My ‘new’ Select 1/2V Milling Machine

WEL0058 said:
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), ???

Heya Bob,
I know this post is a year+ old but I just got my hands on a Select 1/2VB and wondered if you have or know of a illustration manual for these units.
I think I will be replacing the spindle bearings soon and want to see if any P/N and or teardown info is available.
Nice lot of tooling you got with your unit

Hi Seeker - Welcome aboard.

If you go to page 2 of this thread, I posted my mill manual. Found the Grizzly G1004 mill is almost 100% identical. Grizzly is the best source for mill specific parts.

Do you have any pictures?

Do you see any difference between my mill and yours?

I used my mill a lot this make parts to mount an iGaging DRO on my Clausing 100 lathe’s cross slide.

What is the issue with your spindle bearings? There was a thread in this forum someone who was doing a complete breakdown of his Grizzly mill including remove and disassembling the spindle.

I found it after being blinded by pop up ads and looking at page 2 closer I downloaded it about 2 hours ago.
Here's some pics. I've been cleaning and lubing. When I lowered the quill I should see through the front housing the top, lower bearing exposed, non-sealed. It was dry. The drip luber on the unit had oil in it but not sure it fed the quill bearings on just the sleeve plunger.
This unit is a little different than your unit. The motor (I don't think it's the original) is mounted on top. It came with a VFD to power the 3 phase motor with single phase 220 VAC.
I'm tooling up all that I no longer have access to. eBay has supplied a lot of good deals. I've sold and bought on eBay since 1998. Back when you needed to know html to write an auction. Much easier now.
Been 2 years since relocating from WA, leaving a 15 year career (covid) and losing access to the companies machining equipment and tooling. Went into machining withdrawal!
Trying adapt to a lack of space in a hot environment in the middle of the sticks were pack rats rule the west and Rattlesnakes visit me regularly.

Thanks Randolph for the photos. Noticed you had said your model was 1/2VB. Was wonder about what the ‘B’ represented. Looks like BP J style motor configuration. Does the head NOG forward?

Yeah been on eBay exactly 22 years (just check Sept 25, 2000). Back then there were really good deals as people were trying to get rid of things.

Boy that is a big change climate wise Your move to AZ.
 
I’m curious how tall is this machine?

I would like to upgrade my round column mill at some point, however my mill location in basement is under a heating duct so limited vertical space.

Height was one of my concerns looking for a mill since plan to install under a pallet rack. You also need to take into account with cover flipped open and removing the drawbar.

Check out post# 51 which will help with different dimensions.

imagine near everyone is aware of the cloned Mitutoyo 6” calipers, my question is have they also cloned the 8” calipers or are they a safe bet to order on eBay and get a genuine Mitutoyo?

Thanks I missed the details in #51. The good news is that one of these will fit in my space no problem. I'm going to keep an eye open.

Yes, there's no rack or screw. Loosen 4 bolts, tighten one spreader bolt and then it slides forward. Also L/R 90° tilt. The last suffix seems to be the difference between mine and Bob's unit.
Also came with a 5" riser to add to the height of the column. I haven't installed it yet. To the top surface where the motor bolts is approx. 6 feet.

6' to where the motor attaches. The motor is about 10-11" above that...
