The first cut with my homemade bandsaw.


The parts for the complete machine costs me 150$.

It runs very well, but sometimes i have some problems with the linearity of the cut, the surface gets a little "wave".

May be, that the blade tension is too low.

Greetings from germany

Very nice job! Even my wife enjoyed seeing the planks comin off those logs. Made me remember workin at the mill back home when I was a teenager.

First off, welcome to the fray, Hugy. You won't find a nicer or more talented group of guys anywhere as you will here. Time and again I've just been flabberghasted at the quality and ingenuity of thr various projects on display here.

I wasn't able to view the video as I don't run Flash at all on my computer. But besides blade tension, the other thing that contributes to cut uniformity on a band type saw is the blade guides. Even on short blade exposues on metal cutting bandsaws you will find some sort of guide or bearing surface that the blade runs against.
As to fixing any wavy cuts, the best tool would unquestioningly be a good surface planer. A few years back I constructed a chainsaw jig mill using two long lengths of deep "Unistrut" channel with a little dolly carrier that ran on the rails and would guide a 24" chainsaw blade along in a straight line. Got amazingly good cuts just cutting douglas fir. But just how good the wood looked had to wait for that first pass through my Dewalt two speed surface planer. As a fellow wood butcher I will atest to the great joy of actually constructing something out of wood that you have felled and processed yourself.

A few sites you might find of interest are:
Forestry forum
Woodweb site

Best of luck and again welcome to the fray.

looks good guessing your using vegie oil so it doesnt stain wood?
watch too much tention on the blade it will bind or snap/ very tricky to get it in proper tention

In my experience A good blade contributes more to the straightness of the cut than anything else. You get the wave because one side of the blade is "sharper" than the other; you can try to balance that unevenness by tightening the blade or adjusting the guides but the blade is still going to try to drift one way or the other.

A simple test to determine if it is either a guide or blade problem is to watch the blade behavior while cutting. If the blade "dives" (twists to outside relative to wheels) as you apply pressure to cut, but returns to center of cut as you let up, it's likely a guide problem. At least that's what I learned from the four years working in my fathers cabinet shop back in the 70's.
