Nope.

Bevel half way down the length of the fence post and then switch to the opposite angle (not side).

You shouldn't be to quick to point to your "elevator" as an engineering success. It violates building/safety and fire codes in every county within the United States. Anyone with access to an auto wrecking yard could do the same.

Instead of a hobby of making things cheap, maybe you could change to making things of quality. Not everything you make is an "Invention".
Yes, it certainly violate a lot of regulations.

Don't you LOVE regulations?

It still works fine after 8 years of continuous use.

Most of the 49,500 people who viewed it seem to like it and many have asked for plans.

Are you trying to use this challenge show that there is some use to your upside-down table saw thingy?

That should really have just been a statement.

Plus possibly an opinion on it.

I'm not in the discussion myself, whatever gets your job done as far as I'm concerned. Didn't see anything to argue over in the first place.

Here's the story.

I had a table saw and I REALLY needed to do what I asked in the challenge.

My table saw frustrated me to no end.

As a result, I invented the Upside Down Radial Saw.

(You can see the old table from the 'table saw' beneath the slide table.

With the new setup I can angle the blade left or right and do cuts that are impossible on an ordinary table saw.

Call it a 'thingy', but it gets the job done, and it is extremely safe and fun to use.

I also invented an upside down sliding jig saw; but that is another story.

Guys, loosen up a little, and give this old geezer some slack.

Oh i love these puzzles. I think i have the answer. Wow when you say table saw i immediately imagine putting the stock on the table so that one of the 12" x 3" faces is on the table and i think that is the problem. I believe if you were to put one of the 12" x 1/2" faces on the table, tilt the blade to 45* and cut half way down like that then back the stock out rotate it 180* without lifting it from the table and make the second cut. You may have to clean it up by setting the blade back to straight up and setting its height and making a cut down the middle to allow the two cut off pieces to fall away.

Did I get it? I think that would work.

What reason is there that I'm not allowed to turn it over?

If I could see a good reason why turning it over was a problem it would be a different matter, but this isn't precision machining where if I take the work piece out of the jig I'll never get it lined up again.
After all, it's wood - it changes shape and size with humidity, there's no sense in trying to be precise to tiny fractions.

Stu, you are welcome to your projects and ideas, but it does get a little wearing that you get up on your high horse to defend them whenever someone says "Actually mate, there's another way of doing this".

If your invention suffices for your purposes, don't feel you have to defend it! However, at the same time, don't tell everyone else that their way can't possibly work - there is more than one way to skin a cat.
Yes, perhaps their tool can't do all the things your tool can - perhaps your tool can do something much easier - but I'd also bet that your tool also can't do everything their tool can and would struggle where their tool would breeze through.

The reason people get snarky when you come along with your new ideas is that you treat them like they're the best thing since sliced bread and reject criticisms of them. If you were prepared to be more objective over the potential of your ideas, then people would be less likely to concern themselves with its shortcomings.

If your response to "Well, it wouldn't do X very well" was a modest "No it wouldn't, but I don't need it to" rather than a more confrontational accusation about the (often largely irrelevant) shortcomings of every alternative presented, we wouldn't end up descending into these fractious and ultimately fruitless discussions.

I know you'd like to receive affirmation of the potential of your ideas, but internet forums tend to be more a source of criticisms (although usually constructive in nature) than of praise. Indeed, on one forum I go on, the general rule of thumb is that a lack of response is more indicative of people having looked at it and not seeing anything to criticise than of it being poorly received.

If you're not looking for feedback and potential shortcomings, and are only looking for polite praise, then Spudfiles is probably not the best place to come for that.

Take a 3" x12" x 1/2" piece of stock.

Bevel a 45* angle half way down edge of the stock at this angle \

and continue the bevel the rest of the way at this angle /.

You may not turn the stock upside down or lift it from its flat, on the table position.

Can you do it on your table saw?

Stu...REALLY? :roll:

If you've ever used a table saw, then you're well aware that the blade only tilts in one direction. Table saws ARE available in right or left tilt...but not both.

Putting forth a "challenge" and then adding a ridiculous caveat which renders the challenge impossible does little in my mind to further your cause.

Were you hoping no one would notice you offered a "rigged" challenge? :roll:


Edit: Some finer points about your challenge continue to interest me.

Can you perform your own challenge on your saw? :)

You can't lift the blade to change the angle as it's already on an angle to the wood...it'll bind on the wood if you try.

You can't change the angle without lifting the blade either...the wood is in the way.

Tough one eh? :lol:

No. Read the challenge again.

" Table saws ARE available in right or left tilt...but not both."

A great solution! Buy a pair of table saws.

If all table saws had the ability to tilt in both directions, it would do the job. Retract the blade, reverse its angle, and raise it.


That is the whole point of my story.

I was cutting on my table saw and I realized that it was impossible for me to continue my project. I finished the job with a jig saw.

My upside down jig saw table was based on my extremely powerful Milwaukee demolition saw. It could cut wood and steel with opposite angle bevels.

The up and down cutting motion of a jig saw is much safer than a rotating blade table saw.

Band saws and a jig saws make perfect blind cuts.

(Blind cuts can be made on a table saw with some effort.)

A demo saw with the right blade could cut through almost anything.

Instant blade change is really convenient.

I offered my design to some major companies without success.

At the same time I invented a double ended, double edged demolition saw blade that offered 4 cutting edges.

Can you see it?

Stu, that still doesn't explain why we're not allowed to turn the work piece over! It also doesn't explain why we're not allowed to do it with a jigsaw - which you have just admitted that you have managed!

Unless you give a valid example of why we must continue the bevel without turning it over, and why it must be done on a table saw rather than with the far more common tool of a jigsaw, then your whole argument is rendered moot by the fact it doesn't actually need to be done.

That reminds me - have you got a machine that can coat the inside of a saxophone with an even thickness of toothpaste? And can it do it from the outside of the saxophone?
Why from the outside? Just because.

It doesn't matter, because the circumstances in which you might need to do such a thing under what are rather daft self imposed limitations are inconceivably slim.

You are usually pretty smart.

Think about what you said.

If it were as simple as turning the piece upside down, I would have done it.

Turning it over would put the bevel on the wrong edge.

A pair of table saws (left and right) would have done it.

This was a real world problem, not a silly toothpaste issue.
