I wanted to make a ceiling fan out of a prop, but never got around to it.

I trust you know what a Pitts Special is?
We now own the Big Hickey Curtis built for himself to travel between Pa. and his factory in Florida.
Curtis never finished it, but we got it airworthy about a decade ago.
It is very fast.
I have some time in a PA-28-140 and have the prop off a 180 hanging in my livingroom.

Re: Projects ,on ,mini lathes,

 

There's a definite advantage to machines that were designed to work in less than ideal conditions.? When we moved here everyone expected us to buy a BMW or Toyota but we bought a Lada 4x4 SUV.? Our friends now call our car The Tank after seeing me drive/swim through mud and potholes that would swallow a lessor car.

I tend to design stuff that will work in less than ideal conditions.? One of the TV studios declared our lighting controls to be the gold standard that new stuff had to compare to.? I'll bet some of our stuff from a couple of decades ago is still in use.

For a consumer lathe, plastic is probably fine.? I never changed the gears in mine and didn't have a problem.

Metal is a lot nosier, not good for consumers putting these in a spare bedroom with the spouse watching TV in the other room.

My new lathe has all metal gears and a 3 phase motor with a dedicated VFD.? Motor quiet, gears are a bit noisy but not bad.

My old mill was belt drive and pretty quiet.? An old Taiwan "tabletop" I bought in the late 1990s.? The new mill is a gear head with a 2kw 3 phase motor and VFD.? Motor is pretty much silent, but the gears are anything but.

While I'm on motors, I brought our horizontal bandsaw from California as it cuts dead true.? I left the 120V motor and stand behind and built a new stand for it here.? A friend here gave me an OLD Soviet 3 phase motor that had been rigged up with capacitors to run on single phase and it had a grinding wheel on it.? Looks funky but runs fine.?

I got the grinding wheel off with penetrating oil, tossed the capacitors, machined a pulley hub to fit the motor and now I have a nice band saw.? Have to finish hooking up the auto shutoff and hydraulic lowering system but for now it works with a manual power switch.

Handy that I have 3 phase power in the shop sort of by accident, they brought in 3 phase to power our sauna as single phase power draw here is limited to 25 amps for an entire house. I said HEY, put a circuit in the shop!? They left the wire hanging out of the wall and I added a sub panel to that and it powers the mill and band saw.

Bandsaw right after we got it working again below

Hard to see plastic gears on any lathe?
I forgot part to watch out for.
As it is the gears I have on my lathe are power metal gears.?
?
The spindle bearing very a lot some are class 1 all the way to class 8 and do not till you. Most are 6206 ball bearing no seals. It same bearings I use on hangar doors seal class 3 or better.?
?
It just things that can fix easily and for under $50.00 at manufacturer cost they would have great lathe

Here's the other mods I did to the Grizzly before I moved.

Gear and leadscrew covers, wider stance on the feet.
Re: Grizzly 7x14 owner

 
Edited

I guess I should clarify the stuff about the shop in Brownsville Pa. USA.
That is an oldschool lineshaft shop I run out at our Steam Gas and Horse Association showgrounds.
?
I am deeply involved in the preservation of our equipment there and do all of the needed repairs when necessary.
The most difficult part of that is preserving the century old patina that the old girls now wear since clean and shiny isn't always in their best interest.
?
My home shop is fairly well equipped, but I also try to do as much of the work at the showgrounds just to be able to say that all of my old "girls" help each other there instead of taking the work outside of that setting.
Re: Grizzly 7x14 owner

 

In all, I was kind of disappointed with the machine because it would have likely ruined a first timer's experience with it since it required some attention from square one.
My original intention with it was to re-sell it, but afterwards I decided to hang onto it since I would have lost all of my time invested in it just to make it a feasible machine.
?
With a little work,? new owners can make the mods needed to them over time which could be some very nice projects to add to their lists.
?
One more mod I want to make is for the protractor on the compound rest so it will allow it to be set at 29.5 degrees for cutting 60 degree threads.
At the present, that option isn't available on the Grizzly since it isn't within the range of it.
?
Eventually it will be headed to the oldschool shop in Brownsville to use for smaller work and polishing.
?
A huge upgrade to them is the metal gearsets that are now available on Ebay for under $100.
My set included the headstock gears and the cog belt gears for the drive assembly.
When I pull the spindle again to replace the plastic gears in the headstock, I will add the necessary provisions to properly lubricate them.
?
Re: Grizzly 7x14 owner

 

I never took any images of my motor mount mods, but the difference on mine was the counterbores in it that allowed me to torque the plate to the studs prior to mounting it.
?
I matched the radius of the motor to my plate so it was cradled which added rigidity to the final assembly.
?
When I got the lathe, it was on a horse trade and was inoperable because the former owner had tried to shift between high and low range while it was running.
One more mod I intend to do to it is to add provisions to lube the headstock gears since there was none from the factory.
?
When I get a chance, I will provide a detailed photo of the leadscrew thrust adjuster I made for mine.
There were necessary mods made to the leadscrew reverser to properly clearance the fits on it too.
?
I still have the three jaw chuck it came with, but since I already have ER32 stuff in my shop, it was a natural to equip this machine with the collet chuck.
?
Our Diamond 22 horizontal mill in the lineshaft shop has a Brown & Sharpe #9 taper spindle that I fitted with a brand new import er32 setup since the B&S tooling is starting to dry up.

Here's the mount I made for my Grizzly.? Sounds like we were thinking alike.

An OXA quick change toolpost was a must have for me and I outfitted it with narrow nosed live center.
The end thrust setup on the leadscrew was janky, so I machined a nicer setup for it.
I was very disappointed with the drive motor mount, so I made a radiused and counterbored flat plate to mount it.
I cleaned the casting pimples off the mounting area and made thicker stepped washers in order to give it better support.
In the end, I had to modify the splash pan a little to compensate for the added dimension of the plate, but the end result was what I was after.

Re: Projects ,on ,mini lathes,

 

My father had a couple of planes before I was born, but I never got to see them other than in pictures.? He had a Piper Cub for personal use and he also joined with a couple of other guys and had a C-47. They used that for air freight and some tax free moving of sugar from South America to a big hotel in NY during the war.

He taught me tool use, and to repair/make things you need as well as keep an eye out for valuable trash.? He grew up on a farm so that was how you did things.

Re: Grizzly 7x14 owner

 

Looks great
Before read a lot of reviews on different lathes and some had for different brands.
I do not help you at this point.
?
This first time mini lathe since Nov 2023.
Before I had larger lathes?
I thik this about correct size for most home work shops after a year.
?
The reviews complain about noise on some model , no quick change , tool post. So went to ploy-v and has a Aloris tool post since 1970’s and a DC motor I plan for power feed later.
On mine I add extra long cross slide trave?
Temperature gauge on the motor?
STEADY REST
?
Over all other few this manufacturers did not complete it good little lathe.?

Grizzly 7x14 owner

 

I have a Grizzly 7x14 that I fitted with a ER-32 collet chuck.
It was improved with a steel gearset and I "fixed" a ton of things that were machined wrong on it to make it more suitable.
An OXA quick change toolpost was a must have for me and I outfitted it with narrow nosed live center.
The end thrust setup on the leadscrew was janky, so I machined a nicer setup for it.
I was very disappointed with the drive motor mount, so I made a radiused and counterbored flat plate to mount it.
