What line of work does your company do to need a microscope. Nice score.

[plunger]

Wow . Thats all I can say.

[plunger]

I did a stress test using a piece of cast iron to simulate the block. The torque sequence is 25 newton meter followed by 60 degrees x3. I did not have...

I soppose if I used an m12 x 1,25 mm homemade insert I could time them. If I tapped M10x1,25mm and them put a head bolt in the hole ,theoretically if...

Sorry bad maths. Its R16,5 to the dollar.I have found an engineering supply only 6o kms away that has and at half the price. But its only for a ten mm...

Thats five hundred dollers and 25 days shipping . You would be lucky if you get it because of our post. And it looks very chinesee.I will just try it...

[plunger]

Thankyou Mike . Doesnt look so bad. . We have put the head on and its been torqued down to 25NM and three turns of sixty degrees . It seemed...

[plunger]

The thread still takes so Im going to try see if it will hold the torque .Dr mike has some impressive skills with cad. I wonder how a cut out super imposed...

I will come clean and tell you guys what a monumental ballsup I made. My opel cylinder head blew. The block is cast iron and the head alu. It has m10...

[plunger]

Damn .That is so useful to be able to do that to see whats going on.I doubt it will be easy to get a tap of m12 x,75 or even 1mm. I wonder if a homemade...

[plunger]

fThe m10 x 1,25mm is the size for the headbolts which cannot be changed . I dont know how close 14mm tap will be to the water jackets. I also dont have...

[plunger]

Im terrible at math. Thanks for the reply. So the wall thicknesses just wont be sufficient. I wonder If I used a m12 x1,25mm fine thread or that terrible...

[plunger]

I have a a cast iron block that needs the headbolts threads repaired. I dont have any helicoil insert tools and here in Africa m10x 1,25 mm is an odd...

[plunger]

I wish I took a pic of this machine shop. There was so much oil in the driveway from years of work it was like mud. It was like out of an apocolypse movie....

[plunger]

Thirty years ago in a past lifetime I used to do alot of this as an apprentice .I was doing my time in one of the biggest toolrooms in Africa. I was working...

[plunger]

Your camera is seeing double. That is very pretty....

[plunger]

Using a one meter rular as a straight edge I can put a 0,2mm feeler guage under it in some areas. Its not precision but precision enough to tell me its...

[plunger]

Do you believe him . Hows the the old saying go.
Curious to know what they look like

[plunger]

When I block things up i notice I am about 0.05mm out . But this is over about 80mm. I dont have any straight edge or flat surface. I also didnt quite...
