I had a guy bring me coffee bean sacks and use them to insert his seats.

Feed dogs are easy to replace. You shouldn't have any problems doing that.

Speed should not dictate stitch length. Stitch length is a function of the movement of the presser foot and the feed dogs. There could be a number of things causing your issue. Improper presser foot pressure, worn feed dogs, improperly adjusted feed dogs. If you don't feel comfortable trouble shooting those things you should have a professional take a look at it.

Unbolt the hinge from the cushion.

It is done by hand.

I have had good and bad experiences with them. I have been dealing with them for at least 25 years. I have found it is best to ask if the material is "in stock" and when will it be shipped? Customer service is not one of their strengths. I would suggest giving it a shot. Trust them until they give you a reason to not trust them. Good Luck!

Nice Job, nice fit.

I also use a box. The horse does look like it would be more stable. Great idea.

I have made these and fuel tank covers before. I usually use landau top material.

just post a picture of the materials here someone will give you the Detroit numbers to begin your search.

Have a look in the glove box. It may still be attached to the glove box door.

You are welcome! Looks better, you are still stretching the trim piece a bit. You are on your way.

Sew the welt to the trim, not the insert. Put relief cuts in the welt so it will go around the corners flat. Give that a try and see if the results improve.

Post a picture so we know better what part you are referring to.

Katzkin and Roadwire use a docuseam machine and do periodic testing. They do not test every style and material. I cant say for sure but I think they are doing what they can within reason to help cover themselves if someone brings a claim against them.

I have never heard of anyone being sued caused by an improperly functioning airbag due to a seat repair. Like I said before it’s a risk, if you want to take it. I’m sure sooner or later someone will be dragged into court and made an example of. It would be much easier if it were in black and white.

It's all about if you are willing to take the risk. Chances are the airbag will still deploy even with normal thread. But will it deploy fast enough? Since I work for an OEM in trim development I have been in many meetings concerning airbag deployment. Its not enough to use the correct machine and thread and have it documented. To meet MVSS the units must also be tested. If there are any changes made to the seat cover (thread, materials etc.) validation testing must be done again.

Chances are a seat you have sewn an airbag seam on will never need to deploy, and if it does or doesn't deploy maybe you wont be dragged into court and blamed for a failure. Worse yet, held responsible for the failure. It only takes one time, to me its not worth the money I would make repairing an airbag seam. I know it sounds like a lot of BS but if I were in an accident that required the airbag to deploy I would want it to work as it was intended.

That's the way it always works. It can never be the one on top.

I contacted our leather processor/supplier (Bridge of Weir) and they store all of their hides on wooden horses. No more than 150 hides per horse. For long term storage they throw a piece of plastic over them.

I used to have that problem in that the suppliers would store the thread in a hot environment in the summer and if the thread had any wax as lubricant it would melt and stick the thread together.

Serafil is the Poly and Serabond is the Nylon

I buy direct from Amann.

In English it is called a seam ripper.
