In learning how to use my lathe I am doing some basic projects.

First up is an engineers hammer.

I would like to cold blue this.

I can get small volumes from gun shops, however I know you can get 500ml (or there abouts) bottles.

I have trawled my way through lots of engineering suppliers and can not find anyone who sells this.

Anyone have any supplier ?

After the hammer comes a tap follower, then a die holder for the lathe.

After that I will see if the guys at work can mill me some tool holders for my QCTP.

One I have enough stuff sold from my shed I am allowed to buy a mill for home, and then I can learn to use that too.

Its a complete p!ss me off that the government years ago stopped high schools like PNths QEC having night classes, they were a brilliant place for people to learn new skills .

Hello fellow hobby engineer.

I took it up a couple of years ago after watching clickspring.

Currently rocking a myford super 7 and trying to build a die filer kit from Hemingway kits. Longterm plan is to make a clock but only finished the frame so far. Also bought a couple of engine kits from UK.

One thing I wish I had bought earlier than I did was an indicator holder with single screw to tighten it as made it much easier to use an indicator.

I can't help with large volume gun blue as my small bottle is unused. I have also never been able to source dikyn blue here either.

Hope you are watching blondihacks, clickspring, Mark presling, artisan makes.

PS I know what you mean about night classes, I did a welding night class through the polytechnic here in Dunedin. 4hrs per week for 6 weeks for $500 for all the materials and they included your own basic welding helmet and gloves!!

OK. I will see if I can dig out some photos.

I started with idea of building clock with no knowledge other than a book and no experience so some of my builds have been derailed by needing to build something else to build the original thing etc

Oh, that's standard, "I need to build the thing that I need to build the thing that I need to build the thing". There's also someone-or-other's law specifically for electronics, "Electronic test equipment breeds more electronic test equipment".

I think the same may apply for woodworking gear.

I'm sure it'll be a work of art when done:

If you want to go down a real rabbit hole, see if you can make it a mechanical Vetinari clock.

Edited to add: @freitasm, bug in the link-handling code, that link when entered using BBcode is just the right length that it soft-breaks between the end of the URL and the close tag so the HTML it gets converted into has an 0xA0 non-breaking space in it, which breaks the link.

We need a "+1 Applause" button.

Edited to add: Oh, and the tea-water(?) stain at bottom left adds that extra authenticity, although by tradition it should be brown coffee-cup circles.

Axial turner. Has expanding mandrel which you can put inside main axis of lathe and turn slowly by hand.

Hi there, sorry to bring up such an old thread but it's the only (and best) ive found when searching.

Ive recently bought a steel barn door and am planning on bluing / blackening it. After some searching I have a rough idea on what I think I need to do, but would love to get info from those that know or have done it previously.

do I need to sand 80-120 grit to remove, then acetone to clean, then use bluing liquid to cover? (I'm not sure how much I need, or the best place to get it from)

here is my door (1800mm x 2500mm)

and here is my inspiration

many thanks
