Nah! not yet…..
For a while I had been thinking about the ultimate rod cleaning guide, something slightly more bespoke than the normal generic plastic things, the problem is what to build it for? The rifles in this house are not run of the mill, things like Accuracy International’s, Schultz & Larsen, Barnard, Savage, and .303’s (Lets not forget the Krag-Jørgensen) What we do not own are Rem700’s so when someone suggested I build one for a Rem I had a problem, no rifle to test it on. As luck had it some one on the F-B Forum had a Rem700, was happy to test and could supply dimensions and photographs, down side is he was 100 miles away but that is what we have the post office for.
The plan was to build a standard middle section for the Remington, add screw in nose sections sized to the chamber (This one is for a .308 and has an O ring to stop cleaning fluid seeping back into the Action) This gives the user the ability to swap just the front to suit the chamber instead of buying a new guide.
Next thing is keeping the guide in place, the arm that locks into the bolt handle cut out is spring loaded to maintain a constant pressure on the front section and O ring, the arm has a sliding stop behind it that can be fine moved backwards and forwards to fine tune the nose section pressure if needed and stop the spring pinging off when removing the guide.
So far so good. Next part is the rear guide, this is sized to the cleaning rod and is slid onto the rod first, then the patch added and the whole lot pushed together to maintain a constant alignment of the cleaning rod, the rear guide again has an O ring to keep cleaning fluids contained and a port for the cleaning fluid.
Final part was fit a suitable spring. I ended up winding my own as it gave me control over the dimensions and compression rate. It also saved buying half a dozen different springs of varying rates and sizes and testing them for operation.
So is it the Ultimate cleaning rod guide? In a word………NO.
The rear section needs to be a side fit over the guide body, not slide inside it, this allows a greater internal diameter. Also the cleaning port ended up in the wrong place so it needs to be moved back lightly, I will enlarge it at the same time. The locking handle needs tweaking as well so it fits into the bolt handle recess properly. The joys of working on a part for a rifle without having the rifle to hand.
No matter, it has been fun so far and I am sure the design improvements I have in mind will make it work, the original body was machined out of one piece of 6063-T6 aluminium, it would make sense to make it from two separate tubes screwed together and of course it needs anodising when finished.
