- This is part 2 of the tandem car trailer for the BMW E36 Rally car. I am building it to suit the rally car. It will have a tyre rack, 12v winch, cargo box and anything else I think of while I am building it.

Nice work. You've obviously thought about it before hand, with the gussets and everything. It's the little things like that that make all the difference 20 years later when it's still good and solid and not cracking and falling apart.
Thanks for your comments, hope you enjoy the build.
Really Nice Work! Great Quality Job.
Thanks for great comment 8151noname 👍
Quality build mate 👍👍
Thank you! Cheers!
Awesome bro!!
Thanks Shaine, glad you liked it!
When's your next trailer build?
Hey mate awesome build, just wondering how do you work out the location of the axle on the chassis? Cheers.
Thanks for the comment Harley Gobeo . As a rule of thumb the center-line of the axles (spring center rocker on a tandem) should be 25mm back from center of trailer deck for every 300mm of deck length with a draw-bar length of around 1800mm. So divide the deck length by 300, multiply that figure by 25 and set the axles back that far from center.
Deck length 4.3meters ÷ 300 = 14.3. 14.3 X 25 = 357mm. (I am not going to points of mm) So set the axles back 357mm from center of the deck (not including draw-bars).

I saw some trailers today and they were horrible, CM and Icon brand. My wife told me to just build my own since they didn't have anything over 3.5k axles in stock. I need to haul a mid size tractor and cars I buy in auctions. Well might make a video soon.
Awesome Jorge, can’t wait for the video!!
@@Kaitler_Motorsport_Engineering Just got off the phone with my local steel supplier and had not noticed how high prices are comparing to 2020. 20ft 4" channel $95, 4x8ft 10 guage floor plate $291, 24ft 2"x4" 3/16" wall rectangle tubing $248. The prices increased about 100% and the majority of the steel comes from Mexico which is about 5 miles to the Mexican border. The US steel is available but a bit more $. I think I will have to wait for a dip to build the shop and trailer. Thanks bud.
this is such a nice build ! wondering what kina thickness do you use on the tubes ? looks kinda thin or is it just the angels
kimssonboy Thanks for the comment, the chassis is 100x50x2.5 wall thickness. Plenty strong enough for the job it’s got to do without being too heavy.
@@Kaitler_Motorsport_Engineering ohh yeah nice man it turned out realy nice :) only thing i could say something about is the tie down points wouldnt it be better if you welded Them on a bigger plate then welded Them to the trailer for more surfacearea or is it enough for a car mayby :) and the winchbox was awsome but how is it with water getting in and under the lid if there isnt a lip on the floor :) Still a 9,5 out of 10 😄
@@Kaitler_Motorsport_Engineering sorry if there is some bad spelling English isnt My strong Side :p // Sweden :)
@@kimssonboy Thanks for the question, if it was a machinery trailer I would have had larger reinforcing plates on the tie down but for a car trailer it is just not needed. I try not to add weight if it is not necessary. All the things in the winch box are designed to basically be in the weather so I wasn't worried about making the box waterproof (also in Australia we don't have the amount of rain and I am guessing snow that you might have in Sweden, I don't mean that in a bad way). Also I would have had to vent the battery if it was a sealed box. Mate, your English is way better than my Swedish. I am a bit jealous of people that speak multiple languages!!
@@Kaitler_Motorsport_Engineering ohh yeah i see :)guess the weight adds to a total of how mutch you are able to load on the trailer (less wehight in the trailer more weight to put on it ) :P yeah alot of snow and rain here in sweden and we should not speak about the tons of salt they spread out on the road every year killing all the bear metal and so on so on :/ thanks :) as long as people can comunicate from other countries its good no matter what languge you speak :) but still that trailer turned out so nice you know what you are doing ! :D
Hey mate I’m repairing a camper do you think that a 180 amp gasless mig with 0.8 wire will do the job it’s a shock mount so it’ll be in high stress
Any feedback would help mate thanks
If you’re pretty good at welding you should be able to do it. You need good penetration into the steel without blowing holes in it. Run the power as high as you can for the steel size and balance the wire speed to allow a good penetrating weld. It comes back to the ability of the guy welding it, good luck. 👍🏻
50sk thanks mate can’t stop rewatching this build anymore of these coming up motorbike hitch carrier??
@@perth7930 I am thing of making a motorbike trailer for 2 or 3 bikes, I haven't decided yet! Thanks for watching and your great comments.
Just wondering what welder you got mate? Im thinking of starting a small business. Just wonder if ill be right with a 250mig 15amp
A CIGWeld 210 which is 15amp single phase, I have had it quite a long time, still a good welder. This would be a fantastic machine as a 'do everything' welder for a small business -
*RAZOR™ 250 COMPACT INVERTER - Multi-Function Welder-MIG-TIG-MMA* . I used to purchase welders for the workshop I managed, if you're in Australia Hare & Forbes Machineryhouse have a good section.
@@Kaitler_Motorsport_Engineering excellcent I was looking at a cigweld 250 but ill check out that viper
@@Kaitler_Motorsport_Engineering and i take it your using 0.9/ 1.0 wire? Looks like 2.5 steel? On ebay there is a bloke selling aussie trailer plans. Really easy to follow diagram. All I need to do is take the material list to steelshop. They could even cut it all to length. Id like to think I could knock out a whole trailer in 1 day and spray it with an old compressor the next. Seems straight forward to work at home in the shed?
@@djdanzy Yes 0.9 wire is the way to go, good luck with your build!
Love your work on the Tandem Axle Car Trailer
I have a question if I may ask! What is the Frame tubing thickness.
Kind regards Domenic From Perth WA
Hi Domenic, the outer is 100 x 50 x 2.5 thickness. Other sections are 75 x 50 x 2.5 and 50 x 50 x2.5.
@@Kaitler_Motorsport_Engineering Thank you so much for your reply
Domenic Princi No worries Domenic, hope you liked and subscribe!
It's nice, but,, why didn't you run your A-frame underneath the frame of the main body? It would have been stronger that way, and easier.
Thanks for the comment Jimmy, I wanted a flat plane trailer, so much better when dealing with cars, winching and tie down points (especially damaged cars). I have been using car trailers for 45 years. No it wouldn't have been stronger and I wasn't looking to build something 'easier' I was building what I wanted.
Hey Jimmy what makes you think it would be stronger?
Hi Steve, what angle is the drop on the beaver tail?
Hi Simon, the tail drops 100mm starting 1meter from the rear of the trailer. Thanks for the comment 👍
Thanks heaps for the response mate. Great series you put together here!
Just wondering how much did the material cost
Hi Connor, the axles, springs, guards, associated hardware, wheels and tyres around $1950. Steel around $690. Thanks for watching, hope you subscribed and gave us a thumbs up.🙂
@@Kaitler_Motorsport_Engineering thanks😁
What angle did you do the beaver tail at?
The beaver tail starts 1m from the rear of the trailer, the chassis is made from 100x50 RSH. I dropped the chassis 100mm in the 1meter tail section so basically I dropped the tail the width of the chassis rail.
@@Kaitler_Motorsport_Engineering thanks, you done a wicked job
@@deathrow9565 Thanks for the great comment, glade you liked it! The finished video is up if you haven't seen it.
@@Kaitler_Motorsport_Engineering yeh I did
