1:1 Scale Renault FT
Permalink   


Thought I'd share a picture of my 1:1 scale Renault FT.  Its built from a scaled up 1:35 RPM Renault along with some measurements from a US version M1917.  Its made of wood and steel so its a model and not a real one.  Its powered by a Honda 13 HP motor and uses zero turn mower hydro transmissions.  Works pretty good but doesn't turn as well as I would like it to.  I also need to fix the axle shafts and use stronger steel.  I noticed that the RPM turret roof has a much greater slope that you can really see in 1:1 scale.  So I rebuilt that part of the turret using the Takom 1:16 model for measurements.  That version isn't shown in the picture.  It took me about 8 years off and on to build it.  Just wanted to see if it could be done and use it for reenactments and living history events.  The yellow color really isn't that yellow in person.  The lighting in the picture makes it look more yellow.  I appreciate the information I've gotten on this forum in building it.

That's what i call modeling, what a great job, what was the most difficult part of the build? Something i would like to do but its working out the measurements from a model to the real thing. I have a Takom 1;16 FT but would like to see how far i am out with the calculations to an original part, the more precise the better the fit when its put together, shame there wasn't a blueprint plan pack. Once i built one of these i would have a go at a Mk4.

That looks excellent Warren. Can you give us a bit of a run-down on the construction? In particular I'm curious about the tracks; what material did you use for those?

Cheers,

Michael

Thanks all for the comments. I measured the individual parts and constructed it on the computer using a free 3D CAD application called Google Sketchup. I was surprised to see just how well everything fit together when I built it out. I did a tracing of one of the most complex parts, the engine hatch covers, and my part was almost an exact match to the tracing from the real hatch cover. So the scale models are pretty accurate. I would say that's the hardest hull part to make since it has no right angles. The best way to build the hull is by making the hull panels first then building the steel frame to support putting the panels together.

The track pads are 16 gauge sheet metal. I had the pads cut and stamped to the correct shape by a metal shop. I made the rest of the track parts myself using a bit stronger steel, 11 pieces per block in all. Then I welded up each of the 64 blocks. That took all last summer. I also had the sprockets laser cut from steel plate then did some additional welding of some parts to make the sprocket teeth wider. All the rest I made from scratch in my garage. I recommend a web forum called scaledtanks.com where ideas are shared for building mainly 2:5 scale driveable model tanks.

Thanks Warren. I'm a member of Scaled Tanks and pop on there for a read from time to time.

Hi BC312,

If it's the scaledtanks.com forum you're referring to, the moderator (Arkane?) keeps a pretty close reign on things there and does a good job. The forum is active, I was on there last night catching up with posts.

Cheers,

Michael
