Rob Leech Posted November 17, 2010 Author Report Share Posted November 17, 2010 EDIT: Actually, even for me that was a bit anal. Great work, it's looking good. I see what you were saying with it, but i prefer showing the build in a time line, if you get what i mean. Personally, i hate seeing build threads where you have to search through how ever many pages to see the build in action, but i do agree with how repetitive it can get when your following the build and i apologise for that . Cheers, Josh. Quote Link to comment Share on other sites More sharing options...
Luke Rainbird Posted November 17, 2010 Report Share Posted November 17, 2010 Much nicer to have it all in one post/sequence of posts though - you can follow the whole process and flick back to check stuff. Still mega impressed with this project, Josh. Can't wait to see/hear about the finished product Quote Link to comment Share on other sites More sharing options...
Phatmike Posted November 17, 2010 Report Share Posted November 17, 2010 Awesome work Josh - nice stuff. Can't wait to have a try on it when it's done. Cya tomoz! Quote Link to comment Share on other sites More sharing options...

Rob Leech Posted November 18, 2010 Author Report Share Posted November 18, 2010 Making good progress Josh!

Luke Rainbird Posted November 18, 2010 Report Share Posted November 18, 2010 Looking fresh man! How much tyre clearance are you looking at there? Seems like you've got plenty of room for chainring/freewheel clearance on the outside of the stays Quote Link to comment Share on other sites More sharing options...

Seems like you've got plenty of room for chainring/freewheel clearance on the outside of the stays Should fit a 2.5 quite easily, yh, havent tried it yet, but from measuring up different frames, should be fine Jesus! that weight is unreal ! love that frame ! Ah yeah! didnt originally intend on it being a light weight jobbie All the tubing is 1.6mm wall and after drilling a hole in my dead ozonys and finding it was around 1-1.2mm, i'm quite surprised .

Ali C Posted November 19, 2010 Report Share Posted November 19, 2010 loving the work, that welding looks as good as some frames you can buy too. I do have two things I am not keen on (though one is just cosmetic). You have welded the tubes to the headtube before adding gussets? I was always told this was the incorrect way to do them. My understanding is for the gusset to be working as it should, it needs to be welded to the tube (top or down tube) before cut to fit and welded to the headtube. In theory you should be able to drip oil down the open end of the gusset and have the oil able to get on the inside of the downtube. I understand this allows any flex to be spread down the tube rather than being concentrated at the weld. I am also not keen on Alu frames where the tubes don't meet at the head tube (just ask the guys at Tartybikes!). I do love it with steel frames though and it is just a cosmetic thing, so nothing serious. but yeah, keep it up, can't wait to see the final pictures!

The welding looks alright in the flesh, its just that i no that i can make it alot neater . With the gussets, i will still be able to weld them to the tubes, ive just tried to maximize the surface area of the weld, if you get what i mean. Im going to sand back the area around the tubes where the gussets will sit, so that it still makes contact with the tube, and re-weld it. Just seems a bit weird to me to leave a void under the gusset, but point taken and agreed . Lol, its something that i really like in ally frames, hate it when the join at the top, even more so when they have about a foot and a half of weld along the two tubes, so im afraid im going to have to say no to that one mr C .

craigjames Posted November 19, 2010 Report Share Posted November 19, 2010 There should be a void under the gusset as Ali has said, well that's how it was explained to me. Frame looks neat, welds looks as good and in some cases better than some off the shelf frames, very very light too. Quote Link to comment Share on other sites More sharing options...

Will be different for the next one :$ Cheers, Josh. Edit- Just seen this on tartys- Looks very much like they've welded the down tube before putting the gusset on? Just me?

Luke Rainbird Posted November 19, 2010 Report Share Posted November 19, 2010 That gusset will be serving a slightly different purpose to one on the top/downtube alone though, surely? That's far more of a plate to hold them together a tad more to compensate for them being 1.483 metric kilometrons apart Quote Link to comment Share on other sites More sharing options...

Ali C Posted November 22, 2010 Report Share Posted November 22, 2010 they arn't the worse frame in the world, but I think they could have made it better quite easily (mainly in the looks department) Quote Link to comment Share on other sites More sharing options...
Rob Leech Posted November 23, 2010 Author Report Share Posted November 23, 2010 You need a TIG for aluminium Adam, i am disappointed good sir, ive got 2 ally migs sat in the workshop doin bob all. I wouldn't be looking at the Impulse frames for ideas on how to build frames personally Lol, fair do's Ali, anyone have an idea why they've done the downtube gusset like they have though? Cheers all, Josh. Oh, and mite partially build the frame up tomorrow, just to see how it looks . Quote Link to comment Share on other sites More sharing options...
dirt jumper jake Posted November 23, 2010 Report Share Posted November 23, 2010 You need a TIG for aluminium or just a new liner, gas cylinder and wire for MIG yes? Quote Link to comment Share on other sites More sharing options...
Rob Leech Posted November 23, 2010 Author Report Share Posted November 23, 2010 Yer they did. & sweet frame mate! im thinking of buying a new MIG just for Aluminium If you do, please, o please, spend as much as your budget alows, ally migs are quite specialist bits of kit and they are definitely a pay more, work less jobbie . or just a new liner, gas cylinder and wire for MIG yes? The machine needs to have a pulse setting, its all about removing the oxide layer with ally welding . Josh. Quote Link to comment Share on other sites More sharing options...

How much does a reasonable TIG set up go for, I've got a 3 phase socket in the garage for the MIG plant so that's OK and have some basic experience; just fancy a bit of a play...
