    Buff well after the dye has dried, before you put anything on top of it. You need to remove the pigment that is on the surface. Adding most any finish on top of the dye before it is buffed well usually results in spreading the surface pigments around instead of covering them. Any solvent will dissolve the surface pigments. Your finishes contain water or alcohol (or other solvents). Tom

    Please read and follow the market place rules. See http://leatherworker.net/forum/forum/70-announcements/ Tom

    You need to also consider the size of the machine head's pulley. On smaller machines, the pulley is smaller than on the larger machines, thus it has a lower speed reduction. I have a similar sized machine with a Familysew servo with built in 3:1 geared speed reduction. I had to add a pulley reduction set too in order to get the initial punching torque required for 8 oz and heavier leather. So I would say from my limited experience, add the pulley reduction set or fabricate your own if you have ability to do so. Tom

    Personally, I would use rouge. I think it works better, even though rogues are everywhere and are less than a dime a dozen. Tom

    Looks very nice. For Veg tan leather, doesn't need to be soaked, just moist enough to allow you to form it. Maybe 5 seconds in the water. Really soaked will take a long time to dry out. Tom

    Forums > Fabrication > Leather Sewing Machines There is also a temporary link from your original post location for 6 days. Tom

    Since this seems more related to leather sewing machines, I have moved it there so hopefully you will find even more answers and comments. Tom

    Just moved your post to Leather Sewing Machines where I think you will get more responses to your questions. Tom

    Reduce your file sizes to fit the size restriction. There are several posts about reducing file size. Do a search and you should find what you need very quickly. Tom

    Here is some useful info on using magnets. http://www.kjmagnetics.com/blog.asp?p=magnets-vs-steel Tom

    Hope all of you and your families have a great year 2017. JLS, you must be getting slow! Tom

    Tannin used in the tanning process, plus iron, makes blue / black spots. (Check out the vinegaroon process used to produce black leather without using actual dyes.) Looks like there may be some contamination with iron filings, maybe from one of the tannery's cutting or finishing machines. Dampening the leather will likely make the spots larger. In your own shop and work areas, try to make sure that no iron filings get transferred to your veg tan leather. Tom

    Contacted the OP. He only wants to sell the whole works as a single lot. Tom

    Everyone has a file limit. Resize your photos down to 800 pixels wide and you can post lots of pics in a single post. There are resizing apps on the web, also ones you can download. There are several posts about resizing if you want to do a search for them to get their ideas and comments. Posting photos here is better than linking to another hosting service. There are many broken links here because web addresses change, and people take their photos down after some period of time. Tom

    Would you fellows mind posting the link? Others would be interested I'm sure. Tom

    Try a medical supply house for a plastic eye cover. Then wet form a leather patch using it as a form. Had to wear one of the plastic ones for a few days a couple years ago. Tom

    It would be interesting to see if there are any bow makers here and what their comment and experience would be. Their laminations are all oriented along the length of the bow. Maybe it has more to do with how much spring. Off topic, but interesting. Tom

    Seems to me I recall a post a while back that they are no longer available. Try a search for them here. Tom

    One piece of leather, split from bottom to a point in line with the screw. Follow my pattern and advice posted above. Cut on the line marked as a fold line. Look real close at the picture you quoted and you can see what is cut, and what is folded. Might be hard to see if you are looking at it on a phone, go to a larger screen, or zoom in. Tom

    That guide on the bobbin case is for doing zig-zag stitching. My Singer 20U instructions indicate it can be bypassed for straight stitching. Tom Edit: On the Singer 20U, the face of the bobbin case is parallel with the arm, not 90 degrees like the Pfaff, so this comment isn't really relevant to the Pfaff. More likely to aid timing when changing stitch lengths and the motion of the walking foot.

    Agree it also says 20 A. However a kg-m is not a Nm. Recall that F = mass x acceleration.
