very nicely done I wish I had those skills |
| Darren:
Thanks for the kind comments chaps. Who said skill? Wrong place for that, I'm only learning and bumbling along as I go. John, I'd be interested in how that misting unit gets on when you have it sorted. I did use WD40 on this, but that's not the same is it. I would have done more tonight, but I'm in too much pain this evening to go into the workshop. I'd have a job to walk there never mind stand at the machines for an hour or so. It comes an goes, old bike injury, lost my right hip about 20yrs ago. Completely shattered it, was too young for a hip replacement apparently. Can't do it till you have stopped growing. It was either leg off or make do with a badly repaired hip, if you could call it even that. I chose the latter, like you would.... Anyways, I'm rambling no, must be getting old or sumut..... :ddb: :ddb: :ddb: |

Moving on a little today, time to make some more parts to go with this. Starting with the cam I used a piece of 30mm alloy bar. Turned it to 27mm the same as the bore in the main block. I chose 27mm because a have collet in this size. See, I've started doing some forward thinking at long last !! :lol: Next task was to machine an off center cam for operating the piston. A distance of 2mm was chosen which happened to be the size of this piece of scrap. So it was used to measure the offset. That's the cam done Turned it around and stuck it in that 27mm collet I mentioned earlier to machine the head. Off to the miller to drill and tap for a handle, I chose a 6mm thread. Now we need a center spigot. Selected a 20mm bar for this and duly turned it down on the lathe. This fits down the center of the cam and is slightly longer, half mm would do. This allows the main block to be tightened down without pinching the cam unit. Next up is the piston, nothing fancy, it's just a small slug. Mine has a hole down the center simple cos it was already in the piece of scrap chosen. It could do with a couple of o-rings to hold it in the main block to stop it falling out. I'll get to that when I can find some and put a couple of locating groves in the piston to hold them in place. Sum of parts so far, used a 6mm bolt for a handle for now till I make something better. |
