Provost - Part 2

Kevin asks for a

hard core manual

Kevin, if you got hold of an instruction book like that the next thing you'd need to do would be to borrow Brian's chastity belt.

I wouldn't have the first idea how you go about machining something like that, but I can appreciate the skill involved, I wish you'd done a time-lapse video of all the different processes involved.

The following pics should provide an insight. X & Y axis via the normal milling machine slides Z axis from the headstock used in conjunction with a tilting rotary table. So managing 5 axis with my ageing brain didn't leave any capacity for recording./ photos

Making the forks :-
1. Diagonal section of stainless tube - later heated and reshaped.
2. & 3 Machining the saddle
4. Silver brazing the parts (yes Chris 001 i make jigs as well )
5. initial clean up

Fantastic machining Kevin. I am jealous of your workshop and your dedication to making such detailed parts. I appreciate how much effort it take to plan the 'cuts' for such precise components and I am humbled as I remember how much effort it took to making simple vices, clamps, andother stuff when I was an apprentice.

Awesome work Kevin, I'm sure the master upstairs will give you his approval..
If i can be of any help, give me a shout Kevin..

Tailwheel now complete . Doesn’t look like much extra but was actually double that in my first post due two attempts on the steering tiller and a complete rethink on the suspension which has increased weight to 100 gm (4ozs) but should be OK with an estimated AUW ITRO 20 lbs
last two shots - Because the tiller swings when the suspension is compressed, the closed loop connection has to pitch and the wires require some method of spring compensation so made this mock up to prove everything
