Well this is one special ride , a good mate Steve Hinchliffe test rider for mountain biking Australia told me he had come up with a great single pivot frame idea I was keen as to get involved . Steve had come up with a great linkage design using the linkage programs , I took the points from his design and transfer it to my auto cad program and create a frame based around the suspension positions . Being a prototype I wanted to build a frame for my self to start with to make sure it all worked and nut out any bugs before I built one for my mate . The main frame came together pretty quickly , I then spent a bit of time working out how I was going to construct the swing arm . As with all my builds i like to try new things and test new ideas and this build gave me a chance to try something that I have had in mind for a long time. I love the look of the lattice sub frame on ducati moto’s and had wanted to do something similar on a bike and this swing arm turned out to be the perfect opportunity. This frame was designed to be a 29″ frame but I have been very keen on the 650b wheel size so I added a couple of changes to enable the ability to run either wheel size , to this end I use my eccentric BB to be able to change the bb Hight and with a 200x 57 shock for the 650b and 200×50 for the 29″ wheels and a very short 420mm rear wheel length and 6″ travel this was looking like a great bike .next was the finish, I played with a couple of color ideas but with all the beautiful fillet brazing I wanted to try the clear powder coat again and the boys at advance abrasive blasting did a spectacular job as always 😉
As with all new projects till you get to ride your new creation you can never be sure how it will behave , well first ride blew me away this bike climbed amazingly and held it own even better on the down hill run but being something I had created I needed external input to see if what I thought shared buy others , enter Steve the prefect tester as he is on all the latest industry bikes every for this work , well his first quick test ride ended up stretching out to over an hour ride ( as I sat in the park weighting ) and the smile on his face pretty much told me what he thought 😉 truly a special riding bike . I am refining and modernizing a few things but I will be offering this frame as a custom production frame . Keep an eye out for the next Sapien incarnation .

Well here is another build that is a little different , Ben asked me to build him a cargo bike that needed to fill a few specific requirements he wanted the handling and response that you get from a pull pull cable steering sys and a big carry bed but most importantly it had to be very strong as he would be carrying around his most precious asset his new born son. So I set to work creating his super cargo frame, I have been very happy with my cargo bike and but i was very glad to have this opportunity to improve a few things with this build. with all one off complex builds there are always many challenges to deal with and this build was no different but the end results have come up to and bettered my expectations and I am very much looking forward to seeing the complet bike built up and running. Well if you live in Brisbane look out for a crazy green cargo bike rolling the streets.

Well it has been a couple of years since I first came up with the idea of building a short travel bike . lots of time spent on auto cad working out angles geo and clearances, originally I had planed to get some plates CNC cut and have the swing arm as a bolt together unit but as happens I kept putting other (paid jobs) ahead of this build . I have been working on a new suspension frame design with a good mate who is a gun when it comes to suspension design so I figured now was a good time to revisit my half finished frame re working the swing arm design to be more in tune with the style of frames I am planing to build in the future. To this end I learnt a lot and I’m very happy with the end result, I’m looking forward to seeing how she performs on the trail.

Stay up right 😉

Well this is Keir’s third frame with me this time round it’s a beautiful stainless steel lugged road frame. Keir had been talking to me for some time about creating his own marque frame and after a lot of back and forward we came up with the design. The frame uses KVA SS tubes matched to llewellyn’s clean cast lugs, with brush finish rear stays and custom decals this was going to be a very high end build.
The SS tubes are always a bit of a challenge to work with they are super hard and very tricky to miter, so with delicate hands and good patience the frame started to take shape and soon we had the raw build done, for the forks also used llewellyn lugs and Columbus straight blades these matched the frame lugs to give the bike a complete look .
A lot of time went into the braze on fittings and brushing out the rear stays to a uniform finish.
Next it was of to star enamelers to get masked up and sprayed down , while Peter was working his magic with the paint Meg from candy cranks came up with the custom McLennan logos for the frame, when the art work was finalized the decals where cut but Greg softly and Peter applied them to the frame before the clear coat went on .
All in all this frame turned out beautifully and I was super happy with it when it was all done, did a fantastic job of building up the bike and was kind enough to let me display the bike at the ACBS.
Keir will be marketing these McLennan frame and fork sets to buy in a range of sizes and color options so check out the photos on McLennan cycles face book page.

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.

well this is Terrys SS frame back from the painters and man it sure came up a treat .

This build has been a great challenge and the frame really is one of the best I have built to date . she came in at 1.4 kg and looks like it will be a very lively frame to ride .

Ill put some shots up when Terry gets her all built up and gives me a review on how she rides .

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.
