I was really glad and very privileged to be asked to build a tandem for a couple of previous customers , especially as this bike was for there wedding .
Rudy and Dimity had a good idea of what they wanted in there bike and after a bit of back and forward I had a design drawn up and the fun began . There was a lot of first’s for me in this build ( always interesting and challenging ) the first was using the S&S couplers , as it was for such a special occasion I wanted to do something special for them so I came up with the idea of cutting and filing out hart shapes in the couplers , this was quite an undertaking and took a good couple of weeks to complete but was well worth the effort . I needed to build the frame to be able to handle fully loaded touring so i was using over size tubing but I still wanted to keep a classic look to the bike to this end I cut some and fitted some custom lugs that matched the S&S couplers profile giving a nice look and adding additional strength to the frame . Next new thing was using gates belt drive , a big job working out spacing and tensioning as there is no room for error with the belts . Then to finish it all off my beautiful partner Meg lofts from ahoy birdy made a custom solid silver head badge with their initials carved into it . All in all this build turned out amazing and to have the happy couple ride away from there ceremony on it was defiantly a privilege to be able to have been part of ūüėČ

This project came to me from Bob at Stanmore cycles . The original request was to replace the seat tube on his custom XC hard tail , when I got the frame and saw the rust that had eaten thrue the seat tube and the fact that there was other rust holes on the seat stays I was loth to repair what was very lightly to be a rust bucket thrue the rest of the frame as well , after extensive discussions with Bob we decided to build a new frame . Bob wanted the geo to be exactly the same as his previous frame , I clocked it up in my old jig witch I like to use for this type of build as when it is all set up it stays clocked till the new tubes slid in and presto a dead copy is born , after clocking the old frame up I did find some pretty funky angles going on (75deg seat on a XC frame ? ) and a pretty high BB but even though I tried to convince Bob that a few Tweaks to the geo would make for a better handling bike more comfortable ride he was set on keeping to the original design so I did just that , the only changes where room for a slightly wider wheel and the addition of disc tabs and a brace bridge to support it . With the additional disc tab + bridge and a slightly thicker wall seat stay to handle the loads of disc brakes we where only 10 grams heaver than the original frame ,happy with that .
She is off getting the star enamblers beauty treatment at the moment and Bob should be riding her very soon .

I received Lea’s order through Steve hog of cycle fit he had fit her out for a light wight touring set up so i was off doing the rounds mixing and matching tube sizes and wall thickness to achieve the best results the end tubes selection was Columbas zona set with 8-5-8 butting on the top and down tube Columbus cyclo cross S bend seat and chain stays . The build went together very well with the usual many fiddly hours fitting all the assorted braze on fitting that come on a touring frame . The color choice was spot on and this frame really looks amazing . Lea is of on her first tour with her new bike and I look forward hearing about the trip ūüėČ

This is the second frame I have built for Terry ,
This time round we went for a lovely Columbas life tubed Phil woods eccentric BB single speed frame. In the past I have used 45% silver to fillet braze the aero tubes to minimize heat distortion on the tubes as you have very little play in the way of cold setting with the life tube sets but this time I chose to use mag bronze and a very careful tacking and welding sequence she came out perfect . Terry chose the color scheme for the frame and with all the rest of the components done in black this will be a very striking bike . Hope you Enjoy her Terry .

Well I just got back from the first Australian custom bike show , and what a weekend it was . There was an amazing selection of beautiful bikes and accessories on display from all the builders in oz but the best part had to be that all the builders where in one room ( to my understanding it the first time it’s happened over here ) this gave punters the opportunity to put a face to the people they had heard about or been following and to see up close the workmanship on display , and from a builders perspective it was fantastic to see what others are producing and through around ideas on what people use and why . All in all it was an amazing event and may thanks go to Andy from fyxomatosis for organizing the event , and I’m already working on ideas for next years show . Hope to see you there .

well this was a huge project .

Peter came to me with a couple of prototype frames that he had built him self (very nice work to) any way after talking to Peter and seeing his frames I took on the project of building him 2 frames one for him and one for his partner but i liked the concept so much i decided to make 2 more one for me and one for my partner. so now i had 4 frames to make

well after a lot of cad work i had all the fittings drawn up and then sent them of to get CNC cut buy John from cycleunderground, john did a fantastic job as always while he was cutting the fittings I had to design and fabricate custom jigs for each section of the frames 5 in total, This turned out to be a time consuming and fiddly job it took almost 3 months to complete them.

next process was to start to build each section again with 4 frames to do this was a long some times painful process but it was cool to start to see them come together .

whilst the building was going on I was working with Peter to organize the wheels , as the bikes use 12” wheels there are no options to build any sort of quality wheels with the rims that are available in the market so i organized to get some custom 24 hole rims made up for the builds ,but with the minimum order for custom rims being 200 units i have quite a few still under my house. next in the wheel saga was cutting custom spokes, peter used his cad skills to draw up the spoke lengths but what works on the screen does not always play out in the real world and lacing the wheels required several sets of spokes to be cut till i got the sizes right and let me tell you lacing and tightening 12″ wheels really sux . I was well happy to see them all finished .

As the design was not mine and every change that i had to make as i came up against them had to be checked with Peter to make sure it would not affect the operation of the folding , It was a big relief when i dry fitted the first frame together and it all folded as it was supposed to do.

I had Peter and his partners frames wet painted buy the master hand of Peter of star enamelers and as always they came up beautiful . for my frames I was trying out a local powder coated John at advanced abrasive blasting and powder coating with fantastic results he does amazing work and we are working on some very cool color options at the moment for the last frame that i will be displaying at the custom frame show in Melbourne in Dec.

one of the main faults with Peters original design was the handle bars the first time i rode his test frame the bars folded under my arms and i was only roiling around the car park so I spent a lot of time coming up with a simple yet very solid braking handle bar set up. the end result is very nice and i have no concerns about them letting go under me .

well the last thing is how do they ride, i have to say very well the design is very solid with very little flex threw the frame they fold down quickly and neatly and are comfy to cruz around on, the 12 ” wheels are not the best for holding speed and you dont want to find any deep pot holes but the frames will accommodate¬† 20″ wheels but you cant fold it with the 20″ wheels in the frame. but I really enjoy riding my little bike and im looking forward to hitting up Melbourne on it in Dec .

All in all this was a monster project that took a year to complete and to many hours to count and though i have a lot of ideas to improve the design further I wont be going back to building these monsters any time soon.

Here is a couple of shots of Keir’s new track weapon. keir asked for a curved seat tube on his ride this is something I have been getting inquiries for so I thought this was a good excuse to invest in a tube roller . it took a couple of goes to get the curves i needed but the results are well worth it . keir wanted a solid all most industrial look¬† for the frame and i was happy to oblige this frame has great lines and a serious look to it . Keir is getting the frame painted down south and i am really looking forward to seeing her all built up . keep an eye out for updates in the future .

Terry’s SS silver brazed kick ass road frame

this is Terry’s stainless tubed frame .

Terry came to me looking to get a titanium tubed road frame but as I explained to him , I have been playing around with TI for a little bit now just getting to know the medium and welding up small pieces to teach my self how to work the metal but I was not confident enough with the material to offer it out as a frame just yet. To this end I had been reading up on the new SS tube sets that where out there and I soon found out that the specks of the SS tubes where on par and in some cases better than titanium and they can be silver brazed so I would be able to work with the welding medium that i specialize in and if all the data sheets ran true have a very light and lively rust free frame at the end of the things.

After talking Terry threw his options and drawing up his frame in cad we came up with the final design which was a pretty easy task as he had been fitted up by Steve hog from Cycle fit and there was only a few mechanical changes to the design that need to be made.

I was a little apprehensive with this tube set as I knew from the specks that it was very very hard and SS is a tricky material to weld with it behave very differently when heated, and being on the very expensive side of the tubing price chart I was defiantly steeping lightly with this one.

the first problem¬† I encountered was mitering the tubes, I have some very high end silver brand machined cutters That I use for very light and aero shaped tubes they are dead true and very expensive, With SS you have to use a lot of coolant and a slower cutting speed to stop excessive heat build up that will destroy the cutter and work harden the tubes making then even harder to cut and work .With this in mind I spent a lot of time setting up my mill to get everything running correctly, the first cut gave me an idea of how hard this material¬† is .The stuff is unbelievable each cut was done with a prayer and held breathe but I got thru them all till I was on the last cut. I was all set up with a brand new cutter all going well till it broke the surface and there was a very loud bang¬† not the sound I wanted hear and I figured that was the end of that tube. after stopping the machine and dropping the table to inspect the damage I was very surprised to see the tube un harmed , I’m thinking score lucky break there But as I cleaned the cutter to my horror I see 3 teeth missing from my brand new $360 cutter. I was having a bit of trouble coming to terms with this, the tube I was cutting has a wall section of .7 of a mm the cutter has a wall section of 2.5mm and is hardened and ground! I knew the tubes where hard but this blew me away.

Though I was bummed about the broken teeth on the cutter one of the main reasons I chose these cutters is that they can be reground with new teeth so I thought sera sera ill just have to get it re cut but on closer inspection i found a hair-line crack running the full length of the cutter “F#%@’ $360 gone in under a min welcome to the wonderful world of¬† high temper tubes.

After switching to another cutter I very carefully finished cutting the tube .

With the tube set cut and dressed it was onto the next challenge the welding.

Thin walled high temper tubes are always¬† a challenge especially when they are silver brazed¬† . Controlling the heat between the different wall section tubes yet making sure that there is enough heat for a solid molecular bond between the material’s¬† whilst working up¬† the fillet and making sure not to burn of the silver flux has taken me a lot of years to master, through into this mix the very quick heat transfer of the SS tubes and I was kept on my toes gluing this¬† frame together.

Terry wanted a frame that was classic but not to old school l so I went for a good mix of fittings to this end giving the frame the small touches that really give a hand-built bike its individual character.

the last thing was a custom SS logo done it Terry’s initials but in the end I was concerned that the amount of heat that I would have to put into the frame to fit the badge was going to upset the welds and there was a real chance of it distorting the thin-walled tubes and putting the frame¬† out the alignment.

Well the frame is of at star enamelers weighting for its turn in the line up to get sprayed, Terry is still working out his color scheme but at last count it was looking like a hot red with wight  panel , what ever way the color ends up this will be a very hot looking bike.

I’ll put up some shots of the frame and bike when it’s all done .

Stay upright Tarn.
