I am a bit involved in that big ride- lel, It would be rather fun to have some auto-pedalling articulated mannequins, would you/could you  be inspired?

I thought the point of Audax was to become an 'auto-pedalling, articulated mannequin'  :demon:

Why does life get busy as soon as I start a new project?  >:(

I'll have to show a couple of work projects until I can make progress on the fun stuff again.

New D&T teacher has been persuaded by someone from the Music dept to make musical instruments with one of his classes. He showed me a Instructables page on making a mini ukelele from scrap wood and asked me to try it out.  ::-)

We'll use planed timber rather than old pallets.

Carving out the sound-box


Sound-hole drilled, shape cut and headstock sawn at an angle...


...and the bit cut off is glued back on like this:


A set of tuning keys costs about £3


Online fret calculator shows where to stick cocktail stick frets.


Now he's decided it will need to be done as a 'kit build' as they will be one of the younger classes. I will have to program the CNC machine to cut the wood to shape, and I suspect we will all be sanding and tweeking the uke's to get them playable  - he wants 60 students to make them.  :facepalm:

EDIT - now realised that I've mis-asembled the tuning keys.  :facepalm: :facepalm: :facepalm:

Another job is making a replacement crown guard for the circular-saw bench.

The original, plastic one is breaking apart.  :(


A side is marked on sheet steel....


...and cut out on the guillotine.


Once cut, holes are drilled in the two sides to hold them together...


...so that they can be ground to matching shape.


Strips of steel are cut & bent to shape for the top, then tacked in place with the MIG welder.


The rest of the welding is done with the oxy torch. I'm normally neater at gas welding, but there were slight gaps to fill.  :facepalm:


A bit of tube is cut with the angle grinder to fit in for the extractor port, and welded in with the MIG. The angle grinder is then employed to tidy it up.


Hopefully I'll get time to finish it tomorrow.  :smug:

Thanks, Jurek.  :D

Saw-bench crown guard continued.
Plastic clamping bits cut from an old chopping board and sacrificial side cheeks from ply (If the crown guard gets pushed to the side while cutting, the plywood bits touch the blade first, rather than suddenly hitting metal with the blade.)


Ready for painting...


...and primed with red oxide.


If you are wondering why I am making one rather than just buying one - the last spare part we rang the suppliers for was one of these:



...they quoted £70, plus P&P, plus VAT!  :o :o :o

I made one up from a standard £3 part.  :smug:

Have you thought of just making the whole machine from scratch?

I once start making a metalwork lathe from scratch - only 10" between centres, 3" swing. I got the bed, cross-slide and feed screws done and the parts cut for the headstock, but then managed to pick a secondhand lathe up cheap.  :thumbsup:

Blimey John, you missed the opportunity to convince the school that you needed a tig welder for that job.

A little more progress on the cycling project, today.

The head tube is cut in half and the ends faced and champhered on the lathe...


...to make two 75mm head tubes.


The blades (tines/legs?) are removed from the forks.

That uke looks great. I once tried making a violin but it didn't really work. The sound box was the tricky bit and the whole thing sounded dead. Stradivarius I ain't. Please put up some video of how it plays, when finished, I'd be really interested.

Sorry progress has been a bit slow of late - I only been facing a few bits up o the lathe for the project, although I did drill an important hole yesterday that took all lunchbreak (a 16mm dia., angled hole, off centre, through a fork-crown can't be rushed).

I bought some steel this afternoon, so hopefully will make progress soon.  :thumbsup:

I bet many of you will guess what I'm making from this shot:



A hole is cut in some ERW box section steel:



Althought I have 36 & 37mm hole saws, I needed 34 & a bit  >:(, so I drilled at 32...



...and filed...



...until it fits a head tube.
