as some of you know i managed to re-own an old turret of mine , a martin 250 and i think according to the cast markings that it has come of a B26 Marauder.
Marauders , flying fortress along with many other aircraft were Burtonwoods main work load ,refitting ,assembly and some times complete rebuilds .As you can see ,it has now been completely stripped ready for the missing structural parts to welded into place.

a friend in the states has already sent some large electrical diagrams showing what gets connected to what and another friend said he might have a spare trigger unit.
I think the biggest things that i need to find are the perspex dome and the gunners seat, warbird parts have the ammo cans and a number of parts but what exactley i`m not sure.

Any how heres a couple of pictures...........

Very nice, Beats my desire for an E-13 .50 cal waist gun mount.

My dreams would be just to be able to borrow one to copy. Maybe one day.

A quick update , as you can see things are slow but coming together , one motor has been stripped and cleaned and the other one is half way through its rebuild.
the two canvas bags i found on ebay being sold as b17 top turret ammo bags , which i new there were not.
with this in mind i did some quick research and took a gamble that they were for the martin 250 turret and i was right! :D

i have been informed recentley that theres a low temperature alluminium welding process , have a look on u tube you will be impressed , i was that impressed i have just ordered some rods i will let you know how i go on?
the orange thing that you see is one of the old MG recoil units , seeing as this was the only decent unit i have made it into a pattern to have four new ones made.If it cant be used as is , it looks like i will have to make a split mould out of wood..........we`ll see? :?

Amazing what a clean and a bit of paint does!

Not sure which ali weld kit you've ordered, but I got some many years ago that worked well. I think it was called "Techno-weld" or something similar. Special ali welding rods and a stainless steel brush to clean the parts, plus a stainless rod to scratch through the oxide layer while the ali was hot to allow the welding rod to flow into the joint. It worked well, though took quite a bit of practice to get right. It was very easy on smaller parts to over heat them and melt everything.

Hi Colin

Looking good as usual!!

Somewhere I think I have stainless ammo feed chute for a 250 turret, will have to have a rummage through a few boxes and see what I come up with.

Will post a picture when I find it, could always trade for those Cletrac wheels I missed on eBay!!!

Cheers

Paul

Guess what the first box I went too in the roof had the stainless feed chute in it!!! Not a very big item I admit but I can see it being very costly to reproduce another one for the other side. At least you will have a pattern for it if you can not find another one.
This one came from an airfield dump site so at least has combat history!!
PM me your address and ill get it posted out this week for you.

Clearly for the 250 turret as you can see the three fixing holes on one of your cradles.

Also have a copy of the 250CE turret overhaul instructions and wiring diagrams you can borrow if that helps??

Cheers
Paul
