20 degrees? I'd definitely have a lift lined up, unless you have a small army on hand.

Now 4.2 degrees, that's only about a 7 inch rise in 8 feet. Totally do-able with a pallet jack and a buddy.


As far as the base goes like others have said, stay away from wood. And I'd also wait until delivery before making a base, unless o/c the idea of fabbing up another doesn't scare you. I'll be making something similar to these after mine (knock on wood :lol: ) arrives:

it looked like 20 degrees from the street but I used an igage angle measure and based the zero degree from the driveway and checked it about every 3 feet so yeah it looks like 4.2 all the way up. That does give me a bit more confidence to run this up with my friend since a rigger seemed a bit more than necessary for 20 ft.....

So the two machines you two posted look about the same height from the floor up to the bed. Being 6'1" I'm really gonna want a stand right?

That looks like a good idea on the stand with the casters. Perhaps we'll see if my welding can hold 1 ton :D

I was just gonna buy a mini mill but realized quick it wouldn't hold up and I'd be severely limited. Plus the girl came in and saw what I was looking at and said I deserve to get whatever I want. I'm about to make over 70k profit on selling my house and like any man should, I'm buying a really expensive tool she just helped justify spending more ;)

I'm 6'3" and from what I remember a full size BP sitting on the floor (doing mostly low profile, in the vise work) was fine for me, however that might be a different story today now that I'm older and blinder. The 1st shot is of a 2/3 - 3/4 size machine similar to what I'll be getting and I anticipate the need to lift it in the neighborhood of 5 to 8 inches. Going to give it a couple runs after it gets here while still on the pallet before committing to fabbing a base for it. It's really all relative to whatever kind of work you'll mostly be doing. I tend to base height requirements on where my eyes will be focusing, you know where you'd want a higher machine for doing say plate work that's toe clamped directly to the table vs. working on something like an engine block or the like.

Sounds like a real keeper you've got there!

Any holding up a ton is nothing, so long as the design supports it.

I've seen plenty of video of the BP and it does look like that was designed to stand at all day long like a good classic 1940s worker should be doin. These new ones all look like they'd really benefit from stands :\

I do plan on only really doing low, flat work but I said I'd only really be doing Al with TIG and I've got my fair share of steel and SS now with a Ti fix ready to go. I'm getting this for the potential and to remove as many limitations without taking up a 10'x10' space, weighing over 1 ton, and not costing 15 grand just for the machine. So the imagination and laziness should be my only limitations :)

Looking at casters, it looks like a 900 lbs load rating is about the best minimum and that looks to be about 7" mount height with 6" wheels. Looks like I have my base height to consider for a stand now. I know those crappy metal tab brakes are horrible so after a bunch of searching I found these look like the best options for swivel casters and brakes which it shouldn't be hard to find the ridgid or non-braking matching set for these. Figured I'd post in case it helps you, anyone else, or if my browser history dies ;)

I looked at my manual for my 2300 lb mill and for securing to the concrete they recommend using a 5/16" minimum sized anchor. :shock: So a 3/8" anchor would more than likely work but I would go with 1/2" if I were to anchor mine. But it hasn't moved in years and I don't move it when cleaning the shop. I also have a 2400 Sq ft shop so your mileage may vary. :D

Thanks for that point about the anchor size :) Yeah I def don't have a shop that large; one day maybe but I'm pleased with what I have :)

Have you been doing fine precision work or just using the mill for what a mill is good for? I'm guessing if you had a concern or noticed problems you would have bolted it down by now...

Precision work is not a problem with the mill even not bolted down. It's level and weighs over a ton so it doesn't matter. Proper use of the mill is what matters. Leave the quill up and use the quill lock, lock the table and knee or whatever axis is not going to be traveling. Use good tooling and set the speeds and feeds properly etc. Make sure you tram the head so it is square with the table and same goes for the vise on the table. Learn about direction of travel and what difference it makes between conventional and climb milling. Lots to learn but lots of fun too. Tooling will cost as much as the mill....eventually. :lol:

I don't know if you're looking for a review on the quality of their stuff but for what it's worth my boss has the funds to buy whatever he wants for his machine shop and he bought a Grizzly mill and lathe. They're very nice and I'm assuming he likes them pretty good. I'd feel good about getting their stuff. I've been looking at one of their smaller bandsaws myself.

There is NO good reason to anchor a machine tool of this order to the floor,
unless you live in an earthquake zone.
Check on renting a fork- lift even a small one will lift 2000 pounds easy.
You may also be able to rent what are called "machine skates" basically 4 wheeled
caster like things that you can sit under each corner and use a pinch bar to move the machine.
Last mill I moved we used old engine push rods as rollers and you could move the thing VERY easy.
IF you want feet under it something like this is good

They can be expensive, but most folks I know use hockey pucks and make their own

that looks to be very nice machine, and I am jealous, as a knee mill is the thing most lacking in my shop.
You will find 1000's of uses for it and I really like that it has the horizontal arbor drive as well.
Grizzly tools seem decent for the most part. I would expect you will spend several days cleaning, lubing, adjusting
and fine tuning as you should with any new machine.
Congrats!
