[grendel]

so the teak was cut for the top rubbing strake across the transom (why did I say mahogany before) and its been fettled and fitted in place, glued and clamped.

I like the crash test dummy in the background, but the Griff lookalike does look appropriate.

I thoght the crash test dummy WAS the Griff lookalike

time to make some fairleads, this is 1/2" ling (12mm) from 3mm x3mm (1/8" square) brass rod, the slot drilled at 1.4mm, 1mm drill bit shown for comparison, photographed using a macro extender for the camera lens

[grendel]

a little bit of filing required I think

[grendel]

well thats taken a bit of time, what with shopping for myself, shopping for my parents and shopping for my mother in law (her clutch has gone and is being fixed next week) I have been kind of busy this weekend, however I still had some time to do some fine work, making more fairleads. now when I was doing the first I used my special drill bits for the job, but these are very brittle and easily broken, so it was back to resorting to hss drill bits, still in the 0.8mm and 1.3mm range (thats 1/32" and just under 1/16") at least these will drill brass and take some sideways stress. with some extra filing and cleaning up.we now have 4 fairleads.

[grendel]

next to polish them.

and then the stainless steel plates to be cut out and drilled, the important thing I have found is for the chuck to be perfect when holding the drill, if there is the slightest wobble, drilling stainless, the drill will break.

Also a gentle touch is required with the sort of drill size you are working with.

Oh dear! Poor woman. There's nothing worse than a slipping clutch for the ladies (so I've heard)!

This thread and of course the models was started before I became a forum member and somehow I didn't catch it!

Over the last 3 days I have read all 80 pages from beginning to end, like a book and I'm in total awe!!!!

Bravo Grendel, Bravo

this morning the first 4 fender plates were started, just  got to drill them and shape 8 more.

[grendel]

this is one on the real thing.

[grendel]

the parts already made are here

[JennyMorgan]

Very tiddly, Andrew through and through!

[grendel]

lots of work, 60 holes and 6 drill bits later

[grendel]

ok so looking at the next step for the fender plates the ring bolts to attach the fenders to, these have a small mounting plate 

[grendel]

some neatening up of the bottom plate is needed on that one (to square up the end mostly, then just 11 more to make.

[grendel]

plate neatened and 2 more plates done, 9 to go

[grendel]

Today i have finished the fender plates, and started fitting the plates to the boat, firstly the plates are polished up prior to the fitting.

[grendel]

stern fairleads and one of the fender mounts added

[grendel]

next one in place

[grendel]

so with one side done its turn the model round and start on the other side, also picking a servo for the steering and making a mount for it to sit against the bulkhead.

[grendel]

steering fitted to bulkhead, steering linkage added and tested

 

[grendel]

so while i may not have been posting regularly here, work has been ongoing, the stainless steel deck fittings have been completed, the mount for the battery has been positioned and fixed, and the electronic gear is being positioned ready for installation, just got to print the radio mount

[grendel]

Well two steps forward, one step back, all the wiring is in some still needs tidying up,  but when i was testing, i had no power to the motors, everything else worked fine, after some diagnostics i determined the speed controller was at fault, it was converting power for the receiver, but not supplying the motor. fortunately i had a spare to hand, so that was swapped in, and now everything is running, including the sound module.
