mortar almost finished
« Reply #30 on: January 17, 2009, 02:34:11 AM »
Here are some pics of the mortar almost finished.
I still have to do some sanding on the carriage as there are some sawmarks left but i bolted it all together to see the result.
I know i did'nt use "traditional" materials but overall i am pleased with the result and i like to use whatever is availiable for free.
After sanding i plan to sandblast the carriage so you don't see too much it is ertalon as original the plates are like shiny plastic.Actually it is nylon.
Sandblasting gives it an overall gray matte finish.
Next thing is shooting it tomorrow,can't wait too see the results... ;D

WOW!!!!!!!!!!
That is a very great looking mortar. I really like the elevating mechanism. The only problem I see with having the
base made out of nylon is that any fragments of burned fuse will probably leave squiggly black burns in the material.
On my wooden base I screwed down an aluminum plate painted black so the wood wouldn't be marred.
I can't think of anyone who wouldn't be prouder than the dickens to have that great looking mortar in their arsenal.
Congrats!!!!!!!

Excellent!

Love that stainless/black scheme, an all-weather tactical GB mortar!


I see you've already addressed the trunnion straps. The reason that I asked about the trunnion diameter is that I still have the trimmings from the ones I made (also stainless steel). The stock was wider than needed, and trimmed after forming.

At 1.150" (29.2 mm) diameter, they probably would've been close enough to fit, but they would've been a little narrow.


It was the getting them to Belgium part that I hadn't worked out...  ???

Thank you very much for the compliments and for thinking about the straps Terry.Also thank you for your posts about the GB mortar as it was very usefull too me!
I don't think i will bother about the sparks as i don't mind when it gets some use marks,after all it is made for shooting and using it...right? 
If it does'nt burn in too much offcourse because then i will add a plate... :-\
As for the straps i will turn out a 1,5 mm deep groove where they sit as the trunnion is 30 mm and the straps are a bit too small.
Also this groove will eliminate any right/left shift and then i can screw them tight on the carriage as now there is a small gap and if i tighten them the barrel
sits too tight.
Anyway,this was a nice project.
I have some airgun to tune now for my son and then i can focus on the dahlgren. ;D
