A block? what material? hw much welding?

A tig setup for steel is a LOT cheaper than for ally, in fact it is possible to use an arc welder box to weld steel with a tig torch and argon.

But to answer your questions,

a, yes within reason. its fairly easy to get the basics but to get good is another thing!! if you can mig, arc or gas weld then you should be able to get the hang a lot quicker.

b, really its down to practice and expirience, instuction will be more in the form of pointers and advice.

c, never seen tigs for hire personally, but i guess some one must rent them out.

d, yes, a block asuming it is a weldable material may well distort when welded.

BOC hire places usually have welding equipment for trial in a trial room, i'd go down and pretent to be interested and rob a go on a tig set!

Welding of block for plugs for 16v k head conversion so not loads.

just thinking really.

I thought the normal practice was to locktite them in?

Make the plugs from cast iron bar and make them an interference fit. If your really concerned then loctite them in!!!

I'd not want to weld the block top surface!!!!

Every day is a school day ...........

How fast and how expensive ...... the same question...

when i had a bras plug move in the head i used a 7 degree taper ream thingy (handy for cleaning up balljoint taper holes) to make a tapered hole and pressed in some tapered plugs with plenty of loctite, I f i were to do a block i'd adopt this approach. The reamer was only about a tenner.

Good call....... I'd probably leave the plugs a fraction proud so that they'd be taken down easily when the block was flashed ..

the reamer i have looks like this,

probably even better would be this,

a no1 morse taper is 1°25'43"

sad ain't I!

I thought the magic number for a taper was 14 degrees

ahh, do you mean the balljoints?

that would be right, when i did the plugs i had to set the lathe to 7 deg but of course there's 2 sides.....

Well i said 14 degrees cos thats what we use on the plugs for shell and tube heat exchangers used under pressures up to 300psi

As for cast iron welding, im sure ive seen some one do this, heads have also been welded, BUT, it wont work for long

Its either metal stitch or fusion weld with a kiln

you can weld cast iron, you need a nickel based rod if i remember correctly? Possibly even a flux of some sort? We did a block at an old work place of mine, some rare austin healey one.

Then again i may be talking jibberish!

I think strength is an issue when using ordinary methods of welding.

I welded up a set of cooper S calipers after the bleed nipple broke. :/

You sure can weld cast iron, nickle rod and arc welder. Not sure about flux as when I have done it I use rods made specifically for the job.

My concern would be that the welded block surface would be a pain to machine flat properly. Mill then Grind should do it but I'm not aware of many places near me that could do a decent job of grinding a block deck so ...

I can do it on my grinder. Its accurate too :)

I don't know why you have the idea that the block has to be welded??? No-one else has had to weld a block, so not sure why you see the need?

Sorry i miss read something in the guide book.

i htought the plugs were welding in place they are not. oops

my mistake.

I think some one on here did weld them in, and grind them back, can't be sure though as i can't find the post.

Ive deffinatly see people weld them in too.

wrong fecking thread.

I have started posting on Instagram also my name on there is turbomk1golf

Nothing is impossible it just costs more and takes longer.
