There were two primary reasons for making a new Carriage 

First was using smaller diameter pipe, and second was seeing if using three panels of wood that are tongue and grooved would work for the Carriage platform

In an attempt to keep the weight down and make things more manageable for shipping the thought was to try dropping down to a smaller diameter pipe for the Carriage frame

We had some concerns as far as the strength and if flexing would be a problem!

Happy to have discovered that it looks pretty rigid and should work fine!

As far as the wood platform one of the issues with using panels (panels was necessary if it were to fit in the shipping tube) rather than a solid piece of wood was getting it to hold together 

We didn’t want the user to have to glue it, and using screws or brackets seemed cumbersome 

The thought of a simple tongue and groove was considered to be the simplest of solutions

The panels needed to be bolted to the frame for the casters already so that meant they would have a bolt to fasten them to the pipe frame

Jigging up to cut the groove and tongue was a bit finicky but definitely in the long run seems to be worth the effort!
