Am I being dumb ?

[Neale]

Ok Neale thanks for the reply, I'm trying to get to a point where I can screw in a 3/8" bolt to the bush after I've ground the head off and fit it into a chuck capable of taking up to 13mm. if that makes sense ?

Sorry but I have to ask again - what 3/8" thread? If it's an old bolt, then it might be (imperial) BSF or BSW, newer might be (unified) UNF or UNC. Might, just, if it's a bit sloppy on its OD, be M10, depending on how accurately you have measured it. You might end up having to buy a matching tap and making it yourself, unfortunately, unless you have a kind forum member nearby with a lathe and good set of taps!

Edit - I see that you've more or less reached that conclusion!

Screw Size: 3/8" UNF x 1.1/2" long Thats what I found will fit in the chuck , thats why I thought it would fit in the bush.. that sounds naughty lol :)

I may have come up with a cunning plan :)
I found these Push Fit Stem Adaptors they may be strong enough for what I need , but if not I can cut off the stem and tap out the nut.. may work but hey I love a challenge :)

You maaaaay be asking a lot from Acetal, but you could always put a steel rod down the centre and bond it in.

Sorry mate - they may be metal, but most of the ones I have seen are acetal. I would give Bob or Chris at Context a ring and check it out. You could always use a brass hosetail ??? - Rob

It does say Plastic, I have canceled them . They are a bit steep if plastic as you can get a the same size stainless steel for £3 and they come in at £2.50 ?
