Hi Martin, thanks for posting, was a bit like a Pink Floyd lyric, "is there anybody out there"

I really enjoy applying tissue and I can do it very quickly these days.

As I cannot find a video on silk over tissue, I was thinking of doing a video of the process, applying tissue and then the silk. What do you reckon? worth the effort???

But the quick version:

The air-frame is given a coat of sanding sealer and a light sanding with 400

The tissue I cut over size by about an inch, laid over the airframe.

I use a fine mist atomiser and mist water onto the tissue, I get it fairly wet.

This allows me to gently pull all the wrinkles out and get some tension.

I then use full strength dope quickly applied around the edges, pulling a little tension if wrinkles appear.

I usually start with a long edge first like a leading edge. Withe a wing probably a couple of inch section in the leading edge then the trailing edge, working towards the tips. If you get wrinkles fresh dope will soften the bind and you can lift and tease the tissue taut.

The trick is speed. If the tissue does dry a quick mist of water helps, but it can also cause the tissue to sag. Ideally it should stay wet until you are all the way around. As it dries it shrinks and thats when the wrinkles appear if you haven't stuck the perimeter down.

Cheers

Danny

Applied one coat of 50/50 on the underside of the top wing centre section. This was than overlaid with my Ebay silk with about an inch overlap. I took a full jar of water and added probably a teaspoon of wallpaper paste (probably too much as the paste ended up quite thick)

350.jpg

Then brushed a line lengthwise down the panel. I then brushed from that centre-line, forwards then backwards, giving a generous coating. I could feel the tissue underneath was sagging a bit, so care needs to be taken.

Once done it doesn't look great. The silk seemed to kind of form tiny waves, or undulations. I had heard that it doesn't look good at first and you just have to be patient.....fingers crossed.....

Cheers

Danny

The trouble with this thread is that it's way, way beyong my pay grade I'm just awestruck by the beauty of this model construction. It doesn't help that I think the Hawker Nimrod is a great biplane (not as great as the Sopwith Pup, of course but ...)

So sorry for not commenting

Thanks for the terrif comments Chaps, but to prove once again Martian I am completely falable the silk is not right. And is really rough. Even after a couple of coats of dope

I should have started with a known constant and that is genuine Esaki silk. Learning a new technique with the wrong materials is fraught with perils. It doesn't matter too much in this instance as this section is under the wing, a bit out of sight and I am learning.

I have a much finer weave silk, probably still not the right stuff, which I have just tried to attach to the rudder, it is at least smoother, but I had to use dope to stick it down. And all the sages say Wallpaper paste is easier than dope. So again this isn't quite right. I am tempted to contact Mike Woodhouse of free flight supplies and see if he has some Esaki silk, I could at least perfect the technique, even if it is just on the rudder

Anyway if it were easy everybody would do it!

Cheers

Danny

Sometimes I really do worry about my sanity. Several months ago I spent a small fortune on silks trying to match Esaki. I have covered the centre section in the same rubbish I did the cabane struts in.... Doh!! I have just rummaged through my silks and have covered the rudder in another silk that looks right but i think is polyester as it fluffs like crazy. Still not right.

I just waded back through the thread and we have been through all this and I ended up contacting Bill Dennis, who pointed me at Haringtons, as Alan had done..... I really don't know how I remember to get up some days.

Anyway am about to tissue the tailplane, and we will try the Harringtons silk with wallpaper paste on that.... stand by.

I may even video the process for Martin

Cheers

I bought Esaki Silk from Mike Woodhouse (Freeflight Supplies). Only heavyweight is available now Danny. I bought it for my FF Scale Bucker but am worried that it may be too heavy.

Rather expensive as well..

Just looked on the Harrington Website. Do you know what material you should be looking for?

The only silk I could find was described as medium heavy and is very expensive..

I contacted Mike last night and he said he had some Esaki lightweight left, but not much. A bit of green apparently. £18 a pack, which I think is roughly a sq/mtr.

The Silk that Bill pointed me too is made by Harrington, I had to ring them and ask for the specific type as it is not on the website.

4202i is the catalogue number you need Martyn. Not a lot cheaper than Mike, so it is up to you.

I am in the middle of making a video showing the stuff in action. Hopefully be online later today.

Cheers

Okay the tissue video is in the can, will be online shortly. really only to be viewed if you cannot sleep, its an hour long and took three times that to film and edit...... Still it is keeping the old skills, or at least my take on them alive.

There was so much more I could have said, but never mind......

I have spent the day doing lots of tissue work, almost getting the hang of it now

While I was busy working, these two reprobates sank up to their elbows in my building board.....

Many thanks to Dave Banks, once again creating some real works of art
