Any good quality steel stockist should be able to get you that size of billet. I got a 400kg 350dia x 550mm from Franklin Steel. Was expensive though at approx. £800
any idea on a source for such a thing?
Not fixed on those dimensions just something similar.
iv'e looked at the plate option but I was thinking there must be somebody out there who knows where these things are sourced, round would be just as good!

worth it though as it takes less hits for big strainers than some of the wee lightweight knockers with 200kg weights.

Box section thick plate either end fill with lead.

McHale trailed wrappers have a good lump of counterweight opposite the loading arm, have never measured it though
I see from your location that you're mid wales- have you tried Dyfed steels? Other options could be Parker steel, precision profiles or Malthouse engineering. As a suggestion maybe look at a plate thickness that is likely to be "on the shelf" eg 25/ 30mm thick plate. Doing it this way also has the added benefit of allowing you any shape that you want so you could for example have a guide hole profiled in along with a recess on one side the allowed it to locate about the main shaft if that makes sense?
i keep thinking that but i'm not sure on buying lead would come out cheap!

Always the kirk roof .......... (joke)
Makes a lot of sense, i've looked into sandwiching 4 x 150mm square bar or 6 x 50mmx300mm flat bar to make up the weight but the profiling to also make the recess is a good idea! - I work in Manchester during the week so I can easily access quite a few stockists.
ill send some emails off tomorrow to dyfed and parker etc. as sugested
Wouldn't be a hard job for a foundry to pour a block.
