GRIZZLY SIZE ETC???????

[riversidedan]

just aquired a small grizzy lathe and cant figure out the size .........I had a smallist one awhile ago but its been sold , am thinking this is one size up from the smallist one just dont know......??

also when I got it the rust had set in , its not pitted just surface type so sprayed it with rust inhibitor and used fine sand paper acrossed the surfaces...........seemed to clean up but can still see the stains, but thats the least of my problems ..........

Next feat is firing this thing up , as you can see the wires hanging out and assuming the black/white is the power and the other blue /white have something to do with the missing power panel................its also missing some parts that can be had from grizzly or maybe someone out thier has them ??>>>>>need your help on this one guys

Measure the centre of the spindle to the top of the ways (lay a steel rule across the FLATS of the ways if it falls over the opening between the ways, makes it easier to measure) then multiply that number by two. That measurement is your "swing". (if you have 3-1/2" to the bedway from spindle centre, then the "swing" is 7")

Remove the chuck and place a dead-centre in the spindle (the bit the chuck was mounted to).

Slide the tailstock right to the end of the bedway and fit a dead-centre to the tailstock quill ensuring it is locked in, then slowly wind the quill in until you feel it stop.

Measure between the tips of the centres. That is your "Between Centres" bed length. (For example 12" between centres)

The size of the lathe will be "Swing inches X between centres inches" using the above examples, that would give you a "7 x 12" lathe.

Looking at your photo's, I am inclined to think that it is indeed a 7x12 model of an Asian mini-lathe.


BTW, Blue & Brown wires **should be** "power in" to the "e-switch" on the control panel, white and black **should be** motor power from F/O/R switch.

Do NOT take my word for it and CHECK where the wires lead to/from.

looks to be either a 4x7 or 4x6 could be either one.........now for the power wires but just ran across this little marvel that could replace the factory speed control but still need to find out about those loose wires..............https://www.ebay.com/itm/285826022184

Are you sure you measured that right? there is zero chance that is a 4" swing lathe, it would be a heck of a lot smaller!

To get "Swing"



To get "Between Centres"

 

[riversidedan]

You sure you have measured that correctly?

sure looks like a 7 to me.......but again am more concerned with those wires and that speed control I just ran across here>>>> https://www.ebay.com/itm/285826022184

BTW the smallest grizzly lathe I sold last year did not weigh as much as this one!! so its gotta be the next size up..


if I multiplied the distance between centers x 2 then that would be 14 cuzz it measured 7 between centers....
OK so much for that.........now on to the wiring business

Check the images in my prior post and confirm your measurements....

A lathe is measured swing first, then between Centres, Id-est with no chuck fitted. For example 7"x16" (7" swing, 16" between centres).

If that is a 4"x7" it would be in the realms of a watch makers lathe and it is not. The chuck* alone looks like it is a 4" (100mm) one, so given the space between it and the bed, I would say it has a 7" swing (3-1/2" from centre line of spindle to top of ways).

* = Chucks are measured by diameter

Let's see what kind of motor it has- ac or dc and HP rating or voltage
Don't buy the Ebay control you linked to- chances are it won't work well

That’s a 7 x 10. White, black and green are 120v in and black and blue are 90vdc to the motor. I think
