type ix c [u505 late]

I just received this today nothing glued yet

Very Nice,Hope your not going to cover it in that leopard skin.

I think it looks quite...quite...different?

opening the flood ports      I drew a sharp flat blade on the raced part inside till I was flush with the hull and poked the remainder out with the blade

Rather you than me, Willie...that was one reason why I chose the Type XX111, all the flood slots are pre cut.

Looks as though you're doing a good job, though...good luck, and keep posting the pics as you go.

I was dreading this but a lot easer than i though now the stbd side

I tried to buy 65mm clear plastic tube the company cant send it to me because I live in the islands because I have iv31 post code but I live on the main land so I order 65mm aluminium at half the price £ 9 free postage the daft thing is the companies are close to each other

The Post Office seem to have some very strange rules and regulations...some post offices say you can't post this, that or other, you go across the road to a post office situated in a supermarket, and they take it quite happily. I can't see the logic behind their service, they seem to be shooting themselves in both feet!



Richard

the plastic company don't use the post office, the aluminium do that the diffarence

drilled each end with a 1mm drill and slotted with my 1mm slot cutter'

That's excellent, Willie...I'm impressed! So, when (if) I ever build another version of U-441, you'll be the man to open up the flood slots in it....

Richard

this is the first time I have done it though I slotted plastic be fore and the trick is keep your tool clean same as drilling the stuff it dose not take much to clog and destroy your work .a little bit clean. a little bit clean sound teaduces but stops that nasty build up that destroys and your flood slots if you get it to me?

An interesting observation, Willie.

The only advice I have seen on cutting plastic is to keep the cutting speed high so that heat gain is lost in the chippings.

Maybe this is the same thing - at low cutting speed the plastic just melts onto the tool?

I found out drilling the plastic styrene on models at high speed melts to fast and stick to the tool I hand drill this plastic when slotting I use a slow speed to make sure it dose not clog or it just build up on very small tools as it comes out twice the size. other plastic like perspex etc I machine faster as you say getting rid of the chipping fast with big tools will stop this but with 1mm?

the  three bottom slots not cut just now to close for gluing small ones on top also cutout

You're cracking on with that, Willie!


Richard

that's the front all done

I decided to go with 3mm brass tub and 2mm shafts the brass tube has a 0.45 wall so it gives me 0.1mm clearance for the shaft any comments welcome willie

how this ,I seen clear tube on the net £15-02 pence so I phone the company explained I dont live in the highlands and could he post it to me yes he said the tube will cost you£5-50 and £5-00 postage I said I will do on the internet no he said do it on the phone or it will cost you£10 standard courier charge, the tube is64mmx3mmx500mm

That's a bit sneaky...it's amazing what you can save for the price of a phone call.

the shafts are 2mm stainless steel push rods perfect fit for the props when screwed in nice fit to the threads

Nice work, Willie...have you thought about the internal set up as yet?


Richard

I was thinking of static any ideas of the size of bag I would need but need to wait till the gear box comes it was sent off to day from hongkong I order 20mm plastic plate to make blanking caps and internal blanks making them with double o rings

I am thinking of bending the rudder shafts at 2x9odeg angles and fitting a ball joint on each one and running two control rods or cable from one servo to each one as there is little space
some thing like this

Always fun and games trying to hook up rudders and dive planes in these small boats...you should try the Trumpeter Kilo!

The man I'd suggest you have a word with would be David Merriman, he's probably written a report on this by now...if not, there's some photos on here somewhere of the fittings kit for this boat, they should give you some ideas as to do it.
