I have an odd request from a friend.  He wants me to saw him up a triangular cant.  I have  Woodmizer lt10 manual bandsaw.  Not my idea but a strange request indeed.  It is apprently for a totem pole.  Can it be done?  Perhaps by shimming or something?

How big? I would use a jack too. Others have probably done it. I will bookmark this thread so I will know how too.

I have unintentionally made them...... ;D   :D

Seriously, you will need to "wedge up" one side to get your angle.  Possibly even make a jig to hold the cant securely for the cuts.

Some pictures of your progress will be interesting.

a jig, now there is an idea.  Thanks, Majicman. If I were to first  cut a square cant and then build a sawable jig to hold the square cant at 45*, i would only have to run the darn thing through once.  I'll bet I could hit every nail in that jig twce even if I sawed 45* one time.

  Made them a few times.   Open the log and get the width that you are looking for, keep the slab closeby, turn and saw second face so that you now have a 90° angle face.

you now have two faces of the triangle, what I do for the third is put the slabs back on with screws, keep the screws near the point of the triangle...(away from the blade ...). turn the log and with a square from the point of the two faces, square the log up and clamp in place and saw the last face so that all sides are of equal width. I have tapper compensators on my mill, you may need to use a jack to lift and get the faces just right, a little time consumming but once you do one it gets easier .    ;)

Thanks Isaw, That sounds like it would worksaw.

cfarm, I don't know how big he wants this thing just yet.

Magicman is correct "if" what your customer wants is an equilateral triangle (same angle on all corners), but ..... maybe you should ask what the application is. It's possible that what he wants is a right-angle triangle (two 45's and a 90) to be used in a corner ... ??

I'm trying to recall some of those figures as my mind floats back to the shapes and sizes of figures in Geometry class.  OK, I'll try for another reprieve.  In those days I think at 17 years of age my mind may have drifted to shapes other than were provided for in the text book. That's my story and I am sticking to it. 

I am thnking that if a cant is cut square and the cant was sawed corner to corner, the angle for holding the log would still be 45* if it was a right triangle when complated.  right

If you cut a square cant in half diagonally, you will have 2 pieces that have the shape of right triangles. A right triangle is any triangle with one 90deg angle. Any triangle when adding up the total of all the angles will always =180. An equilateral triangle has 3 = angles and thusly 3 equal length sides.  Pythagoreans theorem for right triangles is the lengths of the short sides squared and added together equals the length of the hypotenuse (long side) squared.  A squared + B squared = C squared.

Rimshot,
A good idea to find out what the customer has in mind for a "triangle".  :)

Rim,

I think at that point in life, I was studying curves, not angles...

I think the formula would be (a square+b square=square root c) Old and fuzzy, but I think it's right.     Andy

Better go back and check that fuzzy logic out.   ;D

If you want to solve for C, then the square root of the quantity (a squared + b squared) will give you the value for C.  ;)

Negative. He had it right... "For any right triangle, the sum of the squares of the sides is equal to the square of the hypoteneuse." ... or something like that.

Why couldn't you build a jig that sits against the dogs and on the table that holds your cant at the correct angle? You cut the top of your log, put the jig in place, roll the log so  that the freshly cut side is against the jig, cut second side of triangle, roll again so that side is on the jig, and then cut the third side. Clamping the last cut would be the most difficult part, I think...

Redbeard, my head is hurting looking at that jig of yours!  Nice workmanship, Ibet it took a bit of thinking to make that jig-5 separate pieces? glued and screwed together?  Looks very handy 8)

Back to the diversion, wasnt it the wolf man who said 'baby you got the curves but I got the angles. i still remember [some of] the 60's and 70's. thanks for the reminder!

It was all a giant conspiracy to keep us out of the triangular shaped log cant business. (big grin).  Hips or  hypotenuses, either or could get a young man in trouble back in those days.
