Thread: 4mm acrylic sheets? or 1/8 LED sign base

  1. #1

    4mm acrylic sheets? or 1/8 LED sign base

    The sign bases I have purchased (Amazon) are for 4mm acrylic, the 1/8" is to loose and my 3/16 signs do not fit in the slot.
    I have searched and found no US distributor of 4mm cast acrylic. and I can not find the bases for 1/8 sheets.

    Any ideas?

    Tap Plastics has it in 1/8” or 4.5mm. Odd that Amazon is selling bases that are not for standard thicknesses.

    Those round "hockey puck" bases that come with a remote for ~5.00 are from China, they work great.
    But the standard thicknesses in the rest of the word (outside the US) is metric.
    Those bases are made for a 4mm sheet, a 1/8" flops around, the 3/16 will not fit.

    Wrap a piece of electrical tap around the base of your acrylic. It will snug it up in the base and give you better light diffusion.

    You know it will work, I know it will work. But giving someone a gift with some "duct tape" wrapped around it to make it fit,, just doesn't look good

    Found some 4mm on ebay,, but literally twice the price of 1/8"
    It is actually kinda funny, the Chinese are flooding the US market with nice, cheap LED acrylic sign bases,, made for metric sized acrylic that is not available in the US,, opps

    the 4mm on ebay will be sloppy also as its not true 4mm
    pretty easy to make your own LED wood base if it for a gift you'll be much happier with a custom made base.

    What are these sign bases, wood, acrylic, anything you can buy yourself without a slot?

    A table saw with an 1/8" blade set to 10° and 1/4" deep will cut a perfect slot for an 1/8" thick sign...

    I have a wood/metal shop, but it's not worth my time.
    The round black plastic "pucks" do the job. She can whip out a sign/picture and stuff it in a $5 puck and it is a fully functioning lighted example.

    I have found the 4 packs with remotes on sale for $24

    Ordered some of the 4mm material, we shall see.

    Maybe you could cut a slotted rectangle out of acrylic as a filler. The rectangle would be 1/4" wide (slot width) and as long as the base's slot, and a 1/8" slot in the middle of the rectangle to snugly hold your acrylic panel. Cutting one rectangle from a thicker piece or stack multiple rectangles cut from 1/8" to get the depth you want (can join with a bit of weldon or cya) to keep your acrylic panel from wobbling front and back. A few minutes of waiting on the laser...

    The bases I've seen over the years had a thick piece of felt like material around them, like weather stripping. It would allow you to use a variety of material thicknesses.
