The shaft in my drill press wiggles back and forth enough that it doesn't drill true i.e. at 90 degrees to the workpiece. How to fix?

Try and get some CRC into the top where the hook joins the shaft. You need to be rocking it back & forth to try and get movement. Gradually the movement will increase if your strong men are strong enough and have stamina as well. Once you get it off clean up the shaft with a wire brush. Clean out the hole in the dough hook with the proper size drill, you don't want to make the hole bigger, just cleaner. It will be a build up of flour in there, it packs hard and shrinks the hole, almost unbelievable but true.

some saws don't set up when select 90 degrees , unplug saw then take a small square like a combo square , place it against the side of the blade and flat down on the bed of the saw adjust to the square regardless what the setting shows take a fine black marker and put a small dot on the indicator that is on the saw then you know where your true 90 is and always use the dot . should do it even some expensive saws are not perfect i always check the all before cutting if havent used saw before

I'm assuming you mean a spade drill bit?

For best results, try clamping a block of hardwood to the back side of the stock before drilling. When the bit approaches the end of the cut, it will be far less likely to blow through with another piece of wood to drill. However, if the stock placed on the back side is softer than the workpiece, or if it is not securely clamped to the workpiece, tear out can still occur.

To use a spade drill bit, mark the center point of the hole to be drilled on the wood, and install the shank of the bit into the drill. Align the point of the pilot tip of the spade drill bit with the mark on the wood, and adjust the angle of the handheld drill so that the shank of the bit is square to the surface of the wood. (Of course, if you're using a drill press, the bit's angle should already be square to the surface of the wood, unless your drill table is not square to the motor).

Depress the trigger of your drill slightly to engage the motor and turn the bit slowly. Hold the drill as still as possible so that the pilot point stays aligned with the mark on the wood. Because pilot tips can often "walk" away from the intended center point of the hole, some woodworkers will pre-drill the pilot hole using a small-diameter twist drill bit that is less likely to walk, and then proceed with the spade drill bit's pilot tip into the pre-drilled pilot hole.

Once the pilot tip is in place and engaged with the wood, increase the speed and proceed to drill the large diameter hole with the spade drill bit. Continue drilling until you reach the opposite side of the wood and the bit pokes out through the completed hole. Slow the speed of the motor, and pull the drill bit out of the completed hole.

If it dosen't lift at all wiggle the large black gear bakand forth a few times they do get tooth for tooth.

Looks like it was made in China, according to results below:

Put a few inches of soapy water (enough to cover the padde and post) and let it soak for a couple of days. Pour it out and holding the paddle and the little impeller on the bottom of the pan start wiggling the paddle back and forth and pull, wiggle, pull, etc,...it should work lose if not go to you tube and type in "how to remove a stuck bread machine paddle" only if wiggling doesn't work...

Hi and welcome to FixYa, I am Kelly

Press in hard.. rotate it 90 degrees Counter clockwise and wiggle / pull it out. When you re-install a new filter align the filter with the internal locking tabs and press in hard and rotate 90 degrees clockwise.

Some times the filter can br really fussy to remove you just have to keep wiggling and pulling to get it out of the recepticle once you have rotated it 90 Deg CCW.

Thanks for choosing FixYa,

You need to undo the allen key in the centre - ps the spring will NOT LET GO so don't stress as it is pressed together

I just picked up an officejet 7410 off craig's list for free because it a had a carriage jam error. I followed all the online instructions to fix it and nothing worked. I tore the printer down to the guts and found a black plastic gear that had a cracked shoulder. This gear is pressed onto a metal shaft which is splined. The splines are to keep the gear from spinning on the shaft. The crack in the shoulder of the gear was allowing it to spin on the shaft which it was not supposed to. I'm assuming the gear cracked due to a paper jam. I fixed this by drilling a 1/16th diameter hole through the shoulder of the gear and the shaft while the gear was installed on the shaft. Then I installed a roll pin(or tension pin) into the drilled hole, thus keeping the gear from spinning on the shaft. Now it works great. One of the pics has a yellow mark where the crack is, with the pin installed 90 degrees to the crack. This requires a little skill, but I hope it helps.

No matter your model Roomba, this occurs when Roomba has gone "crazy." Its brain is no longer working properly and you can usually tell this when you've cleaned the dickens out of it a few times and the behavior is still the same. There's only one possible user fix and that is to take out the battery, hold down the power button for 20-30 seconds then reinsert the battery.

If that doesn't do the trick, IRobot might send you something called an Ozmo which you put in the data port to rewrite Roomba's brain. Unfortunately this requires it to be under warranty unless you get lucky. Good luck, all!
