    I am building a magnetic switch but I need some ferrous parts and its proving to be impossible to fabricate or purchase anything suitable.

    I bought some 8mm square mild iron bar and tried to cut it to lengths of 10mm using a hack saw and file, but as shown in the picture the result is rubbish.

    The cut faces need to be square, true and flush.

    How can I fabricate something like this ?

    Or where could I get it made without it costing a fortune ?

    Or is there anything existing that I could buy, even if the dimensions are slightly different ?

    I need a quantity of 18.

    You would have to enquire about the tolerances, otherwise mrft's offer will be the better way forward.

    Meet up at a Screwfix branch wearing a red rose in your lapel !!!!!!!!!!!:confused:

    @free_flyer Do you know anyone with a chop saw, metal turning lathe or milling machine even a bandsaw and linisher?

    Thanks alll

    I looked at the eBay item and it’s priced at £4.74ea so 18 of them would cost £85.32 !!!

    They also state “Cutting tolerances are between -3mm to +3mm.
    Some material may have notches or burghs as a result from cutting and handling”

    Work has a small lathe but it’s only a 3 jaw chuck, we tried but it didn’t work as the part wobbled all over the place

    Work has a linisher but the grinding disc is quite rough. I got better results with a file.

    Work has a bandsaw but it won’t cut material as hard as mild iron

    Work has a small milling machine, we tried but it struggled and is only a very small basic milling machine (like a pillar drill)

    I never realised how difficult it would be to get a small metal cube !!!

    I have a shop on Etsy, search for Handmade West Workshop and drop me a message. We can sort it out from there and it definitely won’t be £85 and 3mm off
