Has anybody got a bottle screw body for me as per the photo? I have the male threaded components but am missing the tubular portion on one side!

Have you tried a chandlery shop for rigging screws?

Tony, as a matter of interest, what parts are you joining/adjusting?

Good question, Dick. I have studied the photograph for two and a half hours (I have told you 10,000 times - don't keep exaggerating) and I still have no idea what a bottle screw is and what it is supposed to adjust.
I wait with bated breath for a complete explanation to what at present is just one more of those mysteries of life.

I don't know what it's to adjust (radiator tie bars?) but a bottle screw is the same in principle to a track rod - undo both lock nuts on the track rod ends, then rotate the bar one way or the other to adjust the length...

Just a guess, could it be for adjusting a door to fit?

I expect it's the adjuster for the footbrake - left hand thread one end, right hand thread the other. As you rotate it, it pulls the two joined components closer together (or further apart, depending on the rotation..)

I thought it may have been the connecting rod between the carbs

Hugh,
I'm no metallurgist but I would be concerned if a slim brass sleeve with a hole drilled through the middle was part of my foot brake linkage even if the stresses are push rather than pull. This part on my M type is a substantial octagonal steel arrangement twice as thick as Tony's brass one and no hole drilled through the middle.

This is the adjuster on the brake rods on the early M Type, so two each side, fore and aft. It links the rod to the short cable section at the wheel end. The first time I saw one it scared me stiff to see that it was made of brass and had its structure so badly weakened by the hole for the tommy bar. I would suggest it is replaced by hexagonal steel bar with no tommy bar hole. For once I think we're justified in abandoning originality in favour of "safety fast!".

and to be fair, the one on my M Type was a far more substantial affair, something that looked more like the central portion of this..

But this is not the pedal linkage. It is on the four brake rods used on the early cars before the modification to all cable.

Yes, Malcolm is quite correct! This is on the M-Type brake rods. LH thread one end and RH 'tother. I am informed that this is called a bottle screw (closed) and the other one shown in one of the threads on this subject is a turn-buckle(open centre). The latter does look rather agricultural on my little M so I was trying to find the copper bits, if possible.
Hexagonal bar will certainly do but we are metric here and to get 5/16 BSF left and right hand is almost impossible. I priced a tap for the LH, special import and R4 000. about GBP 230! |
