Thread: Part built Allchin 1.5 inch
02/04/2020 19:33:41

Hi All

just a quick question, would I be shot by the traction engine supporters if I painted my Allchin tender Black?

is there any Allchin I could model mine on other than the maroon, I’ve had huge trouble with finish with painting the tender let alone chips etc, but satin black stove paint goes on beautiful and is hard wearing.

the wheels, boiler cladding and crankshaft area are maroon.

Hi All

I hope everyone is well, quick question I started to spray paint my engine with acrylic spray paint.

the boiler parts with VHT paint, my question is the boiler cladding would the acrylic spray paint bubble or go soft and waste my time?

thanks in advance

Hi All

i hope everyone is well, considering the situation at the moment.

i have a quick question regarding the Allchin safety valve, is there any drawing discrepancies on this part of the build.

the valves that drop down into the steam passages, should these be a sliding fit? It’s not very clear on the drawings, I have leaks around these valves even at low pressure.

does anyone have any pictures of the finished valves for reference.

kind regards

Good evening

Could someone advise a uk machinist who would be able to machine two eccentric straps.

i hand made these last time but I’d like a better fit, I have two new castings but finding it hard to find anyone on google who machines live steam parts.

funds are not a problem but finding someone is, any advice greatfully received.

Hi Clive

Interesting! However when I put my ear to the various areas it does seem to be coming from the crank

Hi Micheal

unfortunately they are solid bearings, the play is more of a twist that forward and back,

i guess I’m bemused as the engine ran quiet yesterday but just all of a sudden started knocking.



10/03/2020 18:46:22

Hi All

if anyone gets time could they please advise the likely causes of knocking when the engine is running.

it started all of a sudden, I can see and feel movement in the crank bearing which is odd as it’s all brand new and started all of a sudden.

the crank moves ever so slightly in the bearing forward and back, I think this knocks and vibrates through the hornplates.

is my only option to make new bearings for a sung fit on the crank, it ran beautifully yesterday but the loud knock started today. Will this movement just come back even if I start all over again, I had plenty if oil on the area.

thanks in advance.

Hi everyone

So the Allchin has been on the back burner for a while now, no real new progress other than fitting the safety valve and trying to find an easy way to test this to set blow level, any ideas?

I have ran the engine at Christmas on air and it runs very well I think in forward and reverse, I’m just setting up the control rod and lever now.

Hi Jim

everyone has the right to be on the forum, I’m presently building the Allchin in 1.5inch scale.

29/12/2019 16:09:05

No real updates, other than running engine in on air.

i can hear some leak from the clack valve I made and I can see bubbles in the lubricator so there is obviously a leak from cylinder back down the pipe so I’m going to have to adjust the spring or adjust the ball.

however it runs so I’m happy.

i have the video added to YouTube as mentioned for anyone who would like to see the engine running.


24/12/2019 17:56:15

Thanks John, I will take a look

24/12/2019 15:05:32

New YouTube video added, under “Second Allchin air test”

Merry Christmas

dcbb95fa-3560-4a79-8963-04336d075d5d.jpegPulley wheel made, a lot of hand shaping as I had no tool to cut the recess but not looking too bad,

still trying to source the correct size bevel gears but struggling.


22/12/2019 21:03:10

Hi All

ive been doing some bits to the engine but no new pictures yet but there will be soon for anyone who maybe interested.

one question I do have is sourcing the bevel gears for the Pickering governor, has anyone purchased these and know of a supplier, I’m going to keep an eye on eBay just in case as I need the pulley wheels as well but these I maybe able to make.

Hi Brian

Great work, looking great 👍

17/12/2019 21:34:43

Very nice work Brian.

Hi Brian

yes I would probably you epoxy myself, as flux can seep out over time but I’m no expert.

i look forward to the updates, keep them coming,


26/11/2019 17:00:45

Wheels look lovely and neat.

26/11/2019 17:00:13

Out of interest what part gets soldered? I bet that’s hard to keep neat.
