To learn to stick weld it’s better to start with at least 6mm plate. A hobby welder would not be easy as the current will collapse as soon as you try to start an arc. It’s best to learn to gas weld first as it’s slow enough to see what’s going on. There lies the next problem, you need good eyesight.
I’m qualified in welding to the extent that I should either be inspecting welds or designing them. I also used to teach welding for a while. After the students had qualified I told them if the weld was important, let an expert do it. At least they would know if the so called expert was up to the job. A one year, 3 hours a week does not give you the experience.
I don’t have the dexterity to make the welds look pretty, but I know I get good root penetration and that’s the most important bit. BTW anyone claiming to be coded at welding is just bragging that they achieved a viable weld in a set condition, not that they are qualified.
Any way moving on from laying pigeon poo, the kitchen cabinet is back in Betty. Anita made a test drawer to prove the fit. Not so good, my countersunk screws hit the rollers. Try a slimmer drawer and see if that cures it. Once we have them slipping in and out pain free, we’ll brave making a dummy front to test drawer catch ideas.
I’ve used 25mm pu insulation to divide the drawers and put some more sticky foam insulation behind.
After spending a long time repairing holes, I decided to make some more. Yes I know that they are not vertical to each other, but I decided not to cut any structure out of the walls. One thing I did notice was that stainless steel screws don’t like biting into stainless steel sheet. Galvanised steel screws worked a treat. Another mistake made was not to measure from the same datum. So each vent is not horizontal to each other.
Still more plumbing! The M2 4kw eberspacher has now been purchased, so holes need to be made. Big holes as I’m using 90mm ducting. I was hoping to mount it side on under the step. This would have allowed clean easy runs for the intake and exhaust. Being forced to mount it to the bottom of the step I’ll have to make a top hat pedestal. This will allow the intake and exhaust pipes to bend away from the ground. Pictures on this later. Shown is the flexible hot air pipe escaping from the step and retuning back inside. And of course it fights for space with the water pipes. Another water heated fan is offered in place and I think it will stay there.
I should have been doing other things today, but one gremlin needed dealing with as it was calling my name. Also an opportunity arose, so it would be good to take care of that too.
Whilst boring holes yesterday and killing hole saws, I decided to do an easy one and add another bit of plumbing at the back. 92mm hole saw is supposed to be good for 90mm corrugated ducting. It’s not!! And the new hole saw didn’t like cutting the wooden floor.
So armed with a sharp half round file I thought I’d soon get the better of this. The hole laughed at me! Better weapons required. Industrial flexible shaft grinder with a 25mm spiral band. It’s an abrasive band mounted on a rubber holder. The grit is resin bonded. It didn’t take long to resize the hole. As I was under the main floor l cleaned and reshaped some steelwork that I had previously roughly cut with the plasma cutter.
Two Tee pieces joined with some ducting and I’m through the floor. I still have to make an adapter so that I can fit an air outlet to restrict the flow. I don’t want all the hot air heating the garage space. The other side will match, but that’s a job for another day.
So I hoped a more pleasant job. Two eberspacher controllers to mount. I was hoping for some kind of symmetry, but I thought I’d better look first. Caught you! There is a redundant handle under the moulding, there goes my symmetry.
Wiring can’t be hard? Pins in plugs, no problem. Even locked in place. Now I wondered why I had been given some pins for the sockets? The loom had incompatible connections on it! Then the new connectors need a suitable crimping pliers that I did not have. Not nice, but I made do. Better still the water eberspacher still works.
What a weekend, even with Anita’s help on Saturday very few of the planned jobs got completed.
Anita’s was tasked with modifying the angle section that mounts the curtains. The idea being to attach some z section aluminium to hide the curtain track and mount the over head lockers. Lots of holes to drill and mastering a violent air powered rivet gun. At least that job got completed.
My first task was to mount and commission the M2 eberspacher. I should have taken more time, but I really don’t like sheet metal work. So a rough looking plinth was fabricated in twice the time a good man could have made a nice one.
Typical, the heater didn’t line up with the hole l cut in the step. So out with the flexible shaft grinder and enlarge the hole.
Routing the wiring loom. Even though I had more than enough cable I took the shorter direct route across the step. This will need some p clips later. A couple of hours later I’d managed to feed them though the wing panels. Stress was building and light was failing, time for home.
This morning full of enthusiasm, it wasn’t to last. Fuel and power needed to be routed along side the water eberspacher plumbing. Cable ties had been left loose to aid this. Still no fun as the back is on ramps and I was under the front.
Power connected and just the fuses to fit before it bursts into life. So fuses fitted and some kind of fault code pops up.
So continuity checks done, but still the unable to communicate code. The day ends early in frustration. I wonder if I was sold some duff stuff. Email Mellors in the morning.
So finally made contact with Mellor's, The new eberspacher is going back. It seems it may not have the latest firmware. As they can't "flash" it, either a new ECU is required or a new unit. Could be a couple of months. I really don't want this to be a three year build
Had a call from Mellor’s today, it was an ECU compatible problem. A new one should be fitted in a week or so. Faster than expected, still lots of other jobs to do. Disasters at work with compatibility problems, so the next four days might get spent with this wreck.
So this weekend has been about “what can we finish?” Not strictly finish-able, we decided to tackle the overhead lockers. Sooner than expected we discovered that some of the material purchased for it was used on the sink cabinet. Though we were able to do enough for a trial fit of the cooker extraction unit. Whilst it was in place it made sense to temporarily wire it and check it’s functions. The shower fan was subjected to the same. More aluminium required, best work out what is required for the shower too.
I seem sealed some of the underside yesterday and Anita painted it today. Where ever you look there seems to be so much more to do.
