Interesting use of the letters . I remember my dad had rubber moulds that were used for casting cheap badges and brooches using a low melting temperature metal . The silicon might just do it👍
Interesting experiment Rob. Someone suggested stacking the letters. I think that would work. I've used those letters before, but just sticking them on wood and painting them. Cheers Nobby
Hi Nobby. Quite useful little letters. I saw a video where a guy restored an old machine and the cast in name was missing, so he just glued on this type of letter, thinly epoxy coated it, then painted the whole machine and you couldn't tell it wasn't original. Cheers Rob
Hi Tony. Yes on both counts. I saw a video where a guy restored an old machine and the cast in name was missing, so he just glued on this type of letter, thinly epoxy coated it, then painted the whole machine and you couldn't tell it wasn't original. Would have been durable enough. Cheers Rob
Hi Kev. Yes, a lot of this is not covered on YT. It's suck it and see time. I was worried that the plaster of Paris would break trying to separate the sections when soft, so I let it harden, which presented another issue. LOL Been a while since I used P of P. At least the furnace kept me warm ;) Cheers Rob
All things are possible. I saw a guy in Russia cast some gears using silicon molds and it worked pretty well. Not as good as a machined gear, but usable. So that will be the next experiment.
Hi Rob. Proper green sand or Petrobond would have probably been ok. I've managed to get quite fine lettering to come out well with that stuff. Cheers, Alan.
Ha Ha. I will try the silicon method first. If it works I may even try casting a gear that way. I've seen it done on YT by a guy in Russia and the gear he made was usable, but not as good as a machined gear. I have a few other projects on the back burner as well. I've been approached by a few companies lately to review various stuff, but being winter and cold and miserable weather I'm not really in the mood to chase delivery schedules. Maybe I should review one of those small cheap diesel heaters to warm up the workshop ;) Cheers Rob
@@Xynudu I'd be very interested to see you try silicon, it never occurred to me to use that. I think Kev did a couple of videos on a diesel heater about a year ago, could be interesting to see what's om offer in your part of the world. Cheers, Alan.
Summer is finally here on the UKs Suffolk coast but anything over 19c is a heatwave here.
Another useful video Rob
👍👍👍
I hate the cold. Anything below 16 C is bad news.

Hi Colum. I will give it a try. Interesting exercise. Cheers Rob

Turned out OK for a first try Rob. Colour the surround in for more definition. Cheers Tony

Interesting Rob, you don't find things out till you try👍👍👍👍

@ 05:53 I have heard of the lost wax method of molding but not the lost wood method. interesting video. Thank You...
Ha Ha. If I had glued the letters to polystyrene it would have burnt out in seconds. Maybe next time ?
Rob, you could try double stacking the wooden letters perhaps? Use ordinary 'greensand' water based with a bit of bentonite in it?

But that costs money Alan ;)

This would be a good application for a 3d printer.
Yes it would.
