Worlklog for the 2 Speed Thudster Box Equipped Cruiser
As many are aware i have started a new build that will be home for a 2 Speed box Thud has generously
offered to build for me, along with a re-winding of the old HXT Turnigy to give it some more beans and reliability
Huge thanks to Thud for this, i believe there is a limited number of these boxes being made
i am extremely appreciative that Thud has offered one of them to me for my bike, the generosity of the people
of this forum constantly blows me away, i freaking love this hobby and the die hard developers that continue to
push it forward...Thankyou Todd
The bike, I am basing the frame on a Basman frame-->
^^^This is similar to what i am chasing, i want a lil more ground clearance
and slightly smaller rear end to better fit a 24in rim/ tire combo.
I made a few rough sketches to get the sizing and placement of components, CAD
buffs are in for a treat here BEHOLD
-->
As you can see i still haven't warmed to using AutoCAD (or any other CAD software LoL)
hey! i used a rule this time!...and mathomat mines a lil different
but has circles i used for the wheels :lol:
Not having 'a certain "member from Costa Rica's skills" to build frames accurately without a jig, i decided another frame jig was
needed, this time however a i wanted a re-usable jig for future builds-->
I used a couple of pieces of exercise equipment i found during kerbside rubbish collection
The addition of a new hydraulic height adjustable bench in my workshop has been a god send makes things so
much easier for me, the jig sits upon it.
Currently its set for this new frame, but could easily be altered for next build. I shall keep it stored away between builds.
One issue i have had with the last 2 frame builds is sourcing a 1 1/8 I.D head tube, on both occasions Matt.P has come to the rescue
donating first a OCC Chopper frame and now a West Coast Chopper frame, the headset was cut and cleaned
HUGE props to Matt, thanks again mate -->
I started bending tubes couple of days ago, taking it slow and steady, the tubing being used
is ~31mm OD with a 1.6mm wall thickness for the front of the frame, chain stays will us ~21mm 1.6mm wall thickness
After making a mess of a couple of pieces i finally got the 'lines' i was looking for
in this frame, i roughly cut the tubing to length before I laid the frame out on the
concrete for a better look-->
View attachment 2
Happy with the bends i then went about mounting the frame into the jig
notching the ends of the tubing and tacking it together-->
All the tubes lined up beautifully, they are very 'sturdy' tacs this combined with the jig
holding the frame in position for full welding will see the frame stay in this exact shape
FYI: Frame has ~30 degree of rake for the curious amongst you...
I intended to work on the rear of the frame yesterday afternoon but a mate getting me metal plate
for the rear dropouts didn't come through (his boss was on the lookout all day apparently LOL)
I have some RHS beam here i use as an Anvil i will chop into instead , these will be some more
seriously thick dropouts to make Hyena'sfrock fan bois jealous LoL
So...I positioned some scrap tubing on the rear to get an idea how the rear will come together-->
Hopefully next update will see pretty much complete frame ready for full welding...
As always the build will be delayed due to $$$ and freight wait times, but i shall endeavor
to have this bike finished ALOT quicker time than the cruiser has taken, looking at 3 months
MAX hopefully sooner for full mock up ride. I guess some will be wondering colours i will be using
for this frame? well.. I am going with Satin Black (differs slightly from GangSTa 8) black)...All alloy
parts not polished to chrome finish will
be anodized Blue...Sun Ringle DoubleWide Disc Rim will be used supporting either Schwalbe Tyres Crazy BoB 2.35in or
2.5in Maxxis Hookworms depending how the $$$ situation is going...likely 26in up front 24in rear like pictured bike above...
The drive train...obviously a 2 Speed Thudster box driving via chain on the left side of the bike to
rear sprocket, manual pedal will be right side...very simple.. Hydraulic disks all round
8in front 6in rear..Forks...am on the lookout for some 5-6 year old triple
crown Downhill forks for ~300 bucks...hear of any let me know...Cruiser will run a sensored setup (eventually)
what controller this will be remains to be seen, when time comes to purchase i will see what is going
if it was now, a 18fet infineon most likely with magic from Mr Edward Lyen wavved over it, he is working
on sensorless infineon for these HXT motors hopefully that will materialize sooner rather than later now
he has a pair of these motors to work with...Will run 66v (initially) Lithium Polymer batter config
using GGoodrum boards and balancing system.
Thats about it for now...any thing not covered above ask me and i'll be more than happy
to answer any questions...
Back soon with update...
