Hello all - i usually spend my time over in the south bend wing but i'm considering a Benchmaster MV-1 purchase and have a few questions. i-ve read a lot of threads here and elsewhere and fo.ks seem to fall into two camps - a benchmaster is well bilt'but too small and a benchmaster is an ideal machine for'the typical home shop needs. assuming i have accepted the size limitations - what should I be looking at in terms of machine condition, tooling that is necesary or specific to the machine and anything else I may be missing. logistically what is the size and weight -i'm wondering if it would fit in a small SUV (RAV 4). Finally'what is the relative value'ofthese machines assuming good condition and excluding any tooling.

thanksfor yourhelpand thoughts
Rick

I would buy a Benchmaster in a heartbeat, and replace my minimill with it.
You should be able to get it in the Rav4 with no problem.
200 lbs. Put down a piece of heavy plywood to spread the weight.

thanks guys - i'm going to see it up front amd personal this afternoon. I'm pretty sure it is a vertical which from'what i have read leaves a pretty small working envelope. the small working envelope, lack of power feeds and lack of a quill seem to be the most often mentioned negatives. I believe the vertical will work with steel as well as aluminum/brass/bronze. The asking price is high - $1000 - which starts to approach a used bridgeport - on a very good and lucky day.

Other than E-Bay and craigslist (which is hit or miss in my area) is there another place to find Benchmasters for sale?

Thanks

i went and looked today the machine seems in pretty good shape - everything seems tight with very little'backlash in the table movements. Not much tooling goes with it - a vise, a couple'of collets, lots of end mills and some misc stuff (some parallels, 90° angle plates, surface gage, etc). after some comversation we ended up at $700. I didn't commit but seller agreed to giveme a few days to think about it.

Well I picked up the new to me bench master today - you can say a lot of things about them but you can't accuse them of being lightweight :). Some pictures below - the machine is still resting peacefully on its side until I wire wheel the stand and get some paint on it. I don't want to move this any more than I have to.

the first few pictures are of the machine and stand
Under the base - I was expecting to see some rust here but nothing

The machine itself (serial number 8674) - the discoloration is more grime and dirt than surface rust.
Mill.jpg

and the stand
Stand.jpg

finally the motor - 1/2 hp craftsman 1750 single phase
Motor.jpg

The next pictures are the "accessories" that came along for the ride
This was a box full of stuff (Vee blocks, parallels, a sine plate, various clamps, surface gages, some reamers and a bunch of other stuff that I'm not yet sure about). Unfortunately there is some corrosion - some pretty serious - but I'll see what I can do to clean it up. I believe a lot of this was user made.

next was a user made shelf with a drawer - more stuff in the drawers - reamers, more clamps, drill chuck, etc.
StuffinDrawer.jpg

Finally was a box of end mils - 173 to be exact. I'm betting there is a lot of junk in there but I also think there is a good supply of useable end mills

I'm feeling like I did OK with this deal.

Any thoughts about putting a mobile base under the stand - would that be detrimental to the machine operation?

Thanks
Rick

All my mills have mobil bases under them.

That certainly came well tooled.
You will probably want a real milling vise early on.
Also a holdown clamping kit.
Nice score! :man:

AR1911 - ok a couple of'questions
first the mobile base - others have suggested that leveling a mill is as critical as a lathe and a mobile base cojnteracts the leveling - any thoughts?

second - what is a real milling vise - are you referring to the lower profile vises I habe seen? any suggestions or links to one that would be the appropriate soze for this mill? is the vise that is on there more'of a drill press vise?

Finally - not sure what youmean by hold'down clamps - can you tell memore about that?

as you'can tell this is a'whole'new'experience forme

thanks
Rick

I know a lot of guys have mobile bases under their machines, but unless you need the ability to move things out of the way, like to still get the car in, it's best to have the machines set as stable as possible. Not necessarily anchored, but on leveling, anti-vibration pads. Just my preference.

I think the other guys have covered this. The primary benefit of a level table is to make setups easier. You can use a level or a digital protractor to set angles, knowing that the table is at 0. Does not affect accuracy.

second - what is a real milling vise - are you referring to the lower profile vises I habe seen? any suggestions or links to one that would be the appropriate soze for this mill? is the vise that is on there more'of a drill press vise?
What you have is a drill press vise. I have one just like it on my drill press. The movable jaw is held down with something less than precision. On a real milling vise the jaw moves on ground ways much like a lathe.
Look for a 4" angle-lock vise. they are very common. http://www.ebay.com/itm/NEW-4-ANGLE...7?pt=BI_Tool_Work_Holding&hash=item20c7eb9921

Finally - not sure what you mean by hold'down clamps - can you tell me more about that?
Shawn has already posted a picture. As he said, be sure the tee-nuts fit your slots, and the studs fit in the slots too.

Thanks for all the info folks - it is'very helpful. My first step is to get the table cleaned up and painted. I'm going to try the leveling casters on it (I currently have a set of those on a wood lathe that I can use to protype). The next step will be to get the machine cleaned up a bit and set up/ leveled on the table. No plans at this point of a complete disassembly but time will tell after some use. The one thing I didn't get a lot of was collets so'that'and a vice'will be on the top of the purchase list. I'm also going to take the advice about joining the yahoo group

I thought I'd post a few pictures of the mill standing up on its newly painted bench. After seeing it upright and playing with it a bit I've decided I'm going to tesar it down for a good cleaning and painting. More to come on that

You got a good deal on the mill and to get all that tooling. I like my Bencmaster it was a production machine and I put a 1/2 inch 10 tpi acme threaded rod for the lead screw style. I got mine for $350, no tooling. I bought a 3" mill vicefor about $90.

Re: Cleanup. I buy a gallon of WD40 at Home depot for $15, and use a trigger spray bottle. That, a couple of stiff brushes and shop rags will have that whole thing shining like a new dime.

For rust removal, but a gallon of Evaporust, pour it in a plactic container, and pile all that rusted tooling into it. The more the merrier, but don't let any of it stick out of the liquid.
Next day pour off the liquid, remove the tools and wipe down. They will be rust free with a thin protective coating.

Save the liquid for the next batch. Won't hurt paint, plastic etc. You can let it sit for days or weeks if you need to, but cover the container.
Good stuff.

I bought a clamping set only to find the t-nuts were just slightly to big to fit the table slots, I'm using some carriage bolts that I ground the heads on as a temporary solution until the metric clamping set arrives. The size of the t slots on the Benchmaster table doesn't seem to be very common?

Shawn,

So what size clamping kit fits the benchmaster?
Thanks.

You have a mill. Why didn't you just cut the tee-nuts to fit?

Thanks Shawn and AR1911. Will wait to see what you finally purchased.

Rick B that was a great buy you got for your milling machine and the dream set of tooling.
Congratulation.
