last time i looked covid was on .. and no bargains on ebay
well they are back
20 tonne one on this listing for £125
https://www.ebay.co.uk/itm/365475431080?
or you can look others up
EDITWOW ... you look on ebay .. it it does not list the one at lowest strait away .. you find one .. the £125 one .. and in the items advertised on page from other sellers is this ... now that's the bargain! you could not buy one i beam girder that makes part of one side from a metal merchant for that!
https://www.ebay.co.uk/itm/365232483173?75 the way you search ebay now is to find other sellers on the listing .. that are cheaper .. ebays deceiving people and leading you in the first searches to what makes more profit for them
keep doing that this way and you may find a 30 tonner cheap or same price as the 20 tonne one.
oh when you get it ... visit your local machine shop .. and raid their scrap bin for for the stubs that have come out of the lathe .. they will let you have them for almost nothing... you are looking for stumps of 2 inch , 2-1/2 inch, 3 inch bars with large holes in them.
all the best.mark
