I have always glued my work together prior to hand stitching....now that I am learning to stitch on my machine....is it a no-no to glue? Will the thread/needle/anything else I can't see get all gummed up and so on.....making life even more frustration while learning the machine?

Thanks for your comments.

It's the same as when handstiching, glue needs to be used to hold items in place as you sew. You can also use small tacks in order to hold things togeather and pull them out as you go.

Enjoy your machine!!!

I will glue most items before sewing just as was said before, to hold everything together. With machine stitching the bottom piece will tend to pull under. If possible leave the bottom piece just a little further out than the top to prevent the bottom piece from pulling back under. When I do not want glue on the item, like sewing purses that I sew inside out and them later turn right side out. I will hold them together with binder clips and remove them as I sew. I buy these by the box full from office supply stores. They work great for all kinds of things where you need an extra set of hands.

Hi, Im new to the site but know a little about sewing machines. What machine do you have and what size thread and needle are you using and alos what type of leather are you sewing?

Rayban...my theory is if you want two pieces held together, why not use the stongest bond possible? So when I sew, it's after I have glued using Barge or Masters cement. Occasionally I'll have a repair item come in that's been glued this way and after removing the stitches, the pieces are still well bonded together with just the glue. So unless you are making something that you want to be able to disassemble easily, I say glue it!

Stichers, it's this Chinese knock-off of a Singer K45 as I understand it....I'm using 277 thread (?) and i don't know the needle size but is about 1/16" thick. Most of my work is two or three layers of 8-10oz.

It seems to be working well enough for me...

but my main concern is the affects of glue on the machine/needle, etc.

Will the glue gum up the needle, hence the thread, bobbin, etc??

Hidepounder,

Where do you get Barge and Masters cement? Is this a contact cement? or is it something for leather?

From the machine I saw you have a Mercury M-120-1. If that is the machine you have you do need to increase the footbar presser and then it will sew the glued leather. You may have to screw it down quiet a bit to get the machine from flagging.

It will depend on what machine you have. What happens is the needle generates heat as is punches ant hole for the thread. The thread will sometimes stick to the glue as the needle takes it down through the hole. The thread then can stick to the side of the hole and cannot let the machne throw the proper size loop for the hook to catch and make the stitch. Try going to one size needle bigger. It gives the thread more clearance between the leather and the needle and will allow the machine to throw the proper loop so it can complete its stitch.

Watch the presser feet when they are on the material as it is making a stitch.

If the presser feet raise with the needle then all you need to do is increase your foot bar pressure by tightening the knob just above the foot bar until the feet do not lift when the needle is coming out of the leather.

Hope it helps

Needle and thread combinations

346 top 277 bottom - 328S #230

277 top 207 bottom - 328S #200

207 top 138 bobbin - 328 S #180

138 top 138 bobbin - 328S #160

i do not suggest you use any size smaller than 138 on this machine

I've never ever had trouble sewing leather that has been stuck together with contact cement or Duall 88 and I use needles #160 - 230. The only time I have had trouble similar to that was once when I tried to use the double sided adhesive tape and gave up in frustration as that used to stick to the needle and I've never used tape since.
