Guys,
My first real project, born out of necessity. Its a propshaft / tailshaft extension off a 1955 Land Rover and is to be turned from a 100mm DIA 1045 steel and is about 100mm long (my stock is currently about 120mm).
Im thinking the following methodology but am guessing really. Id really appreciate some advice on what to change below or a correct description on how to end up with the item and not a whole load of swarf and bits in the scrap bin!
My thinking...
1. In 3 jaw, face the end and turn over 50% of its length to round
2. Turn around and put in 4 jaw - indicate to centre.
3. Face the end and turn remaining length to same diameter as bit already round.
4. Centre drill and then drill progressively larger holes right through and bore out (to approx 30mm but its not a critical diameter).
5. Face off the edge to get down to 100mm length
6. With LH tool, cut away to form right hand flange
7. With RH tool, cut away as much as possible to begin forming left hand flange.
8. Lightly mark PCD for 4 bolt holes on outside edge of right hand flange.
9. Remove from 4 jaw, turn around & chuck up on flange and re-centre with indicator.
10. Form Left hand flange
11. Lightly mark PCD for 4 bolt holes on outside edge of right hand flange.
12. Remove from lathe, mark out 8 bolt holes and drill in Drill press
Any help greatly appreciated.
