How long ago were these for sale Shamu? I want one!
I have also seen an older cast metal single shot platform that fitted up inside the mag well and latched on the mag catch. I shoulda bought it just because it was old and unique. I have never seen another one.

Okay. This is what I have done so far. All I have left to do is drill the hole out all the way. I drilled out the center of the bolt head the same diameter as an old Phillips Head screwdriver I "had". Left a 1/8" gap on both ends and then welded it solid. Ground the welds flat and started to drill the first hole. Took a No4 extractor and did horrible things to it with a Dremel tool. Contoured the extractor to slightly resemble the .22 extractor. Fitted the .22 tube,shoved a .22 in the chamber,eased the bolt forward until it stopped against the bullet,and then pulled the bolt back. Bullet came out and slid into the back of the magazine. Easy Peasy Lemon Squeezy...

That look's like it's coming together nicely. Seeing all your hard work keeps reminding me that I have an old lathe in bit's. And that I really need to find a place for it and set it up!

It is complete. The firing pin works as does the extractor. Not too shabby for homegrown... ![]() ![]() ![]()

WELL DONE.
The striker protrusion looks a little excessive, but hey, if it works.... I see that you used a #3 bolt head? I saw one on Egay recently, listed with a buy it now price of $150.. It sold.

Thank you. The bolt head had a crack around the firing pin hole. I have two extra #3 bolt heads just in case. The firing pin protrusion is a little excessive to me as well but,any shorter and it won't fire. I made three of them and this is the best one of the bunch. I am extremely proud of what I did. I want to go to the range tomorrow but it has been raining all day and it is supposed to continue until tomorrow night.

looking forward to the range report. Regarding the firing pin; does it have a shoulder on it or is it straight? just thinking that you don't want it falling out when carrying the rifle. I totally understand that this is probably your "Mk1" trial firing pin and bolt head, and it's looking good. Test it and let us know how you get on. |

It has a shoulder on it. Fitting that into the bolt head was the hardest part of the whole project. I will make a Mk2 and Mk3 version in time.
If anyone might be inclined to try this,I found a very simple solution to drilling out a firing pin hole. The bolt head is hardened steel. I got the bolt head orange/red hot. Drilled out the center until I made a 1/4" hole. Took a 1/4" rod of cold rolled steel and cut a 1/16" channel down the length of it. Chamfered both ends of the bolt head,cut the 1/4" rod 3/8" shorter than the bolt but centering it inside the bolt. You are going to cut the striker off of the firing pin leaving the notched shoulder. Flatten and smooth that out. That is going to be the new firing pin striker. Screw that back into the bolt and look inside to see where the orientation of the new striker face is. Take the rod inside the bolt head and turn it until the notch you cut is orientated to the new striker face. Weld one end of the bolt head. Grind the weld flat and rough sand it. Turn the bolt over and before you weld the other side take a 1/16"drill bit and drill out the notch you cut in the rod until you have penetrated through the weld. Weld the other side,grind flat and rough sand. Repeat the drilling process as before. That will allow the firing pin hole to be predrilled technically. The bolt face is going to be resurfaced until it is just touching the chamber face.

When I hand fabricate a small part, it often takes three attempts. The first attempt usually fits and works in a fashion, but needs improvement. The second is better but could be tweaked a bit. The third is usually spot on and I am happy. However, sometimes it takes four or five attempts as quite often, the small part that I am working on escapes, falls on the floor and bounces. It ends up in some dark dusty cobweb and sawdust corner under my bench only to be found years later! I find it hiding out with Jesus clips and springs. A Jesus clip is one of those pesky little circlips that I carefully pry off and, POINK!, it launches itself across the workshop with me exclaiming the Lord's name. A Jesus spring is one that you discover is under compression when you remove the cover or part to get at it. The FN SLR recoil spring comes to mind. |

The bolt head in these photos are my third attempt. The first prototype was a mitigated disaster. I broke a 1/4" drill bit off in the second one after it went sideways. It was a fun learning experience to say the least...

Now I've looked closer at the photos I can see the difference in diameter of the pin. I think you'll have fun shooting it as a .22

I have a box of .22 without the powder. Perfect for the 20 yard length of my patio at my apartment complex. I took three adjusting shots. I have a palm tree stump in front of a 12"thick brick wall. It will shoot.
