Hi, slowly eating the elephant :big: and that's just the to do list but onto the engine. The conrods have been fabricated agreed not the best way and they took longer to straighten out than make but got there in the end.
The big end eye was bored out I must get with this metric age and buy some reamers

Then the rods were simply hand filled to shape it seems to be a lost art now but I find it often quicker to use hand toools as the set up time for a machine can be greater and there was only two to make

Then a simple jig was made so that they could be hard soldered

Then the cams these for some reason had been giving me a hard time just getting the sequence into my rather muddled head :big:
The blanks were turned to dia and clocked in on the mill and the offset and the crank positions drilled then back to the lathe and set up in the four jaw to machine the rear profile I know it should be all done on the mill but just couldn't get my thick head around how

Then the big end pins and retaining bolts were made just simple turning jobs as were the pistons

Thats about it for now as time is short at the moment the progress is slow

Thanks for the kind remarks and encouragement
best wishes to all
Frazer

Sorry for the delay in updating the build but play time is a very scarce commodity at the moment.
Thanks for the kind comments
Next up the burners they are made from some copper end feed fittings in the same way as Little Blazer

They were set up in the mill on a simple jig to drill the hole for the burner tube

The bases were cut from sheet brass using a piercing saw I just love using this saw it saves so much time and a quick clean up with a file is all is needed they are a joy to use although maybe I'm biased as iv used one for oh to many years :big:

They were then hard soldered up and cleaned

The holders are along the lines again of Blazer just a simple little bit of piano wire

Next up the valve assemblies

I made a small jig to mill the slots for the valve buckel but make sure you get the right oriantation :

Then a little play time as Little Blazer was just crying for a run :big:

Be back soon :big:
best wishes frazer

The fuel tanks/lamps look great, Frazer. The Little Blazer run at the end was fun, too.

 

[fcheslop]

Thanks for looking in Dean :big:
Next up the timing was set and the big moment it would pop and spit and run for about ten seconds followed by a couple of hour of finger burning fun so after 6 doubles no not that sort these :big:

espresso porn :big: :big:
The springs were distorting as the engine heated up.so they were normalised in a fashion with a blow lamp then another try :big: :big: as per Mr Ridders instruction on one cylinder

Then on two

Still not perfect as the springs still need a little tweaking but its of to the bling fairies for this one then the set up procedure repeated.OOPs wrong way round
kind regards Frazer

Hi,after a quick trip to the bling fairies I think this project is now finished many thanks to all for the offers of materials and the kind comments
I would like to close this build by thanking Jan for sending me the drawing they are excellent and I have had no problems building from them

kind regards Frazer

:bow: Well done Frazer - congratulations!

;D I see you also like coffee and a quick run of the blazer once in a while...

Kind regards, Arnold

 

[Deanofid]

As usual, a great job, Frazer. Runs like a top, and looks great too.

 

[fcheslop]

Thanks again gents.
Thanks Dean
Hi Arnold Little Blazer has to be my favourite out of all the ones I have built as to the coffee I need my fix strong and Italian :big:
