Nemet - Lynx

Thanks to all who replied on springs. I'm definitely going to have a go at winding some, but not this time, I want to get on. I rang Flexo, and they did me a deal, still very expensive, but by the time I'd drive to the nearest piano wire supplier and buy the wire not that bad.

For the record, Lee Springs will now sell minimum 5 off any one item at the catalogue price if you order on line, which is not bad at all. Unfortunately they don't have an equivalent spring.

Hello. Sorry to get onto this forum very late but I am building the Lynx and come to the part of ordering the pulleys and belt from HPC gears. An order for the 2 pulleys and 2 belts came to £49, which was bad enough, but then the cheapest shipping cost was £9.60. This for a few items in the smallest jiffy bag. I rang them and pointed out the post office will ship a small parcel for £2.90 but they would not budge. Any suggestions as to where I can get it all at a sensible price.

**LINK**

Hi Pete. Many thanks for the reply I have ordered parts from the company on the link and have reduced the cost from £59, and this may not have included VAT, to £21 including VAT. Now I may be able to afford the ignition system. I will press on and it should be finished by next Spring, unless a railway engine gets in the way.

Good evening all.

Always wanted to build an IC engine so about make a start on the construction of this one.

A couple of points - I'd rather like to use valve inserts in the head rather than seating the valves in the ally. Was hoping to look at the pics earlier in this thread but they're long gone. Any chance of them being resurrected?

Secondly, am I missing the obvious - how do you get oil into the crankcase?

I'm sure there'll be other questions en route but any help much appreciated!

Probably easiest to unscrew the breather and fill through that hole

Hi Jason. I have long finished the Lynx and it has run but is too big, too heavy and underpowered to do anything with . I put a oil filler plug an the rear cover. I did fit bronze valve guides but had a real problem getting the valves to seal and get good compression. One major problem with the engine, for me anyway, was setting the tappet clearance, you cannot get feeler gauges in there and there is no adjustment anyway. I looks good on the shelf. Best of luck David Murray

Thanks David, useful info but not a great endorsement!p

I think quite a lot have been built successfully so worth giving it a go.

Not too bothered about usefulness - getting it to run at all would be a major achievement for me!

Regards,

Peter

Hi Peter. Mine did run using glow plug. Plenty of noise and it filled the workshop with smoke. I also used a solid iron piston after honing the cylinder to a perfect fit and used a 12" prop. All the best with it. Best regards David Murray.

I've no idea what happend to the images

The clue is in the drawings and instructions for the Bobcat that Malcolm did after the Lynx, just scale for the Lynx valve heads. Make the blank valve seat/guides insert in the head and then drill the ports. It looks like I also included liners for the spring pockets, probably unnecessary.

That's great - a picture is worth a thousand words

Many thanks chaps!
