8mm dowels in 1/2" material?11/4
Thank you in advance.
We have a Ayen DB21 - drill and dowel insertion machine -- it was designed (eh hem) for both 6mm and 8mm dowels.. however, the machine doesn't work with 6mm dowels ...
Q. Have you, do you... use 8mm dowels in 1/2" material?
Our use will be to make drawer boxes - most of our doweled boxes are 1/2" material - I spoke with a dowel mfg -- that stated he had quite a few drawer makers that used 8mm dowels in 1/2" material.
Before I switch out all the inserters etc -- I'd like to hear from someone who does use 8mm dowels on 1/2" material (Baltic Birch, Pro-Core plywoods etc)
A dowel should have at least half its diameter from the edge of the hole to the edge of the board, so 5/8" with 8MM or 5MM with 1/2" but 5MM bits tend to drift a little for edge bore.
1/2" = 12.5mm
12.5 - 8 = 4.5
Seems to me the easiest solution would be to use 16mm material for drawers?..
Is it possible that the vendor said this because the others are using 8mm dowels for cabinets and use them for drawers for convenience?
There is engineering out there for the 2 x dowel diameter and 1/2 dowel diameter at the edge. The first we heard this was from Europe.
It has since been tested and proved in the US.
If you are using raw PB you would need more than 2x depending on the load.
We have been using 8mm dowels for 1/2" drawer boxes for close to 30 years. Mostly on MCP but have also done on plywood.
