So, before I go off half coked and start yelling at the guy who rebuilt my gearbox, can anyone help me diagnose what may be wrong with it... Since a full bearings and seals rebuild, it has been stiff going 1st-2nd and 3rd to 2nd and I put it down to settling in post rebuild. I'm not sure of the mileage since rebuild because I didn't record it on the invoice, I only wrote it on the flywheel when I did the clutch at the same time, so I'm going to have to pull the box to get that info. Anyhoo, I pull into the parking lot of a local business and shift from 3rd to 2nd and there is a loud bang and the disco does a "jerk" like something went through the teeth of a gear and the it is "normal" again. I park and do my business and go home, about 4.5km. Next morning, I'm back to the shop and this is when things start to get strange...I'm struggling to find gears and some of the shifts are almost like a crash box with bad double de-clutching and others are silky smooth. By the time I'm back at the shop, I'm down to 1st 2nd and 5th gears. I park the Disco and switch off and the box shifts into some gears with the engine off. I do my shopping, go out to park at the loading dock and as I'm reversing the box feels like it's "tightening up" as the car won't coast in reverse, it needs to be under power to move. Fortunately, it's only about 20 meters of reversing, but then as I leave, it feels the same going forward, but only for a few seconds while still in the yard, and returns to smooth coasting after that. The drive home has15 traffic lights/stop street/roundabouts to exercise my shifting skills and I work out that I can get 1st/2nd OK, but 2nd-3rd is a lottery of maybe maybe not and 3rd to 2nd is grinding until I match the revs nicely. As it's flat roads, I elect to take off in 2nd and some 2-3 shifts remain poor and I once made it to 5th, but getting back into 2nd at the lights was a challenge involving slipping the clutch to get the gears turning and then it shifts into gear. BTW, selecting Reverse is also a slip the clutch and grind it in affair. So, now I'm debating yanking the box out today or tomorrow while I wait for the old bloke to contact me. He's dyslexic so communications is always a problem with him, but as per human nature, "now he's avoiding me"....🙄 Ideas, please???

You can be justifiably proud of that result!

Have him send it back and refund the purchase price would be my thought. Then again, I'm a carppy businessman...😁

It could be lying on its side on the bench.

I see you fitted a new injector, does it actually work? Perhaps try swapping two injectors on that bank around and see if the snag moves to another cylinder.

Why not try the same approach as you just did but braze a fine mesh over the area to support it? Like they have done in the crotches of this combustion casing. That's a stainless mesh brazed into place to prevent cracking and blow out of the casing. edit to add: Mmmm, should have checked the date on that reply... duh!

Apparently the files are out there, not sure if on his site or elsewhere, but my understanding is that he is the one sharing them.

Go on, get yer teeth into this beauty..... https://www.key.aero/forum/historic-aviation/3d-printed-rolls-royce-merlin-full-size

Look, I waited 2 years plus change before doing the second one, and it had got so bad that I'd feel like I was being electrocuted each turn of a screwdriver, so I'm all for getting in early with a huge side order of irony in there for effect. The Surgeon sent me to a Neurologist for a nerve conductivity test that revealed the fact that the nerve impulses would arrive sooner if a runner with a cleft stick delivered the signal to the probe. The Surgeon then told me the nerves had been badly compressed and that I should prepare for a possible incomplete recovery....yay! I have to say that barring the pain in/under the cut, so far it has been a perfect recovery. I may yet get to ride my Guzzi and my Ape again after an almost 12 year hiatus with tingly fingers....yes, that's how long I've delayed this....😨

My journey with carpal tunnel ultimately led to the discovery of 2 collapsing discs in my neck and a C5/6 C6/7 fusion as well as the left carpal and now the subsequent right carpal surgery. The surgeon said he hadn't seen such bad compression of the nerve for a long time and that he had to spend more time clearing it than he'd expected, so I guess it all adds up to the discomfort and longer healing than my left paw had.

I was told by the doc that did my left hand a few years ago, so it is part of my routine. I'm a fiddler anyway, so I'm always picking and scratching at scars etc which is a variation on massaging. When I fell off my motorcycle I was almost obsessive with picking and working at the scars/scabs and I have almost zero scarring as a result of that.

Aside from the ability to get some return from backfeeding the grid, what other need is there to integrate your solar? Personally, when I can afford solar, I'm most certainly NOT interested in backfeeding for peanuts money from a system that has cost me a few months salary to fit.

Oh, joy... I'm able to use mine pretty much as normal, excepting the pain on the heel of my palm. The acid test is going to be getting back on my bike, I guess.

I work in Gabon, and we can hit the low 40s with humidity where I walk outside and can feel droplets forming on my skin in less than a minute. After 15 minutes outside I'm soaked from midriff to above my knees. It's bloody horrible at times.

Yes, it is weird, because the pain is deep inside of my hand directly under the cut, so I'm putting it down to the after effects of the actual surgery. I'm going to see the Doc when he returns post holiday season for a follow-up and will ask him then. He did say that it was one of the worst cases he'd seen with the nerve very badly compressed, so I guess he had a bit more chopping and dicing to do than expected. My other hand was not as sore a few years ago when it was done.

Stick it in a pillow case, maybe?

I went to the monthly engine run-ups of the one in Cape Town a few months ago and to hear those Griffins running is something special to behold.

Yes, she was the last after we lost one in the Desert en-route to Oshkosh.

I had my right hand done late October and I'm struggling with it, to be honest. I still can't put much weight on the palm of my hand, like pushing up off a chair, and wrist mobility is still slightly limited at the extremes, but on the plus side, all the tingles and electric shocks are gone now. I guess I'm being impatient, but I really want to find out if I can get back on my Guzzi now the second paw is fixed....

Believe me, 30C gets old very fast. We were 25C at 7.30 this morning with 36 forecast and I'm dreading it.

The annular cutters or an end mill should work nicely.

That is a super cool load! I'd have taken a chance and hijacked that, given the opportunity...🤣 As an aside, if the other Shack is in full working order, why not fly it? I'm certain the folks along the route would appreciate the spectacle. Or is it not in possession a CofA? PS, we have this beauty in Cape Town... based here...

No, there are things it can't clean.

Pack the bearing in Vaseline to hold the rollers in place.
