Thanks for that :-)
In all honesty I think the pfaff needs new gears for the hook , when you turn over the machine by hand and rock it back and forth there is a delay between the needle bar movement and the hook starting to move , I've adjusted the gears underneath so they mesh tighter but it's still there to a lesser degree , it's a 145h2 and parts are looking a little scarce and from what I hear the re manufactured parts are equally as bad ! I may try filing the shank on the gears so they can actually mesh a little tighter , I've nothing to lose ! I also think the thread gets caught over the top of the bobbin case locating tooth and the underside of the presser foot plate , especially when there's plenty of thickness of material under the foot , it's as though it's bending the plate , it does seem feeble to be honest and In my opinion these are not in the same league as the singer 211 machines . I thought walking foot was a walking foot but there are so many variations it's a bit confusing at first , I've recently bought a Chinese made juki type replica called a pf5318 and it sews really nicely however it only has limited presser foot lift and I struggle with carpet binding etc and it has a rear walking foot and no needle feed so tight corners while piping or welding as the USA call it's a pain and the machine is inclined to walk off the job if you're not vigilant and ruin your work , the pfaff is front walking and needle feed but has no rising feed dog and the stitch length is limited to 4 mm , which leads me to the opinion that my singer 211 with front walking foot , needle feed and rising feed dog is by far a superior machine for car trimming , sadly it has no lockstitch which is why I bought the pfaff ! I've been doing car trimming on and off for years but never really got involved with the machines but I personally feel that the quality of engineers these days in the uk is pretty poor without spending a kings ransome , so I've been trying to learn a little as I go along but these no substitute for hands on experience ! I think that engineers want to get your machine sort of seeing with the minimum effort and run with your money rather than do a proper job and sort it out fully so you'll have to call them again in 4 months time !
The singer does have a leather point needle in and I always use them in that machine , I'll try another style needle and see what it does , I appreciate if I used smaller stitches the problem wouldn't be as evident but I like the look of a larger stitch if it's visible on car seats etc , I'll drop it to 6mm and see what happens also ,
Once again thanks for the help I'll let you know how it goes 👍
