Remember you Steve.... Still in awe of your water pressure engine!!!!! :jaw:
Too cold! How cold is it? .... Bout 3-5'C here.... I spend the winter in the shop and the spring/summer out enjoying myself ;D
Hopefully he will get through his issues and carry on designing/building these fun little artworks.
I'll look forward to the new projects in the spring.... until then feel free to comment all you like on my stuff :thumbup:
Ralph.

Remember me?....LOL. I'm the guy who builds em without drawings. I completely understand the desire to work through the idea.
To my surprise, Karsten did get at least part of out latest order to us this morning. I'm not sure what specific issues he's dealing with, but I certainly do worry about him.
I'm not doing much in the shop, at the moment. Cold weather has begun to shorten my stay out there. I'll probably spend the cold months indoors, lining up projects for this spring.
Thanks for the warm welcome
Steve

Right then! A bit less of this :offtopic: ( :D ) and a bit more on the Aeolipile....
Tonights (well this mornings too!!) offering...... The start of the cutting tool to make the die.
To start with, a piece of 1/2" gauge plate (from an anonymous benefactor :wave: ) is cut into an approx 55mm square (approx because it was cut with a hacksaw!) This photo taken on a break 'cause I was knackered!!!... Supprised it's not blurred with the heavy breathing going on!
A hole was then drilled through the centre to allow the use of an arbour (8mm with an M8 thread on the end).
Once all that was done the corners were removed with the hacksaw and then the turning to exact size could begin.
The blank is left at 51mm dia' to be sized correctly in the next step.
The compound slide is then altered to 3' (from here on ' is the symbol for degrees). The blank is now turned to size using the compound to create the cutting angle required.
Next, the holder for the cutter as started from a piece of 25mm stainless I had in stock.
First turn the shank to 16mm (the largest collet I have for my mill)
Then holding the part in the rotary table, it is centered and the RT set to 0' (important to know this for later) and a slot is cut 35mm deep.
a test fit....Sorry about the blur!
The RT is then turned on it's side and the work piece rotated 90' to allow for drilling. the first hole is for the main locating pin to go through the centre hole in the cutter (8mm) The offcut of gauge plate is used to help minimize any flex when drilling.
The pin inserted. the top hole for the clamping screw can now be drilled. The first hole is through all parts with the 4.3mm tapping drill. Then 5.1mm clearance drill through the top hole of the holder and cutter stopping short of the lower hole that is to be tapped M5. A recess for the 8mm head of the screw is added to allow the head to be sunk but still clamp the cutter.
The part is rotated 180' and the holes tapped M5x.8
The screws are added, the top one a standard M5x20 stainless cap head. The lower one is modified to make it's body 8mm dia and be used as the locating pin.
(might have to re-engineer this bit so it clamps aswell?.... Probably best!?)
So then what you have is a close to finished tool.... Just needs hardening and tempering and a little jiggery pokery with a file for relief on the non cutting side.... Might try all that today?
Any comments like "there is a much easier way" will not be taken totally to heart.... I'm happy so far :D
Ralph.
Darren:
I'm intrigued in what you are going to do with this cutter? At first i thought you where making a 50mm sheet metal hole cutter, (which could have lent you)
But it seems not....this must be for something else...shall watch with interest... :dremel:
CrewCab:
WOW :headbang: .............. I see the "classes" are paying off; better get mi'self booked in :thumbup:
Seriously .......... nice engineering Ralph ............ keep it coming.
