Have upgraded cranky rusty old 323 for a Knitmaster 360 with all the bells and whistles which I am very pleased with. All the bits are there, and it works fine... most of the time.
Every now and then going from right to left, the carriage just stops with a very abrupt "donk" with a very obvious stop point. Not a tension problem; the yarn is fine, and it's like it's coming up against a wall, so I suspect some kind of metallic issue. It tends to right itself, in as much as I have moved the carriage back if it hasn't engaged with the working needles yet, tried a couple more times and then it runs across fine.
Sponge bar is OK, have oiled it. It usually works perfectly- just perhaps one row in 50 you get this "donk" at a very clear stop point, and it won't move forwards, but will move back.
I wonder if one of the needles is perhaps slightly out of line or bent, and therefore gets in the way of the carriage. I can't see anything obvious. It's always in the same place - going from right to left, just when the carriage is about to meet the cam that trips the row counter (that moves freely also, so not that).
Any ideas on how to track down the culprit?
With no yarn in carriage or on needles pull out to holding position the needles in that area. Check that all are completely straight, all latches open and close easily. An engineer told us to use a new banknote to flip them open and closed. Change any doubtful needle. Hope this helps.
Will give it a go, thanks.
Take the sinker-plate assembly off the carriage.......and run the carriage slowly across the bed......At the point where it stops abrubtly ....you should be able you see which needle(s) is not performing as it should.......Swap it out for a new one.......If you don't have a spare needle.....take one from the end of the bed........You cannot always see needle defects......but this does sound like what is causing your problem....
I wonder if it might be a latch a bit bent? I had one that way and it knit fine most of the time. Takes a keen eye to see the pesky latches!
There was one needle that looked a bit out of line. I couldn't work out how to get it out so I was naughty and just bent it straight again. Very bad, I know, but it seemed to work. *sheepish grin*
Well, I can understand that! We all save in any way we can - in order to have more money to spend on yarn!!!
Have upgraded cranky rusty old 323 for a Knitmaste... (
I found that one side of my sinker plate was slightly higher and slightly closer to gate pegs - only crunched when I went a bit to fast. I have taken the front part of sinker off and slightly bent it and it seems ok now. Think it was caused by me leaning on the table at the front and the whole table tipped and the sinker hit a chair. Thank God it didn't hit the floor!! I am not sure that standard tables can really take the weight of a 260 with ribber
I have been using mine clamped to the ironing board. It's fine normally but I had a go with the ribber on and did what we in the trade called a "dynamic risk assessment" and decided it was just too likely to topple over so I'm going to have a rethink. He won't let me clamp it to the drop-leaf table that was his granny's.... Ikea trip I think.
Years ago I was told that it was wise to rotate your needles. Depending on how often you use your machine...heavy use, once a year take out all of the needles, blow out or vaccum, soak needles in denatured alcohol that has about a teaspoon of oil in it....then lay them out to dry and with a lightly oiled cloth put them back in.
I had this happen suddenly with my brother 270. It was fine; I didn't use it for about a month; it started crashing, and always on the same needle butt. I swapped needles, fiddled and fiddled. One day I oiled the carriage *one more time* and problem solved.
