Hints and Tips - A7 Bonnet Fit

Subject: A7 Bonnets

My first contribution to the list, but given all the A7 mails I thought someone might be able to help me:

I am in the process of building an A7 Chummy from a pile of bits and a second hand replica body. I have run into a problem with the bonnet I have, being too wide for both the scuttle and rad shell. Looking in the books, the body appears to be a 1927 AD type. Was this built with different width scuttles, or is the bonnet I have obtained from a different model car?

Any suggestions on where to get one that fits?

I couldn't comment directly on your car or the body you have with it or even the bonnet come to that! However, three things strike me. First, if you have access to another car you believe to be the same model, ask nicely and borrow the bonnet and see if it fits (your car to be known as Cinderella for ever more!). Ask nicely and see if your bonnet fits on other cars of known body type. Finally, if the bonnet is oversize in terms of width (as I understand it), disassemble it in the top hinge area and cut down the top pieces to fit.

Where to get another? Well, depends where you are in the country. There are various ports of call; John Heath, Keith Roche etc. No personal experience, but they all seem to have a reasonable reputation. If you choose to get a new one made, mount the body and rad, then take the car to whoever and get one made to fit. Shouldn't cost anymore than just 'ordering' one, and then at least you have a guarentee of a good fit.

Hope that helps.

Tell us more about the car

Hugh,

I thought about cutting a piece out of the center but the problem is that the curvature of the bonnet over the edges of the scuttle and rad shell are also incorrect (to large a radius) and modifying those is not so easy. The bonnet is a new one, very nicely made so it seems a shame to chop it about if it is correct for a different model and may be of use to someone else. I have not got the valance panel or rad shell assembled to the body yet, so If I got another bonnet I could probably build the rest around it which may be easier than trying to transport the rest of the car to someone else!

There're a Bristol A7 Club meeting coming up so I may take it along and see if anyone there can identify it.

The car is short chassis that I dragged out of an orchard in Essex 10 years ago and have been collecting bits to build up since. The body was a second hand replica (unused but rusty from sitting around) that I picked up at an Autojumble.

I assume that you are trying to build a 1927/28 Chummy with a short radiator. I have just taken some measurements from a 1928 Top Hat saloon, and the radiator is 17 in wide, the bonnet is 17.25 in long at the hinge and the scuttle is 26.5 in wide (all measurements approx).

What are the measurements of the bonnet that you have? It might be a good idea to check that that the body you have is reasonably accurate as well, although it is unlikely that the radiator cowl is wrong (however there were at least three different sizes pre-1930).

You are not a million miles from the Austineers in Bradford upon Avon. A quick trip (c. 40 minutes from work) could answer your questions.

Good luck ! David Cochrane (1925 Chummy & building a 1928 G.E. Cup Special)

David, Yes I am trying to build a '27 car with a short (painted) rad. I measured my scuttle and rad shell and the dimensions are as per yours below (thanks). The bonnet I have however, would suit a scuttle two inches wider (same length though). Looking through the A7 source book last night, I noticed there is a reference on p180 to the 1928 AD tourer being revised with a wider scuttle and higher rad, so maybe this is the model my bonnet would suit? Presumably this means there are actually two versions of the AD tourer?

The variety of models makes it very interesting, and very frustrating trying to assemble a car from a collection of parts esp when, like me, you are new to A7s!

I have spoken to David at the Austineers before and he helped me with some chassis work. I have only just encountered the bonnet problem as the assembly is progressing, so maybe I am due another trip down there.

Pete,

Yesterday, I came across this quote from Keith Roach's price list. They can supply 4-piece bonnets 1926-30.

"N.B. We will only supply bonnets if we fit them to the car in our workshop."

It might be worth giving them a call (01703 814287).

Good luck! David.
