oldypigeonpopper Posted March 30, 2020 Report Share Posted March 30, 2020 hello, weld a very large thick washer on the bottom lug Quote Link to comment Share on other sites More sharing options...
old'un Posted March 30, 2020 Report Share Posted March 30, 2020 The G part of the clap is likely to-be cast-iron, if so, it will have a very granular structure and does not bend easily without cracking but what have you got to lose trying.

fatchap Posted March 30, 2020 Report Share Posted March 30, 2020 I would try heating it and bending it back into shape, let it cool on its own though don't put it in water its liable to crack. Quote Link to comment Share on other sites More sharing options...
hodge911 Posted March 30, 2020 Author Report Share Posted March 30, 2020 Yea the G part deffo looks like cast its an old RECORD make clamp that was my dads and possibly my grandad's so I would if possible like to keep it and use it as they did . I've got no idea on how it got twisted ...... I'll have to think about ..... do I keep it as is Try to straighten it Quote Link to comment Share on other sites More sharing options...
Walker570 Posted March 30, 2020 Report Share Posted March 30, 2020 I would leave it B and if required go and buy another as well. If it breaks then you'll need to do that anyway and they don't cost the earth. Quote Link to comment Share on other sites More sharing options...
Gordon R Posted March 30, 2020 Report Share Posted March 30, 2020 Quote hello, weld a very large thick washer on the bottom lug I have just had the same problem within the last hour. Will a steel washer weld onto the cast iron? Quote Link to comment Share on other sites More sharing options...

Not sure how successful cast to steel welding is but I know you can braze cast and steel. Quote Link to comment Share on other sites More sharing options...

Gordon R Posted March 31, 2020 Report Share Posted March 31, 2020 I went into the garage yesterday with the intention of a bit of welding. I had one bent G-clamp, but found a straight one with no wobbly bit. Knocked the wobbly bit off, put it on the straight one and peined the edges over to secure it. I will look at the bent one in due course. Quote Link to comment Share on other sites More sharing options...
