I have a great idea!!!
How about a simple wooden block cut to an exact fit by trial and error that would support the table!!!
Oh, yeah... That is where MCCABINETMAKER started us out... :D :D :D :D

OK, it is still fun reinventing the wheel...
Next week we will rediscover fire.

Yes - exactly! The problem is that this gauge is too long.
I'm thinking that gauge can be cut to a shorter length.

A Tidbit of Info, Though It May Be Unless

Post by dusty »

My Table Height Adjuster was squealing at me when I adjusted so I took it apart and cleaned everything in the mechanism.

When I put the table back on the carriage, I took care to make sure that the Table Height Adjust Handle was at the bottom. Given the gear count previously reported (8/inch), I was going to establish still another relationship to help streamline setup.

Well, that was a flop. I expected that one turn of the Height Adjust Handle would change table height 1 inch. Nope, that did not work out. OKAY, I don't understand gear ratios. Maybe its 2:1 and 1/2 turn will equal 1". Nope, that doesn't work out either.

It's all back together now with no squeal. Mission success.

Residual observation (not necessarily fact): One full turn of the Table Height Adjust will change the table height 2 3/8".

Conclusion: The ring and pinion gears involved here do not result in either a 1:1 or 2:1 change. It is nice to know that there are eight teeth per inch on the riser but that turned out to be useless information. Fact yes, Useless Yes. Well maybe not. I now know that obvious conclusions are not always factual.

The gears inside, Hmmm 16/inch or thereabouts.

My facts cited about were not factual at all. Being prompted by pennview's comment (post #24), I recounted and found 46 teeth in 6 inches. The pinion gear is .906" in diameter. Mathematically, 1 revolution equals 2.608 inches.

I just took some measurements of the table elevation mechanism on my 510 and I found that the teeth on the rack (table upright posts) measure about 7 2/3 teeth per inch (I counted 23 teeth over a span of 3"). For the pinion gear, I counted a total of 20 teeth. So, for one full revolution of the crank, the table rises or lowers about 2.6". Had the rack actually been 8 teeth per inch, you would get 2.5" of elevation for each full turn of the crank.
