    The 'real' Roscoe design is 3+1/8" wide at the top and front tapering to 3" in the bottom/back. One of the right angle legs is 1+3/4" and the other is 2+1/4".
    Mine is based on a 2+1/2" cube, which I started making before I emailed Roscoe and decided it would work as-is as a proof of concept.

    This drag is extra deep for no good reason other than I had a half-used piece of 1X6 piece wood at the ready. Seems like I always need a flask 'one bigger' but I took it too far and agree it would be too heavy once loaded. I could remake one side shallower or convert the works into a planter or toolbox.

    I had to throw a flask together to cast the bowl. The 1x6 was an old concrete mould, the 1x3 was an old furring strip that had a hole in the side. They were so wobbly I could have used them for a rocking chair. Stole the hardware off another flask and had to hammer the pins to get them lined up. As bad as they were, they still worked to get the bowl done. Never enough flasks.

    Bruce, AKA Crazybillybob hooked me up with these amazing 3D printed Flask hardware
    i told him to sell the files online . I'm curious how long they will last in normal HT1 use. I may set up my drill press get a jig and the Double D broach and a reamer, and sell sets of them... Everyone will tell me they are overpriced "SHRUG"

    @HT1 @crazybillybob
    Nice collaboration!
    Are both sets (both sides of flask) of pin receivers D-broached or just the one side with the other being a plain round?

    PS/Edit: I am still working on the more true-to-size Roscoe patterns, just made the follow board and gating.

    My gating piece was not quite ala Roscoe so I redid it so it hooks over the follow board per the video.

    OK I love What Bruce did for me, but I want to "pro " it up so I priced up tools and parts: first off I could find nothing off the Shelf In SAE so I switched to metric 20MM for Pins
    I apologize for the long links

    One Ill need the Double d Broach: $197

    two Shoulder Bolts to convert to pins : $20 Each

    drill bits and reamers will add another $60 then casting the parts , metal etc.. cost to me is probably about $75
    once I make them I can put them on any wooden or cast aluminum flask ...

    Im questioning if there is even enough value to me... 10 years ago I would have been all over it . any chance I could sell them at $100 a set???

    Thanks In advance

    P.S I have to ask myself people that might find these useful could make their own, and people that might be too hobbiest to consider proper flask hardware essential... I mean I still level flasks to get perfect mating surfaces my rubbing them on my concrete drive way:rolleyes:

    Hard to say. I could see getting a set just to say that I have something designed and made by Burt and Henry, but I would not see myself (hobby guy, non-profit, cheap by nature) converting more than one flask over until I was gaining throughput that mapped to income from them...even if they worked a treat. My guess is that most of crowd here is likely to DIY before buying out. I could be wrong too, others should feel free to comment.
