New part in carlock

[Torbo]

The doorlock broke in my car. - Volvo Duett 66.
A fether was broken, an the square hole was bad.


I lathet a steelbit to 14,5 mm outside and 8 mm intside.
And I took an old tread tap to make a new special tool.
The process:

Glued a alubit square to get right angels.
Grinding and grinding.

Then cutter some "hack" with mine angel grinder.
I took it in the press, but i dit not get it trough, so I took a big hammer to get the rest. The new tool broke, but the hole get perfect. Just a lithe bitt filing at last.
Good cases...

Match:


On place. i right direction. Welded it with castrolin-case. Bronshe?


New fether and i worked well:

Good deal. So you made the tap into a broach or punch?

 

[Torbo]

Thats right. Tap into a broach or punch. It worked well, but it required very large force to the tool through. Possible it had gone better if I had centered the part in a wise while I squeezed into the tool. it was not so easy to pass.

May be it is nom at bad idee?

The square aluminumplate was a good idea anyway, I think?

 

[chuckorlando]

Brother if it worked, seems to me it was a great idea.

Thanks for comment!
I worked, yes, but it was hard to get the tool trough the 8 mm hole. The peace was 12 mm long, because I should make to parts in the same operation.
så I cut it an have on to the other door, if necessary?

It have may be more easy to make to separate parts?

May be I small try that?

There is may be other that can use the same policy?
(normal failure in old Volvos)

After grinding, I forgot this picture.

That's a good fate for an old tap! And I am glad to see a Duett kept on the road- they are not common in the US even if we have plenty of 444s and 544s.

The same thing in Norway and Sweden! They are hard to get, most of them is destroyed! Mine is in very good condition!

Yesterday a Make a rotary broach like this:
Ok, bot not perfect. I will put on some roller bearing I think.
Hard job in steel, but in bronche it worked well.


The first self made tool worked best!
