Recumbent Tadpole Trike: Posts on Velomobilforum p.1

I am again looking at a DIY Tadpole Trike. Perhaps this time I can manage to do a little bit of writing without this system crashing and deleting my work.

I am going to make this particular chapter a part of the ongoing forum exchanges with the Velomobilforum online. This is a German forum so I believe I will post there in German and here in American. This way if someone on that forum wishes to view this in English they can and anyone viewing here at the blog can follow along. I will use a translation program to interchange. Google translate or something similar will be doing the machine translation since I do not speak German. https://www.velomobilforum.de/forum/index.php?threads/eigenbau-xyz-spaceframe-vehicle.33109/page-24 is where this conversation is currently being held.

This forum is the best I was able to find for working on the n55 space frame tadpole trike. The trike is a sport version of a cargo trike built in Europe for moving loads. See picture below.

I will be adding more with this title and changing the page number as we go. Ceeann ttfn

Recumbent tadpole trike: Posts on Velomobileforum p.10

I have recently built about 4 possible versions of the tilting mechanism I have beem toying with in my very informal test stand. Here are some pictures of the one I think will work the best. This is pretty much like I think it will be on the actual trike. The orientation on the outer tilting assembly may change a bit but it will be very similar to this. The shocks that are visible should be the ones I use. The tilt arm on the center shaft will be very similar. At this point I have gotten the general outline of what I want to do sketched out in my mind. I have another bathroom to work up and a garage shop to work up before I get back to this little project. Time to get some of the things I put off during the winter done so I can get back to the trike. The things I have been figuring out lately have been the way to get my steering kingpins made and I think that by using a female heim joint and a longer bolt with a spacer to hold the extension of the...

Recumbent tadpole trike: Posts on Velomobilforum p.4 In response to Wolf and Hein, First Wolf's comment. What I am aware of is that there are quite a few tilters that do not use a monolithic steering system and have in fact decoupled the tilt in order to get the system to be stable. The brake application to the tilt is in fact an effort to stabilize the tilt. I am just before work here and have very little time to comment but I will try to cite examples later. Below is a general view of the Aileron tilting trike made by Wayne Soohoo it is pretty obvious wher the trike tilts. He controls the tilt by using a brake released with the steering handles. This is what I based my thoughts on for the theoretical spaceframe tilter. Instead of a remote release I think something like a direct brake would work as well. These data where gathered from http://jetrike.com/prior-art.html#Kurvenleger There are a quite a number of swing arm designs at this site. The above is the c...

Low cost loft bed

This is yet again a distraction from working on setting up the shop... Not an unappreciated one but still... I get to play with the GIMP drawing program to make a scratch design for a very cheap and minimal loft bed. This is designed for a twin long mattress or a twin normal length bed and a space for a built in desk underneath. The desk size and the rail size is not well defined but are sufficient for a build with little guessing. The head board and the back board have cauls glued in place to hold the desk top in place. The subpanels themselves are glued and screwed together in order to ensure solidity and rejection of racking. All subpanels are screwed together in place to make the full structure disassemblable to allow it to fit through doors . The following shows the general structure and the subpanel geometry. I will eventually get a general cut diagram up here and included is ...
