Bronco Type XX111

Magnets...now that's an idea, Tom, I hadn't thought of that. Those little tiny ones, neo something...good thinking, sir.


Richard

There is an access hatch already marked out on the stern, I see...that would be ideal. Just right for a very careful cut with a fine razor saw blade.





Richard

There are some razors sow blades smaller than 1,5mm , as thiknes ?.
If someone knows that let as know PLEASE!.
I am interested too!!!.

Hands and fingers are feeling good today, so it's back to some proper building at last.

Having read all of David M's instructions, I'm about to join the two hull halves together today. They don't seem to be a particularly good fit, so it's going to be a case of glueing an inch at a time, I think.

Wish me luck...I'm going in.(well, after another coffee and a smoke...)

David M...am I right in thinking that I'll be ok to join the two hull halves initially with cyano from the outside, then once I've performed the 'long cut', I go over the join from the inside with plastic glue to weld the joint closed?

Richard

Consider putting in the torpedo doors before sealing. I would not use CA for the joining of the halves, but see what David says.

I was reading in the post about thin saw blades there is a set you can buy they come as a photo etch fret set

Good thinking, Tom...I'd forgotten about the doors.

I get my razor saw blades from eBay, Willie, all sizes available on there.

Bad idea: The CA will run significant lengths along the parts seam (the tighter the fit, the more aggressive the capillary travel). The solvent cement added later will be prevented from making contact with the polystyrene where the CA adhesive flowed and now acts as a mask.

Little of the model hull half contact points will be welded together. Most of the union will be secured with a shock-shatterable CA bond. Bad move!

Solvent weld all polystyrene to polystyrene parts, Richard. Cohesive (fusion) bonds are stronger than adhesive bonds.

David

That makes an awful lot of sense, David...I hadn't considered that. Thanks for the advice, much appreciated as usual.


Richard

Both hull sections glued up and drying off, looks as though it's been in a bad traffic accident and got rushed off to hospital for emergency surgery! I had to glue a couple of inches at a time, tape it together, glue another couple of inches...etc.

After very gingerly removing the masking tape...voila! I have a Type XX111 hull in one piece.

Bit of filling and sanding needed here and there, but it came out a whole lot better than I thought it would.

Next is the bit I'm dreading...the infamous ''long cut''. My ex wife could never understand why, after having bought a kit and spent ages glueing it together, I then spent ages cutting it half. That's women for you...

This is the above mentioned, and the most dreaded ''long cut''...one false move here, and the whole thing is ruined.

Had a bit of a bad pain today, so I didn't attempt the cut...maybe tomorrow, hopefully.


Richard

Are you doing the cut by hand or with a power tool?

It'll be done with my trusty razor saw...I managed to do the cut on a Revell Gato, so I'm hoping to replicate it again.

Richard, mine was a mess when I did my cut. You can always fix it.

A few strips of styrene strip and a spot of Andy's magic filler will cover anything, Tom...

Here we go then...hull all marked out, new razor saw bladed fitted...wish me luck, I'm  going in.

so come on then how did it go

Not good, couldn't get the cut lines level. I'll remark it out later after a beer.


(perhaps that's why I couldn't them straight last night?)

take your time mate you'll get there

What's that old saying...''slowly slowly, catchee monkey''?

Or in my case...''slowly slowly, markee straight lines''

Three times I've tried, and three times I've failed, to mark out the cut line accurately on the Type XX111, so I'm thinking of getting the right tool for the job.

David Merriman, what do you think to this? Any good?
