dave85 Posted April 12, 2006 Report Share Posted April 12, 2006 Thats been polished though hasnt it.Cant quite see in the pics but the edges look like theyve been re-knurled? Quote Link to comment Share on other sites More sharing options...
the judge Posted April 12, 2006 Report Share Posted April 12, 2006 Cant quite see in the pics but the edges look like theyve been re-knurled?I think you're right as he says it's his old beaten up bash so it would not have perfect edges would itGood job you've done there Quote Link to comment Share on other sites More sharing options...
Bike addict Posted April 12, 2006 Report Share Posted April 12, 2006 A job well done there mate. I made a bashguard for my mod on my grandads lathe and that turned out nice (needs buffing though) but i just cant be bothered to put it on Quote Link to comment Share on other sites More sharing options...

Todge Posted April 12, 2006 Report Share Posted April 12, 2006 You can easily get the middleburn bashguards down to around 100g Whats the idea of the random sized holes?On the hole, looks good, nice finish too. Quote Link to comment Share on other sites More sharing options...
tank_rider Posted April 12, 2006 Report Share Posted April 12, 2006 Nice work. I like the idea of different sized holes on the side of the bash that doesnt usually get hit so not to loose any strength from the side that gets mullered most often.

am4zin Posted April 12, 2006 Report Share Posted April 12, 2006 Looking at the picture of the bashring fitted onto your bike, could you not have machined the bashring to a smaller diameter (it looks like you could easily fit a larger chain ring with the bashring still protecting it)? Or maybe it's a bad idea to have a really small bashring? Quote Link to comment Share on other sites More sharing options...
Such Posted April 12, 2006 Report Share Posted April 12, 2006 its a nice job, though I dont like the new lookIn particular - i dont like those random holes even though they are practicalMaybe drill more small ones and make some good looking pattern Quote Link to comment Share on other sites More sharing options...
westy6565 Posted April 12, 2006 Report Share Posted April 12, 2006 Nice Bash.Looks Sweet, Especially the little ridges going around it, Job well done Quote Link to comment Share on other sites More sharing options...
Endohopper Posted April 13, 2006 Report Share Posted April 13, 2006 Seems well made . Now totally off - topic , but the square downtube on your frame intrigues me ...what frame is that , a Pace ? Quote Link to comment Share on other sites More sharing options...
fubarpatsharp Posted April 13, 2006 Author Report Share Posted April 13, 2006 cheers for the replies fella'smy idea was to increase pimpness without making it weaker to land on (im right footed) so having larger holes where i dont land and small (less likly to crack) where i land.cos i use a single speed tensoiner sometimes the chain tension is ruined by bashguarding as the chain gets hit on the wall, so i went down a chain ring size and only took as much as needed off the bashguard to stop this happing cos it was well annoying.i done this at college with an old lathe and millling machine with a turning table on it.sadly they didnt have a straight knurl at college as i prefer straight to 45 degrees.afterwards i polished it longtime, with 1500grit wet and dry paper for like half an hour then polished it with a mini polishin tool and autosol polishing paste stuff for metals.hopefully this answers everyones questions Everyone loves pictures Quote Link to comment Share on other sites More sharing options...
Endohopper Posted April 13, 2006 Report Share Posted April 13, 2006 Very nice . w00t!!!!11!1 I was correct about frame type . Quote Link to comment Share on other sites More sharing options...
Walleee Posted April 13, 2006 Report Share Posted April 13, 2006 obviously not reet good aat turning then are you lolash Maybe, but at least I can determine how a surface finish was achieved....(and spell)afterwards i polished it longtime , with 1500grit wet and dry paper for like half an hour then polished it with a mini polishin tool and autosol polishing paste stuff for metals.hopefully this answers everyones questions Like I said better than any lathes 'ive used,' any that I have used, are most likely older than you and I put together, and doubled.

fubarpatsharp Posted April 13, 2006 Author Report Share Posted April 13, 2006 yeah the laths at college are well old proberly 20 years oldish.Its pretty damn hard to turn a mirror finish with college equipment as the cutting aint expensive and newIve got a almost brand new middlebrun bashguard for sale that i used on my bike while i was doing my old one if anyone wants it??? silver and landed on it once!!! its well mint condition Quote Link to comment Share on other sites More sharing options...
Ash-Kennard Posted April 15, 2006 Report Share Posted April 15, 2006 20 or 22 tooth? looks good, done to a high standard by the looks of things. Quote Link to comment Share on other sites More sharing options...
fubarpatsharp Posted April 16, 2006 Author Report Share Posted April 16, 2006 im running a 20t at the moment, but could still be used for a 22t but would be close on the chaini left quite abit of diameter on it for further knurling, hopefully a straight knurler will be in at college soon as they last longer.
