Dial Thumb Screws
|
So I didn't adhere to the old adage of measure twice cut once.? Actually I didn't even measure in one instance.
I had some 1/2" bar left over from another project I did for a guy, which was some brass electrical connectors for a 1929 Chrysler.? Little bitty knit picky bits. With extra brass, I decided i'm done with the little set screws on the dials and thought I'd make a thumb screw for the cross slide and compound.? I measured what a good size would be for the cross slide and made 2 of them.? I didn't even look and measure if it would work on the compound, since they are similar. The cross slide screw came out great and when I put on the thumb screw on the compound the large OD thumb portion contacts the OEM fastener head that holds the end cap for the thrust bearing.? A sample pic is attached. It's not my part but it is the same screw driver head as mine. I'm thinking? of a couple options. 1)? Trim the length of the thumb screw and maybe even the thickness of the thumb portion so that it will sit low enough to get by the raised screw head of the fastener holding the bearing end plate on the compound.? 2)? Take the bearing plate off and counterbore it so that the fastener head sits flush.? The chrome is gone, it is now powder coated. I'm pretty sure #1 will work.? I need to get back out there and measure.? Thinking about this i may actually trim the length of the cross slide thumb screw to get it closer to the dial.? It sits proud a few threads. Just curious what you guys thought or to see what you guys had or if you had another option.? Thanks, Jody |

开云体育I think so too.? I may have to make it a little more low profile than the first one and make sure I get the threaded length right.Although if I ever go to a larger dial, I will to make fasteners flush on the end bearing plate. Jody -------- Original message --------

Option 1 sounds the most logical choice

Hi Jodi, This is my solution. As "buffer" I use, between the spindle and the screw, a small piece of copper to prevent damage.

When i installed my bigger dials I made my own thumb screws, i happen to have some stainless 3/8 dia. rod the screw i believe is 8/32 instead of knurling i used the tool bit and cut lines in the head of the screw. Don't forget to put a piece of brass under the screw used a bit of a? brazing rod for that GP

开云体育Thanks guys for the advice.? My screws are brass so should not mark the screw.After doing some measuring last night on the compound, the dome bolt head holding the bearing end plate on, really limits the size of your thumb screw. The thumb screw will roughly need to be .250 OD and .150 thick. I'm almost out of brass stock, so I might just countersunk the holes in the end plate and put some countersunk socket head bolts in there.? Then use the thumb screw I have made already.? I will still probably need to turn the OD on the new thumbscrew down some from the 0.500 it is now. I would like to make some bigger dials but don't have an indexer or number stamps.? I guess I could rig something on the lathe.? But for now I have other projects I'm ready to start instead. Thanks for the inputs, Jody -------- Original message --------
