Open Question

Wisconsin w4 1770

I have a BC935 and after replacing drum bearing it bogs down pretty easily when chipping anything. Have adjusted bed knife , put new knifes and still same problem. Could it have something to do with engine and if so what would be the symptoms ? Any help is much appreciated.

Do video slots pay out as much as reel slots?


They pay based on hold percentages pre-set (but adjustable) chips. In Wisconsin for instance the native casinos are not allowed to choose the hold percentage the state dictates the % with the compact in place. The type of machine has no bearing on outcome. Slot machine broken down to the simplest form are random number generators. Certain combos of #'s trigger different outcomes, there is little to no chance a player can affect the outcome.

How do I change the blades on a vermeer 1600A chipper


Place the chute over the rotor. Remove all the clamp bolts for one blade. This will allow you to remove the old blade and clamp bar. Clean clamp bar and blade slot. Install new blade with clamp bar. You will need a knife gauge for this. Use the knife gauge at each end of the blade. Torque clamp bolts to 280 ft. lbs. After blades are installed it is necessary to adjust the bed knife by loosening the three bed knife bolts. Use the set screws to adjust the bed knife to 1/16 in. above the lower feed plate. Torque the bed knife bolts to 250 ft. lbs. Then use the other two bolts to adjust the lower feed plate to .013 to .016 between the bed knife and the rotor blades. Put the chute back into place and you are good to go.

I tried to replace the front wheel bearings and I can't get the wheel to go back on the spindle. What's the problem??


I take it this is a rear drive car, with normal tapered bearings?

First of all, do you know you got the right size bearings?
Did you try to fit them to the axle?
It is easy to check the outer bearing, since it goes on after you put the wheel on any way.
You need to take the grease seal back out of the inner one, in order to check it.

But you probably are replacing the bearing because the old one went bad. In which case it probably seized up at least once.
This can put score marks on the spindle that need to be removed. Generally one uses a strip of fine abrasive cloth, and basically strops the spindle until the bearing slides on and off easily.

Finally, if this is a drum brake system, it is also possible that you simply did not set the shoe adjustment right, so that the shoes do not interfere with the replacement of the drum.
You want to back off the adjustment all the way.

If you are trying to do this with the wheel on the drum, take it off.
It is hard enough to do without all the extra weight.

Uneaven thickness when planing. how do i adjust


You mean you're getting speed bumps? Do you have the blade setting tools that came with the planer? You need them, it will be hard to do without them. It is a little C shaped jig that rides on the drum over the knife, you have your knife sharpened and set in the drum, snug, not tight,under the knife are adj screws, you run the knife setter around the drum and just scrap the top of the knife, do not pull the knife, just go over it barely scraping it, then snug it up, do not tighten anything yet, move on to the next screw, do the same thing, then the last screw, then go back to the first, still good? second, third, now, tighten them up, the setter doesn't pull the knife, just barely scrapes it, but it does hit it. Now do the other side. Both knives will be set the same, no more speed bumps, or uneven cuts. To move the knife back in, if you brought it out too far, use a block of wood to tap it down, make sure you put the elevation screw down first. Do not answer the fone while doing this. It is serious stuff, when those knives start flying. Hope this helps.

My machine bangs on a full spin.is it the drum bearing?its a hotpointwf340g.how do you replace bearing or fix this problem.


If it bangs it doesn't necessarily mean it is the bearing that is gone. It could just be a imbalance on the load inside. To check if bearings are gone open the door and at the rear of the door seal nearest the inner drum use your fingers to hold down the outer drum, will be at rear edge of seal, now use your other hand at the top pressing the inner drum edge and now press down on outer drum and up on inner drum. If bearings are gone her will be a lot of movement between the two. If no real evident movement then you can feel pretty sure it's not the bearings. Check suspension for signs of wear and check for loose weight block, also check for loose components inside the shell that may be hitting the outer drum. Could also be that the machine is unbalanced if the feet adjusters are not properly adjusted to level the machine correctly.

How do i sharpen cylinder mower blades


I believe you mean to say a 'reel' mower. Normally and old fashoined push (non-engine powered) mower.

Most consumer reel mowers do not need to be sharpened. They do however have a knife bed that occasionally needs to be adjusted. It should have the thickness of a regular piece of notebook paper between the blades and the knife bed. (that is really VERY close) You can buy 'lapping compound' from an automotive parts store, and apply that to the bed knife, and then rotate the blades to provide a precise fit for all blades.

Commercial reel mowers, such as those used on golf course equipment are however sharpened normally once or twice a year. It requireds dismantling, and many courses send their blades to a central location for golf equipment, where they are placed on a computer operated sharpener for precision grinding. This cost several hundreds of dollars just for the grinding.

Changing the cutting blades on a mantis Chip Mate


The Mantis Chip Mate was actually made by a Swiss company called Stoeckler, under the model name Bio-Shredder LGM-600. Neither Mantis nor Stoeckler seem to have service parts or info on these models. Given the blade material the edge did last long and would dull out quickly on hardwood material - best to attack only pencil diameter material or soft material. The manual is of limited use but boiled down you have the following info:

STEP 1 UNPLUG IT! (Seems silly to say but just in case someone of less mechanical inclination reads this.......) Also being made in Europe, all the fasteners are Metric, not SAE/Inch.

The motor/drum assembly must be removed from the chute housing to get to the blades (7 - 5mm allen head bolts holds the drum inside the chute housing). A "T" handle hex wrench a minimum of 6" long will work to access some of the tigher clearance areas. Use a WIDE Large blade screwdriver the help separate the drum halves if they don't come apart too easily. The drum is the motor so it will stay with the smaller plastic housing part - DO NOT force the drum off the small housing part.

A 10mm open end wrench is needed to turn the bolts into the wedge/blade assembly on the drum (ie. turn the bolt head so it screws IN) to loosen the wedge assembly until the blade and wedge can be removed from the drum.

The blade goes back in the wedge blocks so the the bottom of the blade rests against the wedge and not the drum (ie the sharp edge against the wedge not the drum). Make sure the holes in the blade fit over the bumps in the wedge.

You'll next need to remove the counterknife inside the chute house and make sure the edges therer are sharp (you can flip the part around to use any of the 4 edges and bolt it back in or file them sharp and reinstall into the chute housing, BUT LEAVE IT LOOSE.

You need to adjust this counterknife distance from the drum knives. You'll need a 3.5" wide or so piece of shim stock that is 0.3mm thick. Put the drum/knife assembly back in the chute housing and rotate the drum around until one of the drum knives is under the counterknife. Insert the 0.3mm shim stock between the drum knife and counterknife. Push the counterknife down and tighten the 2 bolts that hold it in the chute. Pull the shim out, rotate the drum to the other drum knife and check for clearance to the counterknife. As long as it rotates by and does not hit you should be ok, but if they are really close, re-adjust the counterknife for 0.3mm clearance to the highest knife. Make sure the gap does not exceed 0.5mm or the unit will not chip/shred properly.

Put everything back together and make sure the bolts are tight!

Should be good to go. Given the blades don't seem to be of any particulary great hardness, I would feed material slow and easy and avoid any hardwood material over 1/2" in diameter. If you need new blades you need to search around to see what can be ground down to fit. Find yourself a person who really knows how to sharpen blades and they should be able to cut something down to fit.

Good luck.
