Tony’s Manor has made a little progress. Not happy with the cylinder covers, and the slide bar brackets didn’t print properly, but at least they fit to the chassis.

but the bogie springing works so that’s a win.

Reprint time…

and, work out how to make slidebars.

Bambu FDM printers have a “wood dust containing“ feedstock. It’s supposed to look (and smell) like wood as you print it.

a small platen has given me enough packing crates for the foreseeable future. I’ve weathered a few of them, and there are a few more in wagons. Modelu figure for scale.

in close up, they look a bit “hairy”, apparently a waft with a hot air blower or a rub on a bit of sandpaper sorts that out. Not sure why the plank lines seem to go through the diagonal bracing on a couple of them, the CAD is correct, so it must be an artefact from the printer. It is advised to use an 0.4 nozzle, the 0.2 would give better resolution, but is reputed to clog with this material.

I got 25 crates for a bit less than 3 quid, and half an hour over lunch on the CAD. Good value I reckon! I might do some more, rather smaller ones.

I shall do some barrels in the same material, one lunchtime next week :)

One of the things about this hobby is that it isn’t all about what colour, which loco, what date, etc.

Sometimes the diversions are fun, we’ve enjoyed many a frivolous rabbit hole over the years and long may it continue.

Sometimes, they’re bloody frustrating, as in a box of 8 3DP wagon “kits” that did not survive the tender ministrations of DHL on their way to Nick @magmouse . I’ll spare you the photos, but if you told me they’d played rugby with the parcel, I’d believe you. They certainly converted the contents.

And some things are curious. I have suffered a few print failures, then runs of good prints, then runs of failures. This morning was another fail…. And then the printer would not turn on again to allow me do a tank clean. The button was prodded and pushed and poked and in the end turned on, I sorted the tank out, recovered most of the resin, and grumbled a bit. Then the dumb thing would not turn off. Google. Ah, Saturn 2 power button, known, if not common, failure mode. Dismantling was not easy, but we got there in the end. After several attempts to stop the push-push button from sticking, I unsoldered it from the little PCB to which it was mounted, drilled a hole through the Power button, fitted a toggle switch and put it all back together. “ Reassembly is the reverse of disassembly” :rant: Which is why you need an electric drill, and superglue…

it seems to work, I shall test it properly once the dishwasher has completed its cycle.

Good grief, Simon. Talk about a series of unfortunate events! Hope the printer starts to behave itself - do you think the power button is anything to do with the print failure, or is that just a coincidence?

In solidarity -

Nick.

Well, pleased to report the first high-body has just come off the printer, looks fine, it’s been washed and will be left to dry overnight before curing.

there’s a low body on the printer now, and when I’ve finished watching the end of Texas at Belladrum (with a snifter of something warming and maritime, from Wick) I’m off to bed, fingers crossed we have two good sets of bits in the morning, and two more before work on Monday.

jury’s out but my suspicion is a dodgy switch is the likely cause of the earlier grief. Let’s hope I’m right!

(and ”unfortunate events”? Lemoney Snicket has nothing on me! July was a complete b….)

Ah - Old Pultney, a fine choice.

Since replacing the switch, I’ve had five prints with zero issues.

Number six is cooking at the moment, I’m just off to work, and the washing machine is struggling to spin dry my Kevlar biking jeans so there’s lots of noise & vibration in the utility room. Madame is WFH today, so another couple of washes will go on.

if print 6 is ok, I think we’ll conclude that the push-push switch in the Saturn was to blame for all the world’s ills. I can wait til tea-time to find out!
