[quote author=Adrian D. link=1129899653/0#11 date=1130155746]My only concern is about the angle cuts, because i have a jig-saw (go ahead laugh, i built a db-10 and a db-12 spot-on with it) and i'm afraid i won't be able to set the angle very precisely... measuring and finding angles isn't a concern at all, because i love geometry

what should i use to fill the gaps if i don't get my angles right ? is it that thing used at cars to fill the small dents in the bodywork (sorry, i don't know the name), but for wood use ?
i just hope i won't like it more than my dbs.... ???

Not laughing ........ wrinkling my brow. A jigsaw will fight you when you try to cut MDF to precise angles.
>:( <<< That's you after a few tries.
All is not lost, because you can always cut it long and sand it perfect. That will be infuriating, too.
If you lay out the plans and consider your cuts carefully, there are only 3 precise angled boards to cut on each side if you use butt joints. In other words, where two boards meet only one must be cut perfectly to connect them and the adjoining board can be cut slightly long and later be sanded flush after the glue dries. A belt sander is a great help for that, but a hand rasp will work.
It won't be easy, but your great grandfather built his world without fancy power tools. You will need to call on your "old world" craftmanship and determination to complete the build. I'm not trying to patronize you, but rather encourage you not to give up, even considering it will take 4 times as long for you to do it right with simple tools.
I would do not depend heavily on wood fillers to correct for bad cuts ..... get the cuts as close as possible before you glue and your joints will be much stronger.
You mentioned that you aren't starting the project right away, so you have time to plan it all out. One thing you might consider is a part time job at the mill where you had work done before. You might be able to earn some table saw privelidges there. Or maybe a classmate has a father or uncle with carpentry tools and you could get him interested in the project and build one for each of you.
My point is that if you want a WO, you can build one in spite of the challenges you face.

Sorry, that part is not negotiable. You will like the WO much more than your DBs.
The 3rd one I helped build was done mainly by a youngster, your age and he was not a "sawsman" and his worked fine with all of his mistakes filled with silicone.
