I am building a wine cellar and would like some thoughts on my best option for joining the shelving I will be using. The shelving will consist of 18mm bamboo plywood horizontals held between 25mm bamboo ply verticals.
Main dimensions etc. are as follows:
Depth of verticals/horizontals 30.9 and 30.4 cm respectively
To maximize access to the bins and wine bottles I can store I am building this as just verticals and horizontals – i.e. no front or back support, edging strips etc. So a couple of remarks about steps I will take to reduce racking stresses:
I am not particularly concerned about shelf sagging, given the depth of the shelves and the fact they will all be fixed. Even the longest span should I think be fine, given it will “only” need to support 30 kg across its width of 101 cm. I also think the units will not have any significant racking given the points I mention above.
What I would like opinions on is my best method for joining the verticals and horizontals. This is a big project, with 104 horizontals fitting inbetween a total of 19 verticals. Because of the number of pieces of wood necessary and the fact that bamboo is so hard on tools I have had my wood supplier already cut the verticals and horizontals for me, so these dimensions are fixed and I quite intentionally did not plan an setting the horizontals into dados (given the verticals are 25 mm thick).
This means I am looking for a joinery solution to fix the horizontals between my verticals (the units will range from being only one module of shelves wide to consisting of 5 modules of shelving – i.e. 6 verticals supporting 5 sets of shelves between them). What will count for me is speed, accuracy and ability to set up quickly for repetive work. Aesthetics is a concern but not huge….wine bottles will cover these shelves and the junction between horizontals and vergicals soon enough.
Options I am considering are:
1. Dowelling and gluing.
If I go with dowelling I would likely buy a Dowelmax jig. Similarly, would pick up a Kreg or similar jig if I go with pocket-holes.
I suppose I have a slight preference for dowelling and gluing as one wouldn’t see the pocket-hole drill holes. On the other hand the pocket-hole approach has the advantage of not needing clamping during assembly as the screws will pull the verticals and horizontals together. I did briefly consider cross-dowels (barrel nuts), although this option seems to me to be too time consuming for the setting up and drilling involved (although is a very strong joinery method).
In the end, I find myself leaning to dowelling/gluing and have thought I could perhaps get the best of both worlds going with dowelling with the Dowelmax as it seems to me at the time I drill the holes in the verticals for the dowels I could also drill out a smaller pilot hole for something like 8mm woodscrews using one of the other bushings. I could then have the very first horizontal/vertical joints only making use of dowels and glue but as I add on each new vertical I could put a couple of screws through these pilot holes and countersink them before adding on the next module of horizontals.
