Pushrods v Aluminium Arrowshafts


Recommended Posts

Hello

 

anyone used aluminium arrow shafts for making pushrods?

 

If so, can you recommend a source in the UK.

 

Googling it shows plenty of suppliers on line but if any one has real world recommendations all the better.

 

Also, if anyone knows a source of steel 3mm left hand threaded rod (then its possible to make a turnbuckle type pushrod like the Control Line stunt guys use).

 

cheers

IIRC Modelfixings sell lh thread 3mm rod.  I've always called 'turnbuckles', 'bottle screws' when I used them for dinghy mast stay adjustment.  I think thy're the same thing.

I've never found a source of 3mm studding with a left hand thread.  I did find some welding wire in just the right diameter to take a LH 3mm die.  I have also centre drilled some 6mm alloy bar and tapped 3mm Left and Right into opposite ends.  It works but 3mm taps are very brittle.

 

Carbon arrow shafts are useful, not sure that I've seen an alloy arrowshaft.
