Bridgeport Project

It’s funny @RobinHood how we think alike.

they do make 145TY- 4 x 240 volt motors without the base plate and a shaft adapter where you fit the output shaft you need. I had that site and lost it. Trying to find that again.

trailer is loaded as are some accessories for tomorrow. Hopefully #1 son in tow for chain fall operations.

I will offer up my opinion on the whole mill tomorrow after we get the mill back to @architect. If I was retired, I would have bought it as a project anyway.
 
This is a bit different, but seems to work...

Wow...... I'm impressed at the sheer ingenuity and the willingness to even try such a small motor.

But what really caught my eye is that stone wall!

I visited the link and I learned something new that the rest of you already knew. I feel kind of stupid, and it might be obvious to everyone else, but never underestimate what a green horn doesn't know. That reminds me of another great saying I love - "You don't know what you don't know".

Anyway, I have been busy looking for two speed motors and can't seem to find them. Yet both of my mills have a hi and low speed switch on the motor. So obviously, they are two speed....... Apparently NOT!

It turns out that the switch is actually a forward/reverse switch and it is used in coordination with the back gear! I would never have guessed that on my own!

The search for a motor just got a lot easier!

Now if only I could find a chart of motor mount and shaft dimensions......

Oh yes, beautiful stone construction.

Here are two electric motor frame charts for reference:

and

That's awesome info!

Thank you @RobinHood!

I actually looked on the emotor website but didn't see any charts like that even though it's exactly what I was looking for.

Thanks so much for that!
 
Took about 4 hours but @Brent H is a genius and three of us muscled the Bridgeport nto the back of my tiny garage. I'll need to spin it around 275 degrees but saving that for another day as I'm exhausted and need to make up for skipping work today!

Some dicey moments that couldn't be captured. Photos show all the good moments where I'm able to stop and take a photo. Brent had a wench tied up to the back of trailer to slowly release the mill down the ramp. I'm not going to pretend I wasn't nervous lol I'm sure Brent was fine with all his experience.
