I need to put up some beautiful American Black Walnut shelves ( I got
the name of S.L hardwoods through this NG and they did a great job).
Now I need to put em up, with no supports showing....The shelves are
400 mm wide, 200 mm deep and 40mm thick. I am worried about the
accuracy of my drilling and came across this post from a couple of
years ago.... (for the whole post go tohttp://tinyurl.com/ry4n )

Like those Ikea Lack shelves. Any ideas anyone?

Yes - you need:

1. A big masonry bit
2. Several lengths of studding (AKA threaded steel rod)
3. some polyester resin
4. A drill stand if you don't think you can drill into the edge of the
mantlepiece accurately hands-free with your black-and-decker :-)


See an example of how to fix the studding into the wall in current
Screwfix catalog on page 17. Use the thickest stud possible as
the thinner the stud the more flexible it will be and your mantlepiece
will move up and down.

Haven't done this yet - but doing so very soon with some shelving so
all other advice much appreciated :-)

I don't have a screwfix catalog and speaking to the tech support there was not much help.

My question is, willl this work and where can I buy the resin, I just had a look in a B&q Warehouse and I couldn't work out what the product (polyester resin) was. does anyone have a brand name? Or any more advice?

The trade call these 'chemical anchors' - try a google search. I guess
your problem will be finding a retail source for a small amount. There
are a number of polyester resins readily available eg car body filler
and the resins used for fibreglass work sold by boating specialists but
you will need something of the right viscosity and an injection method
to get the resin to the bottom of the hole cleanly and quickly. You will
also need a way of hold your shelf plumb as the resin cures - there will
be no shifting it once it has set. These resins will have a pot life
measured in low 10s of minutes, accuracy and speed will be vital as will
practice on some scrap before doing the real job.

This is a potentially high risk- high payback method for DIY

Good luck
