Q:

Shiney Thing !!!

Start of new project ,this being a lump of 128x70x30 6082 T6 alloy for my 8 shot rotary mag bullpup. Ive got to put a 14mm hole all the way through this on my tiny lathe for the probe and barrel to line up and a 15mm x 90mm deep hole for the hammer to travel . This all done on an 8″ lathe is going to be scary ! ๐Ÿ˜ฏ

Putting it in a four jaw chuck on a 6mm hold is looking the only way of machining it .Its going to be quite a mass to swing at any speed but il see ๐Ÿ™‚
So as with the last gun this is going to take an absurd amount of time to complete and very likely to drag on for far too long. It may also be a no starter if i cant machine these to holes but arfter spending 4 months finalizing the drawings i realy want to give it a go .So L8ter all …….Much Later hehe ๐Ÿ˜€

On to the next problem , ive got to make a small leaf spring that fits into the 3mm slot and forces the arm up .It dosnt need too much force ,just enough to position the arm into the mag hole for indexing . Im posting on other forums for ideas on how to make one , and thinking of where i can find the material. Open to ideas !

Have an old tape measure or pull start handle from a lawn mower around? Either of these have a nice coil of flat narrow spring steel inside. Might make a suitable donor.

SICK ISN’T IT??!?!? ๐Ÿ˜‰

Can’t wait to see the whole unit, it’s going to look killer!!

Those magazines are off the HOOK!.

Forgot to add ,ive got a BSA Super ten barrel on order for ยฃ65 ish ,should be two weeks ! and im realy happy about it as it will be a good barrel . Ive started on the stock , yet to becide if im going for a bullpup or not .So its just that dam trigger group needed to finish the basic setup ๐Ÿ˜€

Thks “Y” nice to see you back. Small update , finished the mags with a 4mm cut into the side for locking the mag in place. Corrected a hole in the breach ,that was out of round by making it .5mm bigger .This hole houses a pin that locks the mag in place when the indexing arm moves back to the start position.

Wow Buba !

Nice work (and nice work to the ruskies too !) I come back from Vacation and find all kinds of progress, NICE to see !!

Im looking for a .22 cal and 18″ plus long , Chambers want ยฃ90 for a white LW barrel which seams alot as ive still got to get it blued , Leupy said ยฃ59 but a 6 week wait leaves me kicking my feet for awhile. My RFD quoted me ยฃ40 ( which i like ) for a BSA barrel but cant tell me when one will be available as BSA are having trouble keeping up with demand . Gunpower have yet to get back , but there always hard to contact ๐Ÿ™ . Ive got a QB78 if it comes to it il kill the thing for the barrel (hate it anyways) but its not the best barrel for the job.
So that means im looking for other ways of getting one , have to look at a few more web sites ๐Ÿ˜• .

What size barrel are you looking for? You might try http://www.trackofthewolf.com.

Buba,

You also might want to check Chambers. I bet they have a few barrels laying around.

once again buba mate lovely work keep it up

Thanks all ๐Ÿ˜€ , as you know Marc , things will always go wrong but the differance between a good engineer and a bad one is being able to see the mistake and why it happened and not live with it ! . The .1mm run out realy pissed me off , so i broke the set up down and adjusted the rotary table , re set everything up and tried again . Needless to say it took a fear amount of time but that .1 might well of interfered with some thing else. Im not working to extreme tolerances because its a home M/C shop and dont have the tools / machinery for that but youve got to try to keep things as close as possiable to the drawings.
Il try Gunpower for a barrel they sometimes have secondhand one, s cheap , the VCR act has made getting hold of parts difficult. An example : i can buy a white barrel over the net and get it posted to me but i couldnt do that with the cylinder , that had to come through a RFD !!! . I can make a cylinder but couldnt make a good barrel ,wheres the sence in that !!! crazy…..L8r all

You got that right!

I do need to instal a DRO eventually!

As a fellow machinist I hope you appreciate this…. But R.E.S.P.E.C.T as Aretha Franklin would say. That will take a lote of patience and concentration to do!
I really enjoy these pics!!
Just nearly finished my home and so got some time of from the misses to work my machines. Made some trigger parts for my .458! I’ll soon post some pics. And I must agree woth walkonking. If only we all confess to our screwups. This would be a busy forum ๐Ÿ˜†

Regards,

Marc

Buba,

Sound just about right…lol. If only all of us confess to all the shit we screw up before we get one right ๐Ÿ˜€

About the barrel. Have you though about buying one from Gunpower?

Hiding from the Russians with Milly ( my Cat ) in my underground bunker in Norfolk……..Doohh!! …..work continues on the Tv4 copy. Got 3 mags nearly finished , just a notch square to the pellet hole to do . Theres a pin which locks the mag into position with said notch ! ๐Ÿ˜ฏ ……..yeh yeh none of this post makes any sence i know , just look at the pretty pics ๐Ÿ˜€

In total i made 8 mags , one was scraped while turning but i thought id use for setting up , one spun because i got lazy with bolting it down , the belt drive F****D one when it came lose ( my machine wasnt the same as the drawings i used ) Damit and took a chunk out of it , one messed up while i remembered how to work the rotay table and one more to make me strip the rotary table to adjust it so it rotated correctly .:shock:
It was a very fustrating time…!
These As you can see the arm moves the mag round clockwise and at the return of stroke ,it is pushed down under the mag springing up at the finish of cocking into the slot for the next cycle ๐Ÿ˜ฏ

Still looking for something to make a leaf spring to push the arm back up , thats not been easy to solve !. Also at the moment i cant get hold of a barrel unless i want to pay silly money ,so il have to think of another way. Wonder if Piramid air export barrels …hmmm! . So next will be the parts of the trigger group , fun fun …..fun ๐Ÿ˜•
Have ago Jezx , just dont give your address out to the Russians ! hehe
As far as the 4″ table gose , its a real asset , a DRO would be nice but you can do far more with the table.
Take it easy all L8r ๐Ÿ˜€

Wheres my drink ………
