Extra U-bracket for the Bike mount kit?

Hello friends,

I have 1 Rider and 5 Vintage Motorcycles.

I have the Motorcycle universal mounting kit, works very nice. The problem is that the U-bracket with the big ball cannot be purchased as a separate item.
To get the wanted 4 extra U-brackets with ball I'll have to buy 4 complete kits where the most expensive part must be 12-24 V converter that I already have one of.

Any ideas to get cheap away with this?

Cheers // Ingvar

    Lovely,

    I thought that that the mounting bracket were a TomTom manufactured part.

    Thanks for the link - now I'll have to chose witch type that will fit best.

    Although I have mechanical workshop in my garage I can never get the ball rubbercoated.


    Cheers // Ingvar

    If you know local welder cut a piece of 25mm dia pipe in half and weld two 8mm nuts on either side to match the existing u clamp or make one from threaded bar. Wrap tape around handlebar before fitting to protect same and take out any slack

    If you can not get the ball rubberized consider using brass or aluminium for the ball mount assuming you have accesd to a lathe

    OK tugman,

    I sure have a lathe... But do you really think the grip will be good enough for holding the quite heavy and clumsy device? Maybe the surface should be knurled.
    I will test this before ordering extra balls from RAM in USA. Usually when buying from US or Canada I have to pay customs, handling fees and VAT . This usually costs some 30 GBP and gives a delay of a week or more.

    We still have winter and the roads are severely salted - not very healthy for more than 60 years old bikes.
    Still at least 6-10 weeks until my bikes can experience "Vernal roads" (meaning "roll-gravel" in all curves)

    Cheers // Ingvar

    RAM is everywhere... Check for local dealers: http://www.rammount.com/partners/locations/europe-middle-east

    If you have a 4 jaw chuck you could centre a piece of 25mm thkx50x40mm plate and bore out to the bar dia
    -0.003mm that should give you a tight fit and sufficient room to drill the clamping bolt holes. once done cut the plate down the middle and then have two clamps. See attached

    If not use a length of 35mm dia bar 25mm long and bore out as above cut in half and weld nuts to the two halves.

    Thanks for your link Ste7ios.
    I tried to find this on my own but - as usual - found lots but not what really was looking for.

    I have checked the swedish agent, and they are only wholesale company, however a list of their retailers looked fine. However none of them seems to sell the more styrdy types needed for holding a heavy GPSr on a vibrating bike. Best hit was ( of course ) a large Photo equipment company (where I am registered customer since long time ago). A good starting point as this company is not the cheapest but has the profile to giv 100% support to their customers (who mainly are professional photographers and similair).


    Thanks for your efforts tugman.
    However - my concerns are not at all how to attach something with the 1" ball on the handlebars. My concerns are if a non-rubbercoated homemade ball will manage the forces needed to hold the GPSr in position.

    But after a good nights sleep I concluded that I will try a homemade all metal 1" ball and give the surface some knurls. Knurling a spherical surface is however a so far unwritten chapter in my experience. Maybe I will chose a plain steel alloy (I prefer high grade stainless steel for making spare parts, mostly because the junkbox mainly contains just that).

    You do not have to use the ball method. My bike does not have tube handlebars so I made the a different type of bracket for my rider 2 model to fit to the fairing. This allows it to be locked in place against opportunist theft, while say at a filling up but easy to remove if required. I have just made a modified version for the new 400. See attached photos of the R2
