mount, based on all I have read (Throwing Light) and using the photo as reference, that the 42E mounts under the RFM leg bolt......which supposedly on an early B Rapide is a 5/16 BSF rather than the later 3/8 BSF. I have not confirmed this BSF personally yet. I flipped the parts manual MO22 drawing to show my thoughts.

I believe this Miller No42E switch was only used on the first 341 Rapides, up thru chassis number R2340.....late 1947/early 1948.
After this, there were FT22/4 rear guard stays added along with FT203 special bolt and a PR39/1 Lucas stop light switch.

Just to confuse you further, my "H.R.D." Parts list from around October 1947 shows part no. 561 going through from the INSIDE with 142 and 143 nut and washer outside. However, I have an early "B" R.F.M. with a 5/16" B.S.F. bolt going from the OUTSIDE in this location

Your faith in final machine inspection when in the midst of post war shortages rationing lack of fuel coal and powercuts is perhaps a little unfounded to say nothing of all the long gone previous hands that machine has gone through.

Bolt 597. washer 501. were put in position by the fabrication dept. it held the RFM in position for brazing over a dowel, and painted at the same time as the RFM.

Same method on the FT1as UFM, to FT1/2as Headstock, FT125 bolts, FT126 nuts, then painted

Ee, lad I've little enough faith, these are just confusing, or confused observations. My knowledge is never in the "Thou speakest and I tremble" class! And you're right, most Australian early Twins went on the Speedway, and you had a half-pound of gravy beef with wot some of those fellers did.

Looking for help on early windscreen and fairings, of this style, used on Vincents.
What is the make and model? I could reproduce this but more photos would be a help.
Thank you
