Making a Pro Class Rim using an Araya 7X

(1/5) > >>

Peter J:
So I thought I’d show how I do my Araya 7X’s to Pro Class rim, I’ve done it on a couple of my builds because I can never find a set so this is the next best thing as there’s normally  a few knocking about on here or ebay.

Skill wise as long as you can use a ruler and a drill that’s about it and I make sure you wear safety gear because you only get one set of eye’s and fingers.

So this is the safety gear I wear and make sure your in the right type of mindset for undertaking an engineering task.



Tool wise I’ve tried to use/buy kit that anyone can get their hands on. I use to run an engineering firm so I’ve got £1000’s worth of measuring tools/drills etc etc in my garage but everyone doesn’t have that. I got the calliper gauges (the cheaper non-digi type) and hammer from wilko today, the protractor I’ve had from school!!!, the other bits are just general tools......I’ve used a nail instead of a punch because well some people ain’t got a punch. Oh and the drill bit I used was a 9mm which is the nearest size I could find in my tool box!





I use two drill sizes one to make the pilot hole and one to drill the finish hole



Clamp the rim in a vice or work bench



Measure the centre section of the rim....do not measure from the outside because some rims are buckled and not true and this will give you a false measurement.



Half the overall measurement to get your centre line





Next measure between the spoke holes. PLEASE NOTE keep checking this becuase this can hit and miss a bit........Be warned!!! Measure from both holes and get your centre point



Use the nail as a punch to put a “mark” in the rim and hit it ONCE with the hammer !!



Drill the pilot hole.....and try and keep the drill central and also your drilling into a thin wall of aluminium so just use the weight of the drill and don’t push too hard



Go all the way round



Next drill the big hole with a 9mm bit....again try and keep the drill central and also your drilling into a thin wall of aluminium so just use the weight of the drill and don’t push too hard



And go all the way round



After you’ve finished you will have some metal burrs’s these can be removed with either a bit of wet and dry paper or a de-burring bit or a larger drill bit.



If this is too hard you could pay me £15 per rim to do it  :daumenhoch:
