New B head.

Since my pattern cutting machine just cleared time I decided to start cutting the pattern for the new B head today. Also got my new Mazak horizontal soft wired and powered up to see what things look like.

A lot of glare on the screen due to light from outside but the monitor is clean and clear in real life. This is very good.

We always open up the Z axis cover and set our best level on the guide. If you have two precision levels one on Z and the other on X it helps to get it earth leveled. By the pic, it looks like you were able to get it homed out ok. But I see an E-stop.

I assume its a 40 taper? Did you try a tool change? If its loud don't start running it yet.
Can you post a far away pic of the machine?

3 bolt pump. The chamber will be like a Winfield crow's foot with stock location plug.

Will do. Today I finished the rough cutting of the pattern and started on the finish pass. Looks good so far.

The Darton sleeves came in for the first two aluminum blocks and they look great as you expect Darton sleeves to look. Checked out dimensionally so now I need to get them installed.

Rough cutting the pattern.

And... the sleeves for the first 2 aluminum blocks got here.

Hey Tod,
Thanks for the pictures. That is one nice looking head :) !
And, the sleeves look like jewelry ...for engine lovers !!
Now, after seeing sleeve pictures, I think that images answer a question that I was curious to know answer of...i.e.- how are sleeves 'anchored' to block ? Does that ledge go on top of block, where head actually helps keep it in place :confused:

The main anchoring is done by metal crush on the OD of the sleeves. There is usually a couple thousandths of crush on the sleeves. The block is heated and it expands so that the sleeves slide in and when the block cools it squeezes the sleeves. The flange on top helps insure that it cannot possibly rise due to the head being torqued down on the sleeves.

Today the finish pass on the B head pattern was completed. It sure looks nice. I made it out of wood because I don't expect sales of this head to be very high. And, I probably will put a "C" on it as the originals have.

Hey Tod,
Thanks for details of installation ! I like the idea of the head locking the sleeve down. I think that's one modern method used for that purpose.

I happen to have a C head lying nearby in the shed, if you need a picture of exactly where that C is located. If needed, let me know and I'll PM you a picture.

Why don't you post the picture here also as well as PM'ing it. There may be a couple of versions of the head as time went on. Any chance you could explain how to attach a picture to a PM? I haven't been able to do it.
