alexitbe Posted July 6, 2017 Author Report Posted July 6, 2017 Hi jimi, As with most things I buy, the fur machine is an old DDR model by Textima. One day I will sit down and work it out.... No the Frobana is not screwed down, so as you say that should help... I am just scared of messing up the timing and not having any marks to go back to... I should be less of a coward..:) Cheers Alex Quote
Members jimi Posted July 6, 2017 Members Report Posted July 6, 2017 yes! but take pictures before you loosen anything? can you see the shaft underneath?? Quote
Members jimi Posted July 6, 2017 Members Report Posted July 6, 2017 (edited) they usually come bolted to the pine wood base and have a box lid with a key to lock. mine has this missing, but if your machine was without the base then maybe that is where it got knocked? underneath. iam almost 100% sure if you can see underneath then you will find the problem right away."yes they came on a iron stand also" Edited July 6, 2017 by jimi Quote
alexitbe Posted July 6, 2017 Author Report Posted July 6, 2017 This came without a base... So you give me hope.... that there is a simple solution... Quote
alexitbe Posted July 16, 2017 Author Report Posted July 16, 2017 So I finally did this and I will try and explain. As the feed dog height is rotated, the accentric also rotates. The accentric forces a horizontal bar left and right. This bar is angled so that the vertical feed-dog moves up and down as the horizontl bar moves left and right. The problem seems to be that the accentric was not in the right position, so that the minimim feed-dog height was on the middle setting and not at the lowest. The turning or saddle point of the accentric ie minimum, was at the middle setting and either side of that the feet rose higher. After adjustments I now have a feed dog height of 2.5 mm on lowest and 5 mm at highest setting. I would like to be able to drop the whole thing down 1mm, but I have not had time to work that out. Anyone have any idea B moves up and down adn what would happen if I moved the nuts? Sorry if I have not explained it very well. i simply do not know the proper terms for the parts. Cheers Alex Quote
Members jimi Posted July 16, 2017 Members Report Posted July 16, 2017 Hi Alex, have you checked the size of your feed dog? new the two teethed one should be 15mm total and the knife type13mm. Quote
alexitbe Posted July 16, 2017 Author Report Posted July 16, 2017 Hi Jim, I have not checked the size of the feed-dog and I guess I should do this next , since you think it is not a standard part. I will then compare it to your measurements. I will order a knife part next week, as I am a little pressed for time at the moment and I would like an original part. Also, I will use it for making shoes so, I need the knife so as to be the stitches well into the sole. I am pleased that the feed-dogs are almost fixed and the shuttle tension issue has taken care of itself with thicker thread. Cheers Alex Quote
