What happened at your workbench today?
- Thread starter Henri
- Start date
I manage to acquire a DJB small half brake just before xmas so have spent the last week slowly layering the sides together, good job I got some wood glue too 
Also good job Halfords filler under coat is the right shade for the inside.
test fit
You just can't have enough clamps!!

You actually finish one project before starting the next one? I didn't know that was even possible!

Well ........................ the issue is more to do with worksurface space during the colder months - working in the shed is rather uninviting

It is not possible, in my opinion.
Considering also it is one big project that will never end?
Well I often wonder what some people can do if they would have access to my space and tools.... the issue is more to do with worksurface space during the colder months - working in the shed is rather uninviting
I mean I see so much wonderful things appearing out of nothing, with such limited materials and tools, I often think they have a secret or two, but that is a thought.
Basically this is also a question for all of you to make a topic in scratch build.
Show us your magic.
With best regards Igor

Well, I had project in mind, then the chance to aquire a half brake came up and was too tempting not to start, then the parts for the first one where kindly delivered by a well-known practitioner of this parish, so I'm now like a kid in a sweet shop, get behind me satan

He'll just give you a push into deeper perdition. Safer to keep him in front where you can keep an eye on him. Or call the Right Rev. Rhino for an exorcism.... get behind me, Satan
Reminds me what a lovely kit this was to make, and the museum quality of the subsequent model. Pricey, but so well worth it. A real shame we are unlikely to ever see a second production run of any of the DJB IOM carriage kits...
Make it yourself?
I bet someone has a drawing or two, copy paste? laser cutter?
Just my thoughts
Yes, those things are possible, but the level of detail, the thought given to construction and the quality of the whitemetal castings makes it a quality product. I've tried to match it when laser cutting other rolling stock, but it doesn't come close...
plain lead? plain tin? or a mix.(dont forget to add bismuth or antimony)
I think i am able to tell you a secret or two to make detailed castings, there are some tricks.
There are no fixed parent metals for the alloy referred to as whitemetal: White metal - Wikipedia
I've done plenty of casting in the past -mostly aluminium- but it's not something I'm planning on doing at home!
The problem is the sheer high quality of the kit, for example each side is made up by 5 layers in order to recreate the tumble home, as for castings there's hundreds of them, hinges, Queen Post, step brackets etc I don't see how DJB made any money on them
Ah babbit, here is my experience with that:
Most babbit/white metal alloys are not good for casting fine print.
Excellent for bearings and some plates, cups and such, for juwelary it is nice to cast some crude forms and engrave them.
I think my casting with pb based metals (incl mixing)exceeds over 10 tons in the last 40 years and not only ingots.
When mixing in some copper (max 7.5%) in your pb blend you will have to start casting with pressure and keep a close eye on the viscosity, add sn to break the surface tension, but no zinc must be present.
Ect
Casting aluminium is a different story, i just started that endevor a couple of years ago, i am up to the point that i almost know witch alu type i must have for that particular project(incl zamak alloy)
Yes casting is fun, always keep an eye on safety.
I cast pb based alloys in the shed with plenty of air refreshment in a semi closed enclosure, indeed dont think to light about lead poising, it is a sneaky one and very slow, half time from your body is even slower.
Be aware of severe burns and even splashing of your molten metals, your not playing with boiling water
Casting alu, copper and such i do outside, the heat needed is just to massive for in the shed(i still dont have a small electric furnace).
Still casting ingots with those metals, and some sand casting experiments.
I think also most alu alloys need a certain salt? to give it during casting a better flow.
