BAMFORD MILLARS SV3

Hi Paul technical term would be chuck in, but it is very time consuming and must follow instructions to the letter.

The first tank I did I used your method of Citric acid inside the tank left it for a couple of days, then swilled out with pebbles and soapy water. The Por I bought a kit off e bay which included cleaner, etch, and a tin of Por, I have not had to buy anymore cleaner and etch as it can be reused, I have done 6 tanks so far and still have plenty left and have used 2 tins of Por the Bamford took quite a lot and did not put lid back on tight enough and it went off. The other tanks I made up a solution of soda crystals and water and used some bolts welded to a bent piece of pipe to fit in tanks then connected my heavy duty battery charger which is up to 24 volts at around 10 amps to do electrolysis, left for a few hrs cleaning the electrodes now and again when amps fell low, and this took out nearly all the heavy rust inside of the tank, I then filled any pinholes with fibre glass resin from the out side so that the por would then seal inside, once you have cleaned , etched and dried inside which is a must, I used a heat gun for a while just to make sure, now comes the pain bit, you pour in the Por just enough that will cover inside, what I did was keep turning tank around and around to get an even coat inside the tank, the longer you spend turning the tank the thicker the coating gets, pour excess back into the tin and make sure lid goes back on air tight, on instructions it says cannot be used again but it can which I have done, one excess has been poured out you have to keep turning the tank to keep an even coat inside as you don't want to get a build up or a puddle as they call it I must have spent an hr walking around with the tank turning every which way and checking until it finally starts to go off, then it must be left for at least 90 hrs before any fuel can be put in, as I said a bit of a pain to work with but the results are excellent, Regards Richard

Just read your comment about  POR 15.
How is it used - chuck some in the tank, swill around and pour out the excess??

You need to get the tank REALLY clean (Marine Clean from Frost's is ideal) and then thoroughly dry. A hair dryer is fine, or I just leave the tank on a radiator for a day or two. Stir the Por 15 thoroughly, block the fuel oulet, pour the tin contents in, cover the filler and swill it around rotating it at all angles for several minutes. It will start to 'go off' so pour the excess back into the tin and reseal it, it will be fine for doing another tank as long as it is sealed. The stuff sets like concrete so get any out of any tap threads etc before it sets, also it doesn't take paint well so wipe the tank dry! I then turn the tank slowly until it starts setting, then leave it for a few days or a week before fuelling it.

Thanks Gents.

Update on the SV3.
Finally got the block and piston back from Cox and Turner, only took nearly seven months, but excellent job done, liner and bored. head skimmed and new gudgeon pin made, plus new rings, now need to find time to start putting her back together again.

Bamford update, almost there just need to get flywheels sorted and painted and will be ready for its first run.

Love it! Beautiful work done!

Have to say this is a really good looking restoration - really good thread to follow - you've made it seem far too easy - but I'm sure its not

Do you mind me asking why the 7 months getting the new piston etc? - was it purely because it was low priority for them - which can be understood...if the price reflected that...

Thanks for keeping this updated - I look forward to any news on the first run.

Best of luck with that!

Hi Hamish,


I am very pleased at the way its gone back together and to be honest its a nice easy engine to work on as all the working parts are easy to get at not like some of my other engines, as for the delay in getting the block rebored and lined I was originally quoted a couple of months as told them I wanted to show it this year and was told no problem, I had no communication from then all the time they had it only when finished and the price had gone up by £ 300.00 was not happy and made my feelings felt, but cannot fault the work they did. I am trying to get the flywheels done but are taking longer than I wanted due to being 2 colours and also other things are getting in the way, but have plenty of time until next season

Think I'd be unhappy if the price went up an extra £300!!!! Nice work tho. Enjoy reading this especially as I've just got a SV!

Great thread !! Keep it going . Too many threads never have an ending and its great to see it through , well done and the work so far.

Hi Jon, Thanks for comments and have added a few more bits flywheels are a pain to do but getting there.

One of the flywheels before stripping






Next one to be prepped and painted




Painted and fitted guvnor and flywheel





Made up the fuel pipe and put a pigtail in, a tip for someone who wants to bend fuel pipe, cap off one end of pipe and fill it full of table salt then cap other end off and bend to how you want it,
the salt stops it kinking, internet is full of useful stuff if you look.

Rather than use salt use dry sand then blow it out with an air line or fix to a hose, less chance of corrosion than salt.

That Bamfords does look lovely!

Stunning restoration, cannot wait to see the end result and video, well done

Got the other flywheel painted and fitted it today and had to have a go at getting it going, after playing with the ignition timing and fuel / water leaks, also giving my arm a good work out, she runs not exactly the best place for it to run on the trailer that I use as a work bench but just could not wait to get it on firmer ground. Feeling pretty chuffed with myself after all this time getting it done, a few things to sort but that's another day.

Beautiful job - well done!

That sounds a treat!!

Thanks Paul and Villiers, must admit feeling pretty chuffed how it has gone back together and that I have got it running.

Bit of an update on SV3 have got it off the trailer at last and on a trolley of sorts which I need to source some nice wheels
I got a Bamford tool box and painted to match engine, will be on the look out for a diaphragm/sludge pump over the winter but not many come up for sale.

SV3 update, finally got around to making a trolley for it from wheels and axles had lying around, plus used the front axle from the temp trolley I put Bamford on, now need a nice day to transfer engine onto it.

Well I can finally say that this will be my last update on the SV3 as it has now been fitted to the trolley this morning,
bar a good clean and polish plus a bit of touching up of the paintwork, she is ready to be taken to her first rally.

Thanks for all the comments from you all and have enjoyed every minute of this restoration, ( bar a few mishaps that I won't
mention ) LOL
