|Thread: 7BA Grub Screws with socket (rather than slot)|
I have looked at all the usual suspects, but can't find a source of these. Not keen on the slotted ones as it's too easy to damage. Any pointers would be appreciated.
|Thread: Stuart engine paint colours|
Many thanks all.
Can I ask David George 1 what is the exact blue colour used on your engine? Looks very smart!
Just completed my Stuart Half-Beam and it's time to paint. Frankly I am fed up with my usual green, black, and the occasional bit of red!
Can anyone offer suggestions that have worked out well?
Pink and lilac are out of the question! Obviously needs something that suits the period.
|Thread: Myford 'Between centre boring bar'|
Brilliant - thanks chaps!
Just wondering if anyone else has bought this item? Bar is OK and drilled with two holes at 90 degrees apart. Came with three single point cutters, but there is no means of securing the cutters in the bar. Myford being less than helpful! You wouldn't think it was difficult to return a phone call!
|Thread: Just breaking the Ice|
Doesn't everyone start with a Stuart S50 engine - from castings of course? Lots of youtube videos of course, some better than others. i would recommend 'Learning Turning' as a very good tutorial.
|Thread: Mis-aligned hole in Stuart Half-Beam|
Cock up on my part, but I could excuse myself as I was interrupted during the machining. Anyhow, I have drilled the centre hole in the beam off centre. It is drilled to 3/8" and should end up as 1/2". It's just about 1/8" off centre.
What are my options? I thought about using the mill and rotary table to open up the hole, but centred, to more than 1/2" and then fitting a brass bushing and then drilling that (on centre) to 1/2". Or perhaps mounting the beam in the lathe and using a boring bar to produce a centred hole.
Any advice gratefully accepted. Kevin
|Thread: Help required to fix Scissor Clock|
I have been asked to repair a beautifully made Scissor Clock (built from Wilding's book). Frankly, it's beyond me. The scale is way to small for me.
I am looking for an amateur expert to do this work and of course I will pay all expenses. Ideally 'down south' as I am in Guildford.
Regards and thanks for reading, Kevin
|Thread: Finishing brass straps around boiler|
Below is 'the usual way' of securing thin brass straps around a boiler (or condenser in this case). It's pretty ugly and I usually try to hide them out of sight.
Is there a better way of doing this? I was thinking along the lines of a very small jubilee clip arrangement soldered to the ends of the straps.
Regards all, Kevin
|Thread: Help in identifying an engine|
I am not sure if this engine is completely original or based on a published design. Can anyone identify it? Possibly not obvious from the images but it stands about 100mm high.
|Thread: How can a steel thermos drinks flask fail?|
Same problem here! I put a coffee and a choc-ice in before coming to work and now all I have is brown sludge!
|Thread: Steam plant layout|
Indeed - it's a Stuart 501 It was in horrible condition when I got it, but stripped it down and removed (carefully) the asbestos panels. One cock-up was painting the side panels and I didn't use heat resistant paint! It bubbled up and fell off! Stripped down again and repainted with very high temp paint and all is well.
(I have a big 504 boiler and that is being paired with a No 9 and a No. 1 - hopefully there is sufficient pressure and volume to power both?)
Many thanks for all the replies - super helpful! Can anyone point to a design of an oil separator?
Finally connected the steam pipes between a Stuart 501 and a 10V and an S50. Very pleased to see it all working.
Short video of it running: https://youtu.be/9fXT8Nre7H0
Couple of questions:
1. Obviously need to sort out exhaust! Would 1/4" tube be ok for that?
2. Is it worth installing a condenser?
3. What about the layout? Ought I try to make it look more like a proper installation? Proper brick flooring and guard rails? Not planning in adding little men operating the plant, but would welcome advice!

|Thread: Virtual Meet Ups|
Please add me to the list!
Yes, count me in!
|Thread: Please Avoid Political and Partisan Issues|
Well done Moderators!
I get all the politics and nonsense I need elsewhere. Reading posts here is the same for me as going into the workshop - just me, a few like minded people and all that concerns us is reshaping lumps of metals!
Let's keep this just about our hobby.
|Thread: Super 7 Spindle lubrication|
Getting my Super 7 back into a reasonable order, and spotted the cotton wool wick in the oiler for the spindle was missing. I have replaced it with a new wick from Myford, and topped up the oil. The oil level isn't obviously going down. Is there a means of finding out whether oil is actually getting to the bearing?
Regards and thanks, Kevin
|Thread: Is Iron / Steel endlessly recyclable ?|
Looking at the swarf on the workshop floor made me think about the above?
Given it could be melted down, could it be reused? Think more of industrial waster than my pile of chips!
Would this apply to cast iron, steel, all the usual forms.
|Thread: Removing (decorators) paint from Myford Panel|
I have an Myford industrial stand with lovely control panel, but sadly speckled with decorator's dulux some time ago. What would be safe to use to remove these spots?
