Hi Guys,
Anyone gluing aluminum to acrylic and having the bond hold up?
I've tried a few different times and got to the point to where I can drill out the parts sucessfully, but then it eventually break shortly after drilling or when I try to tap it.
Looking at the broken sections, it appears that the glue is always on the arylic and breaks away from the aluminum.
I'm using the same procedures I use for acrylic to acrylic, but there must be something I have to do differently to get the bond to hold. Any suggestions would be helpful.
Gluing... I've been using good quality CA (gap filling) glue. Sanding the both parts with heavy sandpaper to get a good bond. Giving it plenty of time for curing (a few days). Is there a different glue I should be using?
Drilling... Like I said, I got that part down, but... using freshly sharpened bits. Drilling small hole to start and work up to final size. Using very slow speed and taking VERY light passes. Bit is staying cool. Applying lubircant before each pass.
Thickness... Not that it should matter, but I'm using fairly thin peices of aluminum (.045" & .021.
I've read where aluminum won't hold a joint over time because of the way it oxidizes, but I've seen plenty of pens with aluminum segments in them (unless they were using a different metal)?
Is there a way to do it, or must I figure out a way to create a mechanical joint instead of gluing if I want to do this?
Thanks...JEB
