I said it wasn't. You then replied with a sharp remark that if I don't know what a complementary angle is, then I should get off the thread. I looked up the actual definition of "comp-lementary angle", and I was right -- A and B are complementary iff they add up to 90. How is this "twist[ing] anything"? -- Andy Barss : -- : www.e-woodshop.net : Last update: 3/13/04 -- Andy Barss Department of Linguistics, University of Arizona Douglass 208, 626-3284 |

I pivoted the fence near the blade end then glued blocks at points a
little more than 45°. Tee nuts in them also allowed card stck to be used as shims to get right-on 45°.

Tee nuts in them also allowed card stck to be used as shims to get right-on 45°. ================================================== ==== Basically the way I make all my sleds. I have my fence pivot near the blade.... BUT I then rout a 3/8 " wide slot in the top of the base... and rout a 1/8 inch deep 3/4 inch wide slot in the bottom of the base...(to hold a ) Then drill a 1/4 in hole in the far end of the fence ..away from the blade... This allows the fence to be Locked down and be solid anywhere along that 1" in long slot... .. The Block has a fine threaded carriage bolt to allow me to finely adjust the fence. Then I just lock the fine threaded carriage bolt again sat the back side of the fence and tighten the fence down ... Extremely rare for me to have to re-adjust the sleds...But when I do it is only a 2 minute job..... Bob Griffiths |

Look, all I was trying to do was make explicit an implicit assumption of your post. Explicitly: the two angles need to not just sum to 90, they need to be very close to 45 degrees if the joint doesn't look and feel off. You know that; I know that; an inexperienced person doesn't. So I was just trying to add some helpful clarity to your post. -- Andy Barss : : While I will grant you that the "length' of cut becomes an issue the : _wider_ : : the stock, you are apparently assuming that most miter joints cut this : way : : are done in wide stock and the angular error is great enough.

Andrew ... that is EXACTLY what you are saying below. : In that post you said, and this is an exact quote: : : 45 degrees _is_ the complementary angle to 90 degrees. Which is it, Andrew? ... Can you see the corner you have boxed yourself into because you didn't read and understand what was being discussed, then you compounded your error by entirely making up the first statement above? : This is the remark I challenged, and the one you're wrong on. : Nothing wrong with that statement at all ... just think about it a bit : longer. : (Hint: what do you add to a 45 degree angle to get a 90 degree angle/joint?) 45, of course. Now, we're getting somehwere! But when you say 45 is the complementary angle to 90, you're dead wrong. As I said, 45 is complementary to 45, 80 is complementary to 10, and zero is complementary to 90. No argument whatsover, However, also by accepted definition, "The complement of something is what is required in order to complete it". In the statement you keep taking out of context (what went before it, Andrew), 45 degrees is what was required to in order complete the joint _under discusssion_ to 90 degrees. Granted, it may take a bit more intelligence than you've exhibited thus far to grasp the correctness of the statement, but it IS correct, even when taken out of context, as you have done.. Look, I was just correcting you on your misuse of a technical term from geometry. No need to go ballistic. LOL ... My take is that you've proved yourself far too fallible in both reading comprehension, and in attributing statements that were never uttered, to be "correcting" anyone. -- www.e-woodshop.net Last update: 3/15/04 |
