An in process video of boring out the I.D. for the piece of tubing that makes up the wrench body.
We usually get a few inquiries a week about when we are going to start making wrenches for the SR25 series of URX rails. Well we're happy to announce that we've been spending the last few weeks selecting materials and finalizing our design. We started cutting the test parts today and hope to have the finished product up on the site within the next couple weeks.
After making a soft-jaw fixture to hold the partially finished barrel nuts after turning, I was able to get the initial run on them complete.
Bringing the tool steel URX Barrel nuts closer to production. Running some samples to ensure all the programming to dead one to get precise clamp load on the barrel to align it for optimal accuracy.
Programming the tool paths for OP1 on the lathe for the new URX barrel nuts.
The next batch of URX wrenches are done being machined. Now they are off to heat treat and black oxide before they'll be listed for sale.
More wrenches are coming off the mill. You can see these ones have been roughed in during the first op. More to follow!
For those of you that own rifles with the URX series of rails know what a pain it is to either send you upper into a smith to have it worked on or fork out the dough for a wrench to do it yourself. Within the next few weeks, we'll have something available at a reasonable price to change that.
The sample came back from the heat treat after getting hardened to 35-40 RC, then got coated in black oxide.
After test fitting the wrench on a barrel nut, it was confirmed that there wasn't any measurable shift in dimensions from the heat treated. Now it's time to fire up the mill and start cranking these puppies out.
Machined a sample wrench today to re-check the geometry of my model. It's been a little while since I've made some of these, so it's always good to give everything a quick double check before you do a production run.
d.wilson mfg works on interesting projects from time to time, so this is the place we'll share some of them.
