Re: Another Wild Rose Project

Sorry, I misunderstood - I thought it was centre drills that were hard to obtain. Yes, NC spot drills are probably not easily obtained from model engineering suppliers. We buy them from big trade suppliers. Good thing about them is that they last a very long time, so unless you crash them, the initi...

Re: Another Wild Rose Project

On CNC machines we mostly use NC spot drills which may explain why the traditional centre drills are not as commonly found anymore. That said, they are easily obtainable over here and don't cost much either - about £3.50 excl. VAT. I have a registered business so can buy from all the tool merchants....

Re: Disasters, Out-takes, Accidents, Fails etc.

Failure? Hmmm, that would be myself. I have a knack of failing at most things I do.

Re: Another Wild Rose Project

A slitting saw is just a saw blade. You need a mandrel to mount it on so it can be chucked in the mill or lathe.

Re: Another Wild Rose Project

Mild steel is dirt cheap when you buy it in bulk. We pay less than a Pound per kg. However in small quantities the cost quickly adds up. I'm fortunate that I can scrounge all the off-cuts I want.

Re: The SOL project

Best to use a schottky diode as they have less voltage drop. Any normal diode will work though provided the solar cell voltage is high enough.

As Philipy said, don't worry about using a 5V solar panel with a 1.2V cell. Unless very big, the solar cell will not provide enough current to do any harm.

Re: The SOL project

If I was going the solar power route I would probably build a goods wagon or two with the roof full of solar cells and a couple or more large NiMH cells inside. That way you could connect it to any electric loco via a couple of wires. It will be a challenge to have continuous solar powered running u...

Re: The SOL project

It doesn't look like there is any charging circuit in that. The solar panel just charges the NiMH cell. The LED driver shuts off the LED when the voltage drops below a certain point. Don't replace the LED with the motor - the chip has some current limiting function. You should run the motor straight...

1702 NPN transistor. Google it for spec sheets.

EDIT: No,it's a LED driver: https://www.aliexpress.com/i/32949338594.html

Re: "Garden Rail" 1994 Ross Harrison's 16mm Hunslet (Lilla)

.... A problem of doing this commercially is when your sub-contractor goes into liquidation. So for a third time the receiver did not return my laser cutting files to me. THis time although I had the files I could no longer open them! I don't follow. Did the company doing the laser cutting also cre...

I think you'll find the 6th post down in the 'New Models & Reviews' covered this in December... And let facts get in the way of a good moan? ;) Feel free to not use the forum it if you find it behind the times particularly if you are going to be rude. My thoughts exactly.

Re: Laser cut set track

What I meant was, I doubt there is a market for track from either material. Unless you are in Denmark and willing to weld the track yourself it would become too expensive compared to commercially available track. It works our cheap for me though as a DIY project. :D

Re: Annual loco sales?

Thanks guys. Whilst I now have the tool, I'm not sure I have the ability. I'd need the original loco to be able to design a body kit around it and I would also need an indication of what people are looking for, preferably pictures of the kind of detail they would like to see. There is a distinct sho...

I think with stainless steel you would have a market for this, great work.
I doubt that. Shipping will be a killer and by the time it's been welded the price would be close to Peco track.

Are you able to use stainless steel?
Yes, I can cut that as well. I have a TIG welder for joining the track.
