A few weeks back I acquired three spare Minor wheels from a member of another forum, and over the past week or so have made a start on restoring them. First job was to take the tyres off - I tried to do this myself, and successfully got one "side" off, but completely failed to get the other side off. So I then tried cutting them off with an angle grinder, but after filling the workshop with rubber smoke and still failing, I took them to the local tyre fitters who removed them for £1 each! Much easier :D

Here they are before restoration:

Image

When starting to restore seriously rusty items, one of my favourite tools is this air-driven needle-scaler. It has 30 or so needles which vibrate vigorously like a pneumatic drill, and "chip" loose rust off. Here is the tool and one of the wheels - I have just made a start on this wheel, but a long way to go!

Image

Using the needle scaler took quite a long time, but worked well, here is the top and bottom of the wheel after "needle scaling":

Image

Image

Next I cleaned it up some more with various wire brushes etc. on both drills and angle-grinders, and removed the rest of the surface rust and paint.

I ordered a number of interesting rust-related products from Bilt-Hamber, as I have heard a lot of good reports, and wanted to try them out. One of these is the Deox-C crystals, that you dissolve in water to form a de-rusting bath solution. I bought a large flexible bucket for £10 from B&Q, made up the solution in a 25litre drum, and poured it into the bucket. Here is the wheel just after I put it in the bath:

Image

This stayed in the bath for two days, then today I took it out, rinsed it off, dried it and went over it again with a nylon cup-brush in a drill to brighten the steel up - here is the result:

Image

I then painted this with etch primer, but unfortunately when it was hanging up being painted, it fell on the floor and dented the rim. I think I will be able to bash the dent out, so I will do this when it is dry and re-paint it in primer - photos to follow!

I then made a start on the next wheel. This time I've decided to let the Deox-C bath do more of the work, so here is the back of the wheel after needle-scaling, although this time I only went over it quickly to get the worst off - as you can see it's still very rusty, we'll see how the bath copes with that!

Image

In order for the bath to do its job, all the paint has to be off the wheel first of course. This time I decided to try Nitromors paint stripper. I spent several hours this afternoon working with this horrible sludgy stuff, and the photo shows how far I got after rinsing it off the wheel - not a very good result! I'm going to give up on the paint stripper and go back to taking the maint off mechanically - I'm sure it will be more thorough and quicker in the long run.

Image

Still a long way to go - more to come!

Love all your posts Luxo... Makes me feel like I'm there with you :-) Good work and some good tips too, Thanks

I have heard good reports before of Bilt-Hamber, nice work.

I like the needle scaler - what sort of PSI do you need to run it?

Wow I can only dream of getting round to doing these jobs! I am really pleased with your wheels tips though - seven old rusty wheels came with mine so I will follow your lead, keep the best 5 and give away the other 2!

Just one rcommendation, i took mine to the sand blasters and they did a really good job then quickly painted them with primer to avoid re rusting. Here it only cost £15

Thanks chaps - yes, I did think of taking it to a place to have them blasted, however I don't know of one round here, I may have to do some investigation. Still, this way I get the satisfaction of doing it all myself!

Yeah, it's a great tool for this sort of thing, I think I got it from Machine Mart. I run it at full chat - 150 PSI, but my compressor is getting a bit tired so this soon drops to about 70 - 80 PSI, it still works very well like this. Uses a fair bit of air, so it would struggle on a small compressor I think, OK on a big-ish one.

Cheers! :D

Well today I got a suitable heavy flat dolly and large "Manchester spanner" and beat the wheel back into shape where it got bent after dropping on the floor - offered it up to a non-bent one and it looks pretty much perfect to me, so I re-did the damaged primer and here it is in the boiler room drying off:

Image

When I get a chance I think I might lift one rear wheel on the moggie, fit these spare wheels and start the car in gear. This will spin the "test" wheel on the car, and I can check if they are bent, out-of-true etc. before I go any further, in case any are actually scrap!

The second wheel I attacked with sanding disks and wire brushes to "mechanically" remove the rest of the paint, and got it good enough to go for a bath - here it is in the Deox-C bath today:

Image

I won't have a chance to do any more work for a few days so it will have a nice long time to soak, and we'll see how the Bilt-Hamber stuff copes with this amount of rust - there's a lot on this wheel, it will be quite a challenge! We shall see...

More anon! :D :D

I might invest in one then, my compressor can handle 80PSI - like yours though its also a bit tired - it was made in 1961! A classic compressor to go with my classic car :)

It'll keep working then.. unlike the modern compressors!

Exactly! Mine is a direct-drive modern type one, and seems to have a relatively limited life - I'll be looking for a decent belt-drive one before too long I think. I find once you have a comressor, you find more and more uses for it, I wouldn't be without mine now.

Cheers :D :D

I miss mine.. I had to leave it behind when I moved :(

I got mine from a friend, its an Ingersoll Rand, belt driven type and very quiet running. I also have a little 6 litre bandit compressor that I got as part of a nail gun kit and its very noisy.

Belt driven is quieter, but more bulky. Problem with older ones is that you don't know its history, has it been dried out regularly?

Back to Luxo's marvellous resto now though :)

I have moved this so it has its own title.
Excellent work Rick.

Hi luxobarge, out of interest how much did the bilt-hamber stuff cost? I'm busy de-rusting some stuff in the same size tub you have but following the recent article in Practical Classics! It cost me £2.00 for the soda crystals! Granted you need a few scrap bits of steel and a battery charger but I'm seeing the same sort of results you have in your photos. I took the easy way out and had my wheels sand-blasted and etch primed £10.00 from my local guy. Keep up the good work, enjoyng your Pictorials!! Cheers, Croft

Hi, it cost £22.70 + P&P for 2 kg - I'm using all of the 2kg in that tub. So, not particularly cheap, no! I also bought some Deox-C gel, for parts that you can't submerge in a bath, but I haven't used that yet.

They have an interesting website - here's the link to the Deox-C page:

http://www.bilthamber.com/deoxc.html

Interesting what you say about the electrolysis method, I might give that a try another day. Where did you get the soda crystals from?

The second very rusty wheel has now been in the "bath" for 2 days and isn't showing much sign of improvement, but to be fair they do make it clear that the reaction is much slower in low temperatures, as you'd expect, and it's pretty darn cold (like 5-8 degrees) in my workshop right now! 8)

Soda cristals came from my local hardware store, £1.00 per 1kg! and you use 10g per 1ltr of water. If you havent already read the article, its in the November issue of P.C. Seems to be working very well for me!

Cool - thanks for that. I've been getting PC for years (I'm a mod on their chat forum too) but after they messed up my subscription, the November issue's the only one I haven't got :roll: Still, I get the general idea - as I say, I might give that a try in the future, may even do it quite soon if the Deox-C doesn't work, especially as it sounds a lot cheaper!

Cheers :D
