Thread: Brian's 1" Minnie Traction Engine
23/09/2019 16:07:00

Thanks for the replies chaps, does look offset but as there is no dimension i would imagine it’s just how it was drawn, anyway i’m going with equal about just to keep the wheel jig the same for both sides, thanks again

Nigel, see your point regarding having a clearance hole, i am not brave enough to key the eccentric, i have found an article in the model engineer that explains how to set the timing using a DTI so am going to try that method if i live long enough....

Bit stuck and i need a little help.
Just starting making the parts for the front wheels, looking at the drawing the hub looks to be offset to the center of the wheel but i cannot see a size on the drawing, anyone any idea ?

Thread: Injector help
03/07/2019 23:15:30

Hello Paul.

What size injector is that one ?

02/07/2019 22:49:40

Since found out the following, not sure if its correct but..

Steam inlet and outlet are normally the flat type, water feed can be coned or flat, depends on the injector..

Regards the performance of the injector i don't think it makes any differance.

Thanks.

Hello all.

Need some help if possible.

Are the union nuts and nipples used for normal fitting the same as you would use to connect an injector?

Also.

are both horizontal and vertical injectors the same in terms of performance?

Thanks,

Brian

Thread: Injector issue.
16/06/2019 21:19:42

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

Thread: Steel boiler storage.
11/05/2019 23:29:05

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.

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,

Thanks for your time both.

Brian
