  After making a folding spinning wheel for Sue,  
Its made from Wild Olive a beautiful hard wood and the fly wheel is Mopani which has a relative density of 1.5, all the bearings are ball bearings.  
  She now wants a loom to weave what the wheel produces,  
The first step was to design the loom in Google's Sketchup, so learning to use Sketchup was the first step. Each bit was drawn separately and then put together in SketchUp.

Its an 8 shaft 32" weaving width loom.

A plank of Hickory chosen for its strength. I would have loved to use Wild Olive but its 3 times the price. The plank starts out at 25mm by the time most of the saw marks are planed off it ends up at 18mm. The plank planed and cut to size this is just the frame the castle is still to be cut out of a second plank
       
 
Gluing the 6 pieces of wood to make a roller they are on the right in the previous photo.. Assembling the frame The castle starts to take shape. The two garbage bags in the background are the shavings from planning the rough planks, i'll have enough Hickory to smoke with for a long time.  
The guides where the Texsolv cord passes threw the wood been turned out of PTFE (Polytetrafluoroethylene) the slipperiest substance known. Nothing sticks to PTFE so there are groves in the shaft so that it can be glued in place. The toggles are mounted, with PTFE bushes.
Three 60 bits glued together to form a half round and routed with a half round channel to take the bright steel shaft that's going to go down the middle of the roller.

 

 
The bits being glued together, with a few clamps. All the bits of the loom waiting for sanding and varnish, the varnish is touch dry in 24 hours but takes 6 days to fully polymerise and harden when it will sand best. So it can sit there while I work on the steam box to be able to bend the reed uprights. The steamer, steaming a piece of wood so that it can be bent. the steam chamber is made from expanded polystyrene.  
The steam has actually melted the polystyrene. The steamer take Four.

The second attempt was with wood glued together, I used Pratley's quick set epoxy a mistake, the glue was setting by the time I put the clamps on and when the steam past threw it it just came apart. I should have used the same epoxy that I used for the rollers but I was impatient. Here the steamer is screwed together and two bolts all the way threw on the end and after an hour is still holding together.

A test piece of SAP steamed and then clamped in the former. It must stay here for 24 hours. I have to test with the pine because I only have two pieces of hickory, mess them up and I'll need to get another plank. The two pine test pieces had different 'spring back' so I decided to try some meranti, it does not steam bend well both pieces broke in a peculiar way tearing uppart rather than the 'green stick' fracture one would expect.
For test purposes the sides were also made of pine, one to check if the zigzag bit where the castle folds down was right and secondly to practice with the router, which I'm glad I did because it ran away from me twice before I learnt its idiosyncrasies. The hole on the left is where I borrowed a piece of wood to fix the damage done by the runaway router. This project is the first time I've used a router.
I saw worried that the rollers would be to short, when I started to assemble the loom to my surprise I found that the rollers where to long compared the the beams, no problem, on to the lathe and take a piece off. Putting the castle in I discover that the beams are actually to short. One day later the beams are lengthened the bit taken off the rollers put back and an extra bit added ' cause they were too short in the first place. The first shaft is in now I can determine the height of the castle (I deliberately made it to high) and configure the support for the reed.
In the previous image you can see that the toggles don't stay down but bounce back a bit, this is because I didn't cut a slot in them for the cord to go threw. No sweat of to the radial arm saw the blade is exactly the right thickness, clamp things down and off we go, first one perfect second one wham bang and the mangled toggle is thrown up threw the port where the sawdust goes breaking its top off and  flying threw the air with the greatest of ease. So OK this is a ripping cut, so clamp better again first one fine, second one goes air born. So its on to the band saw and a specially ground chisel to make the groove and of course two new toggles to be made.
This is the complete loom everything cut to size and waiting for its final coat of varnish and assembly. The only things missing are the cloth beam ratchet and the warp beams brakes they are over the Atlantic at the moment. Notice how the steamed Hickory has changed colour it bent beautifully. All the wooden bits drying from there final coat. Now I have to drill the varnish out of all the holes and tap the counter sunk nuts, there are 58 pieces of wood and 182 holes.
The Ball winder is 3/4 complete the Swift on the dawning boards,

And now she wants a warping mill!

and of course shuttles.

The castle is fully populated (Sue's pottery in the background). Now for segmenting the warp rollers, 198 pegs to be cut and 198 holes to drill! 198 brass pegs rough cut, now on to the grinder to round off the ends. I used this tool to cut them, it was my grandfathers. Sue & I recently toured the antique shops in nearby Parys and the prices these things go for is wow! And to think I recently tossed my granddads' hand planer as just a useless chunk of iron!
The long delay has been because I got the sizes of the toggles wrong and they were not holding the shafts up, the toggles were opening a shed twice as large as needed. So they had to be redesigned and made from scratch and the reed was not moving properly because I had not bent the wood enough so the supporting beams had to be lengthened and a plan made so the loom could still fold up. I was also making a trolley for the Oxy/LPG brazing set I treated my self to, a very different medium, steel instead of wood.
The first test piece of weaving, only 8 warp threads just enough to test the 8 shafts. The shed
The loom is finished, just some touch-up work to be done. Now I suppose I'll have to tile the bathroom & veranda.
The loom in its new home Folded up and ready for action.
The warping frame - cheep and nasty but it will do the job 'till I've made the warping mill. Sprouted legs and moved to the study.
   
 
The first bit of weaving.
