Just to inform everyone, I have found a new supply of the transistor that is used in the twelve volt negative earth 'Beamspark' electronic ignition unit. So along with the standard six volt positive earth 'Beamspark' I have reintroduced the twelve volt 'Beamspark', still at the same price of £40 post free in the UK.
Each unit individually built and tested continuously for twentyfour hours with a two year warranty and serial number.

Had a major problem with the petrol tank, the front left hand bolt had punctured the tank at some point in the past. This had been repaired with a tank sealer of some kind which held for a while until it let go suddenly probably due to ethanol based petrol. A kind friend of mine who is an expert welder cut the plate off the bottom of the tank and repaired the leak. The plate was then re-welded back on and I have to say the black paint finish was undamaged on the tank. My friends name and phone number is listed in           'Companies and Products'.


*** Further Notes : Distributor Blanking Caps.    15th / 10 /18***

Machining up a new batch of Distributor Blanking Caps. These are machined from a solid billet of aluminium and each one is hand fitted to my set of jigs to obtain a perfect fit into the Lucas distributor. A lot of work involved but finishes off the redundant spark ignition system. Remember there is five pounds sterling off if you buy the Beam-Spark and the blanking cap together with free postage in the UK .

***Further Notes :  Beam-Spark ignition Unit                          15 / 09 / 18***

The Beamspark ignition unit continues on for another year, proving to be very reliable and robust. Price unchanged, each unit hand built and tested for twelve hours on a twin spark bench tester. I am now building in batches of ten so can deliver units within twenty-four hours from placing an order. Thank you all that have purchased a Beamspark for your kind and positive feedback.
