Breaking threads suggests a tension problem. Have you checked that? If it was running correctly before don't touch the bottom tensioner unless you have eliminated everything else. There are lots of You Tube clips that can help. How well maintained is it? Has it been thoroughly cleaned and oiled recently?

i was about to suggest a thorough clean and oil the bits that need oil

the top tensioner can get a bit clagged with fibres/rust/muck etc(if it is pitted you might need to either repolish it or replace it)

sometimes the spring is just too "baggy"to keep an even pressure on the plates but usually there is enough spring in it to get the required "grip"

the bottom one probably just needs a good clean,tis a bit more technical to adjust it than the top one

both need to be working well to prevent both the problems you have had

as above plenty of video tutorials.

broken needle is often top tensioner issues

bottom tension is a usual culprit, I have the same problem on Singers old and new

If it is any consolation, I've found that parts are still available even for very old Singers...when in South Wales the Singer machine maintenance place just off the ring road in Newport was great. trying desperately to remember where it was...not the turning by Coleg Gwent/Nash, but the next one over...

He's reasonably confident that it isn't bottom tension because it still breaks the thread without the bottom spool.
Current theory is that the thread is not properly finding its wayaround the shuttle...

a good fettling is the best next move , clean and polish all the bits the thread touches between reel and needle and underneath as well

You don't say how old but this might help.

threading the needle the wrong way or replacing the needle in the wrong way have been the issues with my old machine. 1927 and still going strong.

I was going to suggest the same thing Lorraine. Most machines will only take needles one way round as there is a flat on the needle top, but threading the machine the wrong way will often result in problems.

He may have broke the first needle by putting it in the wrong way, but I think he's been more careful since...

a quick thought about needles,blunt ones are more prone to breaking as they tend to bend round threads rather than piercing through them.

i usually sharpen them on a smooth fine grain whetstone from new and every few hours in use.

it only takes seconds and seems to make a difference.

I assume the second and subsequent needles were new, and therefore sharp.

even new needles benefit from sharpening ,factory tips are often a curved taper,sharp has a proper spear point.

it isnt as important with light material but you will really notice the difference with denim or rucksack material

It has stopped breaking needles now though.
