My ‘new’ Select 1/2V Milling Machine

[WEL0058]

Sorry Not getting back sooner It’s been of week. Here is measurements you are looking for.

From the wall to tips of front Y-axis handle is about 45”
With X-axis crank all the to right is about 33.5” and to the left also about 33.5”
With belt cover open it is about 72” to highest point with bottom of my base is off floor by 1”. Using a Shop Fox rolling base from Grizzly.
You might add another 1 to 2” for removing the drawbar.

Hope this helps you out. I have small floor space location next to my lathe. The mill was going to stick out about 18” past the lathe. Decide to locate it on the other side of the lathe in a corner. This should work out OK.

Got this mill off CL back in March down the road from you in Tyson Corners next to Tesla car dealership.

Question: I now have a Carboloy R220.69-2.00-16 2" Face Mill with set of ISCAR inserts. Next tooling looking for set of collets to use with hex and square collet holders. Looking at either ER40 or 5C collets. For someone who has neither of these collet types, which is the best to standardized with? Right now do not see using in spindle - just for holding work in place.

Just to update. I just purchased 3x Easson 1um glass scales (GS11 250mm/600mm and GS31 400mm) glass scales from DroPro on eBay at less than 1/2 price they use to list for on their website. Waiting for them to ship. Seems they are focus totally on the magnetic scales now.

Will focus on getting DRO installed with what time I have available.

I have a very similar machine, mine was bought from MSC in the late 80's. Yours is the first one I've seen that is so close to the one I've got.
Mine was acquired from the bankrupcy sale of a local factory, they had a dozen of them, plus several new machines in storage as spares.
I bought one of the new machines in 1991. The date of the invoice from MSC on mine was 1987, they paid $1220 for it brand new..
I bought it then to fly cut VW cylinder heads but its not seen much use over the years. I've done mostly bulk drilling operations with it over the years but its pretty much still a new machine.
I weighed mine when we loaded it at the sale, the dock scale there said 1,071 lbs with the shipping pallet still bolted to the bottom.

I don't use it very much these days but have kept it around for the convenience.
I've been knocking around the idea of trying to get it in my basement where it would get more use. Its either that or sell it and buy a smaller machine that's easier to move around. Right now mine is set up in a corner, the goal was to save space.

Mine came with a rotor type switch on the left side, the switch is shallow and fits into a recess in the casting just slightly higher than the switch on yours. The color looks the same, the belt chart looks the same, and the base looks the same.

My motor is different, it never had a rubber flap behind the table but its got felt wipers on the ways. I have mine mounted on machine pads.
I think the table on mine is a bit larger, I have a pair of old Bridgeport 6" vises mounted on the table, and still have more than half the table to work with other items.

Tooling wise, other than a large set of R8 collets, a larger drill chuck, and two fly cutter heads I never bought much for it.

Well this is my first post in this forum. Have been posting in the Clausing forum...

Bought my first mill this weekend which followed me home on Saturday. Been looking for a ‘A1S’ style milling machine for over a year now to complement my Clausing 100 mk 3 lathe. A week ago this mill was only posted on Washington DC CL for 27 minutes when I found it. Contacted the seller immediately and she agree to give me first shot. The mill is a 1979 Select Machine Tool model 1/2V 7x30” knee mill made in Taiwan with a lot of tooling.

Bought a HF 1T shop crane and a HF 8T air/hydraulic jack. Modified with five foot 2” x 3/16” square tubing the extend the reach and height. My brother and I drove up with his truck and small landscaping trailer. Lifting the 900 lb mill and moving it to loading dock was no trouble. Took an hour getting the mill down onto the trailer. Bolted 2x4x6 boards to mill base and slide mill down 30 degree onto trailer.

The knee raises and lowers smoothly. Lock all the travels and check for backlash with very little movement. Lead screws are adjustable split nuts. Forgot to take any pictures moving it. Have the original owner manual with all recorded QC measurements and inspector stamps. The document S/N match mill number. The quality of this 40 year milling machine was definitely not targeted for the home hobbyist market.

It may be a month or two before I get around the mill.
Select Machine Tool, Model: 1/2V, S/N:64620, MfgDate: 1979

*** Long term ToDo plan ***
1. Fab rolling base with casters and leveling pads
2. Remove/Clean: Bed, Saddle, Knee, Spindle?, Touch up paint
3. ?Convert to 1-Stroke Oiler?
4. Install 3 or 4-axis DRO TouchDRO
- Scales? Glass or magnetic. (I’m using iGaging Absolute+ on my lathe)
5. X-Axis PowerFeed. Servo(USA) or Align(TW)
6. Convert 1 HP 1P Motor to 1.5 or 2 HP 3P VFD
7. Column Riser Block?

*** Additional Tooling ***
1. Quality Kurt-style precision vise. 4” or 5”
2. Precision drill chuck
3. Quality Parallels Set 6” x 1/8”
4. 1/2” Clamping Set
5. Maybe another set of 123 blocks?
6. Indexer?

Does one know the actual manufacture is for the ‘Select’ milling machine? Poa Chuan Machinery (TW), Kao Fong (TW), ???

Hi Bob
Just got mine yesterday. want to install a DRO, hope you got one so I can pick your brain.
thanks

Hi Tony,

That is one nice looking 1/2V mill you got there. I like the way PO mounted the drum switch. Much easier to turn Off/On the mill instead of the original push button switch mounted on left side of the column. Also you have both shelves mounted on back of column. I have the smaller shelve but no threaded hole to attach it. Guess supplied but owner decide were to mount. By the way welcome aboard.

Well sorry not post much this year. This winter was mostly working on my Clausing lathe.

Past year or so ( how time flies by), I have purchase most of major components on my wish list. 1.5 3P motor, X-axis power feed, 3 axis Eason glass scales plus additional tooling.

My priority was the DRO but decide to mount power feed first so no interference when deciding on mounting the Y-axis scale. Have looked dozens of different ways to install the scales. Have decided to mount X-axis in front - more work but did not want to loss another 1” of Y-axis travel if mounted behind. Also tying the Y bracket to mount the Z reader.

The power feed and DRO will be my next fall/winter projects. Bought a rolling base from Grizzly, built Yuri DRO and test Eason scales.

thanks
I totally agree with the front install with the limited Yx . what size in mm did you buy for the 3 xes . think i have the x figured out mounting wise, Y not so much. mine is a extra nice machine i got from a great family, call him Hank
