Maxx Posted June 16, 2011 Report Share Posted June 16, 2011 Hi, I want to make bigger holes in my front rim and don't want to spend too much time to make it with file, drilling machine, ... I search for milling machine but all I find is that type of machine : It's expansive and not what I want because it's not portable. I want this : But somebody know what's the name of this ? Thanks, and sorry for my bad english ... Quote Link to comment Share on other sites More sharing options...
DeVal Posted June 16, 2011 Report Share Posted June 16, 2011 i forget the name of the secodn machine i think its fixed possition router but with a metal work bit fitted, they are just as expensive as a pillar drill if not more. Quote Link to comment Share on other sites More sharing options...
forteh Posted June 16, 2011 Report Share Posted June 16, 2011 Thats a router table You would need to get a router bit suitable for cutting aluminium but its a pretty expensive way of putting bigger holes in a rim. A cheaper alternative would be to get a tungsten carbide rotary file although they are not much cheaper than a new rim! I used a 5/8" rotary file to open out the holes on my dx32, something like this Quote Link to comment Share on other sites More sharing options...

Maxx Posted June 16, 2011 Author Report Share Posted June 16, 2011 I want a machine for making bigger holes but also for other things (not necessarily in touch with bike). So don't want milling machine, too expensive. Router table, why not I saw some which were not too expensive. But where can i get a router bit for aluminium ? They are all for wood. For the tungsten carbide rotary file, how did you use it ? With a drilling machine ? I thought about the Dremel but I don't know if it's rather resistant for this kind of thing.

I tried a dremel with a tungsten carbide bit when I was doing my dx32 and it just isnt worth doing, cuts so slowly and you will burn the motor out in no time. I used the rotary file in a decent handheld drill (specifically a Bosch GSB 20-2 RE), again its way more than the cost of a rim so why not just buy a new rim? The cheapest way to do it is file it by hand. Quote Link to comment Share on other sites More sharing options...
Maxx Posted June 16, 2011 Author Report Share Posted June 16, 2011 I don't buy another lighter rim because the rim I have is also very light. I just want to make it even lighter by enlarging holes. I've done one rim with file but it takes too much time. I grind my rims one or two times a week on average, so I often change my rims. This is why I want to make the rim lighter without losing a lot of time. Does the handheld drill get damaged with this use? Quote Link to comment Share on other sites More sharing options...

That's absolutely ridiculous and completely unnecessary. What's the reason for doing it so often because even if you rode 7 days a week i fail to see how a grind every 3 days is required?

Maxx Posted June 17, 2011 Author Report Share Posted June 17, 2011 It's an average. I can grind my rims one time in 2 weeks or 2 times in two rides. It depends of the weather conditions, the time you ride and if you have comp. I often ride, and when I have comps I automatically grind my rims. Ride in the rain in a place where there is some sand, dust, ..., and you will see that your grind will hold only the time of one ride. But here is not the question, so does anybody have another solution ? Quote Link to comment Share on other sites More sharing options...
onzatrip Posted June 17, 2011 Report Share Posted June 17, 2011 Tarty must love you..... that's way ott, just man up. You don't want to spend lots on a machine so just leave the rims if there light. Honestly there's no point unless you have the rims over quite some time Quote Link to comment Share on other sites More sharing options...
Krisboats Posted June 17, 2011 Report Share Posted June 17, 2011 Spend the money on a pressure washer instead. Just clean your rims after a comp and they'll be fine. Even a dull grind works well once you blast all the crap off it. Quote Link to comment Share on other sites More sharing options...
Maxx Posted July 28, 2011 Author Report Share Posted July 28, 2011 (edited) Hi, I think I find the tool I need : a straight grinder (combined with a milling cutter). It looks like this : or like this I prefer to have the rim fixed and the tool to the hand rather than to have the tool fixed and the wheel rim in the hand.

AdamR28 Posted July 28, 2011 Report Share Posted July 28, 2011 But here is not the question, so does anybody have another solution ? Disc brake Have a look for a 'die grinder', it sounds like exactly the thing you are looking for Quote Link to comment Share on other sites More sharing options...
Maxx Posted July 28, 2011 Author Report Share Posted July 28, 2011 Disc brake Have a look for a 'die grinder', it sounds like exactly the thing you are looking for I have ridden one year with double disc brake and I don't know why but the only reason I finally prefer HS33 to disc is the loud. I know it's pure mental but it reassures me to hear my brakes to make noise. 'Die grinder' is what I called 'straight grinder' in my precedent post.

forteh Posted July 28, 2011 Report Share Posted July 28, 2011 'Die grinder' is what I called 'straight grinder' in my precedent post. So pretty much what I said to do 43 days ago? You wont be able to use a milling cutter properly in a die grinder, they arent designed to cut at die grinder speeds, you will need a tungsten carbide rotary file as I linked to. Sill cant believe you want to spend so much money and time just to save 20-30g per rim Quote Link to comment Share on other sites More sharing options...
Maxx Posted July 28, 2011 Author Report Share Posted July 28, 2011 You told me 'handheld drill' I found some die grinders with adjustable speed. But that's not the problem, if I must use tungsten carbide rotary file so I will use one. I just searched the tool I need. It's not only for the weight but also because I love to have pimp parts on my bike, doing myself some prepared parts, ... I really enjoy doing mechanic on bike (even if I prefer all the same ride my bike). and as I've already said it, the tool will be not only for rims But also for works others than on the bike Quote Link to comment Share on other sites More sharing options...

I bodged it a bit when I did my rim and its obviously been done by hand. You will get far better control and a neater finish with a proper router table as you originally linked the video to, a handheld tool will tend to jump about a lot.

forteh Posted July 28, 2011 Report Share Posted July 28, 2011 What about a step drill bit? Ive a sneaking suspicion that the holes in question that are needing to be enlarged are not round Quote Link to comment Share on other sites More sharing options...
Maxx Posted July 28, 2011 Author Report Share Posted July 28, 2011 (edited) No it's not for round holes but 'custom' holes. I think it will be good on aluminium if the guy of the vid have no problem with this tube (temper platinum) Edited July 28, 2011 by Maxx Quote Link to comment Share on other sites More sharing options...
