Alasdair Ryan Posted November 20, 2011 Posted November 20, 2011 (edited) So who wants to build a lego cnc machine? A lath might be better but i dont know if anyone has built one out of lego,i cant find one on youtube. It will set me back about £40-£50 to cast longer rams in liquid plastic, but i am not sure if this would be strong enough. Edited November 20, 2011 by Alasdair Ryan Quote
allanp Posted November 20, 2011 Author Posted November 20, 2011 (edited) The next stage would be to for someone to try making one and then if thay work, and if alot of people would want one the start selling them,easy as that . Yeah, easy peasy! Awesome render! I do want to say that this new cylinder is significantly shorter than 2 large pneumatic cylinders put together when they are fully extended. Other than that i think it looks good.tim Thanks. Remember the current one has a stroke of only about 3.5, so this one actually has a stroke of slightly more than 2 large pneumatic cylinders put together. why not make the cross axle and the pinhole 3 units wide (instead of your 1 and lego's 2 unit wide) and possibly have the center unit be hollow for easier build? and change your 7.5 unit length difference to a whole number? anyone think this is a good idea? The reason for not making it 3 studs wide is because it would take up unnecessary space. You can always add bushes either side to make it functionally wider. I figure making the base only 1 stud wide make it more versatile. The reason for making it 7.5 in lenght was because retracted the ram is 11 studs in total which is a whole number in length. To make it 7 or 8 would either not use the full space available or make the retracted length not a whole number in length. Could we persuade a third party company to make these pnuematics if we specify exactly what we want?Tim That's a possibility with enough money, but i'de rather pursuade TLG to make them as a proper part for future sets. As part if that I wonder if somebody would be willing to make an Ldraw version so that we could demontrate their usefulness in actual lego models at the sort of size and piece count they like to make official lego sets, both small and large. I imagine many places where these would be great, like a small forklift truck or skip lorry or container truck or crane or larger excavators or front end loaders or back hoes and so on. C'mon technic team I know you're reading this Edited November 20, 2011 by allanp Quote
Alasdair Ryan Posted November 20, 2011 Posted November 20, 2011 I am away to try biulding a small ram out of plastic,i will report back here in about an hour and a half or so. Wish me luck. Quote

Alasdair Ryan Posted November 20, 2011 Posted November 20, 2011 Update: I need to make a rubber seal i think its leaking through the top. Quote
DLuders Posted November 20, 2011 Posted November 20, 2011 @ Alasdair Ryan: You can go to your local store and get some Silicone Sealant to make your custom-fitted gasket seal. Quote
Alasdair Ryan Posted November 20, 2011 Posted November 20, 2011 I happen to thave a rubber mold already so i am just going to cut a bit of that a see what happens. Quote

Alasdair Ryan Posted November 20, 2011 Posted November 20, 2011 (edited) Thanks Allan We are doomed! does not workwell at least i made another mess on my bedroom floor ,I think it is down to the size of plastic tube and rod i am using thats all i had ,Photo bucket is broken down as well ( it is not loading my pic's),i tryed rubber bands but it was not working ether.

allanp Posted November 22, 2011 Author Posted November 22, 2011 Sorry Alasdair but I can't seem to download your picture from the link. Quote
Alasdair Ryan Posted November 22, 2011 Posted November 22, 2011 (edited) Here you go Allan: As you can see i started painting it blood red. Edited November 22, 2011 by Alasdair Ryan Quote
timslegos Posted November 22, 2011 Posted November 22, 2011 Looks good so far. Why iS it painted in blood?! Also could you take a more focused photo? Quote
Alasdair Ryan Posted November 22, 2011 Posted November 22, 2011 Can you not guess why it is painted in bood red. Quote
allanp Posted November 22, 2011 Author Posted November 22, 2011 (edited) This is an appeal for AFOLs in need. Poor Alasdair has slipped with a knife whilst trying to make a longer pneumatic and is bleeding over everything. Just one e-mail to Lego demanding longer pneumatics can make a difference, so please get typing, or type whatever you can, and help end this madness. Give a crazy scotsman a knife, and he will stab himself, give a crazy scotsman a longer pneumatic, and he'll still have fingers to build lego with, for a whole life time. So please, start typing today. Thankyou. Edited November 22, 2011 by allanp Quote
allanp Posted November 22, 2011 Author Posted November 22, 2011 Just had a thought. Brickarms make custom Lego parts to a very high quality right? Maybe they could help us. Are there any other companies like them? Quote
davidmull Posted November 22, 2011 Posted November 22, 2011 Here you go Allan: As you can see i started painting it blood red. Sorry to hear about ur finger but that ram looks way too long to me! Where would we put something that long lol, if we got twice the length of the existing ram I'd be happy. Quote
Alasdair Ryan Posted November 22, 2011 Posted November 22, 2011 (edited) Don't panic i still got 9 fingers,i just made it any old size,if it worked i would of built a forklift. Edited November 22, 2011 by Alasdair Ryan Quote
roamingstop Posted November 22, 2011 Posted November 22, 2011 Don't panic i still got 9 fingers... Well if any are missing take a short trip to Callanais and asks the stones to produce one for you. Might take a while for the next full moon to arrive, but the bleeding should have stopped by then. My concern with such a small thin ram (which would look great) is the resilence over a long time of use. However the idea to talk with Brickarms is probably worthwhile. Alternatively ME Models who recently did the new Lego Train Track also have custom made pieces which look pretty fantastic. Having a rapid prototype assembled version would typically cost around 2000-3000 Euro for a batch of 10 prototypes. You would need to plan how to assemble them; and also machine parts separetely but it should be doable. I guess Brickarms have a much tighter packaging volume, and a good customer base, to make these things work. Anyhow lets hope the bleeding stops before reaching Stornoway hospital. Quote

No none are missing it was only a small cut to the top nothing to worry about. Quote

aposaric Posted November 23, 2011 Posted November 23, 2011 2000-3000 euros sounds a lot to me. What about Hi-technic to make some? 2000-3000 euros sounds really cheap to me for prototyping. If you look at the price of a LEGO mould, which is from 200.000 - 500.000 euros per peace ( depends on complexity of a peace ). I really hope there will be some longer version of pneumatics, because I am totally hooked on them Quote
roamingstop Posted November 23, 2011 Posted November 23, 2011 2000-3000 euros sounds a lot to me. I based it upon prices which we use at work for similar sized plastic prototypes. Sometimes it is more; sometimes less. But it is for prototypes, and not complete moulded pieces. Hence quality is ok, but it is not robust for play. A full blown mould with injection plastic is likely to be much much more. Quote
allanp Posted November 24, 2011 Author Posted November 24, 2011 This is why I think we need to talk to brickarms as they do have molds made and their parts look like they are on a par with Lego almost. However they would also need to produce the longer steel shaft. The seals and so on may be recyclable from standard pneumatics. All this is dependent on weather or not we actually need prototypes. I'de much rather have Lego produce them. Quote

allanp Posted November 24, 2011 Author Posted November 24, 2011 It is done! Well I posted something somewhere anyway Quote
