How to's / Re: Quick and dirty die-nut.

 Hi Guys
           Found some dark powder in a glass jar on shelf at the back of my garage the other day. Normally inaccessible due my ever growing stock of hard wood. I did buy some Casenite 20 yrs ago from Tilgears, and have searched many times for it in the past. The label I put on the jar has now disappeared, and I have bought other similar looking substances since. I must test it to see if I have hit the jackpot.
                                             Cheers David

Looking good I'm going the other route last year I had the exterior and roof done this year were doing the ceilings, insulating and putting osb plywood on the walls! There is a hell of a lot of shifting the same thing from one spot to another while clearing unwanted junk!

Nice .
I painted my floor in workshop and gamlrage but the drive gravel and cars have removed a fair bit of the surface paint , over the last 18 years. Just can't face moving all the gear out to re do .

Next time I'll try epoxy paint I think. Anyone got thoughts on the epoxy versions?

Course given our weather it takes days to dry.....

I'm getting really behind on posting my videos, lots to edit, just very overworked! At the moment I'm working on a feature film, making all the "iron work" and some more for a film set in the 1830ies.

here is a brief extract of the many things I have to do!

I don't think Elf and safety would approve!

Having enjoyed your many musings and designs over the years. I wish you a long and happy retirement. I hope you will still continue to comment occasionally and add value to this, and other sites ?

With the development of voice recognition software perhaps you maybe soon back amongst the throng?

Thank you from us all.

Hi,

I've been working on some more heat transfer stuff, this time for the chamber. I'll post it once I've finished,

Today we started laying the Aco storm drain on a bed of concrete - ran out of balllast so play resumes tomorrow, Also exposed the land drain connection that we  will be Teeing into and inserted a swept Tee joint ready for the storm drain.

I also today connected up the compressed air having made up a support for it's termination. The air plumbing is grafted onto that already in the Woodwork Shop where I'd left a blanked off Tee 'just in case' a couple of years back. It runs round the Woodwork Shed at ceiling height then plunges down to the 110 mm drain conduit leading to the Tractor Shed. I put an isolator valve in the line for future diagnostic purposes. In the tractor shed the airline emerges from the 110 mm drain duct at floor level and rises to a 'wall plate elbow; then via a ball valve to a PCL Q/D fitting. I will in due time fit a pressure gauge at this point just as a reassurance measure as the compressor is a very long way away !

Tools / Re: Bench Grinders & Lathe Tools.

Well, I've been pottering on with my project which is to fit my desk with a pillar bearing two jointed arms, one to support the phone and the other to support a computer monitor.  The pillar is 1" in diameter and has a series of circumferential grooves.  A plastic clip with an internal rib that fits into the groove supports the hub at the end of the arm.  Because I bought most of the kit on eBay I don't have the clips and the arm is not a current model so there don't seem to be spares available.

I'm making my clips from black Delrin and I've got most operations complete on the outer end of a piece of Delrin rod.  The next operation is to use a form tool to machine the internal rib.  (See sketch.)

I decided I didn't like any of my existing boring bars so I chucked a length of " x " mild steel bar in my self-centering four-jaw chuck, faced the ends and centre drilled.  I obviously didn't 'hold my mouth right' because the tip of the centre drill broke off!  I just cut that end off the bar, refaced and continued.  I drilled each end tapping size for 2 BA and tapped them.  Then I marked out and drilled and reamed a " cross hole at each end of the bar.  All standard stuff, so I didn't bother with photos.

The plan was for the bar to take " square bits at one end and " diameter bits at the other so I set to to file one of the round holes to " square.  That didn't turn out as well as I'd hoped - a piece of " square HSS fits and the 2 BA grub screw holds it OK but if I hold it up to the light I can see daylight where I'd rather not!

My piece of " square HSS that I used to gauge the hole is already shaped as a bit and I don't want to modify it.  So I need to grind a fresh piece.  Not long ago, I gathered together all my stock of HSS into one place but it's been borrowed by the shed gremlins, very annoying.   :bang:   :bang:   :bang:  So work is currently stalled until I can find it.

The  sketch shows the cross-section of the Delrin bar with the internal rib and the form tool in the boring bar.  It also shows a parting tool ready to part off the ring once the rib is formed.  Then I repeat to get a second ring.

That supplier never answered on my email. Ordered belts from Finnish company. All up cost about 95 for two belts delivered home (minimum order of 2 pcs. from Germany).

I don't have yet bomb proof way to measure axial/radial play and TIR on individual and mounted bearings....have to device something. Need first pretty close to 25,00 minus tolerance short shaft to stack the bearings and measure clearances.

Pekka you are right, huge run off from the roof, but all that water is directed to the rear of the building directly into a stream (branch of the River Line) so none comes anywhere near the farm yard thankfully.

The storm drain channel is purely to drain what falls on the yard itself and is ducted again into the stream.
