Any machinists int house or modellers?

My old man has a lathe will ask him tomorrow what material??

i reckon brass wud be best, but maybe steel wud be cheaper to trial?

 

[jai_landrover]

I'm sure we can do steel would be easier alot of wasted material from one lump of brass and not cheap material. With steel you could weld the boss in and machine the weld down smooth.

bit intricate for a 6 x 16 boss!

25mm round bar, turn the boss, part it off. turn it round, wap the hole thru, countersink the face. start agin.

when mhm decides eggsackerly what he wants.......

 

[jai_landrover]

I have some phospher bronze (for diff pegging) if its 25mm its roughly that dia I'll happily turn one up for you as a pattern see if it would work and then you can get the material you need

thanks guys.

Any help appreciated.

 

[jai_landrover]

not too bad we weld alot of stuff and put it on the lathe for our model aeroplanes.

Bar is better tho

Why would'ja wanna watch virgos?

You disgust me!

a bit like this.....

the holet o be 6mm (I think) recessed on the other side to allow a 6mm csk screw head to be flush with outside ( or a slim nut).

I had thought of the brass one above with an O ring as a tyre.

The large dia is 25mm by 4mm thick. the boss is not critical to the best of my knowledge - anyhere up to about 16mm dia, i reckon.

i just may have something like that in the shox box,the mountain bike has all sorts of bits like that,i can look in the box in the morning.

steam or stirling?

 

[johnny curt 1]

steam or stirling?

single valve shunt seal 2 stroke steam ( copy of a single cylinder horisontal gas engine ) ive also got plans to make the same engine in 4 stroke and if i can find the right bearings ( VCR head unit ballraces ) i could possibly make it hit n miss

got another i made from **** like brake slave cylinder and skateboard bearings n a few plumbing fixtures

 

[jai_landrover]
