mosaic strips---Finished Riser

Someone needs to do a  How To on mosaic strips for risers.

I Nominate someone else

I'm completely out of mosaic strips, and need to lay up a couple more blocks. The last two i did lasted me 10 years. LOL   I need to get some more Urac 185 to do it...  Uses too much epoxy laying those blocks up.

Actually Nelson Paint Co replaced their Urac 185 with Uni Bond 800.... Same stuff though.... You can lay it up without heat and it has great properties for wood to wood applications, and doesnt kick off real quick. I've used it on dark wood riser footings, as well as furniture before too.

Here is the stuff...   Kirk

I think that's the stuff that Roy uses on his tri lams.

Hey, where is Roy?

We used the stuff a lot building boats and spiral stair case rails using teak. The old Urac 185 was a dark brown glue, and i believe it's still the same, but do not know for sure. You will see the dark glue lines using it with maple or light colored woods, but it works well in wood bow limbs. Just don't try to glue glass to wood with it, or other composites.

I've also used in in parquet flooring and furniture like this one.....

Doing a mosaic strip is nothing more than laminating a bunch of boards together in butcher block style. I use smooth on and have no issues with it.. I don't car to do it much as it is time consuming when I have a bunch of bows waiting to be built.

When it is done though, it does look good and is worth it to me. One block of mosaic material will last me a year or two, but then I usually only use it in my 3 piece recurve bows which account for 20% of my builds at most.

Hey Max, reply #26, page 2, in the Build Along thread at the top has a link to the post that you did last year on making mosaic strips.

Yeah it's all pieced together but I was hoping someone would do one in real time.

I'll put something together in the not so distant future next time I lay up a block.
Big Jim is right....it's pretty simple.  It's just milling a bunch of strips and laying up a butcher block. Then ripping it cross grain into laminations to get your mosaics.

The one thing I can say is sanding those mosaic strips down to .030 thickness can be rather explosive at times....

[Mad Max]

The most important thing to me is NOT grinding end grain when grinding them to .030 or .050

So you are laying up your blocks with cross cut strips so you end up with flat grain mosaics? That's an interesting thought.... Never tried that one before.

I did cut a block  up at 45 degrees one time to get a unique design. But it  sure wasted a lot of material doing it.    Kirk

I did some with HR Maple and thickness sanding was a pain in the b hind

If they have to make a hard bend in your design make sure one of the long pieces end up in the deepest part of the bend and not on a joint.
