Hello Vixen

The first parts I am making in the latest project are for an OS60 control line speed engine, these are two different types of exhaust stubs for connecting the mini pipe to the engine.











The image only shows the larger type but the smaller one has a 3D undercut, which was the first time that I programmed an undercut with a lollipop tool.

A fellow competitors has had 18 piston liner assemblies made in the Ukraine, these are a big step up from the OS piston liner, but that is beyond me at the moment.

I will make up a number of different length mini pipes in the next few days, after that I will be making a new front housing with loose fit ceramic ball races, from other engines that I have used it is critical to get a very low drag bearing setup.

More to follow.

Welcome Dell. There are several here with Cowell's lathes  as well as Sherlines and Taigs so you will find kindred spirits here.

Hi Gerritv,

Do you think this polisher would be useful for finishing small metal parts as well as PLA?

Just came across this via Hackaday, seems like a potential good way to smooth prints: https://www.thingiverse.com/thing:3666116

:hi: Dell

Welcome to the forum. There is nothing like a bit of cold metal therapy to keep mind and body active.

Thanks for the welcome I havenít made a clock but thatís not to say I wonít I just service and repair torsion clocks, and yes they are clockwork engines.
The reason for the lathe is spares for antique clocks are getting ( or I should say have got ) very hard to find. I have two that the mainspring has exploded and split the barrel so that will be my first project but as I havenít used a lathe for over 50 years I am going to make one or two out of aluminium to start with before I try with brass.
