Engine bay painted by Keith  (October 26th, 2008)
Done - Engine bay is now painted with top coat. I have put on what I think is the minimum of 4 coats (although some is thinner). The final finish is ok with a little orange peel in some areas that are difficult to cover without over spraying. The minimum of cutting back would give a good finish but I probably won't do that for now.
Amazing how those ellusive dents seem to jump out once there is a shiny finish on it. However once the Engine bay is filled with engine bits and dirt then paint and other faults will go un-noticed and we will think "was it worth the effort?"!!
Let's strip off (the engine bay!) by Keith  (October 7th, 2008)
Paint stripping started, unfortunately not far enough due to bad weather and the delays caused by disc brake conversion problems.
Lots of hard work stripping the paint but finally got to the metal. The rust was tackled with the wire cup brush on the angle grinder and the metal scuffed up with a surface prep disc on the angle grinder. This disc is a kind of hard scourer thing which gets of any odd stuff and sands the surface to about P180. I then went over the metal with P320. Although where the wire cup brush had scratched the surface I had to use P120 first. Avoid the cup brush on good metal as it does more damage than good.
The zinc primer didn't spray out my old gun, I guess because it was not thinned out as much as normal. The old gun has no pattern adjust. The new DeVilbiss sprayed it fairly well but caused a lot of atomisation and mist even with the presure down and the needle out to max (to the point where the knob fell off! :hehe. Hopefully with the filler primer and top coat it will be better.
I now need to seam seal and touch in a few bits that were difficult to reach with such a large gun.
Touchdown by Keith  (September 29th, 2008)
After a bit of a delay while I sorted out the front disc brake Marina hub conversion (see this article on the whole experience) I now have wheels on each corner.
The Mog is now off the roasting spit and on it wheels.
(Obviously the picture needs turning but my software messed it up and I lost the original picture.)
Suspension - one corner ! by Keith  (August 18th, 2008)
Getting round to adding more bits to the Mog. Here is the front offside suspension (less hub - see elsewhere for details).
I put back the steering rack, master cylinder, fuel and brake pipe that run underneath.
Not sure if I got the ride height correct but it is close to what it was before so should only need fine adjustment with the rear adjuster plate.
The poly bushes for the eye bolt went in ok - although they still get squashed a lot so I added a washer between the arms (you can just see it in the picture).
When fitting the bushes it is easy to get the front one squashed to much. This is because the rear arm slides down the splines and so to bring the arms together the front one squashes.
Normal advice is to remove the tension on the arms, however this doesn't really work that well as the arm often will not slide on the splines (even a nice clean one like this didn't). My advice is to help it slide forward using a block of wood and hammer
Other advice is to tighten it down when the suspension is under load to stop the rubber bushes tearing. This helps for rubber bushes but is not required here (hopefully) as the poly bushes can be greased so the pin will slip round freely.
Morris to Marina disc conversion by Keith  (July 31st, 2008)
The Morris I bought for parts for this project had a tuned 1275 engine and disc brakes. I assumed the previous owner had down the work and I only had to use the bits. Unfortunately, the person had just put the Marina hub with Marina bearings onto the Minor axle. Then tightened the nut to prevent the loose fitting bearings wobbling.
So what I was expecting to be a hub conversion was nothing more than a bodge. Consequently I had to get the conversion, which proved not much better that the solution without it.
The whole experience is described here .
Suspension by Keith  (July 29th, 2008)
Picture shows the first bit going back on the car (not my hand!). It's the eye bolt - soon to be fitted with poly bushes.
Now in the stage of cleaning of some remaining suspension bits. I had not previously done the dampers as I was going to use the telescopic shocks that I had. I may still do that on the rear if we keep the car, current talk of changing it for a traveller
I want to get it on the wheels, hence get the suspension back so I can strip the paint. Undecided whether to just strip everything or do the front first followed by the rear. Garage is to small to get round the whole car for spraying.
Note to self: get a bigger garage - a single one is hard work
Gravitex finish - the verdict by Keith  (June 23rd, 2008)
I used a Schwartz type underseal gun to apply the Gravitex. Gravitex is made by U-Pol and seems to be hard to find but I got mine on line from Auto Paint and Panel although postage is a bit steep.
The Gravitex is cellulose based and dries very fast. To get an original looking finish I set my gun to about 60psi and tried to get a thick coating on in not to many sweeps of the gun. Overspray gives a sandpaper finish but luckily due to its consistency you don't get much.
It covers over the original stonechip finish but I tried to cover some old oil based underseal which although it seemed ok in my tests didn't quite work. I think was due to the thickness I applied, some thinner coatings applied a few times would cover it but wasn't that great - better to remove all traces of oil based underseal.
I also found that the seam sealer would have been best primed before applying the Gravitex as it lifted off in one or two of the corners.
I bought some more Gravitex so that I can complete the fixes. I used 4ltrs of the stuff to cover the cills and wheel arches. I didn't cover the centre from the cross member backwards (basically the propshaft area). I guess that would take another 1ltr.
So, some areas to fix due to inexperience but generally this is looking like good stuff. As an update I cleaned off the area that had the underseal and resprayed the Gravitex but the new bottles were thinner and gave a smooth finish. Sod's law isn't it - when you want orange peal finish you can't get it
So just in case you're trying to do a similar thing then 6ltrs should give a good coating over the underside and inner wing wheel arches (as in the picture, not inside the outer wing). Also, for good adhesion you need to give the metal a good key, I used one of those surface prep (0.5" hard pot scourer type thing) disks for the angle grinder - however I didn't do all the surface; bit of a rush to get the stuff on and I forgot
Oh, and for the record this is the black colour, the pictures are taken with flash so its looks a bit lighter.
Primed and seam sealed by Keith  (June 6th, 2008)
Following all the underside welding, I cleaned off the welds and any surface rust, wiped down with some de-greaser and primed the bare areas using etch primer from a can.
The seams were then seam sealed and a few little surface areas filled with body filler.
I decided to clean off the seams in the engine bay because I wanted to underseal the bottom of the car whilst it was on the 'roasting spit'. However, I also wanted to paint strip the old paint in the engine bay as previous resprays had left a thick amount of paint that would not be a good base for yet another respray. The problem here is that the paint stripper has to be washed off and thus the car out of the garage. So the only way to prevent paint stripper and water going down the seams was to clean and prepare them now.
I'm finally getting to the part where things start taking shape. The cleaning off, welding and making panels seemed to be never ending.
Nearly the last bits of underside welding by Keith  (June 6th, 2008)
See these few pictures of the near side repairs. New cross member end added, inner cill floor and outer front cill floor, plus the ends by the rear wheel arch. Numerous other little repairs.
The remaining rust you can see is surface, except the area in the floor under the exhaust heat protector, which is a bit of a water/rust trap.
Whilst cleaning off with the wire brush on the angle grinder I made a hole as what I though was surface rust disintegrated.
Much of the cleaning off has been with the angle grinder plus wire brush; prior to that I got rid of old underseal using a paint scraper and old oil with white spirit.
The areas of sound body with sound underseal I ran over lightly with the angle grinder brush to get rid of the dusty dry surface and provide a key for the Gravitex.
Progress by Keith  (May 15th, 2008)
If anyone is actually reading this then I have been progressing quite well, just not updating the journal.
Almost done the underside welding and at the cleaning off the odd bits of surface rust and old underseal / paint.
Unfortunately located another lacy bit on the rear wheel arch so will have to cut and insert a section.
For cleaning off the the welds / underseal / paint I've been scraping with an old paint scraper, then using the wire brush on the angle grinder. The flat version is better than the cup for all the corners.
The intention is to clean off loose bits and welds and prime with spray can etch primer. Then use the Gravitex stonechip to underseal. The Gravitex is supposed to be able to cover anything and also be overpainted. The old underseal is oil based stuff and goes soft with the Gravitex which is cellulose based. On my test area it didn't react and went hard again after a week. Hopefully a larger area will do the same - we shall see
