thanks

Re: Oscilloscopes

 

Certainly not lab grade but functional and likely very handy. ?I have the FINISRI tablet. ?Most of the use is just to see if there is a signal where rough measurements are fine, with frequencies below a few MHz,
?
There is a newer one on Black Friday special that looks even more useful.

hey folks , so I'm startin to get a bit more serious bout buying a new
oscilloscope . Does anyone have any experience with any of these Hanatak
, Rigol , Iwon , FNIRSI or the like ? I'm also lookin at some of the 100
MHZ Tek TDS scopes . MY newest scope is a Tektronix T922 with a dead
channel . I really like the size of these newer scopes I mentioned .

Also whats a good contact cleaner ? I figure I'd at least try
cleaning the contacts to see if I can revive that 2nd channel . I hate
to have to resort to my 1950's round CRT Heathkit scope ( though it's
the only one out of 4 that work )

Re: FW: [SouthBendLathe] DIY power feed for mill ?

 

Can one use the?direct drive motors to position the table accurately? With a stepper I know the position but wonder if on-off gives you precision.
Would you use the motors for CNC?

Titon Eng CA produce a Super starter and there original motors were modified for various NASCAR cars using this motor,?
sourced from Datsun Canada. Today possibly available and cheap from car scrap yards.
This is a gear reduction motor, brushed so RPM changes are difficult, but with plenty of torque.
I believe physical size was about 5" dia x 8" long.?
The guy basically drove it off a 12V battery adjacent to the mill.?
Being it a starter motor the drive pinion only entered the gear attached to the original mill bevel gear arrangement when the button was pressed to excite the motor, so manual operation?of the knee was always available.?

Re: Diy Powerfeed for mill

 

¿ªÔÆÌåÓý

I bought mine from House of Tools here in Victoria before they vanished.? It¡¯s equivalent to the Grizzly G3616 which has the smaller table? etc. compared to the G3617 which also has the horizontal spindle.

?

Grizzly tools has discontinued even referencing this mill.? Used to be able to enter in that number and it would come up with the info about it but state it was discontinued.

Here¡¯s the spec sheet.

?

But there is a way to it

?

Under Product Linksyou can get the parts list and manual.? Way better than the one from House of Tools.

?

On the Bergerda site ?if you ?ask your question in this little box odds are it will be Donald Chen who responds.? I¡¯ve found him to be very helpful.

I¡¯m now running Bergerda AX Servo¡¯s on all axis with the exception of the 4th Axis Harmonic drive which has a 3 phase motor but a different Servo Driver.

?

Bergerda does make a lot of motors for the sewing industry.? One time when I was having some tuning issues their engineers made a quick video using a cell phone and sent that to me to help me out.? Great support!

??? When ya say servo , are ya talking like one of those Consew sewing machine servo motors ? I had forgotten all about those units .

Here¡¯s a photo of the original parts.? Thrust bearing at the bevel gear end set the end play.? The shaft sat in the cast iron and there was dramatic end play but then it was designed to be turned slowly by hand.

?

At the gear end the thrust bearings pressed against the gear and the cast iron.? I replaced the cast iron side with an bearing instead of a bushing.

?

At the crank end I replaced the bushing with bearings and spacers and took out the end play to the bevel gear.? Now I can spin this to get 150 IPM on the knee which is scary fast.

?

First trial was with a 650 oz-in stepper motor with 4:1 reduction.? If I was lucky I got 10 IPM before the motor locked up.? Stepper motors cannot turn fast.? Changing to a 1200 oz-in motor gave me 25 IPM and that worked until the GECKO controller developed corrosion on the terminal connector and failed.

?

From there I changed out the motor to a 750W AC Servo good to 3000 RPM and now have 150 IPM.

?

Eventually I¡¯ll drive the vertical screw directly to reduce backlash but for now it¡¯s been pretty good.

Hit send too fast . The knee is the one that I will probably convert first . I had my chest cracked 7 years back & thinks like raising/lowering the knee reminds me that that work\was done to me . I have one of those electric seat motors , but i don't think it has enough power for this . I think my next plan is to remove the table & go down to the knee mechanism & clean, lube & adjust my way back up to the table .? I would be interested to see how ya / yer bud did the Stepper? & DC motor install .

thanks

??? Sorry Forgot to mention , ye it's a knee mill I was told it was purchased new in the 80's . It Came from KBC tool's . I got it from the original owner whose work was 95 % plastic , no steel & some aluminum . He made some kind of optics stuff .

Does your mill have a knee or does the head assembly move?? That's easier than moving the quill and leaves the quill as a manual option.

There are all sorts of ways of doing this.? For the longest time I had a stepper motor on the knee shaft that I ran from one of my ELS units.? I could set zero where I was milling and then if I wanted to do a 0.010" cut just move the knee by that distance.
?
A friend of mine with the same type of mill just added a DC motor with a variable power supply and a couple of toothed belts and uses it to avoid major tedious cranking operations.
?
Or, start thinking about CNC now and start the conversion.? Just do the Z axis to start.? Whatever controller you use add a pendant with an MPG and now you are on the way with adequate control.

 ? Finally got my mill in my machine room & under power . Wondering if
anyone here has come up with a DIY powerfeed that could be used on a mill .

Re: FW: [SouthBendLathe] DIY power feed for mill ?

 

I have seen years ago, a Bridgeport clone mill Z axis column power fed with a Nissan? used to be "Datsun 260 "cold weather starter motor.
Titon Eng CA produce a Super starter and there original motors were modified for various NASCAR cars using this motor,?
sourced from Datsun Canada. Today possibly available and cheap from car scrap yards.
This is a gear reduction motor, brushed so RPM changes are difficult, but with plenty of torque.
I believe physical size was about 5" dia x 8" long.?
The guy basically drove it off a 12V battery adjacent to the mill.?
Being it a starter motor the drive pinion only entered the gear attached to the original mill bevel gear arrangement when the button was pressed to excite the motor, so manual operation?of the knee was always available.?
Cheers
