New wings? Why? Those look pretty 'sound', certainly compared to the ones I inherited with my Long Four!

In this country at least, there is a growing interest in 'oily rag' cars - ones showing their age in a venerable way rather than being made to look like new.

Obviously the underneath is/was in a poor state, but the general impression is of a well-used car, lately neglected.

I am following your progress keenly. Keep up the good work!

Hello Ian,

... okay,
then i must repair the wings.
on the sites allround the wings, are the beading rusted through. only the fiber glas and synthetic resin filling compound belt the wings together.




original the frame was Black clarity Ral 9005 painted?
was original the frame components lacked seperate, or frame with all cross struts and wings-holding screw together an then paint?

Kind Regards marcel

Marcel,
I previously emailed you some links for taps and die suppliers. The first decision is whether you want to purchase High Speed Steel (HSS) or Carbon Steel (CS) tools. CS will not cut stainless steels or steel with a high carbon content. HSS tools are much more expensive. I think that you may be OK with CS tools on the most of the bolts and nuts on a pre-war, just take care to have the correct tapping and clearance drill sizes though, and to chamfer (taper) the starts of the threads. The Namrick taps and dies are CS but good value. I suggest you make up a set of B.S.F.Tap Set, B.S.F.Tapping Drill, B.S.F.Die for 3/16, 1/4, 5/16, 3/8 at the minimum. But I will let you know the sizes of the bolts you sent and what the threads are.

For those U bolts in question you might find it easier, based on the size of rod available in Germany, to make them to a metric thread. Not authentic I know, and may cause confusion like it has done on Peter's Javelin which has 4 different thread patterns on it!
By the way it is easy to tell the size required just measure the rod diameter and convert to fractional inches.

Also refer to this http://jowett.net/forum/viewtopic.php?f ... ner#p16103
which links to a good chart here http://www.baconsdozen.co.uk/tools/whitworth.htm

To identify a nut or bolt, as well as knowing the diameter of the rod used to make a bolt , you also need to know the pitch of the thread and then the form or shape of the thread. The latter is very difficult to determine, especially if the thread is worn and you do not have a selection of known bolts and nuts to compare against. The default on a pre-war Jowett is BSF but there may be BSW and possibly BSP and other threads may have crept in over time.

This is a good explanation of BA nuts and bolts which will have been used for the smaller fastenings.

Hello,
yesterday we phoned to "Vintage & Classic Shock Absorbers Ltd"
The man names Graham said, it gives different shock absorter in back,
1) LUVAX A, they have hole top and down and easier to become
2) the other have hole cross and are difficult to become


What are the right shock absorter for my Jowett.

In my handbook are two Detail drawn:

I I think the first Picture Shows thw right shock absorter.....

Regards marcel

[george garside]

you are right Marcel , the first picture shows the shock absorber for your Jowett. ( the other is I think for the 1931 model year)

george

[1936xxMarcelK]

Okay, thank you george!

original the frame was Black clarity Ral 9005 painted?
was original the frame components lacked seperate, or frame with all cross struts and wings-holding screw together an then paint?
It seems, the frame screws was overpaint and not silver in sight...

Does anybody know? or, how are your Frame painted?

Greetings
Marcel

[Tony Fearn]

Hello Marcel.

I would paint all the parts separately before you put them together.
When it is completely assembled, paint the completed parts once more. This should last for many years.

What is happening about the spares you requested from JCS and Keith?

Tony.

[1936xxMarcelK]

Hello Tony,

So you said, I thought also.

Was passiert über die Ersatzteile, die Sie von JCS und Keith angefordert?

In Progress


Kind Regards
Marcel

[Keith Clements]

I spent a few hours in the garage identifying the rusty nuts, bolts and washers, finding suppliers and pricing them up. Most succumbed to scrutiny with micrometer, thread gauges and dies although some of the coach bolts and very small items were beyond my archaeological skills. Has anybody a list of all the threads, bolt lengths, nut and washer types with quantities required to rebuild a pre-war? ...............

I thought not.

[ian Howell]

I ca't help directly but I seem to remember that Alan Bartlett made a similar request in the early days of his restoration. Did he (Did you Alan?) have any success / result?

[AlanBartlett]

Hello Marcel

Thanks for the PM,

I unfortunately don't have a list of the bolts required, most bolts I was able to clean up and re use, but some I did have to replace in which my option was to buy a mixed bag of whitworth BSW nuts and bolts of various lengths and sizes to replace as and if they needed. And they fitted the whitworth spaners. I bought the bag from Namrick. A company up in the midlands I think. Although not a "purist" thing to do. I was able to match lengths and sizes. Just in a different thread.

But if it does help in the back of the 1934/35 spares lists. it does list various sizes and i think lengths of the bolts. and Some bolts are part numbered as to where they are on the car. As the list does have pictures of various of the pre war car. Would you like me to scan the book? Or is on the gallery? All though it would be interesting to know how you get on with the spring shackle bolts? As I'm not sure if replacements are available. As they are not just U shape bolts but fit squarely around the spring.

Kind Regards Alan.

[Forumadmin]

Alan, Please put in Gallery and I will move to pre-war section.
Are you sure they were Whitworth? All but one of the bolts that Marcel sent me were BSF.
