You might need to buy a kit that lets you drill out the top head and use the kit to back out the screw. These are available at most hardware store.

The bottom thread is real loopy. I have adjusted the top tension and it helps a bit but still to loose

Remove all the thread from your machine. Install a brand new needle. Raise the presser foot and re-thread the upper thread, making sure you are following the correct threading sequence. Confirm that the bobbin thread is threaded through the bobbincase properly. Now, perform another test stitch. Is the bobbin thread still looping?

If you have already tightened the upper thread tension and the bobbin tension is still too loose, then you may need to tighten the bobbin tension. First, mark with a permanent marker where the slash of the screw head meets the bobbin case. This will mark where the screw was originally set before you begin making adjustments and allows you to return the screw to that position should you need to.

Set the upper tension to the halfway point between the high & low number. This is what would normally be the standard.

Then gently turn the bobbin tension screw to the right 1/8th of a turn at a time. Then test. Keep adjusting until the bobbin thread tension is correct. The tensions are correct when the upper thread and the bobbin thread meet in the middle of the fabric.

The blade on my new skil 3310 won't raise. It came preassembled & has never been used, but the elevation wheel feels locked. I can adjust the angle, but turning the knob doesn't raise/lower blade.

Just as a question and I am not being smart you know that the wheel to raise the blade work counter clockwise.
The other thing you need to check is in your manual here is the part how to adjust the blade for raisin/lowering.
After five hours of operation, the blade elevation/tilting mechanism should be checked for looseness, binding, or other abnormalities. Disconnect the saw from the power source, turn the saw upside down and pull up and down on the motor unit. Observe any movement in the motor mounting mechanism. Looseness or play in the blade raising screw 1 should be adjusted as follows (Fig. 55): 1. Loosen nut 2. 2. Adjust the nut 3 until it is finger-tight against the bracket 4, then back off the nut 3 1/6 turn. 3. Tighten nut 2. The maximum allowable play of the screw rod 1 is 5/32" (4 m). Place a small amount of dry lubricant (such as graphite or silicon) on the screw rod 1 at the thrust washer 5. Do not oil the threads of screw rod 1. The screw rod 1 must be kept clean and free of sawdust, gum, pitch, and other contaminant's for smooth operation. NOTE: If excessive looseness is observed in any other part of the blade elevation mechanism or tilting mechanism, take the complete unit to an authorized service center.

How do I calibrate elevation grade for treadmill?

Hey there, sorry to hear you're having an issue with your elevation motor. I would be happy to help you solve the problem.
Since you already installed your motor you can go straight into diagnostic mode.

To get into Diagnostic Mode on your L8
Make sure to turn off your treadmill.

-ET's - Press Menu and Start at the same time
-CT's - Press Manual (or Display^) and Start at the same time
-All other L SERIES mills - Press Display (or display and Start at the same time

-*CT's that were manufactured after 09/2003 - Press Display and start at the same time.

Few things you want to do, if you haven't already.

A. Align the motor with the clevis mount and install the motor mounting pin.

B. Insert hitch pin.

C. Reconnect the elevation harness to the lower board

D. Set the lowest limit switch by holding the UP elevation button for 5 seconds. Then press and hold the DN elevation button one more time to make sure you only hear a click.

E. For L7/L8 machines; Thread the elevation nut to where its flush with the threads on the "worm' shaft.

F. Mount the elevation nut to the leg assembly by lining up the holes on the leg assembly. You may have to move the leg assembly so that the holes on the elevation nut line up. Then slide the two elevation pins through the elevation assembly and into the elevation nut. then secure the pins with the 2 set screws.

To calibrate your potentiometer you can try to adjust while it is installed but for best results you must calibrate it before its in your motor housing.

G. Calibrate the elevation potentiometer and to do so you must;
1st: Visually confirm treadmill is leveled. (0% grade)
2nd: Adjust the settings as follows;
All L SERIES millls should read 0.0
3rd: If the setting is incorrect, follow these steps.
Step 1: Turn the post of the potentiometer all the way
Step 2: SLOWLY turn the potentiometer COUNTER
CLOCKWISE until the setting is correct.

H. Carefully install potentiometer into the motor housing
*NOTE: The setting may vary when inserting the potentiometer
into the motor. As long as the change is minimal, fine
adjustment can be achieved by rotating the meter
while inside the elevation motor.

I. Press OFF to turn treadmill off. Then restart the machine in manual mode to TEST elevation after resetting your potentiometer. As long as the change is minimal, fine adjustment can be achieved by rotating the potentiometer while inside the elevation motor.

For more Diagnostic features and possibly further detail, I will be attaching a Link to your machines service manual. I hope this helps, always hear to help. SportSmith.

How do I adjust the bobbin tension on a mademoiselle 300 sewing machine

Take out your bobbin case Hold it in front of you until you can see the little screw head
Mark down on a piece of paper at what o'clock the screw head is sitting ie look at the screw head as a clock face and see where the time is!!
Then left turn is to loosen the bobbin tension right tun is to tighten the tension.
ONLY move the screw head about quarter turn each time, mark where on the clock you have moved it to
Put back in machine and sew, check stitches Take out again and follow above instructions do again. Most times it only takes a couple of tries to get it right.
. The stitches should be even on the top and on the bottom. Sometimes if you are using a thicker thread in the bobbin it can be tricky These instructions are the same for what ever machine you are using. Sometimes in your instruction book there are how to's on setting the bobbin tension. I hope that this can help you Dot

I cannot move the adjustment knobs on the windage and elevation of the scope

Some time the screw is a set screw and needs to be loosened to adjust the valve. Others are adjusted by the screw. Either way you might need a larger driver the break the tension on the screw. Factory set it can be tight.

Have a model 31-250 drum sander hard to adjust height of table

Here's a link to the online parts diagram and list, and here's an online manual you can download.
Check the lock nut adjustment on the elevating mechanism; you may have it too tight. Have you tried cleaning and oiling (use 30wt) the elevating screws? If that's all ok you'll have to realign the elevating screw bushings.
Check and adjust the table support plate adjustments to level the table.
As far as I know, there are only replacement parts available, but careful adjustment could do wonders for an older machine...

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
If I've managed to answer your question or solve a problem, please take just a moment to rate this post....thanks!
