hey, guys, I'm making watch strap, have been looking for tube to put on strap, can't find though. anyone sells it or know where to get? always thanks leatherworkers for help

pcox, you mean you have different bobbin case for different size thread, that sounds a good idea, then don't have to adjust bobbin case tension again and again.

tricky tricky! I lightened bottom robbin, now is better. so everytime when sew different fabric, need test. as mlapaglia said " It is a balance between the bottom and top. On my Boss I have a light bottom tension and then adjust the top until it pulls the two threads into the center of the hole." before yesterday i only knows that just need to adjust top tension, didn't know that also need to work on bottom robbin. first class after got my baby! Thank you guys! I love leatherworkers here!!!

that's cool guitar!!!

guys, is that stich right on the back of leather? still wondering if I did something wrong.

Thank you dirtclod, just tired loosen the top tension, almost no tension, is little bit better, but still can see " front top thread " on back stich. is stich should be like this on back? or should look same as front stich? nice and neat. I think on back stich should not see " front thread " , right? maybe I'm wrong ... m.. I using top thread #69, robbin thread # 69.

gusy, I start to practice sewing now. I got a question: yesterday I sewed with 138 thread on leather, stich on front and back both look nice. today I bought 69 thread, changed needle to #20 as pfaff manual says, tighted tention ( is tightest already!) but back side stich looks not good, see the brown thread on picture, can see grey thread ( is top tread ), top tention is already tightest, where is not right?

Ash, you have newer 1245 or pfaff 1245-706? is your stich not straight sometimes?

I tired both presser lifter this weekend, think both good. and Wiz, 8 foot pedals and 9 knee levers! my god! ^.^

I got the machine! Wiz! love it! should get new thread, got old thread from nice owner, always stuck and broke. Wiz, this pfaff 1245 have nice stich, when owner showing me + sewing by myself, stich was beautiful and STRAIGHT. tonight I tried on soft leather, stich was not straight sometimes. is because I didn't hold leather right? or ... this afternoon when I test at owner's place, we tried vege tanned leather/heavy thread, was really beautiful and straight. I wondering why I tried on soft leather tonight and stich was not straight sometimes. mmm... also Do I have always to adjust tention when I change fabric/when add more layers? about stich lenght, is "thinner fabric narrower stich length? thicker fabric wider stich length"? pfaff 1245 Needle Size Information: #207 top thread and #138 Bobbin thread use a #23/160 needle #138 top thread and #138 Bobbin thread use a #22/140 needle #92 top thread and a #92 or #69 bobbin thread use a #21/120 needle #69 top thread and a #69 bobbin thread use a #20/110 needle think I will not use thread over 207, but can I use thread under 69? So happy and really thank you guys here for helping me all the time

Thank you Wiz This is pfaff 1245 machine, on the reverse place has number from 0 - 6 mm for stich length, it means the longest stich of this machine only can go 6mm ... ? seller said will adjust the stich length, I will I go test again. try if can sew 5 stiches per inch. should I ask him to adjust to 10mm as longest stich length?

Wiz, I went to try this machine at noon time, it looks 80-85% new, I think is in good condition, but not quite sure since I only know little bit about sewing machine. I didn't buy it, three reasons, seller will do it for me in this two days. 1. servo motor, he's going to put consew 3/4 servo motor for me ( will tell him to demonstrate it running at 1 stitch per second ). he asked me if I want to get "something" for needle, let me explain if I understand what he meant. this " thing " will help to lift up needle, don't have to wind machine wheel ( the wheel for belt ) to lift needle up. he will put it on wheel. if want to have it, pay 30 bucks more. do I need it? is it good to have? Wiz and guys. 2. important! this pfaff has reverse also can adjust stich length, reverse works good. but stich length, ok, this is what I did. there are 7 numbers for stich length, 0, 1, 2, 3, 4, 5, 6. I put at 6, is not so long, seller is really a good guy, he brought the stich length disc and measured the stich length on leather, is about 4.5 wide, not really 6mm. then I tried to put at 4, stich length on leather is shorter. then I wanted to push to 3, 2, 1, but that stick can't go up to 3,2,1,0. so means now this machine only has 2 size of stich length, 6 ( acturally is 4.5mm ) and 4 ( I didn't measure if stich on leather is really 4mm ). seller said he will adjust stich length for me, can't push up to 3, 2, 1 is because that nut is not smooth. I attached photo here, might help you to understand what I said. ( bad english, ehhh ) I think have good/right stich length is important, do you guys think so too? cause if sew thick stuff like leather, we need long stich length, right. if sew thin fabric, we need short stich leagth. so to me, correct stich length is important. you guys also will test/measure to see if stich length is right? 3. extra basic things, seller will give robbin, needles, foot, thread. what else things can I ask to have since he might have/give? ok, I keep searching/studying online, always thank you guys for help

Thank you Wiz and Tom! so much so much! I really learned a lot from you guys here! Yes, I went to try this machine today, is foot lift pedal (shoe shaped) is hooked up to the lifter arm on the back of the machine. and is good to hear from Tom about it, I saw a lot knee level lift, so naturally thinks knees level lift maybe better than foot lifter. Will ask more question in another thread now.

Thank you guys for your reply, the machine I'm going to try doesn't have knee level to presser foot, but has a " shoe shaped pedal", is shoe shaped pedal also for lift presser foot? mm, I think answer is yes cause Spinner and studioN said. just wondering do I need to change it to knee level lifter? I attached photo here.

Thank you Wizcrafts! always always I'm going to try a pfaff machine this noon, seller said is 3/4 horsepower consew servo motor, is it good or good enough for sewing leather? which one should I get? since servo has different type, ( is a 1245 machine. )
