drive side of the case is in the welders at the moment.
trying a different welder this time, the running around from elite engineering of aintree was too much.
still trying to figure out how to get the cb125 flywheel and stator to fit so a bit more head scratching after the case comes back.

not happy, the welding shop phoned me to give me a quote for the welding. all i can say is the quote was insane so i am now looking for someone in merseyside who does tig at realistic prices.
anyone able to help or point me in the right direction, please

i had some welding done by these people Edwards Engineering & Fabrication Co Ltd Address: Pickerings Road, Widnes, Halton WA8 8XW Phone:0151 423 5624 the cost was £30 but i had a wait of about 2 weeks or so. the gaffer is a bloke called les his ride is an aprillia RS250 and he races a go-kart. this helps as he knew what i was after and why this is what i got for my money i asked for a little on the top gasket face . and a little on the edgs of the inlet gasket face. the side of the welded parts. the welding on the transfer could have gone a little further down the case. but if it breaks through when i do the porting i will take it back. the jobs done today include drilling the falc half of the case for the two studs near the crank (these are not drilled by falc for some reason) also a little grinding on the flywheel side by the inlet to clear the welding. next work? ? ? well i still need to level the inlet gasket face before i bolt the case together, then the case goes back to les to get the gasket face milled. and i`m still looking at fitting the 3 phase stator and rotor. it could get messy and complicated. but if it works it would be worthwhile the internal rotor weighs 0.8 Kg. and as standard will easily survive 13000 rpm. the bike it came from has peak power at 11000 rpm. but to fit it i will need to cut the threaded part off the crank taper then drill and tap the end of the flywheel taper to hold the flywheel. interesting or foolish ? ? this could be interesting

Looks like a bargain for £30, have you looked at the aprilia RS125 ignition? external pickup and nice compact flywheel. Rich Taylor has adapted them for Lambrettas and has some useful drawings on his site.

I`m currently playing with a cb125 set of bits that came very cheap the hope is that i will be able to retain the Khepper CDI that i`m using at the moment.
but i know that richtea does make some quality stuff

Yes, have bought one of his ignitions & looms though have yet to fit it. Lovely anodised CNC stator and fan. Shame you don't see it when it's fitted!

a little playing with the die grinder over the weekend. just a bit of work on the inlet manifold. the manifold as i got it was a load of overpriced crud that needed some welding to make it more usefull. inlet from inside the case at least there are no square corners and the gasket face. i had the face extended a couple of mm to ensure a generous gasket face after blending a little more cleaning up has been done since these pics were taken, but the shape and size are the same and how the manifold sits on the case the view down the manifold. this is prior to me removing a few dingleberries from within the manifold I`m still playing with the CB125 stator and rotor but at the moment it looks promising. currently waiting on a set of engine bolts so i can get the case bolted together prior to going back to the machine shop for milling more pics as and when

I'm led to believe the two un drilled holes on the flyside are for incase a 180cc falc was decided upon. In which case the bolts need slightly further spacing, the main side modified to to work.
Ive seen people weld up the existing holes and use m6 bolts which just bolt in. (welded up and threaded main side.

thanks shaggy that makes a lot of sense.
case is currentley in the machine shop. hopefully it wont cost an arm and a leg as the bloke seems decent enough

got the case back from the milling machine today. the cost was £50 for my case and two others for a buddy. (while i was there i asked if he would deal by post he said "thats not a problem". so that could be handy for others here) so a little work done today, i`m trying to get a 3 phase stator with an internal rotor to fit . the first thing was making a backplate for the honda stator. this was simple enough and a good fit in the original vespa stator recess. the messy part was all the engineers blue which was used to help me decide where to remove metal from the rear of the new backplate this is the backplate in position then the stator where it sits (it still needs winding etc) the plan is to come back to this at a later date and remove some more metal from the backplate after i have worked out a few little problems. and a view from the top. i still have a few things to work out, such as where i can put the pickup and how to mount the two magnets to trigger the CDI. and how to fix the fan to the rotor without reducing the strength of the rotor (still considering many options) at the moment the case is soaking in some scrap petrol/diesle/parafin to remove the engineers blue. tomorrow i hope to drill a couple of holes to locate the stator and backplate. then i come to a stand still while i pay a few household bills and hope that the engine fairy will appear in the night and leave me a new ETS crank. anyone got an ets crank for sale even with a knackered bigend or buggered rod??

are my eyes deceiving me ,8 coils , what 2 for ignition ,6 for lights , similar to modern lml px copys with there external pick ups , nice work by the way , H

3 phase (60% more power than a single phase of the same size), 7 coils for lights etc. possibly 8 depending where the pickup goes. but it could still go tits up if i cant solve a couple of little problems. i have a khepper CDI that i want to continue using rather than spending out on a vespatronic. i also want to use an internal rotor as it has a lower moment of inertia

so you can run smaller coils n still have 100+ watts , nice thinking , whats ya plan for fan/cooling , H

are you winding your own coils , as ive seen various jigs made to do that job ,from old singer sewing machines to fishing reel line fillers ,an fishing rod whippers , ive a mate who winds his own coils for custom guitars he bespoke builds ,will see if i can get piccys of his jig , H

i`ll be doing it by hand it will only take a couple of hours. the ignition coil i wound in the lathe at 300 rpm. still scrating my head about the pick up but i have plenty of time to decide how i`ll fit the pickup and magnets
