My rad expansion pot.

It's not finished yet, but it is the first thing I've ever made (welded) from sheet ally.

I think I'll hide it under the nose cone.

I think it looks fine

Looks great to me, I,d cut a hole so people can admire it

Where did you get the filler, its one of my next tasks.

Regards Mark

are you gonna start knocking oil catch tanks out? looks spot on to me.

looked soooooooh good posted twice

O Mark. Mark, Mark, Mark.

O ye of little faith.





It's a piece of sheet, 152 mm long.

G clamp over an edge of plate, with a plate on top, 3 mm protruding, and knock it down with a nylon mallet.
Remove clamps and knock to 180 deg safe edge.

Same again with 4.5 sticking out.

You end up with a double bend, three thicknesses of material, 5.5 deep.

Roll round a piece of bar or pipe, weld seam, and file out two slots.

Cut tube to length, to fit rad cap, in this case 19 mm, and you have a filler neck.



Scratch building to the extreme me thinks.

Nice Job...What type of welder are you using? MIG, TIG, Gas?

Do you mind giving out the model mumber?

If I'd made a piece that nice, I'd put it on display in my living room!! Lovely piece of kit, be proud of it!! Wish I knew how to TIG

Good to see your 'practicing' in anticipation of my request for swirl pot

looking good, yet again your hand skills put us mere mortals to shame!

Hi Paul

I know in some circles it is considered bad form to ask a cook for a recipe and I hope you will not be offended if I could ask you for a bit more information on how you made the very nice header tank. I am particularly interested in how you rolled the aluminium neck for the radiator cap. A superb piece of work that will really enhance your car.

Best wishes

John

Nice one Paul but you will have to polish it before it gets anywhere near your car . Can I ask how the gas welding is going?

Hi Paul good to see some nice work going on cant wait to see your nose cone. regards Trev.

Hi All,

Thanks for the replies.

In answer to your questions......

dl-peabody, used a miller dynasty tig welder.

Tim & Dave, What's a catch tank or a swirl pot?
Is it like a keep net or a guzunder?

John, see post 7, back a page.

Rusty, I think an inlet pipe would be handy. I just knew I'd forget something,
and NO, you may not ask about my gas welding.

Trev, the nose is an August job, (and Sept, Oct, Nov, Dec, etc, etc)

I bought my ac tig so I could "have a go" at something I'd never done before, i.e. aluminium sheet metal work.
Hi Paul

Ignoring the above, it really is a fine piece of work and anyone who can TIG weld aluminium will agree. A T weld (to me anyway) is the hardest weld to achieve. It is so easy to burn through the edge of the vertical.

The maxim I try to apply is, if it is the best that I can do, irrespective of what others can do, it is ok. If it is not my best, then I bite the bullet and remake it. I can then look at the job and know that it was the best I could do. There, thought for the day!!

John

Only joking Paul, I've just completed two years of the ABC welding courses, so I know how difficult it is to weld ally. It looks bloody good to me!
When I said 'NICE ONE', I meant it!
Keep up the good work!!!
Cheers John

Paul what gauge aluminium did you use?

John

It's 16g John.


The ends I "pushed" round a former in the lathe.

It's been mounted now, , on a cross brace just in front of the thermostat housing.
Although it's far from perfect, it will be nice to look back and say, "that was the first bit of ally I made".
