    A big thank you again to John for measuring everything. Making all these parts is a lot of work and time, but I'm retired now, so I have the time and I don't have the kind of disposable money DoALL will want for these parts, so my path is clear. I will make these parts this winter. I will make the shrouds by cutting them out of bar stock, probably aluminum and then hard anodizing them. I have been concerned about the cable from the beginning. That's why I asked John to identify it. This thing was designed back in the '30s, so steel cable was all there was then. Today we have aramid fiber rope that has very low stretch and is lighter and much easier on the hands. The loads are very low and well within the capability of aramid rope. I'm inclined to go that way. I also like the idea M.B.Naegle came up with. I'm pretty certain DoALL will want a fortune for the pusher, Building a .DXF file and then cutting them from 1/4" sheet is the way to go. Even if a file does not exist, a photo and overall dimensions would be enough to extrapolate adequately to build the file. Cutting the sheet could also be done with plasma, water jet or laser. I don't think it matters so much. What would matter is a survey of interested parties that may be interested in these parts. I'm pretty sure I'm not the only one. In the case of the pusher, it would make a difference in cost. So, who else wants to play?

    Shrouds...

    51 years ago in the fourth year of the apprenticeship we were required to design, build and test a die. I made a pile of these covers from brass - maybe I can find them

    They were never trimmed - all still have a wrinkly flange attached since I did not have enough spring pressure on the hold down as the "cup" was being formed

    They are a bit large on the OD but maybe can be made to work

    Shroud
    I haven't stopped thinking about those cable guides either. The bottom of a stainless cup or container. I google stainless cups , dishes , ect.
    https://www.amazon.com/FineDine-Stai...0409051&sr=8-4

    Here are some cups the bottom could be cut off but the gauge is probably too thin. Getting the right diameter with straight sides is what's needed. A black iron pipe cap of the right diameter trimmed up in the lathe ?? To Brittle?
    There is something out there the right size.

    John, That's a real test to make that type of die as a class project. I know a machinist that makes trim dies that made a shallow progressive die for a condensate catch pan. A one hit in the press. He finished it but said screw that I'll build trim dies.

    Your class project may work though.

    For those of you who want to restore a DBW 1A blade welder. The lamp it has is no longer available. In a previous post I identified the bulb required as a E11 base lamp. It is not, it is an E12 base lamp and I have bought a compatible LED replacement from AMAZON. It is a 6W lamp, 75 watt equivalent and it fits within the original shade, no easy task. It is sold in pairs for $15.99 and is 220 volt.

    I received confirmation that these parts are no longer available from DoAll with the single exception of the Pusher/Work holding jaw new PN 5-013007. I have not yet received a quote.

    The pusher plate itself would be a great candidate for laser cutting. Just saying. If someone sends me a drawing, I'l be happy to get a price on some as a group buy. [email protected] I just had some 3/8" thick parts laser cut and they came out very nice. Dan

    I received confirmation that all these external parts are no longer available from DoAll with the single example of the Pusher Part # 5-013007. This is still being made. The quoted price FOB is $332.60 as of yesterday.

    I have been digging through some parts I saved with several old DOall saws last year. The saws have been sold, but these parts have been in hiding. There were 20" and 16" contour saws, in rough salvage shape. These parts were in a box labeled contour saw parts. At one point I had found a picture showing the part with the worm gear/universal joint but it eludes me now.
    Can any of you ID these? I'd like to post these for sale and send them off to someone that needs them. img_0304.jpg

    From the photos you included, no it would be very difficult, but it look like the pusher is not only in rough shape, it appears incomplete.

    I know this is an old thread, but this is an update. I have finally received all the parts from the US to complete the build for the power feed that has been missing it seems forever. I ended up acquiring Aircraft control pulleys as John Oder originally suggested way back when. I found new old stock Ralmark MS20219 pulleys one eBay. The specs and size of these is available on the web. They cost me a little over $100 on eBay, which was very friendly. I picked up some 2mm wire from China and stainless end terminals that are for 4mm wire, but I will use a copper sleeve as a crush adapter. I also bought from DoAll the correct pusher. It was $350, which I thought was very steep at the time of purchase, but after looking at it, I understand the cost. It is an assembly of several parts and the main part is a substantial iron casting not easily seen on a photo. It is not easily reproduced as a plasma or a laser cut part. Yes, the price is steep, but I could not make one for less. The rest of the bits I need, I will make thanks to all the dimensions from John Oder.

    class project
    I have to correct an assumption

    EACH of us had to design and build a die and make it work. Others had more success than I

    Yes, this is an old thread, but this has been an ongoing project and I have finally made the very last part. It has been a lot of work. I have been making these on and off as I found time. I have attached a picture that includes all but the chain, chain end connectors and the cable. Please note the cable shrouds are made from 6061-T6 Alu. I will be sending them out to be hard anodized.img_1706.jpg
