I could send you a parts diagram and some pictures if they would be of any use for inspiration? I am following your thread in awe... I am not brave enough to start a machine build from scratch, but you seem to be doing just fine Peter |

As for building the machine I just kept bits for ages before starting then jumped in two footed, I have made mistakes even in the very little I have done so far wait till you see the latest one which I will take pics of tomorrow actually not tomorrow me and wife are going to see mrs browns boys so saturday its a real :doh: |

Well here in pic1 is the latest mistake It wasnt till I had welded the flang on, cleaned it up and centered each side that I set it up and did a cut along the length and I noticed it had been cut half way through :doh: cant even remember what I started to cut it for. Well went back to my bits of steel and started again and pic 2 is the result. I am very pleased with it this is the first time I have cut a thread and made nuts to suit which is where I was at the end of today and apart from my parting tool of sorts breaking part way through meaning I had to finish it on the donkey saw even this went reasonably well. I still have to clean up the nut and cut the lock nut off the bar which is the job for tomorrow. |
