3D Reproduction of Items

Hi - not really a 4x4 tech Q but Tech none the less...

I'm after the services of a 3D reproduction machine, one that can work in timber preferablly... its for a rifle stock that has snapped. I have the original unit but would like an identical (or near enough) new one reproduced for cheaper than a custom one can be professionally made. Professional gunsmiths charge hundreds for this service which hardley seems reasonable for the atic dweler .22 i own (family hand me down)

I'm open to other materials such as alloy, hard plastic/polyproplyene/polycarbonate type of substance etc just looking for relative lightness and ultimately strength...

Can anyone help?? CNC'ers, lathe workers, IT Guru's etc...

(mods if this needs to be moved please do so - sorry :cry: )

i happen to know of a guy making fibreglass/resin ones for sporting use (very ergonomic)... PM me if you'd like his info.

you need to find an old toolmaker with a machine called a pantograph. it is used to copy a part and reproduce it. to cnc it you will need it modeled, this is quite time consuming, then pay for cnc machine time $$$.
heaps of tool rooms are quiet these days, try find a toolmaker with an intrest in firearms and you'll be set.

Supply the timber I'll consider making one for you, depending on the time frame you need it made.

Surely there would be a few toolmakers down in Brisbane, also could try the carpentry groups for the retirees etc, some fine workmanship to be had in there.

Why not give it a go yourself?

Select a nice piece of mallee root (very dense fine grain) get it roughed out, and take to it with a spokeshave to get the desired result. The rest of the attatchments to the stock could be milled in by any machine shop. You should already have the rough measurements from the broken parts of the old stock.

Unique one off, not bad to look at, and a sense of achievement to boot in the making of it. It then really is YOURS :armsup:

I can 3D laser scan it for you :cool: but for something a one of like this the other suggestions are probably more practical.

If your stock is able to be held together in it's original shape to use as a pattern, then there's a fair chance it could be sand cast in Aluminium.

You can CNC it, but you'd need someone with either a CNC touch probe or CMM to probe up the original to recreate the surface shape. This will make a gunsmiths price appear very reasonable.

You're probably better finding someone skilled and retired who can spend the hours needed to do it by hand.

I was thinking this as well.

I'm not sure if a spokeshave is the same thing I'm thinking of 2 handles on the side and a plane blade in the middle but get a vise and measure up the orginal then plane away and measure heaps when your coming close to the same size, like every time you make a pass.

Though I was just thinking maybe you should do a good search around because you might find the stock to buy then just fit it up yourself.

That is a spokeshave....

Thanks All

After much research (and shock i might add at the prices quoted for custom/reproduction of unique piece stock making) i have decided to give it a go myself, and sourced a piece of hardwood yesterday, not sure what sort exactly but hey it'll do.

I'm thinking of using a saber saw to get the rough shape (used like a carving knife) in the first instance, then a rasp and file/sanding etc down to a fine sand and wax or oil coating. The spokeshave looks good for most of it however there are a lot of tight curves and the channel for the barrel to sit in will be the most difficult part i think including the relief/void for the trigger mech to pass through...

But hey - nothing ventured nothgin gained. :?

Also though of potentially using acrilyc like a hard block of perspex typoe material, this would be easier to reproduce in 3D and probablly more machining tools available for that sort of thing? Like in toy or light engineering manufacturing...

If you want to use plastic, Delrin/Acetyl is probably the best option.

Exactly what I was thinking of.

Also used in wooden boat building, can be a handy tool to have at times too :)

You use the spokeshave to get real close to the shape your after treat it like a normal wood plane if you've ever used a wood plane... maybe at school or work? also keep it's blade really Sharp

Also make sure you are going with the grain and not against it or you'll rip chunks out of the surface of the wood real important that.

also try to not have any knots in the wood as again knots will cause problems when planing over or around generally it just snaps the wood or breaks tools.

If you just spend a good amount of time working out what you want and aim towards that slowly and carefully you'll get there without trouble, unlike metal if you stuff up you can't replace wood and redo it.

Should come out great, good luck.

I don't mean to be rude but if you guys had a better idea of how much time goes into making a one off item that is not run of the mill then you might not actually be shocked at the price. Figure in the hours of working it out in the first place, then measuring, then measuring all through the process and the time actually fabricating you might not be so shocked at the prices quoted.

DIY is always going to be a far better option price wise if you can have a crack yourself.

Well it looks like I may not be getting around to my usual cash jobs as I don't have a tow vehicle for work.

If you would like a new rifle stock made to the same design you broke, feel free to PM me, I have a fair bit of spare time up my sleeves for a while.

what brand of rifle is it?

Thanks All...

fester2au - No offence taken mate, I do understand the time taken for a custom item, and the justifiable cost. Its just the cost isn't justifiable/warranted on this particular item. It is like 2-5 times the value of the item even if it was in good condition... which unfortunately it is not.

Thanks for the offer clm434, i think i'll give it a try first, as there is no rush to it. See how i go :lol: could end up call in your services in the long run anyway...

smiley - it is a Belgium made 1909-39 Pieper Bayard, .22 Semi automatic single shot (or half auto).... quite a unique action. Takes .22 long or short cartridges and i'm told even a low power .22 round for very short range small game shooting in confined spaces. The bolt handle does not sit off the one side but rather is a pull back design on the back end of the barrel. For the first shot you pull back the springloaded bolt action, chamber a round, press a release switch on the LHS near the chamber and the bolt action flies forward securing the round in the chamber. You then fire the shot; the action flies rearward, self ejecting the casing and locking the bolt in the rearward open position. Chamber another round, hit the switch, aim and fire. Essentially you don't need to remove your trigger hand from the stock or move too much from the firing position meaning quicker succesion of rapid fire, better grouping as the weapon isn't being moved too far from the original firing position.

It was a hand me down from my grandfather who used to use it for rat shooting in the avery. Small, lightweight, quick and easy to use especially in the dark.

Thanks for all the replies guys.

hope that lil semi of yours is registered or has a nice big plug weld in the barrel, try calling a few old smiths they may have a spare stock lireing around the other option is to get on the US forums ans they have plenty and you might get a stock for it cheap.

You should find it pretty easy to do yourself with a fairly basic set of tools, an eye for detail and some common sense.

Also found the following for a bit of info on your rifle, may or may not help you to track down another genuine stock.
