Wayne and DonG’s Big Adventure….

Waynejitsu had some work done by DonG on his Talon SS. He paid a lot of money for it and when he got his gun back it did not work. I took pity on him and offered to take a look at what was done.

So here we go.

When the gun arrived the first thing I noticed is the bolt and hammer were galling, Rubbing, against the frame. This created a lot of friction, in addition I noticed the bolt took a couple of pounds of pressure to slid on the barrel. All of this friction adds up is not good. It requires a lot more force to move these parts then necessary.

For example the bolt should move like glass on the barrel, not with significant friction. The body of the hammer should not contact the frame ever and should only ride on the delrin bushings.

The hammer is a total misguided mess. It is made of aluminum. The cuts are rough and inaccurate and to make it heavy enough the body was left thicker then it should be which causes friction. The stock hammer while not pretty is perfect for its job. It is heavy and thin and does not cause any problems. In this case the stock hammer should have remained.

The BOLT is an attempt of a knock off of bolts others have made in the past. A look at the workmanship shows some attempts at creating something nice but it has a few short falls. One thing is the hammer slap mod shows a lot of glue remnants and the Oring is coming out of the slot. The waist has 2 diameters which is a sign of careless workmanship. The orings are far to tight and require a significant amount of force to slide on the barrel. It should move smoothly with little force. There are many signs of wear and friction on the bolt and this is because aluminum “Galls” against aluminum and for this reason Airforce uses a Delrin bolt which does not gall or cause significant friction. The bolt is a mess and I reccomend a return to the stock Bolt as well as the stock hammer.

Now for the valve……WTF?

First thing I notice is there is no spanner holes or notches in the valve top under the top hat…curious. I take the valve off and this is what I found.

Now some might be getting all excited to see this thinking is is some kind of regulation device…WRONG….this is nothing more then a chamber which would hold the same PSI as the air in the tank. It would serve no purpose other then to decrease airflow to the valve. The threads are very rough and full of aluminum dust. The OD has a step in it and goes back to the quality of work. This is an ill conceived attempt at regualtion and goes to show how bad information really can make somebody have a bad day.

That’s all for now. Wayne my recommendation is to return to a stock hammer, stock delrin bolt and stock spring retainer bolt.

I will look further at it later.
