What about photoshop ;) Nobody would have noticed....

Hi Paul, I don't fully understand this and may be completely wrong. I am interested so trying to work it out in my own head. Assuming your interest is genuine this is my thinking on the matter - which may be completely wrong :) Bicycle and cars have similar issues to overcome. High torque is...

Of course if you want to turn really big things try this: http://lumberjocks.com/topics/5901 - scroll down a bit.... BM

Done a bit more reading - my son is interested as he is doing an engineering course. It seams that torque drop off starts at 8% of motor speed for simple v/hz inverters and improves down to 2% for open loop vector inverters and 0% for closed loop vector inverters. No idea what type of inverter...

Not wanting to go too far off topic but the question of torque fall off at low RPM interests me. This is my understanding but I may be completely wrong so please don't shoot me down. My understanding is that the torque does not fall off appreciably until the RPMs get very low. As the frequency...

Greg, I think on the new lathe I would have gone with a similar design as yours if starting from today and not having experience of how well the stationary beer line works. One thing to remember when you switch to a low volume, high pressure approach is that even small leaks can vastly reduce...

You are not missing anything - and I started with the same concern. I have not seen any others using the same design as mine before, as you say most have the rotary coupling on the tail stock side. My old lathe had a hollow spindle with a cross drilled spindle lock right through meaning it could...

Hi, Not my area of expertise at all but I will have a go :) A 415v 3 phase is usually configured in a 'star' config. It may be possible to change to a 'delta' config by changing wires in the terminal box. Not all motors can be easily configured as delta as the necessary connections may be...

I think I would have the Jet but both out of my price range so not looked really close at either. BM

Had a bit of nightmare day so no photos. I did make a new 4" chuck and used two bearing this time and got 19 inches of mercury so a big improvement. I actually made 2 4 inch chucks - screwed the first one up with a silly mistake - didn't let the glue gun heat up properly and the fumbled feeding...

It should get posted today. It is a slightly different length than the original but still fits as the motor can be adjusted backwards and forwards about an inch. The original spec belt is no longer available. A helpful man at Poolewood pointed me in the right direction. If you search the...

Bob, I think you are right, if you make some ad-hoc sales and declare the income then you should be fine. The Inland Revenue will want you to become a sole trader when ad-hoc becomes regular income. Sadly there is no real definition of when this is but as I was doing monthly craft fairs my...

Thanks Nick, Still have not done any research so here goes for the first dumb question - you will soon see I have absolutely no idea what I am talking about...and I am sure I am getting ahead of myself. If I want a part wood, part resin item such as a piece of wood with large voids filled with...

I am also interested in this. I need to do some research first before I ask too many really stupid questions. I do have a vacuum pump and a vac chamber sounds easy enough to come by. Thinking half a propane cylinder with a thick lid and gasket? BM

If you are holding out for an OEM large turning attachment you 'may' get lucky but I expect you are in for a long wait. This means DIY is your best bet or buy a fee standing rest such as the Jet one sold by Axminster. I have only seen one DIY attempt on the 28-40 and that is mine. I am sure...

Hi Robbo, The components are: Stem - 1" mild steel to fit my banjo - cut at an angle. Body - 60mm x 6mm flat hot rolled mild steel - this is bent to whatever the angle is in the flypress and then stick welded on the stem. Edge - 6mm stainless steel rod epoxy glued to the top of the body The...

Not a problem. I would definitely recommend using a vacuum gauge in the setup - easy to test if you have a leak. Vacuum gauges come in a variety of units, I choose inches of mercury for some reason I can't recall. I can take some photos tomorrow of the rest of the setup and give you some...

PM sent.

Agree, for me it is essentially a hobby - I sell turned objects and blacksmith items, but due to poor health and having an almost full time job I can't realistically pursue it as a viable profit making business currently - I don't have the time and energy to pursue it. Still, I sell at a number...

Pete, you are right to point that out. Trouble is that this is a bit of a difficult and gray area as I understand it - and I don't understand it that well so please double check anything I write:) I am married to a chartered accountant though and she has skimmed my post before I submitted it...
