Daswulf Posted September 28, 2015 Share Posted September 28, 2015 Had picked this hand operated drill press at an auction. Looked interesting. Only thing is it seems to have a punch in it and I don't see how it would get changed out. Looks like it would mount to a table or something. The wheel lowers it and the handle turns the bit. Unless someone changed it for a single purpose or just jammed that punch in there, I don't really see the need for the punch in a drill press. Any thoughts?

tdaleh Posted September 28, 2015 Share Posted September 28, 2015 Punch was used to remove rivets on a sickle bar. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted September 28, 2015 Share Posted September 28, 2015 As you can't rotate the end separately from advancing it---it is NOT a drill set up Quote Link to comment Share on other sites More sharing options...

ThomasPowers Posted September 28, 2015 Share Posted September 28, 2015 (edited) So one of those pieces on the top rotates a shaft that goes down through the threaded section?Or does just the bottom piece rotate so it can remain stationary as the threaded part advances?

VaughnT Posted December 12, 2015 Share Posted December 12, 2015 That looks like it'd be real handy to punch out the screw holes on wall hooks. Also be good for dimpling, raising and veining thin sheet to make leaves and flowers. Not ideal, but certainly a workable solution. Quote Link to comment Share on other sites More sharing options...
Alan Evans Posted December 12, 2015 Share Posted December 12, 2015 Are both of the guide brackets the threaded spindle passes through threaded, or is one clearance? Is it a tapered chuck? Is there a notch in the side of the punch by the chuck mouth to hoik it out with, or is there a grub screw holding it in? Unless it was just made up from bits kicking around, the crank handle implies that the tool was rotated, rather than just for aligning/guiding the facets of the punch. The adjusting wheel is fairly small in diameter and does not give much mechanical advantage as far as the pressing goes. I was wondering if it was a reamer for making/opening holes in something soft like lead or copper. A nut or short length of tube could form a bottom die to support the workpiece and allow the tool to pass through. Possibly for cleaning out tubular fittings? I recently unblocked a calcified drain pipe with a hammer drill and then hammered in and rotated a square steel pin. Alan Quote Link to comment Share on other sites More sharing options...
Daswulf Posted December 12, 2015 Author Share Posted December 12, 2015 Vaughn, not sure it would work fast enough to do what you said before the piece losing heat. Good ideas tho, thank you. Couldn't hit to mount it up and try. Alan, here are some more pictures. I'll post a reply a lil later. As my brother just showed up with some coke for me . Post will dissapear if I wait Quote Link to comment Share on other sites More sharing options...
Daswulf Posted December 12, 2015 Author Share Posted December 12, 2015 Ok, in the first picture the "chuck" doesn't seem to have any visible way to change out the punch and it seems locked in good. It has a pin holding it to the shaft it rotates on that inside of the threaded outer shaft. Picture 2 shows the inner shaft handle that rotates free inside the dial crank of the outer threaded shaft. Pics 3 and 4 are size reference. Quote Link to comment Share on other sites More sharing options...
