No, I think Yota is referring to the regular manual. It’s list the part codes are SCA-64 and SCA-54.

Yes, I was referring to the SM manual, just left off the SCA from the part number. My pulleys measured out to 6" on the spindle and 5" on the motor.
I'm going to try the StrobeLight app to check the rpms and will let you know later.

I pulled my pulleys this morning.

The motor pulley is marked 5-4-3-2 and the spindle pulley is marked 6-5-4-3 which corresponded to their over all diameters.

Using the tach I got 65-105-180- 290 in low range and 300-570-870-1400 in high range.
The face plate is marked 50-100-180-300 in low range and 250-500-900-1500 in high range.
So close enough.

Check your motor rpm IIRC it should be 1725. If the motor isn't reading 1725 with the belt on then that will give you a different reading as well.

Tach indicates 1785 on the motor pulley.

$13 when I got it. Not sure how much I actually trust it. Takes some fiddling to get the readings to settle down.

 

[YotaBota]

Using the StobeLight app here's what I read;
Rated Actual
50 - to slow for the app
100 100
180 177
300 275
250 235
500 500
900 878
1500 1505
The motor with the belt on 500rpm config
1725 1790

Even with the motor running high the spindle speeds are close enough.

 

[Emery]

Okay,

I did the strobe light test as well.... (so cool!!!)
selected speed - actual speed
50 - 105
100-254
180-415
300-702
250-521
500-1100
900-1926
1500- I didn’t want to run for a long time to figure out RPM but by my calculations it would be around 3450.

Soooo... I am quite fast.
Anyone know where to buy these 4 step pulleys?
Edmonton preferred but I’ll buy online if not =)

Thanks for all your help guys! I would have struggled with RPM for a long time before i figured this out!!

WOW That lathe is looking really good. Looking at the items you got with it you did well.

Threading dial indicator
Steady rest (home made, not OEM)
Follower rest
Face plate
3 and 4 jaw chucks

The stand is a nice to have for sure.

Do you have the taper attachment?

Going to share what you paid for it?

Put your 5" pulley on the spindle and 4-1/4 pulley on the motor and test it again. That should swing you back to reality. If that ends up close, a 4" on the motor and 5" on the spindle should be the same as a 5" and 6" set (I think???). I can help you with a 4".

BTB - I have some parts, mostly apron stuff if you find you need to replace something.

Thanks Craig! I’ll keep you in mind if I need parts. (I need a pulley hahahah) It’s GREAT to hear that you think I got a good machine. No taper attachment though... that would be very cool to have.

I’ll swap the pulleys and see what RPM’s I run. I’ll amp make the fastest setting away from the machine. I’ll think about you 4” option. Is it a 4-3-2-1?

I just measured and I do have the stock 5-4-3-2 pulley. So I need to replace my 4 1/4 inch with a 6-5-4-3. 5/8 shaft.

What RPM does you Electirc motor put out? I thought this was supposed to have a half horsepower motor on it but mine is 3/4 @ 1725 RPM.

Of course I can share the price. I picked it up for $900 and payed the farmer another $50 bucks to load it with his picker truck. I think that was good price... =)

 

[YYCHM]

Mine came with a 3/4 @ 1725 but I ended up replacing it with a 1/2 @ 1725 due to a vibration issue.

You got a good deal considering the stuff you got with it. I paid $950 for mine with no stand. It was missing the threading dial indicator, follower rest, dog drive plate, face plate, 4J, and the gears required to delete the height extensions. It did come with 98% of the taper attachment.

I think you did good with the machine as well, nice cabinet, it looks like a factory follow rest and a big faceplate also. That is a huge 4 jaw chuck, be careful opening up the jaws that you don't whack the ways with a jaw.

YYC - do you know where the pulleys are from the donor lathe?

I do most of my turning between 500 and 900, parting at 250 and threading at 100 so your still very usable as far as speeds go, keep your chart handy for reference.

You turn about the same speeds I do LOL.

I got the pulleys from the donor lathe and used the motor pulley to replace my pooched motor pulley (don't run those things without the keys installed!). The headstock pulley was a 3 step, why I don't know, I gave it to @johnnielsen for a wood lathe project he had.

Mine seems to make more noise in low range than higher range especially in the two fastest settings. But I think this is because both those settings are exceeding the low range RPM.

Thanks for the advice on speeds. I’ll add it to my book of information. I’m going to start actually using the lathe this week. Now that’s it’s cleaned up!

Thanks for the advice on opening up the 4 jaw as well! I just checked how much I can open it and it will definitely hit the ways. It had to be almost all the way open but good to know!

Here are some fun before and after pictures!

Welcome Emery and great work cleaning up the lathe.

Your 180&300 are running way over speed which is probably why the are noisy.
To help protect the ways in case of an oops, I have a board that covers the ways when changing chucks. It's just a piece of plywood with a 2x4 ( cut to fit in between the ways) screwed to the bottom but helps. That's if it will fit under the 4 jaw, lol. BTW, what is the dia of the 4 jaw?

Hey Yota, I agree I’m not running 180, 300, 1500 right now. David helped me find a pulley so I’m going to order that right away and swap out the four-inch pulley.

As for the 4 jaw it’s an 8 inch! It’s quite large but it works great!

I did my first thread today also... picture below.

 

[YYCHM]

8" 4 Jaw And here I thought my 6" looked big.

Where did you find a pulley?

Nice work with the threading.

 

[YotaBota]

The right pulley will make life a lot easier, thanks David.
Let's see,,, 9" lathe,,,,8" chuck,, you've still got room for a bigger one lol
Did you do the "Holy Sh_t it works" happy dance after the thread. As long as you don't get the cross slide and compound movement mixed up threading is easy....ish
Well done.
