Box Stitch Using Needle And Awl Machine

[rmr]

Thank you.

How difficult do you find it using your machine to do a box stitch??

Pics as promised. Foot and plate (that I rarely use)

In your pic, it looks like you are running the item being stitched on the right hand side of the foot, inside the throat of the machine. Is this correct? I see you also used a raised bottom plate to achieve relief on the bottom.

On my Union Lock, the open or ground off part of the foot is outside. The bulk of the item being sewn goes outside with only the seam being on the inside. As the foot sets in the pic the front is on the right, inside on the top. As for the raised plate, in my work it is rarely necessary which is a good, no a great thing because deploying it means adjustment of the takeup so that the lock will be higher up and thus in the work and not balled up on the bottom and then returning it to 'normal'.

I have a sneaking suspicion that we may be talking about different things but when I use this foot I can sew at normal speeds with no problems and turn sharp corners or go around outside curves just like it was flat work.

Oltoot, I'sorry but are we talking about the same thing here? We are talking about sewing two pieces of leather together in a 45 degree angle. I'm not sure how this will be possible with your attachment,without the use of force that is.

I'm sure a needle and awl machine will be the best solution for this seam. However,those are not available in my part of the world.

Oltoot, It seems we are not on the same page. I too have a Union Lock and have the single toe feet for stitching right next to an object or edge. The raised bottom plate is great for stitching stirrups, but as you stated, setup requires a lot of adjustment to raise the lock above the plate and to be hidden inside the leather.

What we are referring to is a fixture to allow the machine to stitch the 90 degree corner of a case with the thread passing thru at a 45 degree angle. This requires the bottom of the foot to be angled shallow on the outside of the machine, and a bottom plate that is angled low on the left. This allows space for a square corner of a box to sit under the foot at a 45 degree angle and the stitch to follow around the box. this was popular for binocular cases and camera cases in the '40's. It requires that the leather be beveled at 45 degree angles and assembled to create a square (box) corner. It is quite difficult to do this kind of work well, and nearly impossible without the proper attachments.

The picture illustrates the attachment foot and bottom plate that is needed for box stitching.

this is an item Im tying to sew on a machine- I have the attachments sold by Campbell Randal- just haven't tried them yet

Now we talking Keith,

I take thats a Union Lock attachment. I am grateful for any pictures and ideas. I guess I have to make this attachment myself, because the Ferdco one is not available anymore. (I have checked with the Hoffman brothers).

I am thinking about making a "hybrid" between yours, the Campbell R and the 441 attachment. I already have a drop down roller guide that I can make a new angled guide for. Then I can make a new angled needle plate out of aluminum (your kind of style) and use a bent right toe paddle foot with an modified inner foot. I do not know if a adjustable lower material support like on the 441 attachment is necessary, I think I will find out with some trial and error anyway. A Ferdco (441) pat. lower needle guide will come in handy when there is no space for a feed dog. There will be allot of outward pressure on the needle; causing the 441 to skip stitches. I cannot afford buying/shipping a CR highigh liftom the USA, so I will give this a shot and see how it works out.

Thanks

I think you will be able to sew the top and bottom on that case with ease. You would normally need a machine with feed of the arm for the long cylinder case seam. I wonder how the attachment will work on this seam, its not a 90 degree angle anymore. It looks like its been done with the same attachment, thought.

Trox, the pics I posted are attachments on a Randall machine. I have a few other parts that are variations on the theme. I'll post more pics tomorrow. I believe you could modify a set of feet on your 441 clone and you would need to make our modify a lower plate to have at least a 30° angle. You should not need to modify the work guide. Needle deflection will be the greatest hurdle. Joining a steeper bevel on the right our inside side of the needle will help drive it straight through the leather with minimal deflection. Uniform feeding may also be a problem without the assist of lower feed dogs. A larger needle may be necessary for less flex. Good luck!

Thank you Keith, I look forward to see the other attachments too

Thanks
