What Did You Do Today 2019

Yesterday i made the foundation ring of my minnie boiler all fit nice. i just need to silver solder the backhead and foundation ring on now.

I'm a firm believer these are the best guards you can have because being so easy to set up there is no excuse not to use one.

How does the plastic stand up to blue chips? Do they bounce off or do they melt it and stick?

Paul.

Hi they just bounce of with little damage but it will need replacement in a few years as it gets scratched.

Acrylic is less likely to scratch, but polycarbonate is tougher and less likely to shatter. I think my main one is polycarbonate. I've recently recovered some 5mm acrylic from a display cabinet to make a big one though.

Hi All,

Just made these two large bolts for an antique book press that was fiitted with riser blocks so the bolts were too long.

This was my first attempt at a serious thread 7/8" by 9tpi, 36mm AF and it did not go without incident!

I decided to cut both threads using either end of a single bar; the first one went absolutely fine and I was very pleased at how easy it was!

Turned the bar around and did the scratch pass into the dykem and checked the pitch just to be sure. Started taking 5 thou cuts in back gear.

Halfway through the next cut or so I got distracted and turning round I must have caught the cross slide and accidentally wound on 15 more thou! Result was a big bang and my Tufnol tumbler gear disintegrated! Wrecked the HSS cutting tool also.

Got a new one a couple of days later and installed it. Everything else had been left exactly as it was so I carefully did a blank no cut run to see that the alignment was all OK.

At this point my brain deserted me as I reset the next cut at 2 thou to check alignment again TOTALLY FORGETTING that the disaster happened halfway along the work and I should have started the check cut at the high point to the left of the previous cut!

YUP, another bang and wrecked tool and tumbler gear!

Walked away in disgust for a day or two when someone on here very generously lent me a gear so I could finish the job while waitng for a new one. ( Thanks Brian! its on its way back to you!)

Some serious lessons learned and finally got it done.

I am now the owner of what must be the two most expensive bolts ever!

Cheers, Martin

I got my rockerblock i/c engine running.It fired continually with the drill but wouldn't run ,I thought I would run it on the drill to bed everything in,whilst doing this I noticed bubbles coming from a head screw.I removed all of the screws and spread hermatite on the screws and reffited them,after adjusting the jet to nearly closed it ran and continues at every start up.To say I am chuffed is an understatement.

A job I should have done years ago, but finally making this metal rack was triggered as a result of having to go through a whole heap of metal to find the 20mm Sq mild steel I knew I had somewhere. In looking for that I came across a huge amount of Brass, Bronze and Ali that I had forgotten I had

They look beautiful. What was the material like before machining? presumably moulded and oversize but by how much.

You jig to hold the part machined part must be quite clever too, how will they be attached to the boat?

I think I have found a new hobby, searching ebay for a "hand metal shaper" It is very distracting.

Will a German one do, Barrie ?

Good job! They make very nice presents indeed. I think matching pairs are particularly hard to make - side by side comparisons highlight even tiny flaws.

Thanks also for improving my vocabulary with 'spalted' - wood colouration caused by fungi. I can't wait to use it as if I really was educated rather than being a complete pseud!

I've been working on the boiler for my Burrell-Boydell road locomotive but have almost reached the point where I need to use my clubs oxy-acet so I decided to make the hind wheel guards. These are modeled on those shown in an 1863 photo of the next and last engine to be built.

My drawing of the engine with a guard fitted.

The first guard partly assembled from 0.016" thick brass sheet and lots of 1/32" rivets.

Yes, I appreciated the connection, Barrie

... Equally tongue in cheek, I was assuming that if a Chinese model exists, it would probably 'bear some resemblance to' the Biax.
