'Glueing' together a Watts governor

I am building, in steel, the watts type governor of a Double Tangye engine the bottom arms of which cradle the balls via a 1/16" pin through its centre. The top arm, also 1/16" steel fits into a 1/3rd depth hole in the ball. having made the bits (without breaking a 1/16 drill) I am faced with the job of sticking the mechanism together and am seeking advice as the best (least messy) method of fixing the thin parts into the ball and cradle. Locite, Araldite, soft solder or silver solder (paste).

Suggestions based on experience very welcome.

I’ve never built a governor, Tony ... but I have used Loctite ‘retainers’ 638, 601, etc. very successfully, on many occasions, for what I would consider very similar jobs; and that would be my first choice.

Apologies if I fail your specific “based on experience” test, but that’s the best I can offer.

What Michael says, 638 or equivalent will be fine, you may want to file a slight flat on the male part so it does not act like a piston when you push it into the blind hole and try to pop back out again.

Dare I say I've glued on bigger balls than the ones on the Tangye and they have not come off yet.

Thanks for the advice Guys - I have some 638 and will use it on all the spindle connections into the balls. I have used silver-solder paste to assembly the lower arms which took care but worked because the component were all of similar size (thermal mass) but it won't work with fitting a same rod into a comparatively massive ball - so loctite it is.
