    Project chopper

    Thanks popshot, emil and stormbird. Went to bed with a brain storm and this morning my solution is to add a "downtube" from the seating area to the bottom bracket, It will stabilise the frame and also simplify the fixing of the bottom brackets tube. Then to finish the build and if a problem...

    Project chopper

    here is probably some flex in both, but mostly in the fork, if you bounce the front wheel you can notice a bend which springs back immediately. The fork tubes are 25 x 1.6mm tubes which I thought from the beginning could be a problem. I bent a sheet of 5mm steel into the lower fork holder and...

    Project chopper

    Most of the welds got more tacks on today and a temporary seat and handle bars was added, so for the first time I put weight on the frame. The frame seems rigid enough, but there is some flex in the fork. When I sit on the seat the top of the fork drops about 10-20mm, it would give a comfortable...

    Warrior build - work in progress and questions

    I did it this way, used a standard 90deg wire guide bend, from a brake I think. Worked with no problem for 2 years now.

    Project chopper

    Welded the fork together today and brought the bike out to see if it's strait. Seems ok, but it's very flimsy, because most welds are only tacks.

    drum brake hubs

    I consider getting some drum brake hubs for a tadpole project. Sturmey archer do 2 sizes 70 or 90mm. Is there a big different in the braking capacity of the different sizes? Do you need the 90mm brake hubs for a tadpole?

    My life with Python trikes Mk1 , Mk1.5 , Mk2 ?

    I found a interesting way to make diy vibration dampers. Watch between the 4th and 5th min. of the video. Could it be used for a home made lean joint?

    2wd tilting upright trike ? All terrain ?

    I presume he using 3 - 6, 45 deg cogwheel. Set up like this: 3 cog formation -----{ _ }------ If the left arm lifts up, the left cog turns backwards, the middle horizontal wheel turns clockwise, makes the right cog push the arm down. I'm I thinking right? But they are probably using 4-6...

    Isn't the seats hight over the lean pivot point which make your bike tilt more compared to the python on the pic above?

    My life with Python trikes Mk1 , Mk1.5 , Mk2 ?

    Hi Paul A 50 x 45mm rubber bush can handle about 220kg. It's a trial and error situation, and if no good, estimate a replacement based on the 60' value.

    Stick Welding ~ absolute beginner

    Hi Steve. In my experience a 2mm 6013 electrode is the most suitably size and type for bike welding, I have tried 1.6mm but found the electrode hard to use , to soft, tend to bend when you stricke up, proberly becuse of my inexperience. But be aware all 2mm rods are not equal there is alot of...

    Project chopper

    Hi Popshot, Because the hubmotor is on the front wheel, a god place for the controls unit is around the head tube. I also like to be able to remove the fork for transport, without having to many cables to brake. So having the controls close to the head tube make that possibly. I also have a BB...
