Harry plenty of us out here with similar views although DROs have made it onto my milling machine. No need to crawl away and hide even if you do someone will track you down in my case SMEE who asked me to be a speaker at one of thier meetings.

Try Rotagrip I have bought lathe chucks from them at the better end of the market and found them to be very good. They are also knowledgable and helpful. No connection just a satisfied customer

I have both, the collet chuck of choice for me is the 5C l like being able to tighten and loosen with a chuck key I also like the ability of the 5c collet to hold short lengths of material. It can be done with ER collets but it's a faf.

I live about 10 miles north of Leicester not far away we have a specialist tig welder, he will do small welding jobs for beer money.

These are two tether cars that I built their is about 50 years of development between the two the modern car will run at about double the speed of the old one.

Just to put a bit of balance to what I am saying, currently building a Stuart Turner Sun engine it's making a very pleasant change from making new pistons for my tether car engines.

Jason they are nice model engines but hardly new. Tuned pipes were fitted to high performance engines in the1970s ringed pistons also disappeared before that. Model engineers used to be at the leading edge of model engine design and development for example Edgar Westbury but no one has really taken up the mantle for high performance engines. The only modern racing engine is the 0.9 cu in /15cc built by the American model boat racer.

Jason I have read what Dave wrote a little differently he said new designs I took that to mean modern. As nice as the old engines are model engineering seems to be stuck in a rut it's the same old year in year out. We could perhaps do with a breath of fresh air in model design a new challenge.

Sounds like there was a lot of tyre kicking going on.

My lad had an interesting experience went with £2000 in his pocket to buy a lathe just wanted to see it before he purchased it liked what he saw. The sales staff were not interested in him would rather speak to the old boys. He came home with nearly all the money, bought two files and a junior hacksaw and some blades.

Not an expert bought my mill with an R8 taper on the advice of an expert it was good advice it works well and you can get the tooling out easily unlike morse tapers a lot of mills don't have the slot in for using a drift .

I went yesterday it was fairly busy bought a few files and a rule I could see. I didn't see many competition entries a few on tables and some on club stands. It was pretty much locomotives and their seemed to be less club stands. Not a bad day out pre booked tickets worked well.

If you decide to go for an 8" table have a look for a second hand British one I got one from a well known auction site for £80 and it was like new no marks on the table just a dodgy paint job

Did you find the 8.5mm tap could do with one myself

Can anyone recommend a simple to use 2D CAD program I need to do some drawings that I want to put into a word document. Did Autocad 12 a long time ago.

John What would a bar of 2.5" magnesium cost collected. Would be an ideal material to make tether car chassis from.

i have a small bench top honing machine, I want to hone the big end of a conecting rod with a bronze bush. The bore is 4.5mm anyone know where I can get the hone mandrel and stones from without breaking the bank

Just logged in to say mine does it as well on the iPad not running anything else protection wise. Mostly I just read now only post if it's really relevant.

Jason, It is unlikely to be a tether car engine usually max engine capacity is 10cc and a two stroke. The current rules allow the use of four stroke engines at twice the capacity of the two stroke engines. It would be a challenge to build a car that complied with the weight limits. It is more likely to for a tethered boat they allow engines up to 30cc.

Bazyle, I am not complaining but making the point that ME clubs are too focused on running loco,s and this where the effort goes possibly at the expense of other forms of model engineering and the loss of new blood into the hobby. I understand the need for this focus to financially support the club but it's not what I want to do so i am looking for another club that maybe more accommodating.
