How to make a brace...
Hello
I’m mostley working with wood and are a totally novice at metalworking.
I’m posting this to get some ideas about how to do stuff in general, and to solve a spesific issue.
I would have liked to make a brace like the one shown in the picture.

It will have the same usage as in the picture, to reinforce my wooden vice screw.
How would you go about to make a ring lile that?
- what metal, may scrap do? If not, where do you non pro source metal from?
- I assume you start out with a strip of metal, heat it and form it? But how do you close the ring?
- How do you get the black color? Is it special type of metal or treatment, or do you just paint it?
sorry for the novice question, but it would be nice to be pushed in the right direction.

For this purpose I would go to a steel/scrap merchant and buy a short section of black pipe and cut a piece of that.
Where I like the pipe lengths are typically from 200 mm upwards and cost AUS$1 a kg.
You might need to be creative and buy the pipe AND then make the hum up to suit rather than the other way around.
- How do you get the black color? Is it special type of metal or treatment, or do you just paint it? .
One would be to heat it to near red heat in a BBQ flame and then dunk it in mineral oil.
There there are various traditional metal blue/blackening methods.

Another is repeated paint with Tannic acid and then a final coat of linseed oil.

Hi TEK,
Welcome to our forum.
Chisel and file handle makers sometimes use a similar device called a ferrule to reinforce the end of their wooden handles to reduce the possibility of splitting.
These handles are turned in a lathe and the diameter is matched to the internal diameter of the ferrule.
This would call for obtaining the ferrule ( your ring) and measuring its internal diameter, first. The timber part would be then turned carefully to that diameter for a tap on friction fit which could be supplemented with an epoxy.
The ferrule ring should be square and true and could be marked out carefully and cut with a hacksaw and dressed with files if thats all you have.
The coloring of the ring is as BobL has described.
What sort of tools do you have available ?

Hi BobL,
In your pic with the three blacked items,what do you call the third one with the hinge pin?. I see them on machinery but can't find a name for them. Hoping to buy some of them for projects.

Thanks for the welcome )
Hmm, as it is I have already made the vice screw. I now understand that it would have been easier
to have thought about this earlier on - so I could have got
the ring first and adapted the screw to it.
My current (metal) toolset is:
- welder
- an anville (just did a bargin, those are madly expensive
and hard to come by here)
- hammer
- some iron files
- some pliers
- cutters for sheet metal
- a angel grinder (125mm)
- hand metal saw
- drill press
I also think that I’m able to make something to use as heat for making smaller items red hot if nessesarly...
I have actually made a cyclone from sheet metal (0.7mm) earlier. Kindof forgot
about that...

The next thing you can do is see if you can find some pipe that is almost the same size and cut a ring from it.
If it is larger that the hub remove a segment from the ring close it up in a vice and weld it. The resulting ring will be round enough for your purposes
If the pipe is smaller, cut two rings from the pipe and split one and open it up and take a segment from the other slightly flatten it on the anvil and weld it in place.
It sounds like a lot off work but unless you have access to a set of industrial rollers (or a forge and a lot of skill) forming a ring from flat bar is MUCH harder.

As BobL says above you will need to take a segment out of your pipe for a ring.
Me, I would use black pipe, as welding a galv pipe will be difficult.
To obtain the precise size, measure the step on your wooden part by cutting a strip of paper to lay around that circumference and cut it at the overlaps with a razor tool. The resulting length of paper strip is now the finish circumference length for the ID of the black pipe.
Marked carefully, you should not have any trouble slicing off the required width of black pipe with your angle grinder fitted with a 1.6mm thick cutting wheel.
Lay the strip inside the pipe circumference and mark off precisely.
Cut off the excess with your hacksaw and and weld the join.
Dress off with the angle grinder and files and blacken by your chosen method.
Post up some piccies when you finish it.
Good luck!
