I am making a small engine cylinder head on a "Micro" lathe.
I am working of a domed recess in the main chamber, which is the squish area of a two-stroke.
I found that if I come straight in from the front side, then cut towards the centre,
I need zero top rake, a fair bit of front rake, and a...
I can't find these on Google.
What are they sold as?
I saw one once on line.
they have many hole of different sizes in a hardened steel plate.
hole sizes 2mm to 10mm
This is handy for making small engine parts.
The objective is to simply clamp the plate in place and drill through a hole.
The Quadcopter design, without the cyclic pitch control, seems to develop massive bending torques at the rotor head mount, when cruising at speed. (5m rotor) I looked at some helicopter shaft-rotor join detail drawings on Pinterest, and they seem much lighter built.
Has anyone seen drawings for...
Aviation-rated reduction gearboxes 10:1 55 kw prop mounting.
I need to find an appropriate company that does this. I found a good one for motors and controllers, but they don't do gearmotors.
I suspect industrial gearbox makers don't want their products used for this.
There is about 6 kN pull...
This question seems to be forbidden on most other forums.
I cannot get any sense out of Google. please help!
High speed, high power alternators don't seem to come up.
I don't know why, they are used on micro-turbine gen sets, so someone must make them???
I am looking for design info for an annulus spring to act as a friction drag between the inner and outer shell. Radius is 21mm, torque wanted is 0.7 N-m initially.
width is 3.5 mm , annulus height is 2mm.
By initial fit estimates cof as 0.05, grease packed. Net force = 700 N, drag force = 35 N...
