So I recently purchased some wood to start my build. It's rough cut 1x6x16ft



When it comes to cutting strips from the raw wood, is a table saw cut good enough?



The use of a planner and joiner, is it just acquiring the proper thickness with the plainer  sufficient or is the joiner necessary as well?



For those of you who built from rough cut, what was the process you used to cut and finish a component before assembly?



Thanks for sharing your thoughts!

Table saw fine if accurate. Measure twice cut once. NEW BLADE take your time. Worked for me. You're going to need lots more wood

Rich,

I cut all my own Sitka spruce from rough 1x6 and 2x6 boards.  I used my jointer to get one side smooth, then cut everything with my table saw. I made everything 1/8" oversized, then ran them through my planer to get exact dimensions I needed.  It took a little time but I enjoyed it.

Brian,

Where did you buy the rough cut Sitka?

I used rough lumber and sawed it with a table saw.Â  Everything worked well.Â  I don't even know what a joiner is.Â  Chuck

Band-saw = less waste. Then use a thickness sander to size material ... or planer.



I have one of these: Grizzly 12" Drum Sander P/N: G0459, excellent machine. Used it on my L-4 build too.

Ben,

MacBeath hardwoods in Salt lake city carries rough cut Sitka Spruce.  I know they have a few locations.

I did the same, I started with an 8x8x16 foot long lump of timber, and the whole machine is made with a small bench saw, cheap bench planer and belt sander.

I'm in the bandsaw camp.  Scribe a line, cut and plane.  Joint remaining surface, lather rinse repeat.



I freehand accurately to a line, no jigs and such, not necessary.

I wish I had a bandsaw that is worth a crap!. I had an old cheap saw that

you have to hold the wood at a 20 degree angle to cut down a line. I took it

to the dump and pushed it off the back of the truck. I finally gave up and

bought a RIGID brand for about $500. Now I have to hold the wood at about a

30 degree angle to follow a line. Totally worthless! I am considering buying

Carter Guides, but I might just be wasting my time and money installing

these on a Rigid saw. Any ideas or suggestions?

I use a wood slicer blade from highland woodworking



http://www.highlandwoodworking.com/woodslicer12resawbandsawblades705to137.aspx



and found some tutorials on youtube for setting up for drift angle.



I guess the resaw blade is actually for resawing wide boards into very thin stock or making veneers, but I like the fact it is only .022 wide, so less waste...

Barry,

I think your problem is the blade and a tune up. I have had good success with either Carter or Timber wolf blades. Next check the tires on the big wheels. Then check tension on the blade. Make sure the blade is tracking correctly. Should be good after that. After all the saw is just a mechanism to spin the blade.

Good luck.

Jack

Jack; if you could make a YouTube video on how to make a bandsaw work the way they're supposed to, it would go viral.  I've fiddled and fussed with the guides and wheels and knobs and adjustments on my (admittedly, inexpensive) bandsaw and I'm like Barry... nothing I do seems to make it want to cut straight and vertical unless I feed the stock into the blade so slowly that I might as well just use hand tools to do it.  Even a jigsaw can cut vertical cuts, but they are hell on thin stock and once the jigsaw starts the stock chattering, I just force the blade through it with plenty of extra outside my cut line to get done and hope I can sand out the imperfections ;o)  Can you understand why I don't work at NASA building space hardware, but build experimental low and slow aircraft instead?  ;o)

I had a band saw, then sold it and got a Ryobi BT3000 table saw. Problems gone.Cut all my 1/4 x 1/2 rib stock, longerons and ply with it...everything, no extra sanding or planing.

I found it more versatile than the band saw.

I have a table saw, which is great for rips and straight cuts. The bandsaw would be for curved cuts.

Barry,



I gotta just fly down and spend an afternoon with y'all.  Guides are the least important part, any of them work fine.  Blade selection and tension are the main players.



I resaw regularly with a 3/16 skip tooth blade on 14" saws up to six inches.  Wide blades only work well on specialty or very heavy duty saws.  The wood slicer works so well because of the thinness of the blade.



Tension is measured in lbs/in sq.  the smaller the cross section of the blade, the smaller the denominator and therefore the higher the tension.



When is your next meeting?
