Metal question

After years of an outdoor lamp malingering in the back (communal) garden I've decided to try and refurb it
It has a glass surround which takes a hefty candle and has a generous carrying handle.

It's rusty as hell so I've ordered Evaporust, something I've been meaning to get hold of for a while and looking for an excuse Saw it working originally on a restoration channel called Hand Tool Rescue, and I've even got a couple of the wrenches this chap has made. I think it's a hoot as well as looking at impressive skills (to me!)

One part of the lamp which has pretty well crumbled is a sort of mantle - ok it's a perforated cylinder 45mm diameter and 50mm high with 5mm holes which is welded (brazed?) onto a covering cap which sits on top of the glass.

Bits have already fallen off this so I'm attempting to source a replacement without going into silly money. I've found a perforated steel tube but it's 50.8mm diameter and 1.6mm thick - the original is probably only 0.5mm.

Maybe I should get a flat piece of perforated (?mild) steel and form it into a cylinder....

Then I have to find someone to assemble it

Any suggestions please?

Hi Simon, I have the very stuff in my shed that may suit your needs. Stainless steel perforated flat sheet left over from my welding days in the oil yards. I never throw anything away PM me and I may be able to help.

Wow Jim that's quick!

Do you reckon this thing might be brazed?

The sheet needs to be able to form easily so not too thick!

It’s not too thick Simon . All you need to do is form the sheet around something rounded the size that’s required, now welding stainless is another mater, but you may be able to jam the cylinder in the hole.

45mm = 1 & 3/4" so should be able to get suitabler exhaust silencer parts.

look similar.

Right.

There are two rings at top and bottom which seem to sit "inside" the cylinder, possibly to attaching to the cap above.

I'm spoilt for choice! These didn't appear in my searches

Am I justified in thinking that the original metal has degraded such that it has thinned down to around 0.5mm, i.e. it was originally thicker?

The "weld" used to fasten these parts together is brassy in colour unlike the steel being joined.

Anyone know what technique might have been used?

Sounds like it's been brazed Simon.

That’s been brazed as Joe has said Simon.

Cheers chaps, will definitely be farming this job out!

Easy job Simon, but you need the equipment.

Mrs Ed... "where are you going to keep that"

Not that large Simon, I braze with just a propane torch, No oxygen cylinders needed.

I use something like this but older.

it screws onto a propane or propane/mapp canister.

There's a whole metal world out there beyond Slipknot...

If you have a blow torch similar to the one Pete uses you could also lead solder the two pieces together.

Well as it happens I'm negotiating getting perhaps one of these Rothenberger jobs for my recent birthday..

("where are you going to put that" )

That's looks like the perfect piece of kit just for the job

Hi Simon how are things going on your project?

Funny you should ask Jim, very well in fact as I just got it back from being brazed late yesterday evening!

A chap who did my yellow camcover/black plug cover years ago is still operating and sorted it for pennies

Thanks for all the advice and to Jim for supplying material

I'll post a pic later....

Great stuff Simon.

That looks really smart Simon. In the words of the song.........You light up my life, you make me feel brand new.

Ooh steady on you two, sounds like a bit of man-love going on there

Simon can we have some action pics of it in use?

That's an impressive light, hope it's hung somewhere safe.

Yeah, I've asked the same brazing chap to fashion a forward-mounted pole for BumbleBee for it to hang from to see in the dark a bit better

Have to admit I needed to read it twice before giving it the benefit of the doubt



Like, lamping someone?





(translate that, southerners )

Erm, it was from the lamps point of view.....
