Topic tags/keywords: question milling

I am working on a speaker stand project and the riser needs to match the front of the speaker which has a 100 degree angle on the front.

Any suggestions how I can rip boards at 50* since my TS only angles to 45 degrees?

Thanks in advance!

I would run it through my bandsaw and clean it up on the jointer

How about you set it at 40 and use the other side?

Good idea from Charlie.

You could rip to 45 and do the rest of the angle
on a jointer or with hand planes. On the jointer
you set the fence to 45 and tape a strip of wood
to the workpiece so the angle of presentation
of the work to the cutterhead is a little steeper.

A little geometry lesson though – in order to
make a miter more obtuse than 90 degrees
you actually want more obtuse cuts on the individual
ends. To make an 80 degree corner you subtract
80 from 180 = 100 and divide by 2 = 50.

In order to get a 100 degree (obtuse) corner,
subtract 100 from 180 = 80/2 = 40.

Table saw normally cuts angles subtracted from 90
degrees, so to cut 10 degrees off 90 (100 on
the acute corner and 80 on the obtuse one)
the blade is angled 10 degrees.

Two 90 degree ends butt together to make
a 180 degree flat joint. Remove 1 degree and
the angle becomes an obtuse miter. It is
the acute, pointy miters that present challenges
on the table saw. Old variety saws used
by patternmakers have tilting fences as
well as tilting arbors.

90 minus 50 equals 40 – what he said.

Thanks to everyone for the quick replies. I think I will use Charlie’s solution. I guess it was time to quit for the day if I wasn’t able to figure that out by myself. LOL

Don’t feel bad Art. No one is more “angle dyslexic” than I am!

Hi Art,
I think Charlie has the right idea … but here is a neat way to insert a ° in your text:
push and hold the ALT, inter 0176, and release the ALT … Is this cool or what …
(The em-bear-ass-ing thing is that I learned that from my g-grand daughter) color me humble.

Mike, I knew there was some secret code to do it and I think there is a chart that can be found in Windows listing all kinds of special characters, but I’m lazy, so rather than looking it up, I just type it out on this site. :) Other sites let me use the ”*” character, but that gets me bold font on LJ.

I did rip the pieces this AM and it worked fine. I am just waiting for the glue to dry so I can take the next step.

I can’t get the 0176 thing to work I hold ALT and enter 0176 and release the ALT key and it stays blank.

Jerry, Maybe its a west of the Missippi thing?
Could it be a Windows item and you are on an Apple
?
I really don’t have a clue why your having a problem, I’m not a computer guy, I have to ask the kids, grand kids or the g-great grand kids …

Art,
Yeah, I know what you mean, ... I have one and only one memorized, don’t know where to look up the rest so I spell it out.

OK, this only works on my number key pad on the right side of the keyboard. It does not seem to work using the numbers across the top of the keyboard. °

Hold on a doggoned minute.

If one rips a board on a 40 degree ( iPad doesn’t have an alt key) bevel, the cutoff piece will be at 40 degrees as well. The heel of the cut will be at 50 degrees.

In order to achieve a 50 degree bevel, one would need to set the saw back to 90 and recut at the short point of the bevel created previously at 40 degrees.

Perhaps a jig is in order here. That is a pretty squirrelly cut to make, let alone the potential danger if attempting to utilize the fence as a guide for the long point of the bevel.

Thanks Horizontal Mike

different symbols appear, however, I must use the keypad on the right side of the key board.
