Hello, sorry for using English but I need these chassis rails for an 8x4 rigid tipper truck project. Maybe someone who has these Carson 1m blank (NO HOLES drilled in them) frame rails here can understand me and answer in English as I speak very little German! Please can I ask ;-
1. What are the dimensions of the cross section in mm ? (please can someone who has them measure them fairly accurately with a digital calliper)?
The Tamiya frame rails that I am experimenting with (from my MB1838LS) are an unequal angle U-shaped channel section of 21.2mm wide (0.834 inch) x 7.05mm (0.277 inch) external size x 1.5mm (0.060") thickness x 388mm (15.27") length, as a comparison.
2. Do these Carson 1m long chassis rails have "square roots" i.e. does the inner part of the cross section have 90 degree corners or are the inner corners rounded like a U channel section of cheap, non-machined, hot-rolled steel.
Here's a link to the item ;-
http://wa-rcmodellbau.de/RC-Trucks/Zbehoer-Trucks/Carson-Rahmenprofil-2x1-m--fuer-Trucks-500907063.html
(about 19 Euros including 19 per cent German VAT, or about 15 GBP)
They are available on Ebay also for 15 GBP plus 13 GBP postage from Germany.
The description is "Carson Rahmenprofil 2x1 m für Trucks 500907063", seems to be Tamiya item no. 907063.
3. And are they Aluminium like the originals?
They should be Aluminium if they are the same as the Tamiya 1/14 truck rails, so are quite easy to drill with Tamiya's small electric hand drill that I have, and I would actually drill the holes in the blank chassis rails by clamping another chassis rail with the correct holes in it firmly to the blank frame rail and using it as a jig to drill the holes without having the drill bit wander off centre, and for other holes I would be using a centre punch to guide the hole being made and stop the drill wandering. I also have a bench drill for doing this stuff but it's out in the shed (it's freezing cold out there LOL).
We are having a discussion about using blank chassis rails (U channel section) to make 8x4 trucks here ;-
