I have one of the pressurised containers that fits onto a Schultz gun, and regularly heat it over a gas stove until the Waxoyl runs like weak tea.... someday I'm going to blow myself up but until then I can get a jet six feet long out of the gun which goes absolutely everywhere on the car that I need it to. It just needs to be kept thin and runny; once it starts to cool it's already solidifying and going to clog.
Heating over a gas stove .. are you just saying that to make me feel nervous?
-
These things are a real struggle and I have never been satisfied with the fit !
With respect to originality the mere thought of this is heresy, but..
-I have wondered.. would it possible to fabricate a metal “box” for each with a removable top panel for access to the joints and be done with the darned things?
-
Good to hear all happily resolved!
-
If the front end - carbs and union joints etc as mentioned above are OK and the smell persists..
-take a look at the back end :
-cast an eye over the top of the fuel tank. There is a small vertical pipe which is capped off with a blind ended rubber sleeve which perishes and falls to bits and can be responsible for an elusive petrol smell.If it is that there are various ways to occlude it
easiest to fit an 8mm central heating brass heating brass stop-end :

The dark bits are pitted areas that still have rust in them.
I think the active agent here is citric acid ,albeit rather expensive ,with additives to gel and keep it in place.Effective, pleasant and safe to use.
The answer is - re - application/ wire brush and just keep on going - doing it over and over again, until it looks like grey pitted metal.Then any doubt -do it again.
I tend to then apply some phosphoric acid say Jenolite, then dry it to give a dark grey protective phosphate layer - and repeat this a few times too.Dry it with a moderate hot air gun. Any trace -do it again.
It is time consuming - but persistence does pay in the end with this job.
- You’ll get there!

Rule No 1.= Rust always turns out to be more extensive than it first appears.
I have tried a few things over the years:
Hydrochloric acid
( still called muriatic acid by some)
Cheapest source - brick cleaner.
Effective. Cheap but nasty .Unpleasant to use.If you use it indoors its toxic and aggressive acid vapour will rust any of your tools within a 2 metre radius within a few hours - and make you cough and your eyes stream.Quickly flash rusts after use.
Oxalic acid.
Poisonous. Effective . Not easily available.
Citric acid.
Works both as acid and chelating agent.
The cheapest way is to buy food grade citric acid in I kg bags via Ebay. Relatively non-toxic.
Basis of Turtle Wax immersion rust remover.
Disappointing. BUT... if it is kept warm- around 36-40 C.(a brewing immersion heater is good esp. if tweaked to run a bit hotter) The results can then be very impressive indeed.
Every few hours, wire brush off the debris and reimurse
The used solution is relatively non-toxic and can be poured away into drain or garden.. The iron citrate mixture is an effective moss killer on asphalt ( it stains concrete) After use coat with the metal with phosphoric acid to prevent flash rusting.
Phosphoric acid
Can be expensive ( ie Jenolite).
Milk stone remover cheap but check as not always straight phosphoric acid these days.
Machine Mart Rust Remover is Phosphoric acid.It seems to work as well as Jenolite at a fraction of the cost.
Some lasting protection from the phosphate - use after other treatments to avoid flash rusting.
Coca-Cola contains a tiny amount of phosphoric acid, but don’t waste your time- it will disappoint as a serious rust remover.
Evaporust - Effective for immersion -but expensive. Probably a chelating agent such as EDTA.Advantages =Easy to use as probably the least toxic after citric acid.and can re-use for a few times.
Molasses - a chelating agent -effective but takes many weeks by which time it smells and looks foul.
Various vinegars -acetic acid.Can be effective - Depends on concentration.
Coatings - Those ones that turn blue are tannic acid which forms a hard coating of tannate on iron.Can work very well - but only on superficial rust .The coating has to be well applied.
Rule No. 2 = If in doubt, cut it out.

I suspect the choice of Al Zn alloys for the carb. body is more for ease of die casting rather than a choice based on its bearing characteristics.
Considering the minimal lubrication, the lack of any seals, and the reciprocating half turn action, It is surprising these “bearings” function as long as they do.

I’ve found a Wagner grease gun in an old box of tools, no idea of the model. Given it a quick clean up, emptied as much of the manky grease so now need to refill. I’m guessing this should be filled as vanadium23 post, locally the grease seems to be cartridges, is there a way of filling or am I better ordering some Castrol LM in a tub.
Ive got no instructions so any pointers what the valve on the rear does or the bolt on the top?
Exactly as Graham C says..
Like the idea of a “Wagner” gun
- stride into the garage brandishing the grease gun to the “Flight of the Valkyries” blasting forth !
Good greasings..

Paraffin and water was the method of cleaning bodywork in the earliest days of motoring when it was called “coachwork” (No, I am not that old.. ) and neat paraffin always seems to have been the thing for removing tar as it was cheap and not aggressive to the paint and gave a bit of a shine.
Remember that thick wax that covered all new cars delivered to dealers?
They used to remove it with paraffin.
A very expensive “Tar remover “ I came across some years ago smelt suspiciously like paraffin to me.

Can you have too many vices?
The best vices seem to be old, cheap and came from Sheffield.
I have just given in to a another vice. I couldn’t refuse a free Record No 34.
I already have a Record No 23 .It was my father’s and he got it second hand in the 1940s.
It works just fine.
It’s just like this one in a 1936 catalogue:
They still make one (well it looks the same )
49/- (shillings to you youngsters ) wasn’t cheap in 1936,
but now ...... £370 - and more in some places!
No wonder people buy the Chinese ones made out of cheese for a few quid..

The other year I separated “body from chassis” on a MkIV 1973 Spitfire.
I know it had not been off before, so what was found was original:
The whole of the underside was in body colour apart from attached components which where in black.
It would seem that the chassis was sprayed black before being united with the body in primer and then both sprayed in body colour.
The evidence for this is that parts of the chassis had had escaped the body colour spray (because it was up against body ) were found to be still in black; the corresponding part of the body covered by parts of the chassis were still in primer.

The filling process of most grease guns is primitive , fiddly, time consuming and extremely messy.
Wanner has a floating plunger device that allows filling by pressing the body of the gun down over the hole in the plastic cover that sits on top of the grease in standard grease tub(1)
Fills it in about a second -no mess(2)

If you like fascinating odd patents and inventions - (and If you have’t heard of him)
I suggest looking up the inventions of Granville Bradshaw.
The (flawed ) genius of aero engine, ABC cars and motorbikes. toroidal engines designs also 3 D television and security devices andeven lots of patents for slot machines.
-
Yes, they do seem to be around sometimes on EBay as you noted ,Steve.
Useful yesterday recovering a 1/4” BSF bolt on something very old.
They aren’t as ancient as I thought.
Lawrence Edward Lamude got his patent in 1953.
-Younger than me.
-
I can’t remember when I got this device - and it was ancient then.
Just used it successfully and mention it here as a curio
It does work surprisingly well
I wish I had one in other than BSF which I don’t encounter too much these days.
Can you get them in UNF / Metric or is it from a by- gone age ?
-
Agree re Wanner 315.Bought my original in late 60’s ,I think.
More recently, got 2 others on Ebay (for different jobs ) for about 12 quid each.
They are easy to fill and work perfectly; they don’t leak everywhere - even with oil.

V23-Thanks for the post. I am shortly going to start work on paint stripping (starchem paint stripper) and your post has been invaluable to me. Are any of the vapour filters of any use in a 3m 6200 mask or is it just a question of doors open, restricted time using or just, as you mentioned, an outside job for safety?
I really am not knowledgable enough about mask specifications - or bold enough to say that a certain mask would provide adequate safety ,Mr Badwolf.
Fresh air, outdoors is best.

Your right about the atomic number.
Sorry to disappoint, but is nothing remotely clever, subtle or imaginative in my choice of the element.
It has nothing to do with the colourful compounds of this transition metal or links to the Scadanavium goddess Vanadis aka Freyja and any Manx norse connections.
Rather boring, really .My limited brain capacity was fully saturated at the time reading about early motor cars and car metallurgy relating to the French use of Vanadium , Delage cars and others, and the subsequent use of Vanadium steel by Henry Ford in his cars.It left no room for anything else to “spring “ to mind.
Further reading went on to the other elements used in steel production and the mysterious cloak and dagger WW1 story of how element Mo atomic No 42 came into use in steel alloys in the Great War.
(I could have used that -but it is more difficult to spell)
Best Wishes,
- I also answer to Andrew

Brake fluid only works well as a paint remover where you don’t want it to!
The “ Good Old” Nitromors used to contain methylene dichloride aka dichloromethane - which is a brilliant paint stripper.
Its availability has been restricted for some years now.
The risk to people with some basic awareness of how to use it is probably close to zilch.
But.. it can be really nasty stuff.
Gloves certainly as it burns and you can absorb it through the skin..
The big risk is from inhaling it.
It doesn’t smell much or that bad -it is very rapidly and easily absorbed. and affects the nervous system with both short term and long term effects but the immediate danger can be from carbon monoxide poisoning.
The readily absorbed dicholoromethane is metabolised to carbon monoxide which as everyone knows is highly toxic as it competes for and displaces oxygen carraige in your blood -which is not a good thing.This is especially so if your arteries are a bit narrowed.
Really good ventilation is essential. Not just a mask (depending on type it may be quite useless in this situation)
- a really good flow of fresh air is what is required
I happily use dichloromethane
- outdoors.

Mine's booked in for Monday. In a chance conversion about the weather when I booked it, I mentioned that I needed to refit my sun visors. He said you need to because it's an mot failure not to have any.
I've never heard of it before (not surprising really) and I've never seen it on any check lists.
Was he pulling my leg?
Sadly , probably not.
Lives are lost and tragically ruined in accidents.
But in so many areas of life ,bureaucratic nonsense insinuates itself into our lives so that much time and effort is sacrificed on the pious alter of “Better Safe than Sorry” , MOT is one.
Road safety would be just as well, if better served if a driver was prevented from driving after an emotional conflict where there is dangerous distraction caused by marital ,financial or work worries. Very loud aggressive rock music, or even having certain meals can apparently be risky.
It would be impracticable -as would sifting out those with a personality trait tending towards reflex and mindless aggression that results in them driving with self rightous and murderous vengefulness, but it would yield better results than triumphantly detecting an extra thou.of play in a wheel bearing, a scratch on a windcreen or a wobbly sun visor.
Very few accidents are related to a mechanical problems (unless you include the oft-quoted problem with the nut that holds the steering wheel).

I had forgotten that the “New Pence” coinage was introduced so much in advance of the actual ”Decimilisation Day “, if that is how it was spelt.
Some folk were quite put out by it.
There was a lady interviewed in the street ( probably Fife Robinson on the “Tonight” programme) who thought it would be better “To delay it - at least until all the old people had died”.
-
Well it’s lasted OK!
- if the date is 1968 then you also have something a bit special.
My vague memory recalls all the fuss when decimalisation came in.
I am pretty sure it was sometime in 1971.

Recently, I have been looking at Waxoyl alternatives:
I bought two aerosols with extensions -just for small jobs and was surprised how effective they were.
The Kent wax and the Indasa have a Dinitrol type smell,( not like the white spirit smell with Waxoyl) and is more like Dinitrol in consistency.
Kent also do a can for use with a a shultz gun and compressor - £9.05
My gun and probe made by Plastic Padding years ago -and have been refilling the container with Waxoyl.
