Looks like I'll probably go with the adapter plate. I took the chuck apart and what looked to be a blank back on the chuck was actually an adapter plate fitted to the recess in the back of the chuck.

The plate has 4 5/16-18 holes that the chuck was screwed to with socket heads and 4 1/4-20 holes slightly inboard and in line with the larger holes. Looks like all I need to do is drill and tap 4 holes on the 45 degree radials (the other holes are on the 90's, if you can visualize that, turn a registration recess and install studs and be good to go. The OD of the adapter is already a good snug fit to the chuck.

Any hints for a novice on accurately locating those holes?

There's no problem with the lathe being able to handle a 4" chuck, it's a common upgrade. Some folks have fitted 5" chucks with no problems.

I'd go with an adapter plate; it lets you pass long stock thru & it avoids the risk of the chuck unscrewing itself from its mounting if you slow/stop the spindle too quickly.


Re: Thinking of you.

 

Alan a very good summary in my opinion. Can I also suggest you could go one step further and buy a battery bank, a charger and a DC to mains inverter.
This way you could have a bank of batteries as large as you like you could use a solar panel and turbine to charge it which would reduce costs and still have your mains to keep you batteries consistantly charged. You could also use a de sulphater to keep the batteries in tip top condition.
I have seen 12Volt DC to mains inverters powerfull enough to keep a 6 KW load going. Nothing to stop you using 24V 36V or 48Volt going either.
I would think that a certain amount of filtering and perhaps electronics would be needed to get it all running adequately, but I can't see why it couldn't be done.
Just letting my?mind run with your post really.

By the way some UPS's use what is pretty much a square wave rather than a sine wave. It is actually a squarish wave. Computer's don't seem to mind this!

I think this description could be confusing.?

There is usually some surge and spike suppression built it.? When the power fails, there is a quick transition to running on the battery/inverter.? The output from this is usually a square wave (sometimes deceptively called "modified sine wave."? It's pretty damn modified.)? Some of the UPSs I've looked inside of seem to do some conditioning of the inverter output, some do not.

These work for the purpose--at least in my experience, you can pull the plug and the computer and monitor usually don't blink.? They are about as easy to pick up free as treadmills:? People tend to discard them when the batteries die after a few years.? I have one in my basement, hooked up to a couple of external batteries, and feeding a dedicated computer circuit, the fiber optic interface, router, and a couple of lights.? (If you do this, you need to be careful that trying to charge much larger batteries than intended doesn't overload the charger....)?? (Verizon fiber optic provides a small UPS as part of the package, but it only backs up the phone, not the network access.)

The other sort, as indicated, is always "on."? Rectifying, feeding a DC bus with batteries floating on it, and inverting that back to AC, sometimes a pretty clean synthesized sine wave.? These provide better isolation and no interruption at all if working, but are obviously less energy efficient as you have the constant losses of two conversions.? in some ways they are a lot like a VFD.

The way a UPS works isn't down to manufacturer, there are two basic type
of UPS

1) The simple type where the electronics form a battery charger when the
mains is present but re-configure to form an inverter, to supply power
from the battery, when the mains fails. The output quality is dependant on
the input quality

2) The better type where you have both units present. A dedicated charger
which charges the battery as long as mains is present and a separate
inverter which takes power from the charger/battery to supply the load.
Here the output quality is independent of what the mains is doing and is
solely dependant on the quality of the inverter. These are known as
"online" UPS and provide continuous power without even the slight break
required for re-configuration of the other type. They are, for obvious
reasons more expensive.

{note: some people list the stabilizer function as a regulator or
automatic voltage control }

The voltage stabilizers from APC are about $40 delivered for 1.2kW.
These adjust for over/under voltage and clean it up, but do NOT offer
any battery backup for dropouts.

The voltage stabilizers from TSI Power would be something like $1300
each for 1.8kW.

For filtering, stabilizing, and battery backup if you don't mind the
switchover time, the APC Back-UPS Pro 1500W is about $200 but I see it
says the automatic voltage control is not available on all models
without saying WHICH models. So, this may or may not have it.

I can make you one, if you want. I have replaced that part on all my 7x
lathes with one that will stay aligned. $25 postpaid in the US. I have
also converted the TS on my lathes to lock with an eccentric cam & lever,
and can convert yours, but would need the TS casting here for that, if you

Re: Thinking of you.

 

That's the same as we have, and there is a 10 second auto delay before the generator cuts in, so as to give time to differentiate between a mains dip and a power cut, the genny runs until it is manually switched off when we are certain the power has been restored.

I have an online UPS.? It stands approx 5' tall and

Its current
configuration puts out up to 100 amps at 240 VAC.? When
the mains go out
it will last about 90 mins with my current load.? List
price on this unit
when new was about $25K.? I didn't pay anything near
that, I got lucky and
got it from a liquidator from a dot-bomb a number of years
ago.

I don't run any of the metal working machines from it tho,
just the
servers and CD/DVD duplicator.? During a power outage
the emergency
lighting isn't sufficient to run the shop on the main level
until the
generator is running (which usually doesn't due to
insufficient nat gas
pressure).

I'm running on so I'll stop now.? Hope everyone comes

I've only tried the kitchen oven a few times and didn't notice it lingering but that might be down to the powder I used and a separate oven is a far better idea. People regularly dump ovens when they are remodelling so it should be possible to get one for little or nothing without much difficulty

If you only want to cot small parts toaster ovens are an excellent alternative taking up a lot less space

Hello
I picked up a HF 8x12 metal lathe on Craigslist. It looks new but is missing some parts

My guess is that the tool box got separated from it at some point.

I need both belts. If someone knows the sizes please let me know. Maybe it can order them from Mcmaster.

Both handles are missing for the cross and compound. I can make these, just need some help with dimensions.

No change gears either. I hope someone that converted theirs to CNC would be willing to part with them. Or if anyone knows of a source that may work.

The 3 jaw only has the outside jaws.

The lathe is stamped, 2006 but still has the packing grease on it and was in the original crate. It has all metal hand wheels also.

Any help will be greatly appreciated.

Alan.

Mount your chuck on your drill press, minus the adaptor plate (I assume

you were going to drill into one of the adapter plate fixing holes. The
tapping drill for the mounting hole size should be right and should go in
and out of the hole smoothly, without touching the sides as they say.
Clamp it very securely in position.

Lay the adaptor plate in position on top and carefully drill through with
the clearance drill size, being careful to minimise thread removal from
the mounting hole in the chuck - set your depth stop!

Rotate the adaptor plate 90 degrees till you can get a screw through it to
fix it to the chuck.

Now drill your second hole. Again rotate the plate through 90deg and you
can now have two screws holding the plate to the chuck. Repeat the
exercise till complete. The chuck itself must not be moved during the
process.

Hope this all makes sense.

Re: 4" 4-jaw Union Mfg. chuck

 

Sounds like a good plan.

The registration recess is the important bit; that's what sets the chuck concentric to the spindle. That said, if the chuck is an independent 4-jaw, the work will need to be set concentric to the spindle axis using a dial indicator. Thus, absolute concentricity of the recess isn't as essential as with a self-centering chuck, but eccentricity could cause imbalance and vibration.

According to this drawing:
< > the registration recess should be 55mm diameter, and the PCD of the bolts is 66mm PCD. You may find that the holes on your spindle flange are somewhat oversized, which may allow you a bit of leeway when setting out for the threaded holes in your backplate/adapter plate.

I suppose you might get really lucky and find that your existing 4 1/4-20 holes are at a PCD of 66mm, and that 1/4" (6.35mm) studs will go through the holes in your spindle flange.

There's no problem with the lathe being able to handle a 4" chuck, it's a common upgrade. Some folks have fitted 5" chucks with no problems.

I'd go with an adapter plate; it lets you pass long stock thru & it avoids the risk of the chuck unscrewing itself from its mounting if you slow/stop the spindle too quickly.

Hello
I picked up a HF 8x12 metal lathe on Craigslist. It looks new but is missing some parts

My guess is that the tool box got separated from it at some point.

I need both belts. If someone knows the sizes please let me know. Maybe it can order them from Mcmaster.

Both handles are missing for the cross and compound. I can make these, just need some help with dimensions.

No change gears either. I hope someone that converted theirs to CNC would be willing to part with them. Or if anyone knows of a source that may work.

The 3 jaw only has the outside jaws.

The lathe is stamped, 2006 but still has the packing grease on it and was in the original crate. It has all metal hand wheels also.

Any help will be greatly appreciated.

Alan.

I am pretty sure the HF8x12 is the same machine as Lathmaster's 8x12.? Only difference I can remember is the paint color.? The rest of the specs were the same when I bought the HF a few years back.
