hello

stuck ( massa plastica in portuguese ) is applied on all the surface of the horn.

http://www.crayvalley.com.br/produto...produtos.php#5

we use two different kinds of stuck. since we use brazilian products, you will have to find the equivalent in the u.k. If you go to a car painter, he will be able to give you the right information of what products to use. no mdf layers will remain visible:

after that comes grinding , up until the wanted profile with close tolerance is achieved :

with a mold you can check if the profile is according to the drawing.
i have used a wood mold, but the best is a thin metal sheet of about 2mm, which you cut to have the exact negative of the horn flare. This alouds to get a high precision of > 1mm .

after that you use primer, and finally comes painting. There are horns, i made more than 6 month back, and these continue perfect.
It is important as well that you use wood sticks to fix the mdf layers together, so that these won't move and change position with time :

Did not realize these were so large. Or is the person standing beside it small?

"bondo" is a generic name in US for common two-part plastic auto body filler.

Many thanks for the info - and again, the horns look great.

Surely you must have to put quite a thick layer of the filler onto the MDF, otherwise it would just crack and fall off?

There have been discussions on sealing MDF here before, and someone mentioned that these fillers don't tend to work well on MDF. The reason is because MDF absorbs one of the chemicals in the filler, so the filler doesn't properly cure. However, if you've got horns that are perfect after 6 months, it must be OK.

I've used auto fillers on MDF to cover nails and other imperfections, but I've never spread it onto a smooth surface. I'll give it a try at some point.

Default WOODEN SPHERICAL HORNS FOR SALE

Hello,

I disappointed myself with LeCleac'h horns.

They are 1 pair for medium and 1 pair for treble.

Diameter in the mouth of entrance of the throat: 25 mm

Its dimensions of the exit mouth and length are not adjusted to my system.

I would be interested if the shipping were not so expensive. What do the midrange horns weigh?

Tom
