I've been dreaming about a garden. I sssssssoooooooooooo want spring. Pressure tension springs will have to do........

I learned about pressure foot quick release tension buttons by accident... I pushed the button and it flipped up - suddenly my machine doesn't pull fabric???? WHAT???????

Ms Igor got her hands on one of the little nuts on the top of a 401 one time and I had to learn to adjust the pressure...

Ms Igor got her mitts on a machine and turn the screw that holds the spring in place and the whole works hit the ceiling all at once... Don't read on if you are faint at heart. nah - just kidding.

There are several kinds of 'releases' for the pressure foot tension. A lot of older machines do not have any quick release they just have a plain old nut up there and you can turn it and set the foot pressure.
NO QUICK RELEASE:

When they refurbished the old machines some times you might see a quick release added. And some times they work fine and some times they are a pain in the a** because they either won't release or won't go back to regular pressure

Then there is the quick release on a Japanese Deluxe with fancy stitches:

The quick release is a nice feature when you want to do free motion. You just pop the button up and it releases the tension on the pressure foot. The old fashioned way would be to turn the nut at the top like on my 15-75 Singer and when you are done you have to re-adjust the pressure. That info should be in a manual. It isn't hard to do but is sure is a nuisance if you want to go back and forth from free motion to regular sewing.
I love my little 15-75 and I added a pop up just to soup her up just a little. Her feed dogs drop under the machine - a lot of the Japanese machines have buttons or a knob to drop the feed dogs. Some machines do not have the ability to drop the feed dogs.

Word to the wise from Tammi:
And a note to self and maybe others... watch how your fingers are placed when you release those quick releases! The first one I encountered bruised me! I must have had my finger in some weird position over the top. I pushed down on the ring and the center sprung up and cracked me right in the top of the first bone as it joins the knuckle. I had that reminder for close to a week. That said... a few years later the lesson has still stuck....

ha ha - SPRING is in the air???
I decided to change the old pressure on my 15-75 in the first pic to a quick release. It is very easy if 'spring isn't in the air'... I put the pressure foot down first. I don't need that thing cocked and ready to fire. Then I took off the nose plate - I wanted to clean in there anyway. Then I started to unscrew the old knob. Well I thought I did - it wouldn't budge. That machine had a lot of varnish on it (old dried oil) anyway I gave it a little oil and tried again to turn it. Finally I got a pair of pliers and got it off. Hard part. Then I cleaned old dried oil off everything and put the new one in. No big deal. Then I adjusted how tight I want the pressure. TADA.
You wouldn't think these fit on the same machine:

When to make adjustment to the Amount of Pressure:

If you find that the fabric will slip when the presser foot is down,
you need to increase the pressure on the presser foot.

If the fabric is held so tightly that the feed dog is unable to move the fabric,
decrease the amount of pressure on the presser foot.

If it is too tight you will see fabric puckering. I had a machine recently that suddenly puckered fabric. I knew that machine worked. I had put on a new foot - made in China - I compared that foot to an original. It was a hair or two higher so putting on more pressure. I don't know if you can wear out feet that way or not but the new one was puckering and the original was not. The original had cosmetic issues.

How I adjust the pressure:
I put what ever fabric I will be using under the feet. I pull on the fabric to see if it holds. If it is too tight it won't pull at all. If it pulls out it is too loose. There will be a sweet spot... It is an art not a science.

Some OSMG told me for practice try adjusting pressure with a piece of typing paper - no needle of course... Put the paper under the foot, try to pull the paper out. If the paper tears there is too much pressure. If too much, loosen the pressure until the paper pulls out. Then tighten it a bit. There is a sweet spot. Then check it with fabric. I usually adjust the pressure until it just holds the fabric. Not too tight not too loose. You don't want to be able to pull out fabric but you don't want it too tight either.

I'm thinking they put a silk setting on the drop feed dog knob or buttons so you aren't supposed to have to adjust the pressure for light weight fabric.
