[Cheap Chinese Laser Cutter]

I use an NJE n40630 laser module in my engraver /cutter . a really cheap module will not be very good or last long and power output is misleading .it really depends on what you refer to as cheap. I personally find the NJE modules consistent .

Fantastic work David you have inspired me to crack on with my Tigercat although nowhere near in the same league. 

[Have I learnt a lesson, or been lucky?]

If a series of prints are going well I never clean the plate if a minor problem creeps in then an application of pritt original on the weak area is all thats needed but every so often I remove the magnetic plate (prusa original) and give it a good wash with some detergent to degrease when the plate is refitted I run a first layer test and adjust if necessary then apply a thin layer of pritt stick . tall prints are best done on a 3 layer raft.

Usually when they start having extrusion problems there is burnt filament residue I only clean if in dire need otherwise always use new . One point is if you switch between different types of filaments that require a temp change change the nozzle i.e. pla to petg or flex etc may not cause a problem immediately but chances are it will in the middle of a print.

If you are interested there is a detailed article on the Aurora Model Manufacturing Co of Calcutta.

They formally took over production of all Mills engines, using the original tooling, as well manufacturing licenses for Allen Mercury diesels and the Taplin Twin. 

 

Thank you for that Simon very interesting reading and there is 1 mention of the K200 of which this certainly is. More mention of this engine anywhere is not available to me.The image supplied by John Lee looks to be it

Martian, the red and gold box top is the correct one for the engine you have. Maybe the previous owner was using the Mills box as lower/inner enclosure. 

Edit - Is the box picture with Mills .75 from other side of the same gold/red box ?

yes it is Manish 

[Please help identify]

Thanks guys . Jon that looks exactly like it funnily enough it even says Aurora manufacturing on the box 

[Please help identify]

Below some pics of a Diesel engine I recently bought , The box indicates it as a Mills .75 and another label as 2cc. it has a mark India on one side and the Mills logo on the other . I cannot find any reference to this engine featuring a front intake port and gold top.

coming along really well Colin , Re the guns only the barrel will be visible in the trough all the rest is in the cockpit unless you propose to drill through the cockpit which may not be easy now you have fitted the panel . My gun barrels are different to yours quite a few experiments were tried the first in use used the vickers machine gun with the water jacket still in place but the plugs remove then the barrels were lightened until your version with modified barrel jacket.

A cracking build Colin a credit to your tenacity , did you solve the strut retaining  ?

[Dom Smith F7F-3 Tigercat]

Well 1 nacelle is sort of done its been a real pain to get the main retract to sit right then carefully measured for gear doors it took numerous times to get them to sit right and hinge open so fitted gear back in only to find the the door over the wheel would not close so take doors off cut away part of the nacelle sides trim and refit doors its now as near as its going to get. No wonder there are so few builds for the cat having checked the only build log surviving on RCSB by Wingspar and reading the comments without exception they all have same problem. Lets hope nacelle 2 goes better . I've been struggling with this one for over a month obviously not non stop . Still plenty to do .I WILL NOT GIVE UP !

[Glue for PLA and PET-G]

Some info re pla glue I have used PVC pipe weld to good effect although not tried on wing panels yet , it successfully  dissolves a pla layer and gets stronger as it cures . Ok if you suffer from CA fumes and skin reactions.
