|Thread: Lathe run out|
Alignment bars from India - yes it does depend.
I took a chance and paid £80 for an MT5 one with Express delivery (Arrived in 5 days)!
There seemed to be several suppliers and I was lucky.
Mine measured OK and the results matched those done by a professional, with an ex Harrison works real thing, on my M300 the week before.
My only criticism would be the lack of proper centers in each end, but still worth the money I think.
|Thread: Fiber change gears|
Sorry Gentlemen it,s the fiber gear I am more concerned about. It came from 600 group as it was an original gear but missing from my S/H machine.
For the price I expected a metal one....silly me! and then the lubrication advice in the manual would make sense and be followed.
When I get it up and running I will have a change gear set on my Harrison M300 that will comprise a combination of metal, fiber and Delrin gears.
Do I lubricate the set, and if I do, what do you more experienced machinists suggest I use.
I seem to remember reading somewhere that nylon should not be lubricated, is Delrin the same?
|Thread: Harrison M300 single phase from new|
Thanks Gentlemen, very quick replys.
I did originally think it was a one off until I read the post by Tony on lathes UK fully, then realised it was, maybe, a desire by Harisson to make a lathe that could be plugged straight in to a normal (in the old days) 15A spur.
My question should have been phrased more towards the headstock than the power supplying it. I have done three VFD conversions so am happy with that it is more "are all M300 headstocks created equal".
Was it reasonable to assume that it would make no sense for them to build a more fragile gearbox for a limited run 1ph machine. Can I safely double the power I put in. I guess the designers are no longer with us so we can only make an educated guess. The slower motor and a slightly smaller drive pulley would halve the input speed, and therefore spindle speed, without having to change anything in the headstock.
Clive, I will look into your drive suggestion with the "backgear", that maybe is all I need. I bought the M300 manual and noticed the 110v switching system that I could well do without. Give me a VFD control circuit with 24v @ 50ma any day.
Thanks again all,
Has anyone had any experience with a single phase M300?
I am considering buying one that has had an easy life by the looks of things.
The motor is only 1.1kw, half the usual and the speeds halved as a result.
I am guessing the only difference is a slower motor (960 on the plate) and different belt pulleys, the headstock being standard.
A new motor and VFD should give me back the normal speeds.
Have I missed something ?
|Thread: Snooker Que thread size|
I have been asked to make an extension to a friend's snooker que.
One end requires a standard UNC thread, the other, this one.
The que, at this point, is a little over 1" dia., the thread measures 0.362" OD, 12 TPI sort of matches. maybe 13!
ACME threads of 3/8" dia are 10 TPI seemingly (not that I have had anything to do with this type of thread).
Any ideas anyone?
