Author Topic: Making a Pro Class Rim using an Araya 7X (Read 19456 times)

Peter J · « **on:** September 10, 2011, 03:14 PM »

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

Skill wise as long as you can use a ruler and a drill thatâ€™s about it and I make sure you wear safety gear because you only get one set of eyeâ€™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 Iâ€™ve tried to use/buy kit that anyone can get their hands on. I use to run an engineering firm so Iâ€™ve got Â£1000â€™s worth of measuring tools/drills etc etc in my garage but everyone doesnâ€™t have that. I got the calliper gauges (the cheaper non-digi type) and hammer from wilko today, the protractor Iâ€™ve had from school!!!, the other bits are just general tools......Iâ€™ve used a nail instead of a punch because well some people ainâ€™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 â€œmarkâ€ 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 donâ€™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 donâ€™t push too hard

And go all the way round

After youâ€™ve finished you will have some metal burrsâ€™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 Â£15 per rim to do it

They did use araya rims at one time.

The early Pro-Class rims were Araya 7x's drilled. I have a set somewhere and you can see the Araya stamping either side of the hole.

Nice how to!

Mate, I wish you would have done this post before Sid tried to do my last one - me and Joff now have a "No-Class" rim each

Your PPE is spot on except you need some safety footwear - flip-flops would be perfect

Yep, I believe so Andy

I had a Sumo 7X rim lying about for ages looking for an orphan ProClass to do exactly this to, but sold the Sumo as Greg needed it. Less than a week after I'd dropped it off Phil Sawzall had an orphan Pro-Class for sale...........
