Hello lumberjocks, This project was constructed with hard maple. Many projects i have seen in the past are made with salvaged wood. Here is another example. I used scrap 4×4 wood that was used as dunnage(spacers) between bundles of steel. This wood is not flat cut and i dont think you would want to use it for furniture or other fine woodworking, but for a project like this you just couldnt beat it, considering it was all free. The black 1/2” plate underneath the lathe is made for extra wieght and hopefully will take out any vibration. I set up a grinder to show the idea for the extended table, that is not the grinder i will be using to sharpen my tools, I am currently still saving up for a steel city variable speed grinder.(i need a raise in my allowance =) ). These 4×4 were hard maple, I also get red oak once in awhile. Its really nice that they save this for me, they also like the fact that this wood does not go to a landfill. I think any wood saved from a landfilll and is put into a project is great. Thumbs up to the guys who are able to do this!!!
