With regards to Harbor Freight- I picked up a metal cutting bandsaw there for$179.00. Not the most precise tool I've ever owned, but it's about the sameas the inexpensive Delta (and other brand names) you can pick up locally for much more $$. Now that I've had it for a while, I don't know how I ever did without it.....> Date: Fri, 18 Jun 1999 13:05:58 -0600

Hi all,I have an older style (more like old) 80" Sears bandsaw. Has anyone been ableto figure out how to slow down this perticular band saw so it can cut metal? I have been trying to figure out how to add a "jack shaft" and a pully to gearit down but I can't figure out how to do it with the way the motor is mountedunder the table. So, if anyone else has this saw I'd apreciate suggestions.ThanksChris T.Sacramento, Ca________________________________________________________________________________

Hi:I have a Sears 80" bandsaw too. It dates back to the 80's also. I also havea router varible speed control that I got from Harbor Freight. I got curiousafter your message and I tried it out on my bandsaw. It worked fine, slows thespeed significantly. There is a caveat on the speed control that it is notfor use on AC capacitor start motors.I noticed in a recent Harbor Freight catalog that the speed control special price(half price deal) is $12.95. I use mine occasionally on the router and it performs as it should.Hope this is useful.Lou LarsenP.S. Just finished installing the brake assemblies on my straight axle gear, (21"wheels). used 5" go cart brake drums with external brake bands; mechanical/cable system. Have the bird back on the gear now. ----- Original Message -----

You could try making a variable control. Get a pice of electrical cord with themale end, a steel double outlet box with cover plate, a standard wall plug anda light switch dimmer control. I used that setup to control heat on solderirons.Dick N. ----- Original Message -----

Another alternative would be to install a 3 phase motor with one of the newsolid state variable speed controls.These things will go from near zero RPM to rated speed with the turn of adial and still deliver full power. You would still have to change bladesfor metal but not all metals should be cut at the same speed anyway.Example Aluminum versus 4130Bob B.----- Original Message -----

If the motor drive a belt one can use the motor as the jack shaft with adouble pulley on the motor. I made mine with a 14" diameter out of 3/4"plywood. Then when I want to cut steel, which is infrequent, I put a v-beltbetween this large pulley and a small one on a second motor. Only turn onthe 2nd motor. Don't forget to remove the v-belt when done so you don'tdamage a 2nd motor with extra high speed if your turn on the original motor.I have been doing this on my 20" bandsaw for over 30 years without aproblem.Cy Galley, TC - Chair, Emergency Aircraft Repair, OshkoshEditor, EAA Safety Programscgalley(at)qcbc.org or sportpilot(at)eaa.orgAlways looking for articles for Sport Pilot----- Original Message -----

Subject: Re: Pietenpol-List: BandsawChris T.......I subscribe to a magazine called "The Home Shop Machinist" which is published bi-monthly. The Jan/Feb 2004 issue has an article on convertinga wood-cutting bandsaw to a metal-cutter. The conversion he describes involves the addition of a jackshaft and idler pulley and may be too involved foryour interests, but he has some good data on saw blade speeds. This is kind ofan obscure publication and you might have difficulty finding a copy. If youre really interested, contact me off-net and I'll zerox a copy for you and send itby snail mail.

Exactly! The brush type motor in a drill or "Skill" saw are called "universal" motors and can be run on AC or DC. only voltage dependent. Only reason themodern day ones cant be run on DC is the variable speed trigger is a circuitby itself and can't deal with the DC.I'm sure it wouldn't be hard to find an old style 1/2" drill at a flea market andrun it thru a rheostat, and somehow run it through the existing motorwalt evansNX140DL ----- Original Message -----

I am using a frequency drive on my drill press, motor is a three phase0.75 Kw ( 1Hp) 380/220 volt, cant remember if I got it connected in staror delta will have open it and check, the drive is a single phase inputand three phase 220volt output. Please note that in South Africa we use220volt for domestic use. The drive can also be controlled via avariable resistor for different frequencies (speeds) I usepre-programmed speeds, found that under 15Hz the current is to high. Ialso have one on my three phase compressor programmed to 50Hz. So far noproblems benn about 5 years in use.Norman StapelbergZS-VJA (rebuilding)South Africa-----Original Message-----

Chris,I know you asked about slowing down the bandsaw. I thought I would add a possiblealternative. Use it as is. I have the same bandsaw. I wanted to get startedon cutting out metal fittings. I just used the wood cutting blade that wason it at the time. I was shocked when it worked. I have since cut ALL ofmy metal fittings using the band saw at full speed with either a wood cuttingblade or a metal cutting blade. I look back now and wonder why I wasted timetrying to figure out how to make something to slow it down. The only cautionI give is to make sure the saw is cleaned out after cutting wood and before cuttingmetal. Otherwise the sparks from cutting metal might cause a fire withthe sawdust.Hope this helps someone.Ted ----- Original Message -----
