Re: Mounting PVC Fitting for Boring
¿ªÔÆÌåÓýElectrical grade PVC pipes have even
longer radius sweep ell's if you have the room...
They can even be 'STREET' style and can
be had at Home Depot and Lowes, (and others in your area).

Re: Mounting PVC Fitting for Boring
If you have room? for it, a sweep elbow would be a better choice than a standard elbow.

I'd probably do it on the drill press, but to keep it a lathe project, you could mount the elbow on the carriage & use a boring head or suitable hole saw chucked in the spindle.

Re: Mounting PVC Fitting for Boring
You are correct.? However, I will still be able to use my lathe.? The 1 1/2" pipe will need to be bored to fit both the tool port and the vacuum hose end.

Hi Mike. Personally I would take the easy route and use short pieces of plastic pipe bored etc to suit and connect all together. One piece to fit dust collection port, other end to fit 90deg fitting, then the next piece from the fitting, other end to suit the vacuum hose. As short as possible, shouldn¡¯t take up too much extra room. ????????? Ellis ? ?

Re: CJ0618 lead screw
I decided to go ahead and get an imperial lead screw for my lathe.
I looked around and could not find the imperial leadscrew for a cj0618 on AliExpress or Ebay.
Only the 1.5mm screw was available. However, I did find the 16TPI screw and half nuts on Grizzly's?
site. The price was pretty good (about $86 US) and it shipped for free. I will be getting that in
a few days.?
?
Thank you all for your suggestions and comments.

Re: Mounting PVC Fitting for Boring
¿ªÔÆÌåÓýTurn the jaws around first . Then I would drill a hole through the 90 centers with one of the openings & run a piece of all thread or a long bolt through the spindle with a washer & a nut on each end I think that the jaws would just keep the 90 from moving , not sure ya will be able to get much clamp pressure that's why I suggest the bolt/allthread . Ya don't need much speed to get this done . Ya could also? cut one side of the 90 off & glue the original bored part to the 90 with PVC cement . animal On 10/24/24 12:55 PM, Arthur Coe wrote:

Mounting PVC Fitting for Boring
I've got a 70's era radial arm saw with a dust collection port that doesn't match current vacuum fittings.? I bored one end of a 1 1/4" PVC coupling to fit the saw outlet and the other end to fit the vacuum hose.? It works, but for long term a 90-degree fitting would be much better.
?
I have a 1 1/4" PVC 90 that I would like to bore out to do the job.? However, having trouble figuring out how to mount on my 3" 4-jaw chuck (see photo).? I need to mount so the opening(s) is centered on the spindle so the 4-jaw adjustment capability would be great if I could get it mounted.
?
Any ideas on how to mount? |
Re: Motor Cuts using Steady Rest
It¡¯s a LMS 4100 upgraded to a 16¡± bed - it has a brushless motor. I know it has an over-current cut-off and that¡¯s what¡¯s kicking in. What I can¡¯t figure is why I¡¯m might be over-feeding with a 0.010¡± cut with the standard lead screw rate of 0.004¡±/rev. It seems to cut-out less with Tap-Magic vs WD40. I tried 350-700rpm but the rpm range doesn¡¯t seem to matter.
?
Might it be the tool is forcing the rod towards the rear steady rest finger and the friction goes up too high?? |
Re: Motor Cuts using Steady Rest
Which 7x16 is it?? That doc is for the older Brushed DC motors.

If it's a BLDC 7x16 it'd be a different drive and motor... On 10/20/2024 7:12 PM, Roy via groups.io wrote:

Re: Motor Cuts using Steady Rest
Is it only when using a steady rest that this happens? You probably need to check the amps. On Sun, Oct 20, 2024 at 4:05?PM CBJessee-N4SRN via <cbjesseeNH=[email protected]> wrote:

Motor Cuts using Steady Rest
The motor on my LMS 7x16 cuts out turning down 360 brass when using a steady rest with a HSS tool. The 7" 1.25" brass rod is centered in my 4-jaw cuck to 0.005" and the Steady Rest is 2.25" back from the end. I'm using reversed Emery Cloth under the brass points with liberal and frequent oilling. The rod turns by hand w/o much friction. Cuts deeper than 0.010" stall the motor when the lead screw is engaged.

Thoughts appreciated! |
Re: CJ0618 lead screw
The I purchased last came with metric lead screw 2.00mm?
?
I do most time both inch and metric with dies.?
?
If doing projects that needs both inside and outside threads I just 2.00, 1.00 or 0.50 mm pictures.? I do not use a thread dial.?
?
It is easier to metric pitch?
When I was doing machine work I did not have choice?

Re: CJ0618 lead screw
I have a handwheel not a crank so it no problem with power reverse.? I have cut many threads this way.? On Fri, Oct 18, 2024 at 4:49?PM Roy via <roylowenthal=[email protected]> wrote:

Re: CJ0618 lead screw
The problem with cutting threads of a system different from the lead screw is that the gears can't be disengaged & re-engaged in the same position. You have to keep them engaged the whole time and retract the tool when returning the carriage for another cutting pass. With a hand crank for more low speed torque, a power return can be a little exciting ;-)
