Title: Spanners for Sidevalve Fircone Valve Caps
Post by: shorrog on April 03, 2018, 02:10:58 PM
Hi folks the club is thinking of getting some spanners made for the large fircone valve caps and also a C spanner for the exhaust nuts. Can any one recommend the type of steel we should use? They will be laser cut from 6mm steel plate

I can get these water cut   if you can scan the  spanners at 100%  300DPI  a  local  firm   will cut them   if not   if you can send me  both spanners  I can have  some made  for new spares stock

Hi John
Better still I can send a CAD file in DXF format which the laser cutters and water jet printers can use, we can then get quotes and decide on how to proceed.

You can certainly put me down for a pair of spanners when they're available. Good work, chaps.
On a related matter, has anyone found a reliable supplier of the actual fir cone valve cap? It would save me having to make one from scratch or obtaining a 'blank' from the Austrian supplier. Mine's getting fins as thick as Mr Creosote's proverbial 'waffer-thin mint'.  ;)

Guys can you do me a favour measure the across flats dimension of the Fircone caps and the spark plug holder.

I have measured mine  as 1.727" across the flats for both fircone and spark plug holder.

Graham, the brass cap that holds the 'flint' is 1.730" whilst the fir cone is an ominously beastly 1.666"  :o

Just come across this thread while exploring the forum.  Graham, if it is not too late I would be interested in a set of spanners - my plug holder seems to need tightening every few hundred miles.  Maybe I should get a copper washer too!

Just found a 46mm copper washer on Amazon after failing with normal searches.https://www.amazon.co.uk/gp/product/B01EZZOMZ4/ref=od_aui_detailpages00?ie=UTF8&psc=1 (https://www.amazon.co.uk/gp/product/B01EZZOMZ4/ref=od_aui_detailpages00?ie=UTF8&psc=1)

Better size and thinner copper washer on Ebay!  The 46mm would have needed a bit of filing to fit.  Cheaper too.

Can you included me as one who would like to buy a fir cone spanner too please!

Well done, chaps.
One thing I've noticed though (speaking as a Yorkshireman  ;)  ) is that as I need one of each of the two spanner sizes, the postage for two ordered together is £1.50 more than two ordered separately  :-\ That's nigh on enough for a pint  ::)

Let me check that,  it does not sound correct. OK I had the weight incorrect so it pushed it to the next shipping band.

Try again.
Graham.
