Engel U177 IX D2

Back to the pond.

Prop shafts OK now. But WTC seal now not good. Air under pressure is takingthe easy way out.....

I had a neoprene gasket made but it seems to be too rigid. I have invested £2-99 on ebay for some neoprene tape- hopefully it will be softer & give a better seal.

I have also bought a couple of lead moulds from a fishing tackle shop to cast some ballast. Yet another skill that hopefully will be gained from this project.

Ok, if the neoprene stuff you bought is not working you can try my type of seal,see my latest picture.(have to find out the english name of it)
by the way,do i understand that the boat is now "sinking" when you fill the tanks??
Cheers,

How did you mount the pressure switch?
I have been following your great series and have just begun in earnest with my U177 but cannot figure out how to mount the switch.
I notice Engel have a mounting bracket as an extra which I think I will have to get or do you know of an alternative.
Thanks and keep up the photos.

Hi

Things have been quiet with the sub - a test dive in our pond showed her to be a bit bow heavy - foam has been added. But since then a combination of holidays , xmas & weather & football season starting has precluded another test dive. The completed model is too big to handle myself & I have 3 daughters who will not help...... hopefully I will get her out in february when Stoke are not playing at home when an interested friend will help.

A silicone rubber spray has proved useful for sealing the WTC lid.

As to the pressure switch I used the mount supplied & some elastic tube to hold it in place on the mount - seems solid enough.

You could try using a length of O ring material as a gasket to seal the lid, Ramesh uses this very successfully. Hopefully the picture will show the idea.

Peter: you can use the device Engel is selling for securing the pressure switch. I made a thin metal strap around the switch and fastened that on the bracket which holds the piston tank.
Rob: I take it that your boat is finished;can we expect some pictures you promised earlier?
Kind regards,
Martin

Hi Martin

You are right it is finished. I will do my best with some photos when I take it for an outing.

Life has been hectic so everything bar work & family has had to take a back seat
