The Ultimate FC

For something that was designed in 1960 the Alvis Stalwart is very futuristic for its age.
It always reminds me of the Thunderbird kids show which I enjoyed very much as a kid and one of those scenes where the special purpose truck or vehicle is on the narrow road with the road way slowly giving way to a deep drop to the valley below.
Below are some Stalwarts converted for movie or advertising work.

Another progress report.
I have now lost the good weather of working on the stalwart thanks to winter.
The tail gate is now back with another alloy square tube welded to its lower edge and then repainted etc.
A new rubber seal has been fitted to the tailgate.......a long slow job.
The space between the double hull where the exhaust system runs though the hull has painted in high temp paint and then red oxide........another long slow job working though a small hole.
Still chasing rust .......now just forward of the muffler box.
Muffler box is now painted inside and out and again high temp stove paint where needed.
I need to find a way of bending a radius , leg out into stainless steel angle.
Been looking into making some sort of rolling machine using forklift mast rollers.
I expect there will be a unwanted secondary bend induced some how.......any ideas in a better way of doing it with the brains trust.

The pic above is where I need the bent stainless steel angle.




Some more old Pics of stalwarts.........in Singapore ??????

Just one more pic
I am improving sealing on the exhaust system though the hull by using high temp fibre glass rope and high temp glue instead of metal to metal with gaps and It should reduce the stalwarts habit of doing a big back fire every now and then.

Ron if I understand correctly you need a fixed former the diam of the bend you need and a roller pivoted in the center that follows your former around .Just clamp the end of work and pull your roller round

An engineering shop with a rolling gear will be able to roll the angle toe out for you. The mob I worked for 35 years ago(now gone), could do that sort of stuff. An enquiry at any engineering shop will probably get you the details of someone who can do it if they can't.

Yeah that could work and simple to make.
I have been doing a little bit of research into this.......one problem I will have is it will not bend cleanly and the angle tends to twist.
Checking out machines that bend angle iron, usually have secondary rollers set up to slightly twist the angle in another plane as the main bend is being put in.
Just thinking with the above set up.......may be if the roller going over the former had a 2mm slot in it to keep the angled stainless steel straight?????????

I seriously looked into a proper roller bending machine from Machinery Warehouse......out of my reach currently and hard to justify the expense when I would only need to bend about three pieces.
In Nowra I have so far only located one roller bender machine and getting the bend just right when the job is off site would be hard.

As long as your following roller is a tight fit on both legs I think you will be happy I built a set up to bend my yacht port hole frames out off 1x1/4" 316 ss angle with the leg in it took abit of stuffing around getting the right profile on the formers due to the fillit on the inside of the angle but worked out perfect in the end .Pic of1x1/8"gal angle leg out used for inside furniture framing

The cheap way to bend the angle, is to stretch the flange in your photo - which sits against the body - on an anvil using a stretching hammer. If you don't have a stretching hammer, a cross-pein woodwork hammer works well. Being stainless, it will take a fair bit of hammering, but it will bend. It may need to be heated to red heat occasionally to stop it cracking, but this depends on the alloy being used.

Have a look on Youtube for, stretching a flange with a hammer,
