What Did You Do Today 2019

Yes it was Niel. The weather was good too which always make the day better.

Just came in from gardening [hailstorm stopped play] and found this whilst browsing: **LINK**

Over the recent Bank holiday weekend I assembled enough of one engine to have it sitting on it's own wheels:

After I'd recovered my jaw from where it hit the floor my reaction was bleep bleep that's seriously BIG! Where on earth am I going to put the second engine? It's just as well I moved the parts out of the kitchen, the assembled engine won't go through the door. Fortunately I got the specification for the front door correct when it was replaced a few years back, there's an inch or two of clearance.

Im jealous Andrew. My wheels have been clamped to slab of 1” aluminium for months awaiting riveting. When i made my first set i was in my 30’s. Swinging a 3lb hammer was not a problem, you ached and got better. Now in my 60’s i have to pluck up courage to do over 100 1/4” rivets .

Your machine looks good i have to say

Had a good day at the Doncaster show. Lots of nice models but I still think Mike Sayers two Bentley engines are absolutely fabulous.

Lots of people selling 'used' kit so was able to increase my R8 tooling for new Gates mill, some tips for various cutters, a few bits of other tooling and a few castings and gears for Sanderson Beam engine kit which is ageing away till I have the skill to attack it.

Today finished cleaning and repairing a small collection of bits and pieces I either brought from the weekend steam rally or been given the weekend before. The first was a vacuum pump which was from someone who brought it new and it made noises it should not the company supplied a new one and told him to throw it in the bin.

An hour working on it now up and running like new well it was new but now repaired

Next was a clean up of a selection of tools from the rally costing either £1 or £2 most had a very light rust. many items are Moore and Wright

And lastly again from the rally a compressor cost of £16 and the switch did not turn off but everything else worked so another £12.79 and now all up and running.

So that was my little list for todays work in the shop

Congratulations Andrew, that's a huge milestone achieved!

Neil

Hope this is OK to post this.

Today spent turning Ali not sure of what grade. The end result was this pen I did this with hand tools as in the second photo mainly the top tool for the main shaping certainly a learning curve but found the best angle of attack in the end.

Once turned I used 600grit to give the brushed effect I was originally going for the full polished look but glad I did not. The gold parts are from a kit

Derek,

It looks good. Nothing wrong with making models at a scale of 12” to the foot.

How do you find the grip? I reckon they need some form of knurling or rings to make them easier to grip.

No problem with grip I make them from wood and resin as well the resin I also make with a smooth finish and again no problem with gripping them.

I did think of adding a knurled area but went against it

This one sits nicely in the hand and just a nice weight

You're a better man than me; I couldn't even close a 3/16" rivet with a hammer. Well, not strictly true. I can hammer the rivet end flat with a hammer, as I'm doing at the moment with the strakes. But no way could I form the domed head with a hammer. I got so far, but couldn't force the head that last little bit. So I resorted to the flypress. Much less drama and less chance of hammer blows in the wrong place, followed by naughty words.

Today (well over the last few days) I have been making some model boxes to transport Free Flight model aircraft.

My selected material was 'Corflute'. A lightweight corrugated plastic material that is typically used for signs. Normally very difficult to bond without plastic welding.

I conducted some tests on various adhesives and discovered that some of the readily available modern adhesives actually work very well, even for bonding Corflute to Aluminium alloy.

I wrote up my results here Glueing Corflute Plastic in case anybody is interested as I obtained some useful results.

Danny, Useful information. I know this plastic as Correx. Perhaps you could add that tradename to your article to help search engines find the advice too.

I made a wind vane model of my favourate aeroplane, a Cessna 185 B at least 10 years ago using plastic realestate signs made of Coreflute or similar type of plastic, no structural failures, even with wind to 100 kph, and snow loaded about a foot on top of it at another time. Had to replace the prop bearing 4 or 5 years ago. Can't remember what glue was used, probably epoxy from the $2 dollar shop.

Thats impressive Andrew and quite a sizeable beast, from starting how long has it taken you to get to this stage.

Got bored and in the interest of science tested the perspex shield off my Warco lathe's tool post by shooting it with my trusty Webley Premier .22 air pistol.

For comparison, first test was of a sheet of 1.5mm DIY store acrylic as sold for glazing sheds etc.

Anyone planning to use this stuff to protect themselves should think again!

The performance of the Warco guard was more impressive - it stopped the pellet fired point blank with no damage to the guard. Although being 3.5mm thick helped, I guess the shield is made of tougher plastic than DIY store sheet, perhaps polycarbonate. Look very carefully and you can find a .22 diameter smudge on the greasy surface:

Before and after shots of the pellet show it to be badly crushed after impact:

The lead pellet weighs about 1.2 grams and would have been travelling at about 220mph on impact, about 8J of energy.

The shield passed the test! Whilst I don't use the tool-post shield because it gets in the way, I keep the chuck guard in place and now think it could prevent a high energy accident.

No duffers were injured during this experiment...

Dave

Nice demo, Dave

One would have hoped/expected that the Warco item would be Polycarbonate ... But it's still comforting to see the the performance.

Maybe run of the mill but I,m cock a hoop my 3" TE passed it.s hydraulic test today

I finally finished levelling my Warco BH600 the hard way with shims under the pedestal, and made my first bits of curly steel.

Seeing the shield test above reminds me that I need to refit the chuck guard that was removed by the previous owner.

Congratulations on the the successful hydro test Harry! well done.
