Tropical storm Michael is about gone from Raleigh area. the 'eye' passed about 5 miles west of the house about 5pm. Other than a few limbs and scary wind, no damage to my house. Hope everyone made it thru ok.

my experience has been 25% of rated speed and motor does not seem to mind. it will depend on the actual motor/vfd combination.

buy a motor/vfd combo and get going. save pennies and get: a 3" drive wheel an 800 rpm motor a 6" drive wheel the direct drive grinders i have or have used changing drive wheel will take about 5 minutes. changing the motor will take about 10 minutes. so to 'hog' you use 6" wheel with 3600 rpm...

everyone seems to concentrate on highest available belt speed. while this is important, especially when using belts of 100 grit and coarser, when using finer belts and finishing, I think speed needs to be low. how long does a 220 belt last at 4000 sfpm? how long will that belt last at 500 sfpm?

to find belt speed: 3.14 x diameter, then divide by 12. take result and multiply by rpm. you end up with feet per minute. 3.14 x 4"=12.56 12.56/12 = 1.05 1.05 x 1800 = 1884 fpm this would be your belt speed at 100% or 60 Hz. 3.14 x 6 = 18.84 18.84/12 = 1.57 1.57 x 1800 = 2826 fpm

i would look at total weight and see if you are 2 ounces or less. with something that light, balance is not an issue

one vfd will power one motor at a time. i have mine wired so if i want to change from belt grinder to disc grinder, turn off vfd, then swap plugs.

I would get it. as said, you will need a 240 ac outlet in your shop to plug into.

I would either buy a furnace or spend 1/2 on little stuff and make the other 1/2 my operating budget for the rest of the year. by little stuff i mean good quality drill bits and saw blades, improved shop lighting and ventilation, shop vac that sort of stuff. you need a high temperature furnace...

we have a choices. a knife that is high hardness, ultra thin grind, ultra thin edge which needs warnings like shun and others have on website, soft fruit and veg, boneless protein. if knife is to be to butcher bone-in meat, not a thin a grind, thicker edge, thicker spine, steel not as hard...

flex is geometry not hardness. geometry controls flex and geometry cuts. what i described would be high performance cutter/slicer. i would not see any issues unless you try to baton it. personally, i use diagonal cutting pliers or a box cutter for zip ties.

bottom drawing, do it in 3/32" or 1/16", get rid of bolster, flat grind, Rc 62-63 minimum, either O1 or 52100, finish bevel at 10* a side.

I think so. being an old sailor, I like to add KIS(keep it simple). The more steps you add to HT, the more chances to make a mistake. The more you deviate from "Industrial standard HT", the more chances to make a mistake. As Kevin said above, to avoid a bent or broken blade, don't use it for...

I am currently using a Leeson speedmaster for my grinder. It has dedicated push buttons for on/off, start/stop, speed increase and speed decrease. I have the stuff to do remote switches, but when standing the VFD is within easy reach so i just use the factory buttons.

yes an a/c filter should be ok. i also vacuum mine whenever I vacuum around the grinder, say once a week or so.

Teco, leeson, fuji, siemens, AB, .... are industrial grade VFDs, designed to run 24/7 for years before replacement. They are programmable with a keyboard. You can shop and find them for less than KB. My grinder VFD is located above, to the left and behind the grinder, so it sees very little...

nothing for chinese, but these folks have good selection and excellent service https://dealerselectric.com/variable-frequency-drive-motor-control.asp next motor to look for Boss would be an 800 rpm, with a 3" drive wheel, your sfpm at 50% is less than 400

do you have any electrical repair experience? if no, buy a KBAC and a Baldor motor, find someone to make and install the wiring. if yes, get a TECO or Marathon or Fuji or Hitachi. get a motor, baldor, leeson, us motors, marathon, ......... make sure you shop is wired with 240 vac which you...

either check with an attorney or see if there is a small business group at local colleges that may help. email this gentleman, he may have answers also http://cutbrooklyn.com/ he sells online and from his shop.

which boelube? amazon carries about 6 or 7 different boelube machining lube. for drilling, i keep drill bits sharp, speed low, and go gentle on the feed. for drilling you need cool, so most any oil will work. I have used ice water in a pinch. cobalt HS steel, M35 or M42 seems to make a...
