I am helping an older lady rebuild (assemble?) a light table. It is a nice finished oak frame, originally held together with cross dowels and long screws. Think of the drafting table you used in high school (if you are as old as I am-).

Ref. this Rockler product-

http://www.rockler.com/product.cfm?page=367&site=ROCKLER

But- the holes on her unit require about a one inch dia. dowel. Or should I say- they are about an inch dia. The cross holes are about 3/8 inch dia.

Do you think a smaller dowel could still have enough holding power, sitting over to the edge of the hole? Or should I keep looking for a larger cross dowel? Not sure where else I can look- I have just about exhausted the ‘net.

thoughts? Should I march ahead with the smaller dowels? I could maybe shim out the hole with fender washers.

thx-

Maybe use all thread and double nut it, if I understand your situation correctly.

Bondo- right idea. Wrong size. That is just a little too large. If I were starting from scratch, I might use something like that.

these guys are 3/8 dia.-

but they will sit in a hole with 15/16 dia.

Now that I think on it- I might just buy a package of the little ones and try them. Only out 5 bucks if they don’t work, and hey, it is always fun to go to Rockler, any excuse works.

I don’t know the cost or shipping, but it appears that these may work for you. Page H-5_
Another option might be, to just use a square nut. My old work bench top is put together this way.
wherever strong
right angle joints are required. Fastener
applies even, controlled pressure,
creating a strong joint that can be
quickly assembled or disassembled.
Installation requires drilling one hole
for bolt and one hole for cross dowel.
Dowel is electro-plated steel. 1” Ø x 1-
1/4” L with 3/8” – 16 cross thread.
Cross dowel only 1” O.D. x 7/16” I.D. http://www.organsupply.com/catalog_ordering/view_our_catalog/pdf/Section%207%20-%20Misc.%20Tracker%20Parts.pdf

Hi Dan. Another solution would be a hardwood cross dowel sized to fit the hole and threaded to accept the bolt. I have used wooden cross dowels in my homemade outdoor furniture with wood screws and they have held up perfectly over many years. I do use 8mm unglued dowels on either side of the screw to keep the joint aligned and add strength. The wood screw can be countersunk and plugged for looks.

What you can do is take a piece of dowel that fits the hole; drill a 10mm (13/32”) hole through the end of the dowel for the xdowel; crossdrill a 5/16” hole through the dowel for a 1/4” machine screw

The square nut looks like the best bet. And the cheapest.

Thanks all who replied.
