Thanks. Thanks fellas for the complements. It's nice to have one's work scrutenised buy the people in the know and have it given the thumbs up.. :D Roo, at this point it's not looking like i'll build any more. My employer has very generously allowed me to use the CNC machinery at work free of...

Update! G'day gentlemen.. Well over the last few evenings i've managed to get the bolts started. The turning operations were completed in my lathe at home and at a much more leisurely pace than i would be at work. I've been going over the drawings this week in preperation for the machining...

Update! G'day Fellas.. Well its been a few weeks since i had some time on the machine, but i took my RDO today and managed to get the CNC part of receiver machining finished. The pic shows the general setup for maching the receiver ring and lug rebates. The same precision bar and bushes...

I would have to agree with Jackie here. Yes you can use the spider chuck to set the stock to run true but unless the bearing is exactly inline with the headstock bearing and then the both of them are inline with the bedways it's not running axialy true. This is a common misconception/problem...

G'day Fellas.. Looking at building a new front rest as the one i have is a pretty basic unit i built about 10 years ago and with the old bags i have is now holding me back competition wise.. Realy interested in a coaxial front rest. Anyone know how the mechanisim works? I've read a few...

On my initial designs i had Piccatini rail milled into the top of the receiver for scope mounts just as you say, square and in perfect alignment with the action. However when i looked at what the two rifles were going to be used for, one for 500-1000 yard target and the other for 100-200...

Metric?? Thanks for that John.. For the benifit of those metricly chalenged folks i'll go back and add the inch conversions in the posts later tonight.. :D Cheers Leeroy

More Progress. The receiver blanks were placed in the rotary axis of the CNC mill. This means that it can be rotated very precisly to any angle desired accurate to 1000th of a degree. It was then roughed down to 0.1mm (4 thow) oversize on all 6 sides with a 40 dia insert cutter and then...

Update! G'day all Well some of you may have read about my plans to build my own action (Cuz I’m too damn cheep to buy a ready made one :D). So I thought I’d post a log of my progress as I go along. So where to begin... Well I won't bore you with the 3 odd months of evenings I spent in front...

G'day guys.. Sorry about that.. I didn't realise that you needed to sign on to AHN to ready my Build log thread. Unfortunatly thats the rules of that forum, one must have an ISP e-mail account which helps to weed out people like the Clown above.. At any rate in the interests of national...

Well Rad clearly the action won't be real good if it's built by a "Brainless Ape" like me.. So i would sudgest someone as obviously intelegent as your self shouldn't even bother reading about it. OOH OOH OOH AAH AAH AAH.. WANKER! Leeroy

Action Build Log Updated. (Large pic content) G'day Fellas. Some you you will remember mid last year i was asking questions about building my own action from scratch. Well after 6 odd months of research, drawing, several false starts and a severe shortage of "Spare Time" work has finialy...

Wire EDM G'day All Without a doubt wire EDM is the most accurate and arguably the best way to cut raceways. Especialy if they are to be cut after heat treatment. Trouble is like Tony says that it's DAMM EXPENCIVE. At least here in Australia it is.. The cheepest quote i could get to cut...

Barel Blanks G'day Ron As far as i know MADDCO Barrels here in Australia flute the barrell after it has been drilled, reamed, rifled and stress relieved, but before the final lapping. Cutting the flutes can cause the bore dia to grow slightly, and can also cause the barrel to warp slightly...

CZ Pitch G'day Dwight The pitch on my CZ 452 (BRNO Model 2) is 1.25mm. This equates to 20.32 TPI. You could re-chase it to 20.5 TPI but you would have to open out the Dia quite a bit. The pitch error is arround .0004 per pitch so for 20 pitches would be 8 thow. Just out of interest why...

Design.. Ok Gentlemen after much reading/studying pictures over at Homegunsmith.com and having a "Play" with a few rifles at the LGS, i have decided on a basic design. The action will be a 3 lug "Fat Bolt" design. Receiver will be a flat bottom rectangular shape with built in scope rails...

Problems! G'day all. Well last night i finialy got arround to calling my mate who has access to the EDM machine and guess bloody what?? He dosn't work there anymore!! And his new work dosn't have an EDM machine!:( BUGGER!! So today i started calling arround all the tool and die companies in...

Thanks For all the great feed back here gentlemen.. I have been going over in my head (As i often do) the machining sequence. Ie what machines to do what parts of the action, what setup to use etc.. I have most of it sorted out, just one thing has me stumped and i mentioned it in my original...

Still deciding.. G'day Peter At this stage i plan to braze or silver solder the bolt hande on ALA remington style. As stated by jackie it could just as easily be tig welded on. I am very capable at both processes so the design of the bolt will infleuence my decision. Tig welding if done...

Hardness Peter, if you think i should keep to less than 42 HRC then thats what i'll do. I would like to get at least 3-4 points difference in Hardness between bolt and receiver so will probably go for 39 HRC for the receiver and 43 HRC for the bolt. Or should i go the other way arround and...
