Topic tags/keywords: bandsaw

Just checked craiglist and the local public school is selling a number of tools
in particular a Rockwell/Delta 24” band saw, model # 28-350 at $500.
They claim ” It is in good working condition. ” I have not seen it, but will go see it today. It is 3 phase 220 volt. I’ve been considering building a bandsaw for re-sawing.
My questions:
  1. Is this a good deal? My plan was to use it for re-sawing. I have an old 12” craftsman for cutting patterns etc.
  2. Would I be better off building a bandsaw for re-sawing? This was my summer plan.
  3. I have one 220 volt circuit that I use for my Jet vortex dust collector. (I don’t know if its 3 phase single phase.) Can I run both the dust collector and the band saw on this circuit or should I add another circuit? I have a single bay garage shop with an apartment above and had the 220 volt circuit put in
    last year.

1. Maybe, depending on condition. That’s a good 20” (not 24”) saw. I had one.
2. No.
3. Yes and no. You need to add a phase converter for the band saw. It
is a minor complication that will cost between $100 and $300 to solve.
On mine I switched out the 3 phase motor and installed a single
phase motor. I had to get the sheave (pulley) bored out to
fit the replacement motor shaft.

Check if the brake works, check the tires (minor cracking is no big deal),
look for repaired parts, etc.

Loren Thanks for the quick response.

BTW Looking around the internet I can only find that the 28-350 is a 20” bandsaw. I wonder if the 24” is wishful advertising. I’ll check it out today.

Mine would shimmy as it powered down. If it was screwed to
the floor it probably wouldn’t have. I don’t know if the shimmy
is typical. It didn’t affect cuts negatively.

I liked the saw a lot.

I’d have to put in on wheels … I think … but maybe I can reorganize. Not sure what to do with two bandsaws, but I ‘ll probably keep a 1/8 blade on the smaller and 1/2 to 1 inch blade on the larger. I’m not sure how I’ll get it into the shop. I suppose its very heavy and I’ll need help. Also it is -11 today and there is 4 feet of snow.

Do know the blade length?

My concern would be how it was treated by students and maintained by the teachers.

My guess would be it wasn’t used a great deal as compared to a commercial shop. I believe that school shops are generally considered lightly used tools. Of course we never know but when buying used tools….you never know. If it were abused too much and not maintained by the instructors then it would have gone by the way many years ago.

The saw is probably in very good condition. Schools don’t let kids use machinery unsupervised and any shop teacher worth his salt would keep it safe from abuse. The one car garage and having one 220 line are major issues. You’d need a phase converter so the price just went up considerably as I doubt the residential setup in your home is three phase. Would I like to have it myself? Yeah. Would it cost me an arm and a leg for a phase converter or new motor? Unfortunately the answer is yes on this one too.

I just saw it. It is in excellent condition. It runs well. Tire’s look good, motor looks good, brake works. I could not find any thing wrong with it. The shop teacher of 29 years has never had to replace or repair any part of it. The school shop has 4 other band saws and so this big intimidating band saw is rarely used. It will come with 3 additional saw blades varying from 3/8 to 1 inch. It comes with a fence and rails which have been removed, but can easily be re-installed. I looked around my shop and I can make room for it although it has a 48” by 30” foot print and will become the largest machine in my shop. The only question is how much a 3 phase converter will run me. There used to be an electric hot water tank for the above garage apartment so I have room for a second 220 circuit. A second circuit is no biggie. The only issue is getting a phase converter. Anybody have suggestions for phase converters?.

Looks good, but frankly putting a riser kit on a 14” bandsaw is just as good unless you plan to open up a millwork. I’d get the price down with some cash and sell it for a profit.

I’ll suggest a static phase converter which you can get for
less than $100 on ebay. You’ll lose 1/3 of the motor power
but even then the motor will probably be adequate for
most tasks you’ll use the saw for.

You can build a rotary phase converter which will give
you full power, but considering your space I doubt you’ll
be acquiring more 3 phase equipment.

Another solution is a variable frequency drive which you
can now get for a little more than $100. They can
do phase conversion and other tricks like speed
control but they are high tech and there are durability
concerns when they are used for phase conversion.

I’d buy it. The old stock fence/rail sets on those are
sought after I think.

I think I could just replace the motor with a single phase motor and not fool with a phase converter. I am not sure I’d save any money on this. It seems to me from what I read in the manual I could replace the motor with a single phase 1.5-hp 220v motor.

The manual says:

Under average conditions a 1 hp motor will furnish ample power for this machine. When considerable heavy cutting is to be done, a 1.5 hp motor will be more effective. Use a constant speed motor. is 1725 rpm, which will run the blade at 4500 feet per minute. With 50-cycle current a 1425 rpm motor should be used, making the blade speed 3800 feet per minute. These speeds, being suitable for most wood cutting operations, are obtained with the 3.5-inch motor pulley and 7-inch drive pulley furnished as standard equipment. No other pulleys for this 2-belt drive are available. When some other drive ratio is desired, to change blade speed or accommodate a different motor, the customer should have a new pulley machined locally according to the standard belt groove dimensions. The standard motor pulley CBS-140-S has a 3/4-inch bore and 3/16-inch keyway. It will fit any of the Delta motors recommended for this machine. Consult your Delta dealer for the correct motor to meet your needs.

The No. 49-314 switch box assembly may be used with single phase and DC motors. Convenient mounting of the “on-off” switch is provided on the band saw column to the left of the table, as shown in Fig 1. This switch assembly includes all parts needed for a permanent and safe connection and permits the machine to be operated from any convenient power outlet. For three-phase motors use a manual or magnetic starter and the 3-wire armored cable No. 49-315. Starters of various voltages are listed in the catalog. The 3-phase manual starter No. 1320 may also be used for single phase and DC motors, when overload protection is desired.

That’s a nice saw, but considering you have to convert it to single phase some how AND move it yourself or hire someone I would just go get a brand new $750 saw like a Shopfox or whatever brand you like that comes with a warranty. $500 is not really a bargain. I love old iron, but I think it’s just too much.

I have a 20” Powermatic that is almost 50 yrs. old that the students use daily. Bandsaws hold up well from student use. The only thing that has been replaced was the motor and tires. Buy it, ‘should last you a lifetime. I see you at a Technical school, I am sure you can find help on any changes needed to the bandsaw. You could get lucky and they have a motor that would meet you needs laying around.
