Re: Airfix 48xx with High Level Kits chassis

My favourite tool is a scrawker with a chisel end ground out of a Xacto craft knife blade. It still has a remaining bit knife edge too. I don't break many (any) hacksaw blades and my ground knife blade still fits the Xacto handle.

Re: Best Glue for the job!

So now we know of a cyano with decent shelf life. I wonder which it is ? :D Its Vitalbond CA Super thin. But I don't think it is notably different from other super thins I've had in the past. Super thin note. Cyano is not a good gap filler as its hard and gets brittle in big chunks. If you've got g...

Re: Best Glue for the job!

When cyanoacrylates first arrived they were definitely temperature sensitive and didn't have a very good shelf either. I got in the habit of keeping it in the fridge. I suspect the modern stuff is better but I still keep it in cool, my current bottle has been in there for some years as I don't use g...

Re: Ralph's workbench

I agree with DaveB that some sprung systems are better at damping out oscillations than other's. For CSBs the fiction between spring and fulcrums will be paying its part as will friction between axle block and the horn guides (if we can call them that). Practice says I have never seen a CSB chassis ...

Buck Jumping on Mass - The Build Phase

Part 16a – Getting the chassis going again “Here ends work on the chassis” I said, and so I thought, after all it had been a running chassis for quite a while. However I decided I had better just retest it to ensure all was still well with the world. And it wasn’t. First of all, one of the motor le...

Firstly, and I have seen this mentioned elsewhere, the Alan Gibson kit completely omits the small splasher over the leading wheel.

Re: Pull the Other One!

Getting solder to run up the inside of a tube is always difficult and a blind hole is worse. It really needs to be clean in there which is harder to achieve, you are expecting the heat to travel further, and boiling flux and expanding hot air will tend to blow the solder out when you're hoping surfa...

On a good day, with a following wind perhaps. Sod's Law says it won't. :(

Given that total failure gives an off centre error of .0025, is that sufficient for to us to care?

Re: Alan Gibson crankpin nuts

For round ones I'm in the pin chuck camp too, for both fitting and removing. The narrow section of the nut will fit nicely in the right chuck* and you can tighten it down so you have a good grip. They then stay gripped until you let them go, so sacrifices to the Great Carpet God are avoided. You wil...

Re: Socially Distanced Challenge – CR Class 488 Build

I too have noted that drilling cast brass bits can be a problem. Having had a good read round the internet, it seems that what is in "brass" is quite moveable feast. Silicon is added sometimes because it makes the the metal flow well and fill the mould, but results in a harder casting. Lea...
