Brian Lambert Posted November 21, 2008 Share Posted November 21, 2008 One mm is very small, but "model fixings" do some nuts and bolts.Brian Quote Link to comment Share on other sites More sharing options...
Ernie Posted November 21, 2008 Author Share Posted November 21, 2008 Hi Rusper, Boy, that was quick, and thanks...I've tried them, but they don't do anything small enough I'm trying to make a dummy scale le rhone rotary engine, and the small nuts and bolts do make it look authenticernie Quote Link to comment Share on other sites More sharing options...
Brian Parker Posted November 21, 2008 Share Posted November 21, 2008 Chronos (www.chronos.ltd.uk) do 2BA…12BA hex bolts. Not metric but the 12BA should suit your needs. Quote Link to comment Share on other sites More sharing options...
Brian Lambert Posted November 21, 2008 Share Posted November 21, 2008 These people do nuts down to 1mm but hex head screws only down to 2mm.Brian Quote Link to comment Share on other sites More sharing options...
richard cohen Posted November 21, 2008 Share Posted November 21, 2008 Ernie, maybe its coz i am tight but rather than buy new bolts, if its only for looks rather than actually fixing anything i use the internals from old watches/dvd players/stereos etc. I tend to butcher any old electrical equipment (the smaller the better). The amount of small screws and fittings is suprising and other brass spacers and cogs,gears are always useful. (also small leccy motors if thats your thing) My SE5a has a tiny 6mm crosshaired brass gun sight made from a watch cog. i just mounted it in my dremel and ran it against emery to take the outer teeth off and it is a perfect miniature. Just start stockpiling ( its not like the parts take up much room !! Quote Link to comment Share on other sites More sharing options...
Ernie Posted November 22, 2008 Author Share Posted November 22, 2008 Hi Richard,I agree completely with that...I have found a great source in old 35mm single lense reflex cameras..there are piles of them about, now that we are all digitised, and they are crammed full of goodies.My current problem is that I need around 30 all the same, for around the front of a dummy radial cankcasethanks ernie Quote Link to comment Share on other sites More sharing options...
Ernie Posted November 22, 2008 Author Share Posted November 22, 2008 Hi again Rusper, Thanks again, that last one looks interesting..I'll have a closer look laterernie Quote Link to comment Share on other sites More sharing options...
Allan Jordan Posted November 22, 2008 Share Posted November 22, 2008 Hi Ernie, What about good old BA threads for your model ? they are available in very small sizes... Quote Link to comment Share on other sites More sharing options...
Ernie Posted November 22, 2008 Author Share Posted November 22, 2008 Thanks Guys, BA sems the way to go..Why are thread sizes so confusing? Chronos are the best that I have foundernie Quote Link to comment Share on other sites More sharing options...
Brian Parker Posted November 22, 2008 Share Posted November 22, 2008 Chronos also stock the Zeus booklet. Contains data and reference tables for threads, tapping and clearance drill sizes for both metric and imperial, plus conversion charts etc. You may find this booklet useful.

Allan Jordan Posted November 22, 2008 Share Posted November 22, 2008 Hi Ernie, What do you find so confusing about BA threads, as a model eng. I have been using the BA threads for many years now ? If you would like to have a chart showing drill sizes send me PM with your postal address in france and I'll put one in the post for you, is this any help ? It will be a lot cheaper than buying a ZEUS. Quote Link to comment Share on other sites More sharing options...
Ernie Posted November 23, 2008 Author Share Posted November 23, 2008 Hi Allan. the metric system that I now use seems so simple ie. M3 is 3mm...I can't for the life of me figure out why as BA sizes get bigger, the numbers get smaller..Thanks for the offer of drill sizes, I think i've got one somewhere in the mountain of paper that I call a filing system...ernie Quote Link to comment Share on other sites More sharing options...
