Can anyone offer any advice on a injector issue i am having.

I turn on the water supply to the injector and water flows from the overflow.

I then turn the steam on, with some carefull balancing i can get a flow of water to the boiler but more often than not it end in a plume of steam from the overflow.

There is a slight waterleak from the shut off valve, both past the o rings and past the body into the injector, i have replaced the o rings in the shut off valve but its still leaking which is down to the wear, does anyone know of a supplier of this part or should i set about making my own ?

Thanks

Thanks for all the reply's, appreciate you taking the time.

Martin Johnson, whats the process to blow down ?

Do i just let the boiler pressure drop down to about 10 psi then open the valve and let it all out ?

Hello all.

Appreciate there will possibly be no right or wrong answer so am just after some opinions.

How should you store a 3" steel boiler.

Empty.
Full to the brim with an additive, when do you know is properly full ?
Half full with an additive.

Thanks.

Hello all, i know this is a long shot but..

I am trying to contact a model engineer by the name of Mr Michael Robinson.

Formally of Jericho Road, Cumbria.

If anyone knows or has any way of contacting him would you be able to let me know.

Thanks in advance for any help or info.

Ok, thank you.

Hello all.

I notice that their website is off line, does anyone know if its just a technical glitch ?

Thanks for the feed back,

Raymond, nice to see it progressing, not heard from you in a while.
Jason, you say 3 pin method but Paul only mentions 2 ?

Is this right ?

Morning Jason, thanks for replying,

Its this bit I'm not sure about, should i try and find / borrow a set of rolling bars or should i just form it round a bar ?

Hello guys, after some more advice.

Whats the best way to form the curved piece of the perch bracket to match the smoke box ?

Pratt Burnerd chuck labeled myford 30m mount.
Anyone know what the 30m stands for,

I have had a look and from what i can make out its the model number for a 4"

Someone said is stood for 30mm but as far as i am aware myfords standard spindle was only imperial.

Anyone know ?

Thanks

Thanks Phil, Thanks Jeff.

I have just been through the suppliers info and i think i have wasted your time, sorry.

Bush size is 65mm +0.019 + 0.030,

Hole size should be 65mm +0.00 + 0.019 (H6)

Thanks for your time both.

Brian

Hello.

yes, 63mm not 6.3mm

Thanks

Hello all, can you offer me some advice.

If i have a diameter 63mm with a h6 tolerance. (Guide bush)

What tolerance should i apply to the bored hole to ensure a good slide fit ?

I have never been any good with tolerances, normally i just machine to fit but on this occasion i am having the holes bored by a contract machining firm in spain and want to make sure i give them the correct tolerance.

Thanks for any help.

Thanks all for the reply's

Ordered another container so at least i have to correct stuff.

So far i am arguing over a minnie steering wheel with a bent handle. ( ordered last september, only just turned up )
A minnie chimney saddle casting which is undersize.

Now this..

Must be having a run of bad luck..anyway..

Hello guys, need some advice.

I have just bought and had delivered some enamel paint i am going to use to repaint a lathe stand, ordered some thinners at the same time but unforunatly the box must have been transported upside down and 75% of the thinners has leaked out the container.

I am sure if i speak to the supplier they will sort something out but i am wanting to get on and don't want to wait, does anyone know an off the shelf alternative ?

The paint is Paragon myford grey and the thinners is PT8

Quick note, please don't read this as me having a go at the supplier, all was good and i know these things happen,

Thanks all.

Bump.

Hello Richard.

Would you be able to post me a picture of how you did the blower valve setup into the chimney saddle ?

Thanks in advance.

Moving on..

Want to make a start on the chimney saddle, ordered a casting but not really sure where to start.

I’m ok with the machining, I am unsure what to do with the finished cast surface.

The casting has the usual flash and burnt on bits, anyone got any work on progress pictures of this part ?

Thanks.
