Hiding tweeter array joints

[DaveK]

I'm making my first tweeter array and having trouble getting the glue joints between the units to disappear. Even after sanding I can still where the joint is. Does anybody know a way to make them look just like the surrounding plastic, or is that simply not possible?

Because I could not get ABS glue here, I used a Holdfast product ( sorry don't have the container here to identify it as my gear is stored at present ) which was black and very ruberry.

It required you to prepare the joints by applying a very smelly/fumey pertrochemical substance, leave for 15 mins and then apply the rubbery glue from the tube.

The bond when cured was superb and being black and rubbery, when you trimmed the dags with a knife you could hardly see the joints.

Here it is the black version of ----> http://www.holdfast.co.nz/resources/pdf ... asheet.pdf

Giving away my secrets here. Automotive glazing putty. Used to fill pinholes in bondo. Thin, sets incredibly fast. 200-400 grit sandpaper, flat black paint or duratex after.

Or you could do it the way I do: Not worry about it. Get the joints flush when you glue them, they'll dissappear 10' from the cab.

The 200 was done in that manner, the 250 was trimmed, sanded, painted. Not a lot of difference.

What me worry?

For me I don't. On customers cabs I try to make them seamless. If I ever get the time to sort grill suppliers out it will become moot.

If you ever sort out grill suppliers and sell pre-made grills on your site you are going to be a very popular guy!

Just an OT observation ... seeing the DR200 and the DR250 side-by-side really gives some perspective. In text, a couple inches of difference in dimensions doesn't seem like much.
