What is being used to make the 7 degree measurement. Which reference surfaces are being used. To make this measurement, I would compare a way tube to a bench tube.

A side comment: I frequently compare the face of the saw blade to the bench tubes, expecting it to be very close to 90 degrees. If you do that with the five locks released and then again with all the locks secure you might be surprised at what you see.

I am using the way tubes to measure it after setting it in the DP mode. I have a sears angle finder that I have used with metal working and it seems pretty accurate. The base looks good and the bench and way tubes seem to be inserted in correctly. I don't see any bent tubes nor does the base look sprung or bent. I sent Shopsmith an email and they want me to pay $19.99 for a five minute call and and $1.00 a minute after that. I will probably end up putting some type of support on the base or at the end of the way tube bracket. I haven't found much info on this site other than what is on this thread. I will continue to search. Thanks Larry

You have two machines that have interchangeable Base Arm Assemblies. Maybe a tear down and rebuild is in order. Swap base arm assemblies to see if the error is moved to the other machine.

I really do not understand how this situation. as described here, could exist in the real world. I mocked up a system so I could see. Here are some pictures of my bench test.

Could it possibly be something like this? :eek: If not, I have nothing else intelligent to offer. If thi.9s is no clue, maybe you need to do a similar set of images,

Pictures can be difficult to figure out how to add, assuming that you are having difficulty with the software and not just unable to find your camera or time to do it. With the recent change in the Shopsmith Forum format, the procedure is now slightly different than when this thread was started. viewtopic.php?f=7&t=19246 The principles remain the same: Before attempting to add an attachment, you probably need to reduce the size in both pixel dimension and overall file memory size. The tab "Attachments" now says the maximum file size per attachment is 3 MiB. I had to Google what is the difference between MiB and MB and learned this: A megabyte is equal to 1,000,000 bytes. One mebibyte equals 1.048576 megabytes. The relatively small difference between the two is, in part, why they are often used synonymously. The previous was 2MB limit. The pixel limits are not given. When I tried to attach a file that was over 3 MB, I received this error message:

Just to try to find the upper limit, I then added a file that was 3000 dpi x 3000 dpi, and just under 3 MB, and it was able to be added just fine.

Pictures of your machine would be a great help to everyone trying to help you figure out your problem.

Ponder the first three images that I just posted. Give attention to the 1.15 degrees and the .25 degrees. Not 90 degrees as you might expect.

If the tubes were at 90 degrees to the base arm the readings would be the same (0 degrees).

When I went to school, a megabyte (MB) was 2 to the 20th power bytes, and it still is. The term mebibyte, and similar, did not exist. The term and new abbreviations were created in 1998 to represent 2 to the 20th power bytes, exactly the same as a megabyte. It seems evident that the term was created because by then the abbreviation MB (more often GB or TB) had been hijacked by hard drive and flash product industries to inflate the performance of their products. For these products, the term MB (equally KB,GB, or TB) does not stand for megabyte. It stands for a million bytes, and normally says so right on the packaging because it is non-standard, but very common, use of the abbreviation. The statement "A megabyte is equal to 1,000,000 bytes" is incorrect, I'm guessing this came from wikipedia or similar. End rant.

However I fear the storage folks are likely more correct.

The term Kb referring to 1024 was a matter of convenience to express a quantity of memory space which 2 to the 10(a meaningful thing when dealing with 10 concatenated bits). But then as the numbers grew the KB was created (B meaning BYTES == 8 bits)

Kb = 2 TO THE 10 OR 1024 !
Mb = 2 TO THE 20 OR 1048576 !
???????
Gb = 2 TO THE 30 OR 1073741824 ?
Tb = 2 TO THE 40 OR 1099511628456 ?

So? GB = 2 to the 23 bits = 2 to the 20 Bytes


YA! Nit picking again.

Y'all know what a shannon is or a nibble? :D

It sure is hard to stay on topic. The least little thing derails the conversation.
