March is almost over, and what a March is has been.
We continued our series of write ups on Spud Guns. This one focused on building out the combustion chamber. Once the PVC fittings are put together and the glue has dried there is still some work in ensuring electrical connections can be made to the igniter and the fan. We detail all of that work in the write up below.
The Humble Spud Gun: Combustion Chamber
Sighting in the VZ-58 has been a small project in its own right. Discovering tools that are needed and weaknesses in the build. We took a hard look at the trigger, being that it really was not working for us. We took a look at our options, tried a few things and came up with a solution that got us a better trigger. See the detail here’s :
Last week we had indicated there would be an update to the Powder Burn Rate chart to include SMP 764 and 6.5 Staball powder. We have not release the update yet, as we want to check the approximate burn rate of SMP 764 against SMP 765. Be patient with us and we’ll get this update out as soon as possible.
I was able to track down some 7.62×39 ammo at a local pawn shop. So we will continue working on sighting in the VZ-58 this week. Hopefully we will have that finished off. I also plan on doing some bullet casting, and try my hand at epoxy coating. Expect some follow up write ups on both of those topics. We will also be working on the Spud gun, but we are waiting on some components to arrive, there may not be an update on that this week.
With everyone stuck indoors what have you been up to? Have you worn out your presses yet? Run out of components? Sold the kids to buy more? It been tough for a lot of us, hopefully we are through the worse of it. Let us know what you’ve been up to over at Facebook.
As always if you have questions, comments or concerns shoot me an email at jayandrew338@gmail.com. I’ve heard from a few of you and I have really appreciated the feed back and conversation. Stay safe out there.
Thanks,
The Ballistic Assistant
