|Thread: Substitute for limonene|
Thanks for the professional view, I will try and hunt down some turpentine in our local DIY store and see what happens.
@Steve, everything I have read about support structures suggests that PVA water soluble filament should be used with PLA and associated filaments due to their mutual compatibility and similar melting points. ABS being much hotter to melt is also apparently not very compatible with PVA - they don't stick to each other I believe - that is why HIPS is proposed as the 'soluble' support.
Currently given up on both since I can't make them work with the intricate print I am trying to do....
Many thanks to all for your input and wisdom.
" When being used as a support material, HIPS can be dissolved in d-Limonene, leaving your print free of any markings caused by support removal. "
I am no chemist but I am aware that the two are very similar, hence the search for something that selectively attacks the HIPS.
@ Brian, thanks for the information, I also saw (in a US reference) a suggestion that turpentine could be used - the real stuff, rather than the commonly available substitute.
Thanks for the reference to reprapworld, that may well help!
hoping some of the more chemically minded folk here will be able to point me at an alternative to R or D-limonene which are apparently the liquids for dissolving HIPS (High Impact Poly Styrene) when using it as a support material.
Buying it here in France looks non trivial as is the price. Added to that, the web seems to think it is not very pleasant to work with.
I have printed an ABS model with HIPS support under the impression that it was easy to dissolve with readily available chemicals, but I am so far sadly disappointed..
|Thread: Are there any left?|
Guess you would remember John Hall tools as well -think it was Morgan Arcade but it might have been one of the others around there. A constant source of things in those days as well as their industrial place underneath one of the motorway (?) flyovers. My main source of materials was a model shop on the western outskirts of Cardiff that did ME stuff as well including ST D10 castings.
|Thread: Steam powered RC aircraft|
Try reading "Experimental Flash Steam" (Benson and Raymon), chapter 4 contains a couple of pages and drawings about a flash steam plant built by HH Groves - including a contemporary description (1916). Later in 1936 a set of plans for a complete plant weighing 5oz was published in ME (apparently).
Prof. Chaddock apparently built a replica 'many years' after the original.
|Thread: Anyone recognise this mains connector ?|
Thank you everybody for your input and comments:
@engine builder, @stuart bridger, thanks for confirming its a ceramic connector
@Michael, I cannot believe that you managed to find such a site - geeks of the world unite! (on a side note, we have visited a museum of combs and a museum of the corkscrew down here - the comb one was good, the corkscrew one not really)
@Robert Dobbs, great, thats the one!
@Mike Poole, @Max tolerence, also great, I will follow up
Proof once again that the ME site has a wealth of knowledge waiting to be tapped!
Thanks for the suggestions so far but since I am also based in France, I need a replacement that I can either buy over the web or get directly.
Looks like it isn't very common though...
i bought this little furnace for what I consider to be a bargain 15€ but I don’t know what the connector is...
the furnace was bought in France, apparently of German manufacture and helpfully, the date stamp is missing but I guess its 70s unless anyone knows better.
Pins are 6mm diameter and roughly 20mm apart
Connected it up with a botch job to confit works, need to do so more safely now.
As ever, the aid from fellow model engineers is very welcome. Simon
|Thread: Plan/Design for spanner roll?|
A bit of a late contribution but the following photos show the toolroll that came with one of my classic cars - as the final photo shows, this one was replaced I assume because someone nicked the original....
Heavy canvas, and as far as I can tell, more or less flat pouches. It sits in the boot strapped to the battery cover with two leather straps (not the original ones, I replaced them with something from the dog supplies shop!).
A fold down panel to stop the tools dropping out when rolled up. Integral cord to tie it up (no velcro here!)
All the tools are high quality Bahco, King Dick and the like - sad thing is that I don't think I have ever used them in 27 years of ownership.Mind, for the selection, 121GBP in 1990 was a pretty good deal I think - and it was a genuine manufacturers supply.
Anyway, hope this may help the design process.
Andrew, I too will miss your input and analysis.
|Thread: Another "What is it?"|
Thanks for all of the input, especially Howard’s detailed description. It came from one of our local ‘vide grenier’ car boot sales in southern France so that may also tie in with the low power comments reflecting the popularity of diesel engines here for all forms of transport until recently.
I thought that it was unused until I took the photos and then saw some graunch marks on the knurled knob where someone has gently taken a pair of pliers or the like to it. Not serious but not perfect...
Maybe a tool to pass to my neighbour who has a fine collection of French classics
Sadly, all I get is a nice link to mine.....
Thanks, I found some things from the Panhard club too - but nothing suggesting it was either specific to something nor the 'proper' application fr it
Yes, its mine.....
I have had this tool for some time on the basis that "it will come in useful sometime..."
I have now arrived at the point where its time to move this onto someone who a) knows exactly what it is and b) can use it...
I have advertised it on Homeworkshop in the hopes that someone would see it and decide they knew what it was but no takers.
If anyone can tell me what it is - or even take it off my hands I would be very happy.
I believe it is a pressure sensor for fluids where the lamp under the red cover lights up at pressure "X", whatever that might be. Beautifully made and heavily chromed and looks almost unused - but maybe unused for a good reason!
|Thread: Rejects for Sale.|
Neil, time to 3D print some like these....
|Thread: Result - the 2019 Stevenson Trophy|
Voted.....thanks for the reminder
|Thread: Diamond burrs|
The (slightly tortuous) title says it all I think - I have a couple of sets of these burrs, some sourced from Dremel and clones, others that I bought many (many!) moons ago.
Apart from the obvious glass, ceramics and other super hard stuff, are they any use for softer materials. In this specific case, I am thinking of a tough but not unmachinable steel where a Dremel based grinding action would be much preferable to a simple lathe tool.
|Thread: Changing Broadband|
I am the IT department for my my father who manages to sort most IT related problems on his own without recourse to me. However he has a major problem with his ISP (Talk Talk) which at various times would be better labelled 'Mutter Mutter' or 'Mumble Mumble'. He was migrated from Tiscali, at the time I helped him select them as the most efficient and reliable ISP around...
I now need to find someone similarly reliable and offering decent (not necessarily lightening fast) broadband along with a couple of email addresses and easy setup. Quality is implied in this search, rather than minimising cost, since I will pay for it in time in the end...
No longer living in the UK, I have little idea who might be a good ISP to try - so I throw this open to the forum for your advice please.
|Thread: DraftSight no longer free|
I suggested it in this thread too along with a link.**LINK**
(its the first post today, not sure how to link down to individual post level)
