Hi

As it says in the title I am looking for a supplier of this size of pipe unions

Can anyone tell me who can supply these here in the UK

Thanks

Dougie

So It seem to be a bit of a mystery then?

Dougie

Thanks Jason

Thats the one, it needs some repairs and I wondered if anyone recognised it

The owner bought it second hand and has no details

Dougie

Not sure how to do that, can you help?

That link above dosent work

Can anybody tell me how to put a link into this thread?

Thanks

Dougie

Hi

I bought a Chinese lathe from the same supplier a few years ago

I had a new chuck sent out to try to fix a problem like yours, it was worse

A new tailstock arrived to try to rectify a problem it had

The gearbox worked a bit better after I removed all the sand and swarf from inside it

Finally a new lathe arrived to replace the one I had as the problem with the tailstock could not be fixed

My big mistake was taking two hours to load the faulty machine into the delivery waggon and setting the new one in the workshop before checking it. It had the same fault with the tailstock as the original !!

I got a refund and bought a second hand british machine, this was the advice I got in the first place

In Scotland the Summerlee Heritage Museum in Coatbridge is well worth a visit

Bills tool store in The Gallowgate in Glasgow usually have stocks of ex MOD tools

The maritime museum in Irvine has lots to see

Hi

My son has been given a ST engine complete with boiler and dynamo to restore

Inside the boiler casing is some insulation, could this be asbestos?

Hi John

I want the nuts to look like the originals which are pre war thickness

So around 25mm hex and 12-13mm thick

Thanks

Dougie

I have a Harrison M300 and could in theory cut the thread but I have broken every screwcutting tool I have and get nowhere and I am rapidly running out of hex bar

I was out in the workshop earlier and may have come up with a solution, if I turn the old nuts to a diameter then bore a new nut blank to suit and  silver solder both parts together

20 on the mandrel and 45 0n the leadscrew gives a decent useable thread for a project

Thanks Ady, but I dont know what that means

Dougie

Thanks John, PM sent

19/32 x 18 is a thread size on some beer kegs I have discovered but cannot locate a tap or die

Dougie

I have come to the conclusion that the thread I was trying to identify must be some kind of special

The stud the nut fits on is 15mm dia, the threaded part is 14.8 mm and is definitely 18TPI

I have tried to cut new nuts on my lathe but I am having no success so I'm hoping someone with better ability than me can help

Can someone make me four nuts to the sizes above?, I can supply the blanks and would cover any costs

Thanks

Dougie

Hi

I hope someone here might be able to help me identify an unusual thread size I have come across on one of my full size projects

The item in question has, as best as I can measure 18tpi, and is just over 14mm dia.

A 9/16 x 18 UNF tap will enter the nut but is loose although a 9/16 x 18 die will not thread onto the bolt

The thread angle matches the whitworth form better than the metric

All the other threads on the engine are metric, mostly fine, I thought it was M14 x 1.5 but my thread gauge shows that to be wrong

The engine is a French design built in Wembley probably late teens early twenties. Were unusual or uncommon imperial sizes used in those days?

I want to make replacement nuts as the originals are rusted badly

Any help would be greatly appreciated

Dougie

Hi Trevor and thankyou for the offer

I have some sifbronze rods but the problem is getting the iron hot enough

From the advice above I think in the first instance I might try to braze, I have a oxy propane setup but I need to buy the correct nozzle for this setup as the acetylene tips I have dont work

On that note, can anyone tell me what kind of nozzle/tip I need for oxy propane?

Thankyou

Dougie

Is it possible to "thin" JB weld so that it could br forced into the cracks through a syringe and needle, say 12 or 14 gauge
