And if the motor is not brushed? Will it work but burn up the motor, or simply not work?We use to call those a variac it will work if you have a brushed motor.. Ray
Yes it will burn up a non ac brushed motor windings.. RayAnd if the motor is not brushed? Will it work but burn up the motor, or simply not work?
I have the exact same issue facing me. I have an old Craftsman saw that looks about like this Power King that I want to do the same thing with. Thank you for this thread!
At any welding supply you can get any width metal cutting blade you want I bought 1/4 and 1/2 for mine for $10 a piece. The tires or bandsaw wheels are no different on the wood or metal ones I have seen combo saws that use the same wheels and guides. I have used bandsaws in machine shops that run all day long with no coolant and in a home shop is not needed. If you dont tell the bandsaw it was meant for wood it will never know!!!!That's a handsome looking machine you have there! However, wood cutting bandsaws sometimes have issues OTHER than just being way too fast for metal cutting.
The blade is typically pretty narrow, making it easy to cut circles and such, which is what they're designed to do. Metal cutting bandsaws typically have a heavier blade, at least half an inch front to back, and more teeth per inch. Verify that a metal cutting blade is available before putting a lot of work and money is that saw.
Another issue "may" be of concern. Check both wheels to see if they will track OK with the heavy big metal cutting blade, AND that the coolant that you'll want to use to prolong blade life won't affect the bottom wheel. Probably not an issue, but wood saws don't expect to be immersed in liquid while operating.
If everything looks good at that point, a jackshaft arrangement should work great. The support stand you have should make it a snap to gear it down.
Thanks, I know that's why they were coming off.. the 70 year old tires on it were down right ugly. See my post above.If those are 14 inch wheels Grizzly sells the tires for them that is probably why the blade kept coming off great find it should work well for you.. Ray
Thanks. I will probably center the saw on the stand to make it as narrow as possible. The stand must have been some kind of kit that was available back then.. It is assembled with screws, nuts and these funky clamps:I agree- beautiful find!
I used a cheap lathe countershaft I found on eBay, and hung it underneath the bandsaw to slow it down.
The stand is perfect- easy mounting motor, jack shaft, countershaft underneath to slow it down.
Don't regret it a minute- just utilize the opposite side of the stand for something else-
Maybe even turn the bandsaws to fit sideways, making more room to use on the other side?
What a beauty!
As mentioned in an eariler post, I already have new tires coming. Thanks for the blade info.. I like the idea of cutting them to size myself. I only plan to cut 1/4 mild steel and aluminum.Go on ebay they have the rubber repacement wheels. Use a treadmill motor and the smallest pulley you can find to reduce the speed, they work great , i have done several.As far as the blades go buy doaal blade material and silver solder your own to any lg. you want, using a simple jig. I like 1/4' WIDTH the best in either a 308-601 or a 309-047
Thanks for that explaination.For reference, the reason that you can't regulate the speed of an induction motor by just turning down the voltage (that's what a variac does) is how the motor controls the current draw under normal conditions. A motor is also a generator. When a motor starts turning, it starts generating a voltage (counter EMF or CEMF) that opposes the voltage that's making it turn (EMF) . When the CEMF balances the EMF, the speed and current stabilize.
If you put more load on the motor, the speed is reduced and the CEMF is reduced. Without the counter effect, the current increases, adding enough torque to the motor to hold the new, lower speed and set a new balance. If too much load is added, the rotor will stall and maximum current starts to flow. If the control system (or operator) doesn't shut it down, the high current will generate high heat in the windings, burning out the motor. Running at reduced speed and high current, even though still turning, will over-heat the motor and eventually damage it.
VFDs control speed by changing the frequency and adjusting voltage and current for optimum performance. This is quite easy to do on a 3-phase motor, not so easy on single-phase. I'm using a jack-shaft on my bandsaw conversion. Much easier and cheaper.
I laid it side ways in my truck and then shifted it 90 degrees so I could close the topper and the sudden weight on the table broke the trunnions. Poorly made. The Power King is all solid steel! Loaded it the same way and nothing broke.Heck yeah, it was worth $10.00. The light is nice.
Bet you moved the Band saw by the table when you broke the trunnions.
Looks like a Delta clone. That motor is about $200.00 new.
I don't know about that.. I have seen some nice lathes for sale up north where you're at.. I rarely see any for sale down here. Rarely see any American made machine stuff at all.. I was just lucky and also the dude was a nice guy.Heck yeah! As mr breeze said... Man, I gotta move to your town- no good deals like that by me! Not even on Craigslist!
Since you are asking opinions, I would leave as much of the original paint as possible- can't beat that experience these machines have been through in -100 years?! Fantastic.
I thought about making a work table out of it, but If you were in South Florida, I would give it to you.I like the original finish on the saw myself. I also like the original stand the saw was setting on though it is a bit clumsier I suppose. I don't suppose you want to sell your old original stand do you?????
Actually, it is just real traditional. My vert bandsaw sets on a stand that could be it's twin. I have a 4" wood jointer on another stand that looks just like it as well. Those stands were the norm back when those machines were made.I thought about making a work table out of it, but If you were in South Florida, I would give it to you.
Nice that some one apperciates it, but to be honest with you, I don't want to go through the hassel of disassembling it and shipping it.. I know this sounds cold, but that's the way it is.. I would rather use it for something before going through that.
Now If you knew a forum member here who could pick it up for you..)
Probably cost 1.98 back in the day.. It really isn't heavy duty, but it is structured and unique.. I like the way the legs curve..
