This happened at the weekend, and I just childishly found it funny.

I think you'd be surprised at what a properly used Loctite will do; it's replaced a lot of light press-fits.
Loctite's superglue only sticks rubber. And skin. ;D

 


Something like Loctite 638 would assemble axles for your toys :y

I'd actually be impressed if any general adhesive would be strong enough, as it has significant torque.

Think around 150A at 22v, probably bursting to 200-250A from standing start hard acceleration.

I can't get my head around the current requirements.

That's not a general adhesive, but one specifically designed for this sort of job. As I wrote earlier, adhesive fits are quickly replacing ones that used to be made by pressing parts together. Parts that are bigger, heavier and under far more load than an RC car.


My repair was done with ordinary 2k epoxy because it doesn't matter, using procedures that match: I 'measured' the bore with using cheap drill bits, machined the spigots and stub axles until they just fit, and the only lengths I measured(with a rule) were the hex and track. I've don't know what plastic the axle is made from, and I think the aluminium rod I used was once part of some racking. This is a job where good enough is a very low bar.

Superglue became widely available after it was found to hold the space shuttle together ok.  ;D

Yes.


Although you do need to be careful which O-rings it gets used on....

My sister turned up wanting a cable-tie for this:





Her boyfriend has lost the 'nut' that goes on the end, and works like a wormdrive clamp.


A cable tie would work, but I've  a lathe and some 22mm nylon rod, and the 'thread' is a simple 2mm pitch so





No real precision there; I drilled a 12mm hole and cut the thread until it just cleaned up, because the tool is a stock V-form and the part has straight sides.


Finished, with a quick knurl and chamfered edges:





I should have measured the length, as it could have been a bit shorter

Didn't this happen after people decided it would be fun to apply it to a toilet seat and then see what happened. ::)

I've previously mentioned a friend's VVC Metro that we spent a while correcting all of the 'builder's oppsing awful workmanship. Part of the philosophy was that everything we refitted got cleaned and painted. It's been on the road for a year, and has just failed the MOT on emissions(which is the only real problem), a pair of tyres(disappointing with under 20k miles on them) and both front wheel bearings.


So he dropped these off:





which were salvaged from a car he paid 35, and has provided all sorts of useful bits. These show that the car had been standing in a field for several years, and it took this to remove the driveshafts:





I had intended to press out the hubs and bearings, but it's low on oil. Which meant resorting to a hammer and drift for the hubs and the toolset for the bearings:





which left all this scrap:





We couldn't have used the splash shields even if they weren't rotten as they don't fit behind the vented discs.


I degreased, wirebrushed everything then mixed some 2k gloss black and brushed it on








Puts a nice finish on the cat, too 8)





That should save a bit of time next week when he arrives with the car and bearings. I'll make a bracket for the extra MGF engine mount while the car is jacked up.

About three weeks ago, Deb arrived with a broken door handle on her Hyundai.


We couldn't find a used one(there were plenty for the other side) without importing from Spain or eastern Europe for about 50. New ones are about the same.


So she bought 2 new ones, from a Chinese supplier, for 16 delivered:





The only snag was at least a fortnight delivery time.


Which meant a quick&dirty repair using some M4bolts, 2mm stainless sheet and some epoxy:





I did that without removing the part, and it would probably last for some time. It would always be really ugly.


The new ones arrived yester day, so I fitted the necessary one:





One of the things I like about this car is the sensible way it's assembled: all that was needed to change the handle was to remove three screws, and pry the cables off.


The new ones don't have the horrible soft-touch coating, so I'll probably fit the other side to keep the details correct ::)
