Is this DHL tracking information normal? I would have assumed "The shipment has been delivered from the parcel center to the recipient by simplified company delivery" would mean it's apparently been delivered? Though looking at the tracking it's not even left Germany yet. (Coming to the UK).

I wish there was a scale scene for touring/rally cars. Scalers are cool but I want a hard body escort with all the scale trimmings!

February last year I was completely done with RC. Fast forward a year and I have two current build projects, my race buggy is back up and running and I am already looking into my next project. Something with this hobby just wont let me quit

So I have a completely seized OS max 25. Possibly been sitting up to 37 years. It looks pretty bad inside, is there any chance to save it? I'm assuming not.

Strip carb off - take out glow plug - strip pull start off
Fill a small Tupperware / container with fresh nitro fuel ( must be big enough to fully immerse engine and have a lid )
Dump engine in overnight, the fresh fuel will help break down the old fuel and crud that's now turned to treacle like glue in the case, further adding to the stuck piston
Take out engine - allow to drop dry for 20 min ( or until nitromethane evaporates, usually takes a few minutes )
Replace pull start, try to pull, is it still jammed?
If so,
Place engine in vice to hold it
Put a FEW drops of 3in1 oil down the sleeve and carb Venturi
Heat crankcase , by heating I mean;
By heating I mean get a kitchen /chef blowtorch and concentrate heat on the OUTSIDE of the crankcase, specifically targeting the area where the top of your piston is wedged ( move it round in a ring formation, circling the heat 360° around the case )
(Heating the case this way concentrates heat on the case where the top of the piston is wedged, therefore expanding the case/sleeve where the pistons wedged only )
When approx 30-40 seconds into heating the case, start gently pulling the pullstart to move the piston ( it will help if your attempting to free the piston, by pulling the piston DOWN towards Bottom.Dead.Centre, as the top of the sleeve is the tightest /narrowest point, the bottom is the widest)
If your pulling after 30-40 seconds of heat and it's still jammed then stop pulling and carry on heating for another 40 seconds and try again, repeat as neccaesary.
Once freed, simply rebuild and refit! No need to flush as you've soaked it in fresh fuel
This method was taught to me by an old timer engineer friend, and has helped me free countless engines that others suggested go in the bin.

Thinking about replacing my rotary tool with a Dremel, which one do I go for? The router attachment looks interesting, so needs to suitable for my routing needs if possible.

Dremel’s big brother the Bosch GRO rotary tool. The industrial quality version of the Dremel. Downside is it is a lot more expensive but uses battery packs that last hours per charge.
Used to to have an old 300 series Dremel. Primitive but lasted through many years of abuse. The latest ones are a bit fragile in comparison.

Just got a notification saying my Ebay order has been dispatched. Turns out drunk me decided to buy an unknown "Vintage RC car" on ebay a few days ago. Guess we'll see what turns up .

I want to make a layshaft for one of my models. It just needs to be a 4mm thick metal bar, with 2 holes for pins to go through. What metal would you recommend?

What's the deal with UKMail? Just tracked my parcel and it says delivery was attempted at 18:56 but there was no one to collect. But there was 4 people in the house at that time, and no card has been put through the letterbox like their site says there should have been.

I had that too, was updated later to "delayed" however, he turned up 3 hrs later (saw the van outside) then left?!.
Checked the tracking again and it said "no one to collect, left with neighbour" Didn't even bother coming in the gate just dumped it with them as they just happened to be outside by their car. Lazy wotsit!! There is a map so you can see where he was at the time they said "attempted". Turned out he was 3 miles away on the first "attempted" I did have a rant at them but no response. Don't think they answer emails
