Veneering 45 degree chamfer *PIC*

Does anyone know how you can do this. Like the way it's done with drake? I think unbacked veneer will crack. Would paper backed veneer less likely to crack? Also, how would you trim the bottom? That tiny triangular bevel on the bottom looks like next to impossible to do.

The chamfer on the bottom is the same as the chamfer on the edge facing forward. You don't bend the veneer over the chamfers; you veneer the corner chamfers first, trim them flush with the edges, then veneer the edges, trim them flush with the sides, then veneer the sides, top and (if you want to) the bottom.

Having said that, while I understand the theory, I confess I've never actually done this. Perhaps one of our expert woodworkers will chime in.

HTH,
Bill

A lot of those type are done with a solid hardwood corner piece. One way is build a box of MDF, then another box on top of that with the same size panels in a nice ply. Now you have that thickness you need, but the faces don't overlap at all - then use stock cut at a 45 or some use quarter round. Some build the box, use a rabbeting bit on all the corners, then fill with chamfered hardwood stock.

i have done something close w/ iron on veneer. the only thing i did different was chamfer the edges on a router table. this eliminates the little triangle piece on the four cornere. i do not have any photos, but the solid model should give you an idea of what i did.

the order probably did not matter, but i ironed on the sides first then chamfered all edges. i started ironing on the chamfers at the bottom of the back, then trimmed flush with an exacto knife. i did not have a flush trim bit at the time.

i proceed to work my way up and forward. that way, the trimmed edges would be out of sight. it looked really good...until i ruined it in the finishing stages. live and learn.

the model is a little misleading. with the build pictured, i put hardwood edges around an mdf box and left them square. i just added the chamfers to the model so you could see what i meant by removing the little triangle. this chamfer/veneer technique was used on a sub that i do not have pictures of. i will say that chamfering the mdf and adding the veneering was MUCH easier then adding hardward edges. if you woodworking is not that great, stick with chamfer/veneer technique.

Hi Bill,

That's exactly how I did it, and I just sort of made up the process as I went. Looks like great minds think alike!

See ya,

Darren
