Hi Peter, I will try to explain to you through mi vague language how to proceed to do it. However, I have to say that the medium result don't justify the time that you will spend to do it. The mesh is crimped on the trumpet with ring of aluminum sheet cutted because the trumpet is made of cast aluminum and it is not easy to weld the mesh on. You need to made your own special tool (see pictures) and to use a press to bend an aluminum sheet (0.03" of thickness) like an angle ring (3/16" x 3/16"). Then, you have to cut a circle of mesh (3" of diameter) and to place it in your special tool between the angle ring and the trumpet. With a small hammer, you have to bend the angle ring to crimp the mesh below the trumpet. Then with a cutter (or better a Dremel), you cut the excess of mesh wich extends the aluminum crimped ring. This screen is not easily removable but it is possible to do it. You have just to cut the aluminum crimped ring
On the picture 1 you can see 3 Weber horn for IDF carb
- Number 1 is original made of iron sheet
- Number 2 is after market made of cast aluminum
- Number 3 is an original model that I have modified to increase the hood clearance (I have a Cobra car, not a GT40
).
On the picture 2 is the special tools you need. Internal and external diameters shall be adjusted according to the trumpet larger diameter and your aluminum sheet thickness.
My first test on picture 3 (not very nice
)
Picture 4 is my lath that I use like a press to crimp the aluminum ring
