Only the 2 photos of the battery box under construction earlier in the thread.The acetylene lamps I have 3 and a paraffin one are antique.2 Lucas the one with no carbide generater is 1938,the one with is 1924.Don't know the date of the paraffin lamp.And the one in the last photo is a Bauer no date .I have converted them all except the Bauer to led,using fairy lights from the £1 shop and a single 18650.spinningmagnets said:Nice! I like the antique-looking headlight. The originals were very dim, they had a flame that burned acetylene. Nice battery box, too!
Did you take any pics of the process of you building the battery box?

Just factory work.Skills for the build come from metal work in school,self taught welding.Biggest design and engineering influence Valarie Singleton from the British children's program blue peter.Ebikes4Real said:craiggor said:Only the 2 photos of the battery box under construction earlier in the thread.The acetylene lamps I have 3 and a paraffin one are antique.2 Lucas the one with no carbide generater is 1938,the one with is 1924.Don't know the date of the paraffin lamp.And the one in the last photo is a Bauer no date .I have converted them all except the Bauer to led,using fairy lights from the £1 shop and a single 18650.spinningmagnets said:Nice!

That is really quite ingenious, as is the rest of the bike. If you don't mind me asking, what do you do for a living? Tell to piss off if you like, i just find it interesting to hear people's background when they come up with such professional results from their diy projects
This guy got carried away.spinningmagnets said:If that battery box were actually for gasoline, that would be exactly why this bicycles came with a dual top-bar. There was s time when it was common for someone to buy a bicycle, and at a later time, purchase a small one-cylinder engine to add.
When I made a wooden prototype,it shot off the battery when I pressed the battery release buttons.my plastic chopping board ones are a bit more of a tight fit.whereswally606 said:So attempt one made it to made door last night. It fit so well. especially considering id used just a plastic transparent ruler and eyeballed most of the measurements.

I am holding this to prevent the springing forces pushing the sides out

Here is were I went a little wrong but nothing that couldn't be solved without using a file or bandsaw.
Here is todays ungraded v2. thicker sides (increased the sides by 2mm all the way round, removed some of the fillets on the edges, improved the rails so that they are all the way along and adjusted the length a smidge to improve on the issue in the 2nd photo. Lastly 7 m2 machine countersunk bolts hole to allow it to be bolted and glues securely to a predrilled base.
