• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

Mike builds a teardrop (cedar roof)

Aesthetics, mainly, (I'm not confident of getting a neat-looking fibreglass joint), but a secondary waterproofing for the joint.



I'm not sure what the correct description is, but "strong" or "rigid" are the starting points. Bear in mind the size. This is smaller than almost any wooden dinghy or tender you can think of, and has got a strong structural bulk-head only 1.8m from the front.
What I ment was that a composite cedar strip boat with epoxy glass is best as that without mixing capping rails screwed through the epoxy glass.

Ah, right. I'm not expecting to screw them on. I hope they'll be epoxied into place, but I might be using a Sikaflex-type product for that job. I haven't made up my mind just yet.
 
You'll remember that I made up the door frame in our last exciting installment. What you may not remember is that the doors are going to have radiused corners. Here's that drawing again:

Teardrop side elev.jpg

To achieve that, I needed to add something into each of the corners of the door frames. In preparation, I made a cardboard template, and glued up some scrap Douglas fir:

IMG_8172.jpg

I thought I'd got it right, but I could only fit 7 of the eight I needed:

IMG_8179.jpg

So, I cut off four of them so that I could get on, and glued on another offcut. That will be ready tomorrow. Here are the shapes cut out:

IMG_8180.jpg

It's worth saying at this point that everything other than the joints are being made slightly over-sized at the moment. When the frame is complete and the ply inner skin fixed in place, I'll place the big template over the whole thing and go around with a flush trim cutter in the router, and bring everything to it's final size. So, these little corner pieces just had their sides squared up on the linisher (well, you know....belt sander-in-a-jig). The curve will be done when the whole wall is trimmed.

I put the frame on horses and cut and pared as necessary:

IMG_8182.jpg

......before gluing the corner piece into place. This part is entirely not-structural. It will be covered by a trim, and it doesn't even have a seal fixed to it. It's aesthetic only (well, it stops the edge of the ply flapping), so don't be worried about the weak looking grain:

IMG_8181.jpg

This enabled me to mark carefully for the sockets for the half laps securing the door frame into position:

IMG_8177.jpg

IMG_8183.jpg

With a dab of helt-melt glue under the bottom ends of the doorframe, I finally had some solidity about the whole frame, and something to reference all the other pieces from.

I don't want to bore you with endless photos of half-lap joints, so here is one group showing how I am doing them all:

IMG_8173.jpg

IMG_8174.jpg

IMG_8175.jpg

IMG_8176.jpg

I then worked my way aft, marking and cutting, and gluing up as I went. I have to say the little second-fix air pinner is brilliant. It's going to save a lot of time and clamping later on (but it's not like I'm in any particular sort of rush). Here's the current state of play:

IMG_8184.jpg

IMG_8185.jpg

I must say I am thoroughly enjoying myself.

I am still shocked at how tiny it is.
Picture it like this, Adrian: it's the size of a full-sized double bed, plus a full width blanket box at the foot. That's its point.........towable by almost any car, and ready to go at 5 minutes notice. It's a camping trailer, not a caravan.

With your head at the door and feet under the kitcheny bit? Not much room to stretch out then.
 
Your wife is very tolerant Mike. Mine would rebel. But she is a wriggler. :cool:

Well, shoulder at the door. It will have exactly the same size mattress as our bed, so we should be just as comfortable in the teardrop as in bed at home. It would be nice if that actually meant a good night's sleep, but those days seem to have long gone.....
 
Here's how it works:

Teardrop trailer.jpg
That's got a 9" mattress, and the teardrop 145mm shorter than the actuality. Chances are we'll have a 5" mattress, so there's getting on for 250mm more vertical space than this drawing suggests.
 
I do like your design Mike, as you say enough room to sleep in comfort and easy to get to the stove etc. I can imagine that you can get into fairly secluded areas where caravans can't go.
 
Will the awnings be fixed or dismountable for transport and installed when you set up camp?

Fixed "bat-wing" -type 180 degree awning with side walls zipped on afterwards. That's the plan at the moment. Something like this:
 
Make sure you include at least two of those hand-cranked "corkscrew" ground pegs Mike, for securing the outer corners of your awning. They are brilliant, as in: "Thank God the awning isn't blowing away in this wind" type of thing. It takes amazingly little moving air for - what is essentially a land-based sail - to invert....seen it happen, chaos and a pain to restore.
I had a 5.35m awning on mine. I set the corners as above, then stretched a towing strap across the width, over the canvas, between the 'corkscrews'. It spread the wind loading across the whole of the canvas, and not just the two corners. Mine was commercial 75mm tape, but for a wee tortoise-shell like yours, and a commensurately small awning, one of the so-called "luggage straps" intended for roof racks and bikes/canoes would suffice.

I worked my way around from front to aft doing all the joints in sequence, and eventually I had all the top done, all the verticals done, and the intermediate horizontal timbers which are for fixings for cupboards etc.IMG_8186.jpg

As you can see in the above photo, the next thing was to fit a horizontal along the bottom of the frames. More half-laps:

IMG_8187.jpg

That was soon glued and pinned:

IMG_8189.jpg

Those joints are blind, deliberately, because I don't want end grain exposed externally, and the under-edge of the frame is going to be exposed to water splashing up from the road. Well, almost. It will have a cover strip over it, fibreglassed, but should any water penetrate I wouldn't want it to find end-grain. It was a big moment detaching the frame from the pattern, involving a few goes through a mental checklist.

Time for some ply. As I said, I have bought poplar ply for this job, and I have been very impressed. However, there are some quirks. Firstly, it is 6.2mm x 1220 x 2500 in size. So, 1/4" x 4 feet by 2.5 meters......a weird (and typically British) mix of metric and imperial. Secondly, it's not square!

IMG_8191.jpg

Ho hum. That just means careful checking on the bits where right angles are required. I clamped 2 sheets of 6mm together, and clamped the pattern on top:

IMG_8192.jpg

After marking out, I found my most rarely used tool, the jigsaw, and cut out roughly:

IMG_8193.jpg

The off cuts show the quality of the ply:

IMG_8194.jpg

Yeah, it's not prime birch ply, but it weighs about half as much as birch, and is definitely not too shabby:

IMG_8195.jpg

I then cut out the back ends:

IMG_8196.jpg

Next, I did some very careful setting out, with the straight edge at the bottom being the reference from which everything is set out:

IMG_8197.jpg

I then glued and pinned it in place:

IMG_8198.jpg

.......and rough-cut the door. Not TOO roughly, as the offcut is a big piece of ply which I'd like to use later on:

IMG_8199.jpg

Sorry, that photo is sideways. This is better:

IMG_8200.jpg

But Mike, I hear you all cry, the ply doesn't reach the bottom of the frame!

Patience. All will become clear. Once the glue was dry, I went around with a flush trimmer, and produced the final shape for most of the wall:

IMG_8201.jpg

My half-laps had worked OK:

IMG_8202.jpg

The trimming went pretty well, but it's not my favourite thing. One slip of the screaming monster and you ruin both your template and the workpiece. I stood it out of the way to get on with the next thing:

IMG_8203.jpg

I took some 150x19 nominal PAR (145 x 14) and thicknessed it down to 12mm thick. Out came the router again, this time with a winged cutter to do a rebate on the edge of the boards. Honestly, I hate the router, and have used it more in the last week than in the whole of the last year:

IMG_8204.jpg

IMG_8205.jpg

That rebate is the same depth as the ply.

Here is the ply/ rebate posed photo:

IMG_8206.jpg

Given the option of getting another cutter out for the router to do a round-over, or having a few peaceful minutes with a block plane, I set the bloody thing aside and walked the length of the boards a few times:

IMG_8207.jpg

That rebate cover the bottom edge of the ply:

IMG_8208.jpg

Before fixing it in place, I made very certain that the bottom edge was straight:

IMG_8209.jpg

IMG_8210.jpg

With the board clamped in it's final position, I took an offcut of the framing material, and marked out for the bottom edge of a joint on each of the vertical frame members:

IMG_8211.jpg

The router didn't get to rest for too long. I fitted a guided trimming cutter, again, using the edge of the PAR as a guide, I formed the top edge of the joints:

IMG_8212.jpg

With a tenon saw I then cut the other edge (after the board was removed), as well as cutting a couple of vertical cuts on the same:

IMG_8213.jpg

This was as a result of being awake at 3.00 last night. You have to think about something.

IMG_8214.jpg

The piece which will fit in that housing is going to be doing a lot of work, structurally, so removing any chance of it twisting or otherwise moving just seemed like a good idea. Next up, I fitted the edge of that board (4x1) into the housing, and marked it up:

IMG_8215.jpg

Before housing out to those lines:

IMG_8216.jpg

Two 9mm housings gave me 18mm of lap, and a really strong junction:

IMG_8217.jpg

After rough-cutting the bottom of the door opening in the pine, it was time to glue that lot up:

IMG_8218.jpg

I decided to use the 502 (non PU) for the top edge, where the board is rebated over the bottom edge of the ply, because I didn't want to be dealing with a heap of glue oozing out of the joint, which may or may not be on show in the finished item. The glue up went well:

IMG_8219.jpg

I went off and did other things for a couple of hours, then came back and de-clamped. I pinned on the template for the lower edge of the door, and trimmed the PAR to shape. It MOSTLY went well. One bit will need some hand-work:

IMG_8220.jpg

IMG_8221.jpg

So, barring a couple of small jobs, that's the woodwork of one side finished for now:

IMG_8222.jpg

Here's a fun little detail, which you'll have to remember for later, when this lot is fixed to the chassis:

IMG_8223.jpg

Talking of the chassis, I'm expecting it this week. Exciting!

Mike, I'm getting the distinct impression that you aren't just making this up as you go along, but have a file full of drawings of every carefully thought- through detail!

You're not wrong. I've been drawing this for a couple of years, Andy. There are still some bits which are quite hard to visualise, and this is one of them. I hope I've got it right!

What's the ledge for?
Is that the outside face?
It's certainly enigmatic!!
 
What's the ledge for?

The ledge sits on top of the chassis, with the wall entirely covering the chassis. The "ledge" is in fact the outer member of the floor frame, and the wall will be bolted down to the chassis through it. It will also be bolted to the chassis horizontally through the lower piece of 2x1, below the "ledge".
Is that the outside face?

No, the ply is on the inside face. The outer face of the wall will be cedar strips.
 
It’s all fascinating Mike, and fairly obviously as you said there’s been a lot of planning gone into this, probably with a lot of revisions?
The little step in the floor edge member I think probably is where the kitchen wall goes up to?

Although I've been drawing this for a long time, it wasn't until I actually had the parts from the trailer parts supplier here at home that I was able to finalise the drawings. That coincided with having a friend's commercially built teardrop here for repair, and being able to take one or two measurements, and also get the feel of the interior. That's when I added the 145mm PAR board under the ply, to get all that additional headroom........so the detail I have just built was only added in the last few weeks.

The little step in the floor edge member I think probably is where the kitchen wall goes up to?

It is. Therein lies a design detail I haven't seen on any other teardrop: the kitchen floor is lower than the bedroom floor, so this piece of timber will be under the floor in the bedroom, and above the floor in the kitchen.
 
This is a facinating build Mike and carried out with the usual skill and attention to detail we have all come to expect from you. I look forward to following along with envy at the level of patience and craftmanship on display.
 
I sneaked an hour or so in the workshop, and got it insulated:

IMG_8224.jpg

The fly battens were to prevent the expanding foam of the PU glue from pushing the insulation upwards. It's critical that it stays flush with the timberwork. In some areas I did a tight fit, much more often, I left gaps to fill with foam:
