Frank Zika did an article on the Zischang triggers with at least one drawing. I'd get ahold of Laurie Gapko at the archives he should be able to make a copy of the article for a reasonable price.

Yea! I have that same picture, beautiful. I believe that was posted by Mike Petrov up in Alaska Before he Passed. Regards, FITZ.

Dales,
I don't want to rain on your parade but there is only one way you will get the dimensions of  Zischang DST's for a Borchardt action and that is to find someone who has an original rifle with the DST's fitted and borrow them and do the drawings yourself.  That's what John Wills did to make those DST's in the above pictures. I have been trying for 12 years to get a set of drawings but those I have by Frank Zika and another sheet allegedly copied from an original set by the Moeller Tool & Die Co are both so poorly detailed as to parts shape and dimensions that making a working set of DST's is impossible and I am speaking as a fully trained lathe and milling machine operator. There simply isn't enough dimensions from which the missing measurements can be calculated.

I understand that Laurie Gapko the ASSRA Archivist has these Borchardt Action Drawings by the above named Co., and you could ask if the DST drawings are included. No harm to try. A full set of drawings costs $10.00 in A4 size, these can be enlarge beautifully to A3 or A2 by your local photocopy shop.

Over the years I communicated with both Michael Petrov and John Wills on Borchardt's and John kindly furnished me with drawings of his own making of the Zischang custom Safety for his DST's and also how to make a Long Range vernier sight for the Borchardt which requires special tooling to be made by the person making them. Shortly before he passed I sent him my usual monthly Email chatting about this and that and I asked him if he had a set of Borchardt DST drawings. He replied he had, but wasn't doing anything in his workshop at present as he wasn't feeling well, however as soon as he was better he would scan the pages and Email them to me. Three days later I read of his passing. Joe Do., helped his widow in the disposal of the firearms side of Johns estate and I Emailed him over a year after Johns passing to ask if he had come across the DST drawings. He sent me the drawing posted above, stating that was all he had come across. What happened to the fully dimensioned originals is anyone's guess. So no complete drawings seem to be available unfortunately. If I was you I'd give up on making them yourself. But you don't have to take my advice.

Harry.

Rodney:
