Re: V belt under drive pulleys for 9 in. Cabinet lathe information
A vbelt angle is about 34° a smaller size us different.?
If have under drive is vbelt only.
If have a back motor drive you can use a ploy v belt that is a 40° angle.?
I did a ploy belt to a 9A about 40 years ago and put 1 hp DC motor . Did not need to move belt very nice.?

Re: V belt under drive pulleys for 9 in. Cabinet lathe information
Many years ago in the files section of one of the many south bend related yahoo groups there was a drawing of a v-belt headstock pulley and discussion of groove angle etc.
I though I had archived that info, but apparently not.
Anyone remember seeing it?
Thanks up front

Re: Is 1/2 HP really enough?
I posted a video over in the Facebook thread that Eric has going on the same question. ?In the video I made yesterday, I turned .100” depth of cut, no issue. ?Have a look.
|
Re: Is 1/2 HP really enough?
This only works if you sharpen your cutting tools according to the book using HSS.? That depth of cut is viable but the spindle RPM's are very slow and possibly the back gear is used.??
I have a HSS cutter ground up just for roughing, taking up to 1/8" depth of cuts.? Generally don't use the back gear or cut on anything over 1-1/2 in diameter on the 9" lathe.? I have a 15" lathe for the bigger diameters to be cut on.? That lathe just says feed me more!

Re: Is 1/2 HP really enough?
Cuts like that are for roughing materials for production work. If you're doing production work it's good to have that capability. Maybe even if you're not doing production work, if your shop time is very limited. :) But that isn't appropriate for fine work. So you should set your depth of cut for the kind of work you need. As they say, it's harder to put material back on than it is to take it off. Only you can determine what's appropriate if you're in your own shop...
I have never done production, so my needs are going to be different from those of a guy who is doing production. And I piddle around trying to get the very best accuracy I can manage. Someday maybe I'll be good enough at it to take my ability for granted. Today ain't that day, though! My Heavy 10L is vintage 1941, and was shipped from the factory to a government armory toolroom with a 3/4hp single phase motor. I expect they wanted excellent accuracy and best productivity...

Re: Is 1/2 HP really enough?
I agree , when i got my 9A it had a 1/3 or 1/2 hp motor & I
never had a problem bogging the machine down . I took some very
heavy experimental cuts? way way heavier than .020 just feeling
out the machine & never had any issues . Have you dried to see
what it takes to bog just the motor down ? Maybe put some pressure
on a 2x4 against the motor pulley & see if it slow's it down
?? Have you done the spindle adjust with the rod through the
spindle ? Do yer bearing caps get hot when using ?

Re: Is 1/2 HP really enough?
Nice looking 10K!
Mine came with a brand new 1 HP motor (it had been 3 phase) and
it really struggles to make a 20 thou cut too. But the problem is
in the flat belt, not the power of the motor. When it bogs down it
just throws the belt off the pulleys.
Does your motor stall on heavy cuts or is one of the belts
slipping?
The 1966 SB catalog that I have seen lists all the motor options
as being 1/2 HP.
Lots of factors can affect depth of cut ability. Material,
cutter, RPM of work and feed rate.
A flat belt upgrade is on my to do list. I know that all the
power available is not being transferred to the spindle. In the
mean time when hogging off material, I find the fastest removal
rate that works by experimenting and then just accepting the extra
turning time. It's all enjoyable to me and way better than when I
didn't have a lathe...
Turning scrap parts into pounds of chips and killing cutters if
half the fun!

New to the group, just picked up my first SB (1952 10K) which came
with a 1/2 HP Westinghouse motor. Not sure but motor at least
looks original. Anyone know what these machines came with new?
Poor thing is struggling to take even a 20 though cut. Is it
possible that something is keeping it from making full power?
Start cap starts it right up, but not sure if the run cap could
possibly be causing a problem. Any help would be appreciated.
Machine was in pieces when I found it a few days ago, here' s a
pic..

Re: Is 1/2 HP really enough?
1/2 HP should be well enough power to run your lathe.? My 9" SBL originally had a 1/4 HP motor on it.? It finally died and replaced with a 1/2 HP DC PM motor.??
Tow things that come to mind is, how tight is the flat belt?? Too tight it will draw down the motor.? Next what kind of cutting tool are you using??
How free does the spindle turn with the flat belt disengaged from the sheaves?

Re: V belt under drive pulleys for 9 in. Cabinet lathe information
And of course you will need a segmented belt for the under drive with the V-belt sheaves.
Used on my horizontal for convenience. I haven't cut the UMD flat belt yet, but I have pulled the spindle for inspection and cleaning...

I need information concerning the difference between the v belt
outdrive pulley on a 9in. tool room cabinet model and the outdrive
v belt pulley on a 9in. horizontal lathe. The part number is the
same on the spindle cone pulley for both but the part numbers for
the outdrive pulley are the same except the tool room cabinet has
a 1 on the end and the horizontal has a 2 on the end. I have a set
of v belt pulleys from a horizontal but I really need to know if
there is any difference before I start the tear down to install

Re: Cabinet to mount lathe
Rubber and plastic wheels have a tendency to get flat if not
rolled around very often. Some are better than others but they are
all probably over rated weight wise. I like to go bigger as they
roll easier on my not so smooth floor and they are rated higher
too.
For heavy things that I want to roll when needed but will
probably sit in one spot for a long time, I like steel casters.
Cost more up front but shouldn't need replacing. In theory at
least.

years ago, and that may yet happen, but I've only got enough
for the one workbench. And right now, my shop is too cold
