I though I would post up some step by step pic of a pair of heads I am making.

They might be of interest to the 2 stroke suzuki owners

Basic setup in the mill to drill the hold down bolt holes and centre hole for insert



Boring centre hole



Flycutting top face

Squaring up the sides

[ball]

I had a chance to get back to my heads today.

Roughing out the insert pocket




Drilling water galleries




Slotting water galleries




More tomorrow hopefully

[steak_knife]

nice, watching a block turn into a head

[ball]

There are going to be 2 of them. They are prototypes for a formula 500 speedway engine.

For my next trick I am going to carve out a crankcase, cylinder and more heads for a drag bike, but that won't be until next year. I am still undecided on the configuration I want.

[steak_knife]

Are you making the entire eng? I have had the privilege of seeing a crank made from billet, only because I told him he couldn't do it

Most of it.

Some parts just aren't worth the hassle to make and it's cheaper/easier to buy them.

Pistons, rings, conrods, valve springs and any bearings will be purchased. I will probably buy the valves as blanks and turn them up to my specs. The crankcase, cylinder and the head(s) I will carve from billet.

The crank isn't a problem. I will rough it out, send it for heat treating and have someone finish grind it for me unless I get my hands on a crank grinder before then.

I want to go with 4 cylinder as they seem to be the fastest on the track at the moment. All the V twins are struggling to run the numbers.

2.2ltr four with front mount supercharger but with desmo valve train.
bet ya cant make it.

Why stop at 2.2ltr ????

[shep]

cos that leaves room for making it bigger . plus you wont ride it and i might
get worried if it is too big.

[dave]

Lets be truthful you are already scared of it. lol

so......whats happening.

Picked up some inserts for my boring bar in Darwin last week and will probably get back to them tomorrow.

I spent today fixing a poxy caravan that had it's wheels hanging off due to piss poor maintenance

Just out of interest what inserts are you using Ball?

[shep]

damo if he got them in Darwin they are probably hairyforbs Chinese jobbies.

[ball]

Yep they are from hairy forbes, the brand is vandurit. Never tried these ones before and was all I could get on short notice. I will let you know if they are garbage.

All my lathe tooling is decent kennametal gear, just some of the mill tooling is chinese.

I have a couple of chinese made endmills with inserts in them and they are brilliant on the manual mill. I don't think they would hold up on a machining centre though.

[Damo]

Good to know you're getting some decent results with Chinese stuff, as that's probably all I can afford!

The inserts I just got were pretty much the same price as the quality ones I know work well

Goodwork Ball.

I can make many things. But not main components!

[BUZOOKA]

im a deli bitch get it right lol

[jimbo_jones]

thats some good work ball when its do are you going to strap a rocket to it it might make all the diffrence

[ball]

Work has come to a halt on the heads. I want to turn the inserts up next but I need my big lathe back together.

I will post up some pics of the bits I have been making to rebuild the electronic side of it tomorrow.

I can also use the lathe to make more rocket engine casings and my dirty great big hybrid rocket engine
