Not much posting or working in the shop this weekend. Everyone at gun lab.net is SICK. Massive head aches,body aches, miserable coughs, just sick. Work and everything else just caught up with us. I hope to spend time cleaning up my back up hard drive if I can focus on the screen for any length of time. Other then that I am going back to bed.

Took Sunday off to relax and enjoy life. One of the thinks we did was go to a local gun show. Keep in mind that I generally go to only one show a year and that is the SAR show in December so I have not been to a local show in a number of years.

This is the result of my time at the show.

First is OMG the price to get in. 8.00 to park and 16.00 per person to get in the gate.That is a total of 40.00 to walk in.

Second, as I walk through the two buildings and two big tents I noted the following items.

Beef jerky in a multi table event. There were  5 tables selling it. jewelry, posters, gun cases, hats, knives and tee shirts took up another large portion of the tables. If you were looking for AR-15 stuff that was over half of the actual gun tables. There was 3 large areas selling ammo. The rest of the show was of really over priced toys. There was actually a guy selling a 22 cal mp44 clone for 200.00 over retail at the stores. I saw a number of tables selling really expensive old Saturday night specials. When did this type of pistols become worth 4 to 6 hundred dollars. I looked at 6 different tables selling 22 and 32 rim fire Remington rolling block rifles and the cheapest one was 600.00. It was also relic status.

I left the show a little disenchanted. I did get a firing pin for an AR, a set of cheap fold down sights also for an AR,  5 flat springs and a box of 25acp.

Really don’t see a reason to go back for another local show.

I have a ton of projects to work on in the shop. Everything is behind schedule. I worked over 80 hours last week in my primary business and am exhausted. So today I am not doing anything work related. Gun show, movie and diner with my wife. Have a great day everyone.

We have had a few problems with the ejector on the VG1-5. The initial design was for a sheet metal type of ejector. The first ones were made in general purpose sheet steel. They bent with in a few rounds being fired. The second ones were also general purpose sheet steel that were case hardened. These lasted for a few hundred rounds then they also bent. The third model was 4130 sheet steel that was hardened through out. This lead to welding problems and we would have had to do a total redesign to allow for riveting. The solution was to machine a thicker piece of 1018 and case hardened just the end of it. This allowed use to weld it with out grinding it down and still allowed the ejector to take the shock that was necessary to eject the cartridge.

This is the master cam simulation of the machining process.

This video is the actual process of machining the ejector.

This is what the final machined ejector looks like.

Prior to welding in it will have to be heat treated. The initial one that has been make in installed has fire a number of rounds with no signs of bending.
