I have a Harrison L5A lathe (1964). I have a persistent oil leak from the headstock main shaft just aft of the chuck. I have got a complete original handbook for the machine and looked at the exploded view of the chuck to see what sort of an oil seal I should replace. It does not appear that there is one?

Also looking through the handbook I can see no detail on what the headstock oil capacity is and where the drain is for draining the headstock if this is required.

All I can find is that the oil should be Shell Vitrea 72 or equivalent. This is a lot thicker that what I am using which might be part of my leakage problem?

Thanks again for all the posts, particulalrly those with links. From this I can see the George Thomas capacities are too light for what I want. have found other design

Thanks

Hi, thanks for those 3 replies. I have since googled the GHT Model Engineers Workshop and the cost is a bit steep for me (I have quite a few of the workshop series already). What I would really like is a way to access and pay for the model engineers series 3456 and 3457 only , preferably online without having to pay for an annual subscription. Is this possible plse?

Hi, I am looking to make some sheetmetal rollers. I have seen several designs including one described over two recent MEW issues. However a recent article in issue 241 entitled "Exhaust cones" shows a photo and reference to an early geared type by G.H.Thomas. Can someone please tell me what issue (if any) of MEW plans for this type is shown in. I particularly like the under rollers are adjustable as I am hoping that I can get quite wide range of diameters rolled from them.

I have drawn a scale drawing of 40mm dia rollers out on paper and from what i can see will get quite quite small diameters from a top adjusting roller type. I would like to be able to roll up to 400mm rings if possible
