    Need some help with a PMR #5 Bottle Engine

    I made one of those a few years ago and was a bit stumped with the same problem, it's a bit of a "catch 22" situation starting that engine frame and I'm sure that the model was designed specifically to tax ones grey matter (there's more to come after that stage ,as Im sure you've noticed!) in...

    Anyone in Hackney, London?

    I'm away from home at the moment in Hackney, is there anyone near here who might have some very small taps and a suitable screw to fix an expensive and well loved pair of glasses?, as I can't find any old school opticians or watchmakers here, a bit off topic I know but thought it worth a try...

    Lost part

    Douglas Adams (sadly not with us anymore) of the Hitchhikers Guide to the Galaxy books describes a portal where odd socks, biros and teaspoons slip through to end up on a distant planet somewhere all together, Im sure that a lot of small parts end up there too! Giles

    Christmas gifts and learning how to hand turn!

    Sorry! I'd forgotten about Holly, which is in fact the whitest and very dense, almost like boxwood but whiter!, I don't know about American holly but I imagine that it must be very similar, if you have a holly tree near you, you can cut off a branch 1,1/2"-2" in diameter, cut to 6" lengths ,peel...

    Arnold's take on Elmer's Tiny

    Hi Arnold, great idea for the heatsink for soldering the pivot pin, when I made my tiny, I may have mentioned in another post, Elmer says in his plans to make a close fitting ally rod so the solder doesn't run into the cylinder, I did that and must have heated it a little too much, as the rod...

Elmer says to turn up a close fitting bit of ally to stop the solder going into the bore, I must have got it too hot as I couldn't get it out again, so I had to bore it out sligtly larger and make a new piston, the pin promtly fell...

    nothing to do with swine flu (we hope!) but I was sent this little story; Grandma is eighty-eight years old and still drives her own car. She writes: Dear Grand-daughter, The other day I went up to our local Christian book store and saw a 'Honk if you love Jesus' bumper sticker ...
