I watched a youtube video some time ago by and Australian machinist and clock maker that goes by the name of Clickspring, if you haven't seen any of his videos then do yourself a favour and look them up, he is brilliant.
Anyway one of his videos is for a brass scriber which I have based this project on, mine is made slightly differently because I only used what I had lying around to get the job done.
First off I needed some brass rod, which I didn't have, but I did have a couple of old tap spindles that were brass
In the Video Chris used a sewing needle for his scriber tip, I didn't have any of those either, but I do have a heap of very small thread taps that I got in a lot deal off Ebay some time ago, they are really small and SAE so I will never use them, except for scriber tips
I needed to join the 2 spindles together, and obviously that would leave a join in the middle of my scriber, rather than try and hide it I thought I would highlight it, so I used a piece fo 6mm Aluminium in the centre as a contrast to the brass. It probably didn't contrast as much as I would have liked, but it turned out fine none the less. I used some 6mm all thread in the join, the tap spindles already had a hole from where the washer fitted in, so I didn't even need to drill, just tap the thread.
Then screw it all together with some Loctite to hold it.
Then it was into the lathe to turn it to size which is a nominal 9mm diameter, diam is not critical so I didn't even measure it. then taper the end and put some grooves in the handle for extra grip, sorry forgot to take photos whilst machining.
I drilled a hole in one end for the thread tap to be inserted, it was an interference fit so I had to hammer it home making it a nice tight fit. I then shaped and sharpened the tip on the lathe using a flap disc on the angle grinder.
And the end result.
Cheers Andrew
