In Mexico fine furniture is not too popular. Six months of hot and dry, then six months of rainy season (rains mostly at night). I know of people that had their furniture shipped down from the US and where surprised at the movement of the wood in a short time. The people around here are simple hard working people and useful stuff is what they prefer. In need of making many tenons I came up with this jig and it seems to work great. Pretty primative on the building, didnt know if it would work so didnt build too elegant, have to build another one. The clamps are a little overbuild, couldn't find any T-nuts, so I embedded some wing nuts in the handle part. This design I'm sure is not original. Also trying to teach a couple of lads a few basic skills on wood, they work in the fields for about $12 a day, a skill would come in handy for them later. The pics pretty much tell it all, check it out and give me some suggestions when I build the next one.
