Accepting the limitations on resolution/surface finish, some of the ideas I have had include:

• Drumstick holder
• Custom cable tidies/clips
• Custom project cases
• Telephone/multimeter/instrument holders
• Temporary jigs for balsa models etc. (e.g. holding wing ribs upright)
• Semi-finished parts for automatic rain gauge
• Caddies for rechargeable batteries

Not an earth-shattering list, by any standards.

Surely for sandcasting moulds, you could use hollow patterns?

Hi Martin, for some reason I don't see one side of each spoke

Thanks

Neil

It cheers my Imperial sensitivities to see so many 'up to date' metric head advocating the long-deprecated cubic centimetre!

Google's Picassa will rotate videos for viewing but not save them in the new format.

I think the (excellent but tricky to get the best out of) Pazera free video converter will allow you to rotate videos.b It also converts GP3 phone videos and quicktime ones to a windows friendly format.

I vaguely recall only slitting one side of the eccentric, so it could be tightened up to compensate for wear (as if it will ever be run for THAT long!) I'll go and check...

...indeed that IS what I did. The cut is dead square and very neat - I am totally bewildered how I could have made such a good job of it without a very thin slitting saw. I can only think I used a razor saw and ran it along the top of the vice?

If only the rest of the thing was as well made - it was my first 'proper' attempt at model engineering!

Neil

Thanks John,

After this DIY all gets done I plan to get back in the workshop and make a smaller drive gear and go back and conquer the1 in 10 track at Derby

If anyone would like a look at the plans as they are now (comments welcome) just send me a PM

Neil

I hate it when people's jigs and fixtures look better than my finished work...

Neil

Hello Gordon,

Looking at your second picture, there's quite a large 'step' at the top of the test piece which suggests to me that you are taking quite a hefty cut. Is it possible you are driving the shaper a bit too hard?

Neil

I hate Dalo poens ... but what did I do today?

> kitchen table

Well if that is eligible can I mention that I tiled the kitchen? At least the 18" above the worktops, with the exception of finishing round the plug sockets. £4.20 for 8 50mm socket-fixing screws - I should have made my owm actually i [probably will need to make 2 as one socket is now 3/4" further out from the wall - whoever built our kitchen extension did not work to ME standards of squareness and accuracy!

Happy New Year to all!

I learnt not to guide drywall screws into plasterboard with my fingers. The darn Wickes screws left well over a dozen little steel splinters in my left index finger and thumb

Neil

Very neat. Makes the rough-hewn sled my Suffolk is on look a bit sickly...

Neil

Hello H,

I have nearly finished drawn up plans. I'm hoping to write it up for ME in the New Year.

Neil

Hi Simon,

Others may disagree, but as this is a fairly modest sized lathe witha relatively light spindle, you could consider getting a backplate made that has the mounting holes and register for fitting mini-lathe sized chucks.

This would keep the costs down and you would only need one backplate for 3 & 4 jaw chucks and a ER collet chuck (if you ever want one)

Neil

FWIW I cut the eccentric strap for my 10V with a junior hacksaw as the only slitting saw I had at the time was 1/16" thick. There is plenty of metal for cleaning up the cut surfaces, even if a thin slitting saw wanders a bit.

Neil

Hi Mike,

I went self employed... but most of the time its been DIY keeping me out of the workshop and off the computer!

Neil

Thanks Martin,

It imports, but I'm not sure if what I get is what you intend!

Neil

Hi Paul,

Back in the day Hoover made some very lovely motors for machine tools, so it [probably isn't from a washing machine if it looks like the one below. If it has oil cups at each end pop a drop or two of oil in every day you use it.

Neil

Can anyone give me a link to a 'test' DXF file to test the import on this programme?

Sounds like my Dad's mouth... before he got his false teeth.

Someone recently pointed out that much carbide tooling needs to be worked fast so that the heat generated softens the cut, but the reciprocating action of a shaper limits the speed that can be achieved. That said I know some tipped tooling is meant for finer cuts and slower speeds, but this is the area where the superiority of tipped tools over HSS becomes a moot point.

Neil

Hi Graham,

Your main problems (aside from and excess of rigidity at the expense of flexibility) could be:

• No facility to tilt the angle of the tool in the vertical plane.
• Some sort of indexed facility to rotate the tool.
• Allowing the part of the tool to be ground to be kept at the right level on the wheel when tilted (tilting raises or lowers the tool tip a surprising amount, probably more than any adjustable tool holder would compensate for).

That said you could address any or all of these with ingenuity.
