need something welded in Dublin

Stoner

A neighbour of mine has broken a bit on his lathe. He has a replacement bolt it needs a special head , that he also has welded onto it.

Anyone know someone who'd weld it please.
There is no real machining it's a welding job, very small but would need to be strong.

His a pensioner so I like to help him out I'll pay for it but I'd appreciate an option please

I used to get bits and pieces welded in the anco, fas training centre now, see what one is closest to you and give them a call.

I'd be very surprised if any engineering or fabrication shop would turn you away based on the story you've said above. I doubt many would even charge you.

Try Moto-engineering, they should be able to sort you out.

I could probably do that for you. I'd like to see a pic of the parts first (to see just how small it is)

Thank you very much I'll photograph it for you. He's a gent and very skilled himself.

Hopefully the photos above appear.

Can you explain what needs doing. The piece with the short thread and hole in the head is temp replaced with the long fully threaded hex set screw/bolt ?

Is it and old English mfgd machine ?

I'll presume you want to cut off the short bit of broken thread and weld the hex head to the round piece. That's no problem.

However, you say it needs to be strong and I'm not sure of the grade of steel in the bolt. If there is nothing or 4.6 stamped on the head then it's mild steel.

Personally I would buy a socket cap screw and tighten with an allen key. Cap screws are generally made of a higher grade of high tensile steel 10.9 or usually 12.9 and will take wear and tear better.https://www.google.ie/search?q=socket+cap+screw&biw=1366&bih=638&tbm=isch&tbo=u&source=univ&sa=X&ved=0ahUKEwjp4uj23pnQAhVLLMAKHUeUBXgQsAQIUQ

As I say that is the way I would go but it's up to you. If you agree then I'll help you ID the thread on the bolt so you know what you're looking for. It does look like 1/2" from the pic (uk machine)

If you want to go the welding route then that's fine.

That's what he wants. I'll run those options past him thank you very much

Yes it's an old unit. He says the bolt is an old BSF thread. I'm not familiar with those but the one he found threads in perfectly. Its what I would call an M7 if that existed is thicker than an M6 gutter bolt and smaller than an M8. The pitch and thread looks different too, flatter if you know what mean,

Smaller than M8 :eek: Well stab me vitals. All I had to go on was the tape measure which says 'add 75mm' on the back which would make the bed beam about the same/3-4". The pencil and the screw also makes that bolt look way bigger.
BSF is British std fine and is becoming harder to get but not impossible. If you count the amount of thread tips in one inch it will give a better idea of what we're dealing with. I did think 1/2" at first glance if smaller, possibly 7/16" (11mm) or 3/8" (9.5mm)
