    bellows questions

    after applying hinge it says to make sure the ends of B and A are level. So B should be shortened because of the hinge width so the open end when resting down equals the end of A? Instructions say to drill transfer holes in front upright then drill 8 holes in front upright D, aren't they the same thing? Also can't seem to find any info on the side braces besides to install them. Thanks for your help.

    That is correct I took a little off of each end of "B" so as to make sure that the end for the conrod hinge would still be thick enough hold a screw well

    Yeah its the same thing just do them like the drawing on page #3 shows.
    As far as braces I made mine of 1/4 X 1/2 and put a block on each end to give clearance. Will post picture to show the completed bellow with brace.

    Before you criticize someone, you should walk a mile in their shoes. That way, when you criticize them, you're a mile away and you have their shoes.

    bellows leather

    Questions before I mess up: in the DVD it appears there is a cardboard spacer under the end flap on C, is it necessary? The card stiffener measurements in brackets for the reservoir in drawing 1 are from C to D?, the others are the outside measurements? When installing the leather you install A to B, then B to C, then C to D? Also should shorten the end stiffeners at the hinges to be 1" shorter than hinge or both end stiffeners shorter? Getting ready to glue !

    Ted the card board in the video is because he was showing a bellow used in the original Topsy and the holes were in the wrong place. You will not need to have it there just make sure your holes have good edges and the ply is smooth and flat.

    The stiffener drawings are showing the different in size. You will need 2 ends and 4 long ones for the res that measurement is in the ( ) Then you will need 4 ends and 8 long ones for the bellows "A" "B" and "B" "C" made to the measurement with out bracket.
    Trim the long stiffeners to be 1" short of hinge area on all hinge areas. The end stiffeners do not get trimmed.
    Glue these to the fuzzy side of the leather making sure there is 3/4" leather showing on the top and bottom edges of all the leathers.
    Start at the front (I stated with "A" TO "B")and glue one edge on then work your way around the glue the top edge on starting again at the front.
    Be sure to NOT get to much glue in the hinge area or your bellow will be glue bound (DAMHINT had to redo mine)

    Hope this all makes sense and I have answered your questions

    So 2 of the long stiffeners at the hinge end of the reservoir and 4 of the others at the hinge end are shortened, do you just chop off 1" of the point and leave it flat? Also when gluing the edges the lower edge of B-C will overlap the upper edge of A-B, must the smooth side of the leather be roughed up for a good glue seal? Was planning on using cereal boxes for the cardboard but I see they are not 1mm. Still searching for something.

    stiffeners

    Yes that is right but first set them in place to see if they need to be trimmed. I had to shorten my boards ("B" "C" "D") to make everything line up because of different hinges than what John had. Thats why I had to shorten the stiffeners.

    Yes you should roughen up the smooth side where the leather will over lap dose not need much tho.

    I found some Crecent brand illustration board yesterday at an art supply store I'm going to use on the next bellows it was the med wt board and measured 1.2mm the back of legal pads are about the right stiffness and I have used them too.

    bellows completed

    finished the bellows, pumps air nicely but haven't checked for leaks yet-a little silicone should fix any. On to the case.

    Ted,
    In the picture of your pump, I can't see the fold on the reservoir leather.
    Is it just the angle of the photo?
