20180905_143510.jpgCurrently making another Muncaster engine so I thought I would also make the simple reversing valve detailed in the 1912 book. Works well and will be incorporated into the new engine. Also gave me a chance to try out my "new toy".

Many of you will recognise the small circular table, sold by RDG which was great for the semi circular curves in the valve head.

Some feedback on the table. It's very small, 2 1/2" table diameter so only good for small scale modelling but is well made and I think good value.

Today's efforts had me ordering the second shed to be delivered with the workshop building second week in October. This will ensure there will be no infringement on workshop space by garden tools. mower, garden fertilisers, building and decorating tools and the like. Also enjoyed a good lunch at Farm Centre.

Not engineering progress but one step closer as the new base for the workshop goes in on Monday.

regards.

Good luck on no infringement of workshop space, theory is great but practice doesnt seem to happen. Despite having her own shed for gardening stuff, my workshop seems to fill up with various items totally unrelated to workshop. Post again in six months and let us know if it happens.

I finally got this house number plaque done. I'd been poking at it in F360 for about a week and couldn't get the rest machining to cover everything. I found Cut2D did it with a lot less hassle, given this is what it is designed for. I still did a lot of manual jogging around on the machine with the cutter at full depth to clean up. I missed a few bits where I was too shy to manually move the cutter so close to some features, might get some riffler files to finish them up.

The size is 200 x 125mm, using 8, 6, & 2mm cutters.

Bad bowing on the stock might account for some of the roughness but a sea of paint should hide a lot of sins.

Yesterday; rejuvenated old CI garden parasol stand that had its paint flaking off quite badly. A few minutes with a rotary wire brush & a battery drill soon had the old flaky paint off. A good coating of etch primer followed by a couple of coats of rattle can auto spray soon had it looking nice again. Machined up a piece of brass & threaded into the locking screw to extend the grip & as a protective measure for the parasol shaft...

Thanks Dave I certainly will. I know exactly what you mean. One trouble I do have is when the Domestic Authorities arrive in the workshop, she will pick something up I have recently purchased with the comment "I haven't seen this before" My usual answer has now worn too thin which was "oh I've had that for ages, I think you bought it for me".

Ah well.

Ian, I have similar problems when acquiring new tools and equipment, I have a system whereby I order on line and place all orders and confirmations in the archive file on my IPad, wife never looks in the archive even though we share the one email address, then I have to make sure any deliveries are not observed, not always successful in that but did manage to order a new bench mill and it was delivered whilst the domestic authority was out, did have to fess up though when she found it in the workshop. Had a tidy up in the workshop this afternoon, surprising how much just accumulates in there, darent throw anything away because l will definitely need it then.

Phew! Just converted several cubic inches of 6082 into swarf. You know its time to take a break when you change the chuck jaws and they are too hot to hold! And parting off 2 1/2" at 470rpm under power feed is 'exciting' even in aluminium alloy.

Just spent an hour watching my local computer specialist fail to recover any files from my second hard drive which held my CAD drawings and documents for all my projects over the last five years or more! My own fault for not backing up, I know, but blooming annoying, nevertheless. Managed to retrieve my last two ( unpublished ) articles from my email account, but that's all so far. Luckily I put a lot of stuff in albums on here, so when I have a day to spare, I'll resave all the photos from there. Needless to say, I'll be doing regular back-ups from now on. Learn from my mistake or regret it like I am.

There are specialists who will be able to recover your data (GCHQ spring to mind...) but it will be expensive.

Neil,

Yes. He gave me the number of a company in Norfolk who do this all the time in clinically clean labs. Cost? Between £450 and £500 minimum!! No thanks. I'll just nurse my damaged pride.

I had the same situation with one of my hard drives. Luckily all my pictures and docs were backed up but for some reason my videos were not added to the backup. Also lost were a number of work files, although I could cope with the loss of these. I was more peed off about the dive videos I had taken on Thistlegorm and other wrecks in the Red Sea. I sent it off to one of the specialist, knowing it could cost be around £500 but they were unable to retrieve any files after several weeks. Luckily it was a case of only pay if they get something like 75% of files of the disk. So did not cost me anything. All photos are now held on a mirrored pair of NAS drives. Each drive set of as a RAID 5 set. So data across three drives and an automatically switched in hot swap spare drive. All other stuff is up in the Cloud.

Ruined one and a half perfectly good endmills today in the process of turning a foot length of 2 1/2"x2" EN36 bar into 2 1/2"x2"x1/8" channel. The first was a 16mm carbide one. I'd set the cut up perfectly for the start of the initial slot. 1800rpm, 0.4" DOC, 4.5ipm feed (flat out on the feed). Should have been noisy, exciting and effective. Started off noisy and exciting, then became noisier then stopped. Some twat had forgotten the quill lockcrying. The cutter ramped down, then stalled the 2hp spindle motor followed by the 1/8hp feed motor. Set things up right again and had another go. Worked a bit better, apart from the fact that the cutting edges had suffered a bit on the first cut and weren't working as well as they should have:-

 

Re-trenched, with far more conservative settings and a 20mm HSS rougher. This did very well cutting the rest of the slot, then I went on to widen the slot. Something's not right, Climb cutting wasn't working at all (note:- X feed play is 4 thou, so not normally an issue). Swapped over to conventional cutting and chomped away at the sides of the slot. I'd done 5 1/2 passes, taking .1"x.7" each time and the machine starts behaving like a Kango hammer! Close examination of the cutter shows edge wear and chip that could be the cause of the problem. Tomorrow, I need to think things though and see what I'm doing wrong. I think I'll have to slow down a bit:-

 

 

I'm not as devastated as I could be about the cutters. They both came from the turbine blade shop at work when the b****rds shut it down. I only wish I'd liberated more than I did, but I hadn't even finished building the shed at that point.

It must be the season of drive failures, my pc has just decided that my data drive is missing luckily I back up hourly and 2 hourly to two different drives so minimum loss if the drive has indeed failed but it could just be windows telling porkies, there's another day tomorrow all untouched to look at it. Don't ask why I keep backups!!!!

I have three separate backups and never have more than two connected to the PC in case of ransomware attacks.

Years ago I put in place a policy that everyone should keep their files on a fileserver with RAID and regular automated backups with regular changes of backup sets.

Of course one staff member decided they wanted to keep all their precious data (years of it) safe on their own machine.

Guess whose hard disk drive died?

We also suffered a server crash once, virtually all the staff lost a few hour's work.

We had a very professional 'managed service' ... and only suffered one significant failure:

The RAID controller was 'bricked' whilst they were performing a firmware update crying 2

A few years back. my QNAP NAS (mirrored drive) failed and bricked both HDDs so I lost everything on them. Luckily I had periodically backed it up but I was still well pissed off. The root cause was the external PSU going West, corrupting the HDDs and/or controller as it gradually failed.

No excuse for not backing up. These days it is often just a case of plugging an external (pocket) drive in and it will do the rest automatically.

I did two things today. I cut some new nameplates for my freelance 5" gauge 0-4-0 because the ones I did before looked far too big when I went to put them on. Should have printed them out for a trial but I didn't have to loco home until last weekend.

The new nameplates gave me a chance to try holding the brass down on the MDF with masking tape and superglue. It worked well and held the brass flat. The superglue let go in a few places allowing a small amount of lift. On one plate this wasn't significant because it was off the end of the job and on the other I noticed it before I started so flooded some more glue in there and weighed it down for about 20 mins. I noticed a small unmachined fragment in the lower void of the 'E' after a coat of black paint so that needs cutting down manually later once the paint dries.

There was one exciting moment when I went to profile around the outside of the plate and forgot to change Cut2D's default feed units of mm/sec to mm/min! I'm assuming the table moved at it's max rate but the 2mm cutter didn't break... I was equally relieved and impressed. The finish was rubbish though.

The other thing I did was move the lathe off the wooden blocks and further away from the mill to re-open the passage between the two so I can get around them easily. The move went without incident this time. The lathe is still a bit unsteady at the tailstock end so that part of the stand is obviously not much good. When it was on the blocks I could just move one of the two tailstock end blocks by hand with no resistance.

I think some adjustable feet might be a project in the near future unless the batch of brake parts I make on it soon come out ok, in which case I'll leave it alone. I really hate working on the machines or tooling rather than the project or loco I'm trying to build.

img_20180910_170442.jpg

That was actually all yesterday. Today I am going to fix that little unmachined bit on the nameplates, fix a piece of plywood to the bottom of a tool cabinet that is of such appalling quality the castors screws simply pulled out while moving it around (don't but tool cabinets via eBay!), and perhaps making a start on the CAM for the weight reduction pocketing of the sandboxes I made last week. It would be quicker to do it manually but I need to learn to use my new machine for something other than faux-cast plaques.

I feel for you Mark. It's always a shame breaking a larger cutter. As long as the job's not ruined things could be worse.

I had a computer monitor failure yesterday. New SOTA thing arriving today, plus replacement electrolytic capacitors for the old one. In my experience a dead monitor is nearly always a dried out electrolytic and at £3.22 for a complete new set I have to try.
