COWBOY CB4500/441 NARROW FEED DOG + NEEDLE/THROAT PLATE???

[Darren Brosowski]

The narrow foot set would make life easier as the feet are in line with the needle.

We have these in stock.

@Darren Brosowski Do you have any pictures of it mounted to the machine or maybe a video clip of them in action? Price would be cool, too. It's hard to make out details with the strong shadows in that picture. I may have to take skinny inline feet  off my to-do list.

Thanks for the thought Darren. Are these the feet you sell for stitching around boots and such? In an application where the job is quite stiff I expect these would be handy but the problem I'm having is where the softer leather deflects down the hole at the end of the stitch when the dog foot drops down. I have a couple of more pictures that should show what I am saying more clearly I hope. Be that these look quite bad I have to say after getting the machine all set up and readjusted I have not had one missed stitch or even a knot pull to the top or bottom so far. I might get to like this machine yet. For now until the new dog feet and stuff arrive I have ground and polished the edge of the roller guide to help it not scrape against the edge so badly when the dog foot comes up. I expect to finish this batch of 60 tomorrow and with a bit of luck I will have what I need before the next 200 they want.

First picture shows how the job sits when needle enters.

Second shows how a 2.5mm piece goes down under the needle plate at the end of the stitch when the dog foot goes down

Third picture shows what it does if you are not holding the job in place. As I said like a drunken rocking horse.

Cheers Brian

I had the same problem stitching some of my wallets with the CB 4500 until i had another needle plate made that was a bit narrower and i shaved off a bit the feed dog to fit properly in it. I am using the same set up as you as far as needle/thread combination and same leather thickness and never had that issue anymore.

3 years ago i posted pictures of the new needle plate and as far as i remember , few forum members  bought them and were happy with the results.They weren't as fancy as the ones posted by Uwe but they work . 

If i were you , i would probably stitched this lot by hand just because there are less then 15 stitches at a time. A Tippman Boss would be great for these

Here are the pictures

 

Thanks for that LeatherLegion. I thought I was going to have to do the same trick but I think this set from Uwe will save me the effort. You must be one hell of a fast hand stitcher. I think I could do the re edging a fair bit faster than I could do it by hand. Can I ask if you shaved any off of the tension disk separator to give a bit of room for the foot to lift without dropping the thread tension?  Most of my other machines allow up to 3mm foot lift before the thread tension gets released.I did and as I stated earlier it enables me to lift the foot a little and  turn corners without getting any bottom loops etc. Regards Brian

[Darren Brosowski]

Silly suggestion maybe but have you tried raising the feed dog?

I went back and re read the post and as always learned more. 

Good pickup Darren

On my behalf, im on this labor day Holiday stretching for an excuse.

( cough cough Im readjusting mine a bit )

Here goes: the walker foot recently mounted has the raised area for thread stitch bury.  Anyway I thought it worthy on holiday here. Thanks for the tip, Cheers!

Recently in a post on these sewing machines Solar LeatherMachines, kindly put up a link to their webpage where you could find an English version manual of these sewing machines. http://www.solar-leather.com/supporthelp/

I have been considering making up a narrow dog foot and throat plate to do the finer leather jobs. I tried the narrow slotted plate without feed dog and found several problems, one being that the stitch length dropped back considerably which was not such a big problem but the reverse suddenly went to making no sense at all. I went looking all over the place to find a solution before going to the trouble to make them when I came across this interesting bit on the last page (page 21) in the Instructions Manual & Illustrated Parts Catalogue

#7441-09-0092 Narrow feed dog: work together with 7441-01-0064, for sewing very small borders on hard material, like suit case, furniture, instrumental cases, chairs etc.

7441-01-0064 Narrow throat plate: work together with 7441-09-0092, for sewing very small borders on hard material, like suit case, furniture, instrumental cases, chairs etc.

I have not been able to find any pictures or diagrams of these parts and was hoping someone here may have a set they could post a picture of or have some information about.

Because of the large drop of the dog foot in between stitches I have found that when stitching close to the edge that the job sinks down into the hole and ends up going along like a drunken rocking horse making it quite difficult to keep all lined up nicely. When the edge guide is up close the job wants to come back up and lift the guide which then wrecks the edge coating as well. I have an urgent order to get out this coming week for some personal alarm pouches for one of our correctional centres and this problem showed up whilst I got into stitching them up so I have taken a few pictures to help see the problem with the standard feet I am using. It looks like I will have to sand back and re edge now.The thickness combined is a bit over 4mm or around 10oz and the thread is 20m or 138 if you like and needle is Schmetz size 23 794LR.  I hope that someone here can shed a little light on this and also I would like to ask who else would like a narrow feed dog and throat plate set.

Regards Brian

Not sure why reverse would play up with the slotted plate as the only change is not using a feed dog. If you have a spare feed dog you can grind the top off it so it fits under the slotted plate and try that.

I know you are handy with a grinder from your work on the 801 roller feet

Thanks for the thought again Darren. If I raise the feed dog any higher then it will hit the roller guide.If I then raise the roller guide I am back with he same problem with more of a kangaroo hop thrown in. Are the  7441-09-0092 Narrow feed dog and throat plate 7441-01-0064 Narrow throat plate able to be bought or not? Do you have in pictures of them? I have to say I'm a bit surprised that none of the dealers here have any answers to this as yet. Regards Brian

I did consider doing that but the drag of the material over the plate in comparison to the getting the more positive assistance of using the dog foot made me think to look for a better solution. I am a lazy B at times and to be honest and although I could use a smaller machine  I hate changing bobbins which is a big reason for buying this machine. I am 3/4 finished the job here and am still on the same bobbin. Although many here on LW make heavy holsters and saddlery work where these issues would not show up there are also a lot like me that make handbags and wallets and such. Check my followers in my profile if you like.This machine does have the ability to cope with these things easily but I am not sure if the dealers can at the moment. I hope that I am proven wrong.
