Tom, I have been following your post for weeks now. Amzing talent you have with machining and math. I check your post every day and sometimes twice a day for updates.... Can't wait to see and hear more.
Thanks so much for sharing you skills with us.
Gene

Thanks Gene, I really enjoy this place. Especially the way everyone shares their ideas, work and expertise with nothing asked in return. Well maybe a dialog It could be a while before their is more; I just got called to Federal Court as a Juror which means a 65 mile drive to and from. I'm hoping to get excused........

federal court, hmm be interested in knowing what the charges are. if some one has to go to federal court they did something really bad

You have a good chance of getting excused if you are self-employed.... especially if you have to close down your business to attend court....

Bob

Exactly the case for me. I filled out the "excuse" form and sent it in. Hopefully they will see it my way.

Should I send them your name? This guy Mike would like to go in my place

I remember all the years the compay I worked for got me out of jury duty. Hope it works out that you do not have to participate. Ya folks here on the GTA sure are free with help and advice. I learn so much from the pictures and posts. Like a whole nudder education. Even old coots can still learn...

Good luck and hope to see you back soon.

Progress has been slow mainly due to my shop being busy. I had some time this evening with my kids away on sleep overs and the wife busy with her community obligations.

One shop, one gun and one beer

Sorry for the blurry pictures. For some reason my phone is not focusing correctly, I must have dropped it too many times

Some day I will invest in a real digital camera that can do decent macro.

Stock drilled and reamed for pivot pins and linkage. Bolted down for the contouring of the top side of lever.

Top side done. Ready to flip over

A couple of levers. The sharpie hashed section will be removed in another operation. Yea, I missed a few pictures

Lever installed in rear block.

Rear view. Unfortunately there is a small interference inside the rear block that prevents the lever from closing all the way. It is a minor thing, the pocket in the rear block will need to be milled deeper by ~0.050. No mater how many times you check the model some things are always missed. The lesson is - If you modeler has interference checking, make sure it is turned on!

Next up is the cocking bar and its linkage. Stay tuned!

Tom,
The CNC capability really lets the creativity come thru. It gets better every time!

I Ha friend who was a machinist and showed him your pics from this thread and he was impressed at what you were doing. great work i cant wait till this thing is shooting......dave

Thanks Dave and your friend as well

This part is for Lloyd, made from 7075 AL. We wouldn't want to build a gun from rubbery material........

All kidding aside. I was my intention to make this lever from 400SS or 17-4SS so it could be hardened but I thought I would make a test part or three from the AL to check the geometry. Once the cocking mechanism is completely proven , I will remake make from a more suitable material. Here are a few pictures.

The part in sitting on the vise is the first operation and the part in the soft jaw is the same part flipped over for the second op.

This what is revealed after milling away the excess material

A view of the lever and rear block with the new linkage installed.

Beautiful work!!!

Thanks Bob.

One more link closer

Sorry Lloyd, not 7075

Tom,
I do love linkages. I get to do some of that at work with 4 link systems and it's kind of amazing the ranges of motion and leverages you can get. Beautiful work Tom, and I am sure the gummy aluminum will work just fine, LOL.
Just very, very, nice! I continue to be impressed!

Lloyd

I forgot to mention that the dog bone link is 4130

Not bubble gum

What a wonderful execution. You are a talented man!

Tom she is coming along great. Hope you do not have anymore interuptions..

I am following your thread very closely. Learning something every time you post now. Wish I had some of your talent and knowledge.
Absolutely beautiful craftsmanship.

When I first saw your cocking lever, I wondered how you were going to get enough throw to cock the thing. I think I see how it works now. I still want to see it in action cocking each piston separately.

Very nice work! Keep the updates coming!

When I make another lever for my rifle, I'm going to incorporate an offset handle like you did. I did not think it would be needed but after using my straight lever, I'm sure it would improve the ergonomics.

QVTom · « **Reply #78 on:** June 01, 2012, 02:23:35 PM »

The jury is still out on the ergonomics, It's hard to tell how it will feel until the power plant is in. My handle extends a bit past the receiver so it wasn't completely necessary to offset, mostly I wanted it to look different from the norm and be user friendly as well. In your case, with the extended receiver, I think the offset will be invaluable and look cool to boot!

One thing is for sure, it's hard to beat the break barrel for ergonomics. Side levers still fell a bit unnatural to me . At least its designed for a lefty

QVTom · « **Reply #79 on:** June 17, 2012, 02:34:11 AM »

I've been secretly sneaking some time to work on some parts. I've got some travel for work coming next week and have lot to do to get ready but I really wanted to make some kind of progress before I leave.

So here are some pictures. I've left out all the set-up and op-by-op stuff because I think you guys may be getting a little tired of "more of same". On to the pictures.

This is the cocking bar, pawls and center guide. These parts are made from 7075 AL and will be hard anodized after testing.

A close up view of the parts. The bar has an undercut slot so it can ride on the center support, similar to a 1911 slide and receiver. The pawls will ride on some dowel pins with torsion springs to actuate them.

End View.

This is what it looks like when assembled. I fixed a couple of clearance issues with the handle and rear block, now the handle will cycle thru the full range of motion.

One more of how it looks when the handle is stowed.

The next step will be the pistons and seals. When they are done I will do some fit and motion testing, then take it all apart and have the compression tube, pistons and cocking parts plated. When they return from plating it will be time to add a receiver and test fire!

I'm starting to think that this gun is going to work

and very excited about the cocking system. So far it is operating perfectly.

Tom
