 Don4644 posts in 3571 days 10-19-2009 02:14 AM Topic tags/keywords: angles miters sled lap joint I’m building a wine cellar with a wall of four built in units, the top one being a 7 foot wide x 10 inch high (external dimensions) horizontal cabinet. I want to insert diagonal “shelves” using 1×4 half inch oak boards to create a visually pleasing row of individual bottles above the main units. I want to make the diagonal Xs come out evenly, so I have subdivided the cabinet into three sections, and have room for 3 Xs on each side and 4 in the middle. Each X on the side is 8.5 inches high by 7.5 inches wide on the sides, and 8.5 high by 7 inches wide for the middle. I want to miter cut the ends and use a half lap joint at the center of the Xs. How does one figure out the angles to set the miter saw to cut the ends? For the half lap joints I am using my table saw. I know how to do this for 90 degree Xs: I use my cross cut sled on the table saw and cut out slots half way through the 1×4 oak. What angle should I cut these lap joints?What is the best way to do this for an angle cut that is not a 90 degree cut? -- --Don, Folly Beach, SC

In order to accommodate a wine bottle (about 3 inches in diameter) I need to flatten the X within the 7.5×8.5 rectangle, if you follow. One miter cut on each end with the long side in the corner. I’m no good with sketchup or I’d draw what I’m thinking. I’m still not clear on how to execute the lap joint cuts. thanks, -- --Don, Folly Beach, SC Moron5032 posts in 3862 days #3 posted 10-19-2009 12:47 PM Why complicate it. The wine wont care, neither will the consumer of said wine. Why not make all lap joints 90 degrees and all ends at 45 degrees -- "Good artists borrow, great artists steal”…..Picasso Moron5032 posts in 3862 days #4 posted 10-19-2009 02:12 PM When I built my wine cellar I “changed it up”. One wall has vertical dividers, with horizontal “slots” using magic wires, another has square boxes put on 45 degree angles biscuited together, and another has section made into slots buch like your doing but for individual bottles. The little spaces that are left at the edges recieved a face frame to hide them. I put in a few shelves with faux stone back grounds. then I drank all the wine and in the end…................I knew I couldnt afford to keep it full but it looks nice !!! -- "Good artists borrow, great artists steal”…..Picasso Don4644 posts in 3571 days #5 posted 10-19-2009 03:04 PM I believe I can use Four 8.5 inch “square” Xs with 90 degree lap joints in the center bay, which has 35 inches inside dimension. The two side bays allow only 22 3/8 inches ID, and that is where I am having the problem. The three bays are defined by two side cabinets below them, so that the stiles will be continuous from top to bottom. But as I’m writing this I’m already rethinking the need for three bays up top. In a perfect world all of this designing would have been worked out exactly on paper (sketchup certainly) and all it would take is executing the design, but it seems like a lot of my design and construction decisions are being made on the ground as the process unfolds. thanks Don -- --Don, Folly Beach, SC Don4644 posts in 3571 days #6 posted 10-19-2009 03:13 PM Roman, I looked at your project gallery hoping to see your wine bins, but, alas, you had several other impressive projects, but not the wine cellar. I will have small diagonals on top for individual bottles, and large diagonals on the side. In the middle I’m using shelves with wine cases made of pine and with decorative vineyard labels on the ends. There is a counter/bar on top of the middle case where I’ll have a few upright bottles. I’ll post pictures when I’m finished. thanksDon -- --Don, Folly Beach, SC Moron5032 posts in 3862 days #7 posted 10-20-2009 04:40 AM sadly 3 out of 4 projects never get photographed but I shall remain steadfast in my belief to keep it KISS keep it simple….............. -- "Good artists borrow, great artists steal”…..Picasso Don4644 posts in 3571 days #8 posted 10-22-2009 05:35 AM Looks good. I can’t link to the post at photo bucket for some reason. It asks me to sign in but then I don’t know how to locate your link. I have diagonals on the sides but decided to go with individual slots across the top. I’ll post pictures rather than try to describe it.Grand opening tomorrow evening. I bought 2 cases today but it barely fills two bins. thanks everyone for your help.Don -- --Don, Folly Beach, SC
