Hopefully with the help of the attached photos I'll explain it better.
In the first photo you can see that the white part with the upright is a single cast piece, that holds the silver post, ( the post is attached to a heat press so theres a lot of weight there ).
As you can see in the second photo the part has literally snapped ( I didn't realise how strong I was

)
My idea is that if I get a piece made with the flange and a bigger upright I can just slot the upright piece in to it and it should do the job.
Any further advice is most welcome and cheers for the help so far.
