  1. I'm not sure of the name but I use this type of clamp http://www.google.com.au/search?q=clamp&safe=off&hl=en&prmd=ivnsp&source=lnms&tbm=isch&sa=X&ved=0CAYQ_AUoAWoVChMIpNjKnrm8xwIVYtumCh2GggSA#mhpiv=13
    One side does on the bottom back of the mabarta, the other on the front upper titura and it pushes it back in place so titurah elyona and tachtonah will be flush. You can even use it while you sew, and overcompensate on the other direction so when you release the clamp it will be perfectly centred.

    1. the type of clamp is called a Bar Clamp. The link above isn't good, please google "bar clamp".

  2. A clamp, even after sewing, will likely not make the upper and lower titura permanently flush. You'll most likely need to glue it once you get it lined up. If it's still off then you'd fix it by sanding. One who is experienced with batim work can easily handle this. As is, it shouldn't be used.

  3. I don't think you understand the type of clamp I refer to. The link was bad, it's called a Bar Clamp, you overcompensate so that the mabarta is pushed so hard the non extended part of the titura sticks out (well) past the more extended side . If you do it for too long or too hard you may end up reversing which side of the ttitura sticks out more. I find this often works even without glue or shaving afterwards.

  4. Please excuse my ignorance: what is the Halachik problem with this? If each part is "rabua" why must they meet?

    I am wondering about the Halacha. Not aesthetics or practical. Just Halacha.

  5. Thank you Eli, I'll just give it to a batim macher.
    YY I was wondering the same thing but in zichron Eliyahu he says it's a problem according to some reshonim. BTW according to a''r the titura elyona is part of bayis as he says to sowe the titura with the bayis. Correct me if I'm wrong

  6. I've been using a clamp (I'll provide an image in a new post as I don't know how to add an image to a comment) for years and it's widely popular among those who work with batim. On one side it has a perfect indentation into which the edge of the titura fits enabling one to adjust the titura. However, even after overcompensating, the titura will often slide back more than to the correct position again leaving a "lip" or "step", hence, gluing it in place once you have it in the desired position is strongly recommended.

    I have a number of bar clamps as well. The ends are soft and it works well when I add a little glue between the bayis shel rosh at the bottom because it doesn't affect the paint on the Shins. I only slightly tighten it slightly so as not to affect the finish of the Shins and so the glue doesn't go too high.
