A good day with mom!!

[ERLover]

I at 63 years young is one of the youngsters here. I am not as SS tech as most, I try and contribute when I can, mostly in WW or as the devils advocate, to somes hatred.
So as mom of 95.5 years young,96 in May, I got her brunch at 11am, her Home Care Giver showed up at noon for her bath/shower, then for the first time since June, over to the public room at the local library for the "girls" knitting clutch till about 330, and she is a Poster Child for them, most are in there 60s -early 70s!!!! Off afternoon for me, went bumming.
Since no shop here till I move some in spring out of storage and make my router table, and few other projects, other then mom, domestics here and cooking, which I love as much as WW, this forum and a few others is my life. So please bare with me if I vent on some or am a bit anti on a subject.
I appreciate all of you here.
Passsed up on a ER for 300$, no SC so not anything special for that price, even if it had one, here in WI a bit over priced.
Love, Mike F

I've seen it a few times, so I've got to ask... What's an SC?

[skou]

Speed Changer.

Common on the Mark series, but a rare attachment on the original
Model 10 stuff.

We have 3 stepped pulleys. And, have to change the belts to get
different speeds. (Unless we have a speed changer.)

The original Shopsmith wanted a whopping 13 DOLLARS for this,
and most people didn't get one.

lilgodwin,
It is not just the ER Speed Changer, it is the coveted ER speed changer!!!!
http://www.vintagemachinery.org/pubs/338/2747.pdf
Page 20 an option to changing pulleys and infinite speeds, they sell for a bout 175-225$ on Ebay when one is there. Heck I will buy a ER if it has one and the seller has no idea for 250-300$ just for the SC. Not to mention the ER is the best SS ever made.
Now in a SS the speed changing devise, sheaves are internal, but to have an ER with one is to be complete!!!!!!

lilgodwin,
here is the difference, on a modern SS the speed range is about 700rpm - about 7500rpm without any speed changing accessories, the Power Prow does what ever you want, but and ER with the speed changer on the low end is 425- about 1100rpm, high end pulleys is about 1100- 7500rmp and the high end numbers I maybe off on, so an ER for a drill press/lathe is so nice.
Here it is, but no speed #

lilgodwin,
do to one of the greats here, JPG just one of many here, here are the # on an ER with a SC, low end pulleys 425-1600rpm, flipped/reversed high end 1850-6800rpm, on both any where in between,variable speed.
If you have an ER without a SC and just the 3 step pulley arrangement here is what you have, 875,1750, and 3500rpm with nothing in the middle.

SKUO,Stevie ER Bro,

Back then I watched my dad heat up a brad nail in a egg beater hand drill over the flame on a gas stove to drill into some oak door trim!!!

Oh ok, well thank you for the lesson, ER!

Between me and SKOU, I am betting you wished you never asked
Glad to answer anything I can, or direct you to you can

FWIW, the top rpm of a mark 5/V is 5200.

......the top rpm of a 10 w/sc is 6800.
