[...]]]> Another typical weekend here at Gun Lab. As with all weekends a certain amount of maintenance has to be completed. Saturday morning was spent doing some design work in solid works for a new piece of equipment that we are building to make fluted barrel chambers (more on that a little later in the week). I rebuild a friends AR-15. In this case it was a barrel change with new gas block and a very nicely design front hand guard and barrel nut. A write up of those components will be shortly as well. I really like the fit and feel of this  equipment. Enough in fact that I am ordering on for myself. After the rebuild I did a test fire of the weapon in my test firing tube. This is a basic testing tube for function and reliability. I made the tube out a section of heavy wall steel pipe then filled it with sand and to reduce the noise level I added a series of small tires in the inlet and then caped it with a rubber end piece. It works well and reduces the noise level so there is no problem with the neighbors.

IMG_2408_SThere is however one small glitch. That is unburnt powder will build up in the tires. This can cause a bit of excitement at about ever 50 or 60 round when all that powder ignites. This is a video that was taken while I was test firing the AR.

I will post this video as soon as possible. The video that was taken was done on a phone and when sent to me was of such low quality that it is not usable. Post was made off a phone video.

I installed the air dryer for the shop air system. This is it as delivered.

IMG_2407_sIt was a basic hook up, just needed the hoses made up and power run to it. A quick shot of the plumbing.

IMG_2406_sThe last task completed this weekend was finally finishing the lights and power in the fab shop. A couple of pictures of that.

A couple of pictures at night with the lights on to give you an idea of what it looks like.

IMG_2414_s Everyone say that it is to be used as a beacon for the international space station when all the lights are on.

Hope you enjoyed the updates.
