That is what it is called over here Al Dissolvente Universal, maybe Acetone would be the equivalent?? not 100% sure?? maybe something like this.. https://www.caramba.eu/en/products/universal-cellulose-thinner-with-acetone-ready-to-use/

I wish i did have the talent and the skill Al lol.. when i get the machine rolling again i will let you know. we were going to try a new type sole first, it has a thin sheet of foam under to help keep things soft. when i try one and it works good i will let you know Al. not sure about mineral spirits though?? the dissolvent is pretty strong? but not as strong as paint stripper. i would use this for thinning for example nitrocellulose varnish and the likes. and would work for thinning oil based paints. hope this helps?

Hi Folker and Uwe, Just in case you did not see the SV post, i never noticed that in one of the 45k topics (which is on the SV topic) the old 1907 book with the different types of machines was written on by someone (possibly around that time) who put up the prices in pounds and dollars and also wrote the type of machine it was before and after. and a lot of them before hand were SV models according to who ever wrote the notes. this brings me to think more like Sample models instead of Special models because they seemed to be given their class afterwards?? they seem to have launched a certain type of machine possibly looking to see if it was accepted and then tweaked it and give it it´s new class number?? ( which also at times got superseeded by another machine) example the 45k64 was an SV 49 then 55 model before it changed to 45k64 then was superseeded i think by the 45k68,69,71 type as it shares the same plate setup as the 68 i think it was which is not repeated in any other class?? anyway...just a thought a no real proof if this??

Good to see that it works fine Al. i used universal dissolvent, i am sure you have that over in the states. it is what you use to thin down varnish and the likes?? not turps.

Great job on that one Folker keep that old iron going... haha. and that is a very neat looking type of patcher! they look way better than the modern ones?.

Al, have you tried cranking up the tension little by little on both units??

Hi Al, here are the illustrations meantime that were uploaded in another topic. if you have the dixie pdf then that copy Sup`des this one k3351. and this one Sup`des K2268. if you do have the dixie copy then you were right, that stud is not there nor the disk #17547? on the subject of the loop, i`am not sure about the thread and the paddle commented by wiz and folker?? if you look in this post for the 45k68 the thread used in the machine looks like b-nylon and it does not seem to have been threaded through that plate with the springs on the cover. and it looks like it has sewn some stitches?? then in the other picture the yellow thread is through the plate?? that is why i said in the first post to try maybe a smaller needle and thread?? like folker said if you have a nº 26 needle in and the thread passes freely up and down the groove on the needle with no friction from the leather then i would imagine you will not get any loop to form?? aren´t old machines fun when they do not cooperate! I think the stud and roller on your machine that moves with the needle bar does the same thing as the above tension assembly with the spring. try to push a threaded needle into a piece of leather by hand and then pull it backwards, you should see a loop appear? yes i think the three sizes of knife will have to do with the thread and depth of cut Al, well spotted i will get some pictures of the face plate but it is not the same as your 45k69 it is the same as your 45k25?? yes Al, thanks. i did make that two-teeth feed dog. this is a singer one...

forgot to put up the picture

I think the dealer in the US for FAV (Fratelli Alberti) is campbell randall ??

not easy to see but you can make out that the disk is closer--

Hi Al, no i have no knife for the plate i made up. i did not get around to making the feed dog either. it seemed a little confusing how the knife worked and how deep it would cut etc... so it was parked.. the one with the two teeth on the right worked great considering it looks really rough once lined up with the stitch length and you don´t hit any tight curves, you don´t really see any marks at all underneath. anyway your tension stud looks like it was changed because the one in the parts list # SS439 has a short length of body from the thread to the disk. the one you have has a longer length of body, that is why that disk is so far away from the thread path. i will upload the numerical parts list for you. .

Oh yes Folker, Al has the bug you might have to sell your car to make way for the other 5 or 6 machines to come! very nice looking machine there Al. as you can tell from the parts book it was for sole stitching and the needle plate had a knife that fitted in that channel in between the teeth of the feed dogs to cut a channel in the leather to sink the thread in the leather #95111. i am just guessing but that disk with the hole on the side #17547 where the thread passes through after the first set of disks, would make more sense right after the disks . it seems to be too far away from the thread path?? on this one there is no thread take up lever spring, instead looks like the roller and stud moves up and down with the needle bar. #91764, 91787, 91788. i would maybe try with a smaller needle and thread first?? the thread path looks right to me? and yes as folker said, 1 1/2 times around the second tension unit with the roller. tell us how you get on Al, regards jimi.

the 45k64 would have probably been superseded by the 45k68 or 45k71. these were the 45k class for sewing boot soles, like the old 64. they had a foot that lifted to enable you to pass over various thicknesses of leather. there would be a lifting cam on the thread take up cam which would lift the presser bar or the foot if you like. here are a couple of 45k64s where you can see the wax arrangement and the spring and gripping bracket. the last picture is the foot and throat plate on a 45k64 that appeared on the 45k68 and 45k71. the parts list book for the 45k68,69,71 is from 1927 so possibly your machine will be from around there?? what is your serial nº? have a look here.

for anyone interested in more S.V. information, in this post above if you look at the older singer book it will show the changes of some of the 45k machines and the models they were superseded by.

Hi, the 45k64 was a drop feed cylinder bed, lifting presser foot. for stitching boot soles to welted uppers. fitted with spirit heating apparatus for heating the shuttle when stitching with prepared wax thread. supersedes 45k55 machine. (formerly known as 45k.s.v. 49) i have uploaded this information in an older topic. you can see this information in the book from 1907. i do not think you will find a manual for your specific machine but rather a general threading/oiling etc.. manual for flatbed or cylinder arm machines. looks like you are missing the lift to your foot? all the best.

maybe this could help...

I think the 45ksv99 was the later 45k92, the only difference i can see from the normal 45k1 is that it has reverse if you need to know anymore just ask as i have both of these machines.

I reckon using thinner leather would help the wallet not springing open too much. you seem to have very thick leather in the picture on your wallet, this could be the reason it is wanting to open a lot. all the best, jimi.

Looks very good and nicely stitched. i also agree with you, leather is looking thick. i would investigate skiving the edges. well done Darkgoku.
