I like that tip you shared Francis on using the tip of the end mill to cut the grooves on the out-put shaft.  Filed that one away for future use. cheers, tim

Glad you like the trick and the fact that you could have to a try it on your builds Tim!

I must work with what I have as tooling so sometime I have no choice and be imaginative to reach my goal...  The sad part is the fact that these splines will be hidden (as for many details) on the final build... Fortunately the pics will still be in the thread to prove they are there and how they were done!   Take care, Francis

Thanks Daniel, The lack of resources doesn't mean we can't be resourceful in our manner to reach our goal.  Glad you can find something useful with that trick!  Take care, Francis

QUESTION;  Francis, something I've been wondering about.  While viewing the closeup photos, the initial cuts have some flash from cutting, this is normal.  How do you get for instance, the long grooves so cleanly cut and smooth? 

Is the hardness grade of the aluminum you use here greater than let's say,  the usual aluminum material for micro tubing?  I know polishing that soft material is not easy, also all cuts made just smear.  The results you show are indeed exceptional.

The edges of the finished pieces are clean and crisp and not rounded from polishing, same with the holes drilled. 

Could you offer some insight?

Mike..

Hello Mike and thanks for your inquiries!

The aluminum used for most of my parts is the hardest that I can find and usually sold as T6 or 6061. I am not an expert so I don't know if an harder grade of aluminum is available (maybe someone can answer this for me) but the one I use produce good results using a 2 flute style end mill at high speed.  It is always a good habit to make several shallow cuts (0.010'' at a time) instead of a deeper ones that leave marks or bites in the groove walls resulting of too much material removed on a single pass.

The aluminum on those tubbing is soft material and called «cheese or butter» I think by many experienced machinists and it is very difficult to achieve high end result with this kind of aluminum. It is also quite impossible (at least for me) to machine this kind of aluminum, the end mill just creates kind of «plowing» and the results are not the greatest with a lot of sanding and filing at the end.

Hope this is helpful for you and answered your questions, I'm always happy to help as much I can in the limit of my knowledges!

Regards, Francis

Hello everyone,

I had just a few hours of bench time this week so today's update is pretty slim but like we say it's one part at a time...  I made the Lenco shifter bracket out of a T6 aluminum rod and I wanted the handles to be functional so I drilled the bracket edge to edge in order to insert a brass rod as a pivot.  More update later with the rest of the shifter and the mechanism parts.

Comments and questions are welcome and appreciated!

Take care, Francis

Hello everyone,

I do have finally finished all the parts for the Lenco transmission including the shifter handles, all the levers (forward and reverse), rods and jam nuts.  I also made the side supports with a 0.047" brass rod and the mounting brackets are welded on.  The transmission is not finally assembled because I do have ordered brass bolts to connect the gear cases together.  As soon I get them I will make the fanal assembly minus the shiter that will be mounted on the transmission by inside the cab when the floor pan will be definitively glued (a lot of fun in perspective...).  This is my first ever all machined transmission and I'm very happy how it turns out, i will move to the flywheel and clutch set-up.

Take care, Francis

My goodness, beautiful fabrication here.  Such a small scale, this is just delicious!

Francis, thanks for the raw material information.  Yes, I checked online with McMaster-Carr, the 6061 is correct, an aircraft grade aluminum, super hard in comparison with the butter soft micro tubes I struggle to get polished.  What a task!  I found some material I can use for front laced wire rims for dragsters. 

Your updates are a thrill to view....I like this!

Thanks for the compliments Mike!  Glad to know that you found this information useful, you will see on your first try how different 6061 aluminum is in comparison with aluminum.  On the other side it's also more difficult to work with this hard aluminum especially when you want to make a lot of fine tuning manually, but the finish is superb.

Take care, Francis

That's a good one Tim!  I take it as an approbation... speaking transmission, I can't wait to see what kind of amazement you will bring us for the Maverick because amazement will be... again!  Take care, Francis

Wow I'm blown away !

Not been about since the engine build started, just incredible , how you get your parts so accurate and in scale ! !

Really like the anodising, looks even more real with a bit of colour !

Every single component of this build is a model in itself!  That Lenco transmission is just amazing, your machining skills are phenomenal.  This is going to be a beautiful truck!

I just went back through all 14 pages and I'm just speechless! This is beyond amazing! True craftsmanship!

Thanks Brian, I really appreciate your kind comments.  Your own builds are exceptional and the Transtar log truck you build drive me crazy!  I Still have a lot of parts to do so feel free to come back anytime!  Take care, Francis

Thanks for the compliments Martin!  I make a lot of internet searches for the measurements of 1:1 parts in order to make them as realistic as possible.  Anodising is new to me and I do love the rendering and the possibilities of this process not counting that it doesn't hide any details, its like machining a part in already colored aluminum.  Take care, Francis

Thanks Jim!  I work hard to make all these parts and I wish to deliver the best build I can.  I continue to learn a lot and I already have ideas to improve some of the parts I made on my next build.  I love sharing and I learn a lot from watching the work of other members on this forum, it's an endless source of ideas and motivation!  Take care, Francis
