I read about this 3 cylinder glow i/c engine on Model engine news site. It seemed to suggest we are able to buy plans for it but I have been unable to locate any. Does anyone know anything about it? Peter.

I've been having a bit of a sort out and came across these brass castings. They are 1and 3/8 inches across and the boss in the centre has a 3/16 hole right through with a cross hole for what I would imagine would be a fixing pin. The small rounded piece has cross hatching on so looks like some...

This is the worst I have felt since starting this hobby. I feel so dejected and I am just irritable and don't want to do anything. I have messed up on my loco wheels. Only noticed when I started to machine the axles that the wheels are 1/16 inch too thin which is the thickness of the flange...

I have been thinking of this for a long time. My situation is that I am becoming something of a recluse and have been finding making any decision very difficult especially when it involves socialising and the like. I have to do something about it and decided (eventually) that this would be a...

Thought I would share this interesting little job I have done for my cousins. They are keen on aviation history and have founded a museum based in Surrey UK. One project is a cockpit display from a P63 Kingcobra. They needed two seat brackets so they could bolt the seat on and came up with the...

I need to make a new draw bar for my mill and it is 1/2x13 unc. I would like to screwcut one on the lathe and found a table in L H Spareys book that shows for an 8tpi leadscrew I should use a 40 tooth driving a 65 tooth gear. In the Myford book and inside the gear cover there is no mention of...

While reading stuff on the web to try and extend my limited knowledge of how engines work I came across lots of references to camless engines and electromagnetically actuated valves. I wondered if anyone here has experimented at all. Most seem to use two magnetic plates and springs like this...

I have a scrap box of plastic and was wondering if there is a positive way of identifying ptfe. Peter ???

With allot of things I need help with I find it very hard to explain simply what it is I need to know and more often than not blunder on without knowing if I am doing it right or not because I was unable to get into words what I want to say or ask. I hope this comes across ok. I am having...

I've come to the conclusion that my shop just doesn't smell right. It's not bad, I like it but it is a mixture of wood, paint and everthing else. I have just received a parcel from GLR distributors. When I unpacked it and got to the metal bar some old memories were stirred by the smell. When I...

I can now join you happy band of people who have built and run an engine. I am interested in i/c mostly and joined this forum to learn more about them. What I did learn was how infectious other types can be. Also that I needed a simpler project to help me serve my apprentiship. So with...

Hi all, I am having a problem which appears to occur on this forum only. First the box that showed the first lines of a post when you hold your curser over the title are not there. Neither does it work on the smilies when I am posting. Second when writing posts long enough to need a slider bar...

Hi all, my brother has asked me to clean up the commutator on a car dynamo. I have done one before in the dim and distant past when I was young enough not to worry about things and just did them,usually got away with it too ;D Now though I have to think too much and worry alot. I need some...

I seem to have missed the plot regarding these so called rocking engines. I have tried hard not to let anything else distract me from all the unfinished projects I have but am failing miserably. I have searched for an explanation of how the rockers work and why they are called such but can't...

Seeing all the hit and miss engines on here I am becoming quite taken with them.While searching I came across this beast. It's been on nearly a year so apologies if you have already seen it but I just love the sound and all the smoke rings. http://www.youtube.com/watch?v=iLAic2uVlWo Mo, 8)

I want to help a friend out by machining an alloy prop driver for an engine conversion he is doing. He has produced a drawing but I can't work out the best way of going about it. The large dia with a small 2mm boss fits against the flywheel. If I start with that end it only has the 5mm to then...

I need some help please. I have a drawing in a word document sent to me by a friend that I would like to post here. I know the additional options doesn't work for photos but is it ok for files? Peter ???

The designer of the Vega I am trying to build has specified EN8m but I cant find a supply for the few inches I need. Just wondering if anything else is suitable. They are one piece and lapped with a cast iron ring in the piston. It also shows a couple of what he calls heavy metal inserts in the...

Anyone seen one of these before? It's a Beaver A and was made by a local firm here in Norwich. I bought it from a retiring engineer friend in the 80's and he moved it across the road on a hand cart only removing the turret to lighten the load. According to the manual it weighs nearly 9 cwt. If...

I started to build this engine when it was published in Model engineer magazine in the 80's. I am now going to try and carry on where I left off. I have to work on a tight budget but have ordered the three gears it needs. I managed to find in my box of aluminium the piece for the timing case so...
