Author Topic: Small (~5cm diameter) brass portholes?  (Read 2229 times)

So, I am both a bit of a steampunk fanatic and a bit of a gamer. My friends know this, so when my birthday came around, a friend bought me a set of metal dice, and gifted them to me in a small wooden box.

But this wooden box... it's just ever so plain. His intent, I believe.

I've got my designs mostly down, but I've hit one problem - I really want a green glass window onto the inside. The green is easy enough - plexiglass is easy to find at reasonable prices. It's the frame that I'm having trouble finding. I'd love some sort of brass porthole style thing, but it's nigh on impossible finding ones that are small enough (the box itself is only about 7cm wide, so I'd need something with a diameter of about 5cm).

So my question is this - have any of you seen anything that looks remotely like it would be helpful? I'd prefer real metal (nothing beats that cold to the touch feel), but I'm open to suggestions.

Have you tried adapting metal curtain eyelets? Not sure how you would do it, but they may be avaliable in about the right size.

How about washers? Most likely to find steel ones.

washers and eyelets are the same thing (I think, could be wrong), its the Brit/American language thing again Tongue

Strictly speaking, washers and eyelets are two entirely different beasts. A washer is a spacer for nuts and bolts and an eyelet protects a hole in fabric from fraying.

Failing finding anything suitable, might I suggest getting some sheet brass and making one yourself? It's not actually as hard as one might think if you get thin enough brass which can be cut using household shears

I'd say brass washers were the way forward.

I'd be looking for 2 washers with an outer diameter of 5cm and an inner diameter of 4 cm.
Then another washer with an outer of 5cm and an inner of 4.5cm,

Put them all on top of each other and drill 4 small holes at even distances around.
Put one big washer inside, and run some small bolts through.
Put the narrower washer on the outside and put a 4.5cm disk of green plexiglass into it.
Then put the last big washer on which will hold the plexiglass in place.
Fix nuts onto the bolts.
Job Done.

For washers that big (or close to it) check out the plumbing department of your local hardware store.

Och Aye! Such a simple question for someone with wee puffer for an avatar, and there is your first hint. I made the ones on the puffer on a lathe , (aboot 20mm)  but there are brass port holes available from model ship suppliers. Even wee working portholes. I'm not sure what sizes are available though , You are in luck being in the UK there are several good sources there.A couple that come to mind are Scoonie hobbies in Scotland, and Westborne models. there are quite a few others.

I imagine that you could achieve some success in this by getting some cheap tin snips and some copper flashing. You could cut the portholes to whatever size you want and tack it down with some brass or copper brads to look like rivets. You could also give 1/2" copper pipe and fittings a try.

I've used clock bezels for similar things.

Heres an example from the first random google search I tried.
Cheaper examples are available.
