Drum Sander

Would appear a 2" pulley on the drive axle ,,,a 5" pulley on the drum would allow for a desired speed adjustment from the head stock.

ya got me a thinking .

as slow as I am ,,,,maybe by the end of the year .

I have another shoulder surgery scheduled in the near future so things are slow around here.

It might be a over kill..

As a tinkerer,,,, we all ways make things more difficult than necessary ,,

I was thinking about using the bottom drive shaft, putting the sanding drum on the opposite side of the SS , using the pulleys will allow that drive shaft to operate the drum instead of the quill ,the pulleys are for safely slowing the speed down , 3300 rpm is way too fast for what I need, some where around 500 - 1000 rpm max is plenty fast enough for the 4" drum with 80 grit.

I think.

My motto has all ways been
,,,Failure is a by product of experimentation,,

Either I am not following this excursion or there are facts about the top shaft that are misunderstood. The low speed on that shaft is 700rpm (748rpm on my 520).

I drum sand on that spindle frequently.

For some reason I have the impression that the quill bearings wear out,,I have a MKV with a few thousandths ,,5-6 ,,,of end play on main drive ,, since the bottom drive hardly ever,,,in my case,,,, gets used ,, and zero end play,,it would save a bit of wear and tear on the main shaft bearings ,,

I have access to a stand alone planer,jointer ,,air compressor,, so this shaft will probably never be of use.

I think random wishing is a poor substitute for critically thinking things through. But then I may be completely misunderstanding what is intended here.

OKAY, All bearings wear out and not using them under stress will extend their life cycle (MAYBE). However, the quill shaft and its bearings were designed to do what they do. After all, that is the Main Drive Shaft.

Modifying it functionally would be, in my opinion, much more leikely to damage.

I shall watch for the results but I have said about all I am likely to say about the merits, until I see the design.

I cannot help but feel that we have a visionary gap (my vision).

[Hobbyman2]

I enjoy the questions and answers,,, it makes me more in tune with what I am doing or ,,,,even if it is or isn't worth the extra efforts,,,



My original thoughts were ,,,,sort of a stand alone unit ,slide it over attach it to the way tubes and attach a belt and pulley,,,, but like said it I now realize it really isn't necessary to go through all that .

After trying once again ,,I get the too large,, or phpini default .

Am I wrong my computer is in jpeg ?

I am using ,,I believe a program called picasa?

I havent had this issue before to my knowledge ,,so it is all new to me.

My favorite system was win98, since then I havent had time to keep up with the software changes .

I have used the photobucket site for many years , it creates a hyperlink and you can add pictures to the site , it has a very large storage .

I just send the picture to the desk top and log on to the site,, and then up load the picture, its done.

This is probably the same thing if I knew how to configure the picture.

There is a file size limit and with pictures there is also a pixel size limit. Both apply to pictures. The oversize message will tell you which one you exceed. For pictures I don't think it tells you in one message if both limits are exceeded. You may get two errors for a picture. Correct the first one and if you get another error correct that and you should be fine.

I use the picture viewer/editor on MS Office 2010. Just load the picture and resize it to 1024X768 and the pixel size and file size works for the forum. It is like one click in office.

Oh, and don't forget to save the file or else what you are uploading will be the original. If you don't want to overwrite the original then just do a "Save AS".

Thank you

Before I go any further I have to ask are you folks using a camera or a smart phone to take pictures?

Yes. I use both. An Olympic and a Samsung. Now prefer the Samsung s7.

I don't know nut I suspect that the procedures are not all the same between the 4 different Forum configurations. Which ate you using.
