Secrets of placing dustcaps properly....I seek knowledge

I have been doing some refoaming lately, but I rarely pull dustcaps when I do this. I have a set of Infinity RS1.5 poly Watkins woofers I am working on now, and they had dissimilar dustcaps and what looked to be a previous refoam.

I have the replacement dustcaps, which are cloth screen type like the originals. I'm wondering what methods others use to place them without dropping them and getting glue all over the cones.

Sorry if this has been discussed ad nauseam. I searched and didn't find anything.

Edited to clarify the issue. Sorry.

So, you got fabric surround woofers....presumably for bass reflex/ported enclosures? If for sealed enclosures, they are not suitable.

If they are bass reflex cabinets, mesh surrounds might not be as critical. But then again....?

I had some midranges rebuilt once and they came back with mesh surrounds. The cabinets were bass reflex but had a duct & chamber system. I figured that air escaping around the midrange cone was not a good thing....that the system depended on air pressure being directed in a certain fashion.

I wound up doping the mesh on the assumption of that being so.
 
Id save the old dust caps and re-use them.

Maybe some tape stuck to the dust cap and lower it carefully onto the cone ?


@62vauxhall i think he's just using foam surrounds. But I think the semi-transparent mesh dust caps might not be the best choice for a sealed enclosure either. Air will escape through the spider and voice coil gap then out through the dust cap
 
I think the infinity woofers I am refoaming used the mesh caps to vent the coil/pole. The one original cap i had was the same material. I edited the original post to clarify.

This is my suggestion as well, use a piece of tape made into a loop and lower it carefully into position. Test fit first to make sure it's centered. You may want to make a few small pencil markers for when gluing.
 
Most dust caps have a rim around the edges. Glue the cone, and carefully drop the cap in place using a roach cli ... er ... hemostat or tweezers. You should have plenty of time to adjust the position. Once you're happy with it, press it in place in a few spots using a small blunt stick or whatever, then a final go around to set it firmly.
