I am currently working on the tooling to injection mould new quality trunnion seals that won't perish after a year like the one's currently available. The photo shows the holder with the core fitted and centred. This tooling fits my mate's injection moulding machine.
The rubber engine side cover seals on the market are a terrible fit. We have designed (CAD) and tested new ones and have already commissioned a batch of proper fitting water jet cut NBR seals for the side covers and for the rocker cover.
They will be available quite soon.

Excellent news, well done. Those look like the seals for the upright. Will you be able to offer the ring ones for the fulcrum pin as well? Look forward to seeing the other parts too.
Excellent stuff!
Will you be advertising them on here?
Best wishes,
Mike.
1954 Series 2: 4 door: "Sally" -- Back on the ground with (slave) wheels, now being sprayed by me, slowly......
1970 Triumph Herald 1200: "Hetty" -- Driven back from Llangollen in Wales (twice.....)
1952 Morris Minor MM highlight with sidevalve engine still fitted, wants work, so joins the queue for now......
Not as such but I will mention a procedure. It will be my mate who will do the selling as I don't have a business. I just did the design work and made the tooling.
Main mould finished this afternoon. Just needs to be milled/drilled for the injectors which is easy enough.
I will post up a shot of the first test piece which will be done in PVC and then we can try other rubber compounds-I hope all of this works!

I am as much interested in the lathe as the seal moulding tool especially as it has a parallel bar bed and cross slide. Could you please tell me the make of the lathe and is it manual feed or a CNC unit?
Regards
Phil
Phil,
The lathe was built the at our company works in or around the 1950's. A trainee built it as a project for his master craftsman exam at the time. He sold it to me when he retired around 1984. I rebuilt it in the years following and changed a lot of things. It is not CNC, just manual feed but I can attach digital slide gauges. The chuck is made by Forkardt and is a precision unit. It is driven by a three phase ABB variable speed drive. The downside is that it has no provision for thread cutting. I have another small Proxxon lathe for that purpose.
Regards
Declan

Roy,
Probably not-my mate says it should only take approx. 30 seconds to inject, mould opens automatically , part removed, and then the next one.
As soon as he finishes his current production run we can test it but that could be a few weeks as he has an order from Deutsche Bahn (German federal railways) to complete.

Many thanks for the details on the lathe. It looks very good. I just wish I was that good at making engineering items.
My own lathe is quite a bit older - is German and was made by Oscar Ehrlich.
It has the capability to produce both Whitworth and metric threads if required though.

The first batch of samples for the new nitrile seals for the rocker cover and the tappet chest side covers arrived yesterday. They are a lovely fit and we are quite pleased with them. We will test them over the weekend.[frame][/frame][frame][/frame]

See you as soon as I'm back from collecting those fitting kit for the T9 box.
