****** Mark 2  Beamspark six volt units now available, smaller in size but not in performance £ 35 plus attractive offer on distributor caps and coils !!!!!  ******

****** Comprehensive notes and pictures added to the ' Redundant Spark Ignition ' page regarding the new series of distributor blanking cap.*******

Engine mounting Brace Plate. Mentioned in modifications Page Two.

I have started to make these plates as they can be fitted after the engine has been installed in the frame. A number of contributors have asked me about this plate as they do not have one on their engine. They are required to take the stress on the upper front engine mounting , that is the 'cobra head '.

They are individually hand made from stainless steel. So I am charging £ 10 plus £ 2 postage in the UK.

 Contact me at the usual e mail address.






** CRIMPING **.  I have had returned to me a couple of Beamspark units as faulty. And indeed they are. Connected to the test rig absolutely nothing ! Ziltch, zero , kaput ! However when the customers 'crimped' connectors are removed all is sweetness and light. Sparks abound in great quantities !
If you are going to terminate the Beamspark wires use proper crimps and a rachet type crimping tool. Better still would be to solder the connectors on as the Beamspark units only draw milliamps and a high resistance connector will stop the unit working.    I repair all returned Beamspark units to me for free and that includes the postage back including overseas. So bad connectors cost me unnecessary expense.     Thank you



*********Dear Readers...........The post has been and still is very difficult and long in delays ! Please be patient ! Especially international customers ! For example an oil extender pipe took three weeks to arrive in Portugal ! So heaven help us with sales to Australia !    I have made twenty distributor blanking caps from solid bar, same price as ever, and post free in the UK.      john@sunbeams.co

I do have a new batch of six and twelve volt Beamspark units built and tested ready for immediate delivery. Post free in the UK.*********

Connection diagrams for the Beam-spark units are now shown on the Beam-spark page

** I can now supply six volt twin output ignition coils at £ 40   Post free UK.**

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.
