Stuff you have fixed today

[plantlife]

The little plastic shelving unit looks likes it’s holding a bit of weight too!

 

[Robotstar5]

I know nothing about that, but might bé able to heip.

I must have confused you with someone else on here , I thought you worked on boats.

They seem to be coping better, probably because they are narrower and I can't fit too many engines on them.

 

[Brad93]

Is it fixable?

This just cost me £215 for the lathe.

it's fixable if you know a rewinder

I don't know a rewinder. But i do know a new motor supplier.

 

[The_Yellow_Ardvark]

A recent donation.

We have already rewired the drill and got it working.

But this happened.

Not impressed.


But I found this.

Well, uncovered it in the mess.

Nice simple fix.

I fixed the toilet flush handle that snapped yesterday. A new cheap one from Toolstation, five minutes and job done. So satisfying to fix something first attempt after weeks messing around with the Fiat 500
No pictures as it's just a bog flush handle!

Rears today, first a check I had the correct tool to get the hub off. Bought years ago for an A3, it fits.

Taking the rear caliper off is a pita on the golf with electric parking brake, diagnostics tools required so I decided to try to take the brakes and disk off together without releasing the parking brake.

Held on with two bolts.

The whole lot came off together and got tied up. On to the very tight hub bolt..

Looks like the heat shield is held on with the stub axle bolts.

Old shield off.

New one back on.

Bolted back up and on to the other side. Both sides done in ~ 90 minutes.

I did rear on the the missus Mk7 Golf this year, what a faff.....simple 2 piece plate would save hours of work

 

[prepman]

Re-modelled the plastic hinge for my Summit folding chair....hours of work and printing to repair a £25 chair...hey hoo! Mainly due to mis-placing Prusaslicer and Repetier Host configuration files over the years.

My NATO Marching Compass ( 6605-99-531-250 ) has sat in a drawer for decades - mainly as it had a large air bubble in the damping fluid. I did pull it apart decades ago and top it up but eventually it again developed a big bubble.

Well now we have Goggle I unleashed a suitable search to find that this model was only made for about a month AS IT DEVELOPED BUBBLES

I thought I'd have another crack at it today - eventually got it apart - taking out far more screws than were necessary, and topped it up got it back together. Apart from the fact that it's outer (none sealing) glass is cracked and the rubber base ring is a bit perished it's back in working order - for now at least.

So - all you have to do is gently lever off the brass rotating bezel (the bit where my glass is cracked), remove eight underlying screws and lift the sealing cover glass off. Gently lift out the mother of pearl magnetic card from its pivot, top up the fluid (I use cigarette lighter fluid) to form an upwards bulging meniscus, replace the card, again top up to an upwards meniscus, and re-fit the cover glass and eight screws without introducing air bubbles. Below the pivot assembly is a bellows, so as the glass cover is pressed home the excess volume compresses the bellows and with any luck you are good to go.

The brass bezel is retained by a spring clip that sits in a suitable groove in the brass and in the body of the compass - same system as is used for DTI's face glasses.

No during' pictures - I forgot - but here it is finished.

If anyone has a spare rotating brass bezelled outer glass please get in touch

 

[Brad93]

Have a question associated with this.
Regarding part circled in red. Say if I wanted 100 of these pressed out. What would I be looking at for unit cost roughly and tooling?

£1000+ for the tool

Dont you have to cool the case before filling to get the Bellows contracted

 

[minimutly]

£1000+ for the tool

Hot pressing?

 

[Barking Mat]

I know nothing about that, but might bé able to heip.

If I remember correctly (?), it was an engine driven deck washdown pump, of which I have zero experience, we have a bloke who washes our boats, he's great.

Got this pretty sorry mini Sheffield sheath knife from a junk shop. It was all loose a r someone had had a go peening the end of the tang.took it apart straightened it welded an m4 screw io the end of the tang. Made a threaded brass bead reassembled and cleaned it up

Just needs a sheath now.

Aye my photography leaves a bit to be desired

£1000+ for the tool

And the rest! That's a pretty deep part, it would need progressive stamping so you're essentially buying several tools in one. You've got to pay someone to develop it, manufacture the tool, probably manufacture a second one when the first version cuts undersize, and finally pay someone to press them out (A day to set it up on the press + 2 minutes to make 100 parts). I think you'd be doing well if you got the tool made under £10k.



100 is an awkward quantity to make. Less than 10 it might be viable to turn them from solid (Or cored bar), or fabricate them. 1000+ it starts to become worth getting a stamping tool made.

I'd consider approaching the supplier of the drive shafts and seeing if they can sell you just that bit.

A tool that simple isn't going to be more than a £1000 - he wants to make 100, not a thousand parts. Now if you said it needed to make 100 parts a year for the next 10 years you might look into commerically made dies of fancy tool steel and grinding it to dimension. A bog standard tool steel with a turned finish then polished will work.

At the end of the day that part can be pressed out in a workshop hydraulic press, its basically tin and probably of no great tolerance either given that it looks to be a shield for an axle.

Personally I'd heat the blank with a rose bud, plenty of this on the die & tool https://www.anvilfire.com/prod-docs/Forge-Ease-3512-info.pdf
Would have to be hydraulic press with a fast action, to limit the amount of heat lost to the tool/die.

 

[Brad93]

That's annoying. Any cheaper routes?

Metal spinning. Still over £2000 for the job i reckon. Die would be £500 minimum.

£20/part sounds about right to me.
