Friday and I am catching up on the small jobs whilst waiting for some tool steel to arrive and an early job for the day was this Saiga 12 which is best explained with some pictures over a cup of coffee.
This was the gas piston connection to the bolt carrier on a Saiga 12 that was wobbling badly. Saiga simply screw the gas piston in and then stake it and it is never ideal.
The stakes are clearly visible in this image you can see how much thread is hanging out of the end of the carrier.
First job is drill the stakes out and unscrew the piston, everything is then tidied up and I use a very high temperature adhesive to bond the piston to carrier which is screwed in until tight. Wait 24 hours for the adhesive to set. Now at this point I have to say I am always slightly wary of this as everything needs to be fairly well aligned however this is an accepted modification so on with the job.
Drill through with a 4,2mm drill and add a countersink to either end. The holes where I had drilled out the stakes lined up perfectly proving attention to detail always pays dividends.
Then it is just a matter of machining a pin to suit with a suitable countersunk head at one end. I always go for a tight fit and check this on the machine before the pin is removed as it is always easier to take another fine cut if required.
With fit confirmed the pin is pushed into place and the ends peened over.
The final job is to file the ends of the pin flush with a light emery to complete and the job is done and I defy you to spot where the pin is 🙂
Well that is my coffee finished and another couple of jobs booked in so I had better make a start on the next job which involves a Ruger Precision Rifle.
I have had a few enquiries of recent for a rear bag rider for the Ruger Precision Rifle so here it is as a prototype fitted to a customer rifle. This rider has a 23,4mm tube suspended from a rear plate and if it looks to be sloping up it is! The customer asked for a 10 degree angle on the rider however I opted for 2.5 degrees to keep things low. The idea of the slope is by moving the rifle forwards and back subtle changes can be made to the elevation without excessive bag squeezing.
The finished product will be anodised in black and available with a spacer to give either zero or 2.5 degree slope if requested. I will also offer it with a 20,0mm tube as an alternative so you size it to your own make of rear bag.
The bag rider incorporates the original Ruger fixings so the butt can be canted as with the original and will be made in a limited run so if you are interested or have any questions or comments please let me know.
I have had a few people asking for Rear Bag Riders for the DTA systems so here they are. These are designed to stack with the original DTA spacers and the bag rider tube is removable.
Material is 6082 T6 aluminium, vapour honed and type 3 hard anodised to full military specification. The finish is a satin black with the edges nicely blended to remove snag points, the rider tube itself is attached with an A4 stainless cap head. They should give years of service in any environment. I will be adding them to the SHED Shop very shortly.
Ok, I know there is no such word but I bet GW will have used it at some point so here it is, some laserfication. Today was the start of the graphics application and this is one of the Model 75 tubes being laser etched, the video was taken with a mobile phone so is a bit shaky however it does give an idea of how the process is performed. What you cannot see is the huge power source or the trunking containing the laser itself or the servo controlled mirrors that control the actual positioning of the laser on the surface. This is type 3 hard anodised aluminium which is noticeably harder to laser etch than the normal decorative anodising however it does look good and is certainly more durable.
