    Thank you again John. Where do you find all this data? Do you know the diameter of the pulleys?

It is a much better system than my Grob bandsaw that uses an air cylinder and can only cut straight.
    Thanks for that. You are the only person I know that has actually used the feature. I was beginning to question whether my effort to acquire or make these parts was really worth it.

    I used to have the toothy part...may still have it. I'll try to dig for it in the next week.

    Measuring my parts. Pulleys are 2 1/4 OD and their hub has a .375 bore

    More as I get to it.

    I never used it for the first few years I had the saw. Thought about taking it all off then for some unknown reason I tried it. Once I sorted out how it all worked I was sold on it.

    More "pieces" info.

    "see text" in photo refers to mounting stud for central pulleys - it is .375 dia. pulley end with 1/4-20 inside and is 5/18-18 on other end - suggesting this stud could be made from a shoulder screw

    Thank you again John. I now have successfully converted the saw to 400V 50Hz. I am now restoring the DBW 1A blade welder, which had been exposed to the elements for quite some time as well. I completely disassembled it and painted what was painted. The 1A model has a light bulb and shade, which the later models do not, like the Model 15. In any case the bulb socket looked strange and after significant research, I have determined the bulb needed is a 75 watt, E11 base, T8 style. Certainly not a very common lamp. I thought I had a schematic of electrics, but I do not. I tried to determine what voltage is supplied to this lamp, but the wire harness has been cut and I have been unsuccessful so far. I think the lamp power was 120V, but I don't know the source. If anyone has a wiring diagram, it would also be appreciated. I have however, located an LED bulb, 50W equivalent with an E11 base that is both 110V/220V compatible, but it is advertised as a T$ shape. I have bought it, but I'm not certain it will fit under the shade. e will see.

    This is the pusher. I think they usually broke in the middle, (mine did) so that didn't help their survivability at all.

    this system is really for thicker material where higher feed pressure is needed. as moonlight said, he used it on 4" Al. I think for die work it would have been just the thing.

    Thank you John, this is all very helpful. I have just completed the mechanical restoration and painting of the DBW 1A saw blade welder, but I have been unable to find an electrical schematic for the 1A welder. I have them for the DBW 1 welder and the DBW 15. There are electrical differences between the different models. I have not yet found a source for the schematic.

    Cable terminals.

    These two styles may or may not be applicable. The two piece would of course be simpler to make if workable

    The general approach is to effectively grip the spread out cable strands

    The three piece is marked 3/16

    I neglected to say that clevis end of long or three piece job is .22" wide

    Do note the conical item is shown BACKWARDS

    Thanks again John, but can you identify the actual cable that is used? On the welder progress, I developed my own schematic for the DBW 1A but modified it slightly by adding a separate switch for the lamp using the vacant hole on the face plate used on some models as the grinder motor switch. On my machine the grinder switch is mounted in an adjacent hole in the saw frame.

    Probably not. I can tell you what came with machine. .150" OD, appears to be 7 X 19, nicely flexible - but hopelessly used up ON EDIT - forgot to say finest strands are but .009-.010" dia

    Bought a trial balloon from McMaster Carr - 3/16, 6 X 19, .204 dia. and much too stiff for those little pulleys

    A suggestion would be the 5/32 or 1/8" 7 X 19 from Aircraft Spruce. Their numbers in my 20 year old catalog are 05-04400 for the 1/8 and 05-04800 for the 5/32

    I'll probably get the 1/8 if I ever decide to bother with the power feed

    Our DoAll saw is likewise missing the external parts of the auto feed. I've been wanting to get it complete to help sawing through thicker/bulkier items but haven't been able to yet.

    Every now and then I see that people have made reproductions of the material pusher, which is handy even on it's own without the auto feed. We use an old chunk of plywood but the original stepped 'V' plate with handles would be much more functional. If someone has a DXF file of the piece, I'd think they could be lazer'd out of 1/4"-3/8" CRS for pretty cheap with hardly any follow up operations (just add handles).

    Big thanks to John for all the helpful info!

    How would you guys make the pulley shrouds? The originals were die stamped sheet metal correct? I'm thinking about making mine from solid round stock and using a rotary table to mill the slots in place.
