Greetings Laplanders


XXXXXXXXXXXXXXX not work well see last post XXXXXXXXXXx

I bring U news of greater Joy than B4

Whot U say can it get better, well although nervana cannot B achived in this lifetime, I belive I am close

I have been toiling night n day 2 ensure Rose n Rosie r satisfied n content

They R lovely machines but have a flaw in that tend 2 grind more in centre so need 2 B costantly re flatted

If U go back 2 privoous post n refer 2 flat ruler / feeler guage first pic http://talk.craftweb.com/showthread...ghlight=Lapland pic

I am now keeping the 2 laps flat to within 0.05 mm if they not that flat they dont grind / polish properly

Flatting method on Rose grind is

Everflat tm

Flatting on Rosie polish with stuck down LP66 pad is

Fill n Go tm

This technology is developed from our ansesteral grind stone flatters ( I am shure they had a name ) but heavily modified

Get adhesive I use evo stick - time bond + thinners ( u need same one as glue )

1 part glue + 1 part wood flour fine + 1 part cerium + thinners

Use ruler ( this must B flat to within at least 0.05 mm ) stipple on adhesive mix -- scrape off with ruler carefully

Yes it is fesable 2 work 2 these tolerances

Then re stipple n tap with wire brush 2 get texture then re scrape off re do

Then using bit of hacksaw " saw " in the groovy pattern

Then when gone off properly gently scrape off any hight bits

Re check with feeler guage / ruler

During use take great care of water as may run a bit hotter also check 4 any none textured areas n re texture

I use ceriun + wash up liquid + bit of loose wood flour + water + drip, on polishing

Enjoy

Although my tips R 2 B used only by consenting adults in the privacey of there own homes

I should add a futher word of caution

Only try this on a pad u were going 2 throw away

Theses LP66 polyurethane pads have a weird property that if U put a lot of thinner on like toluine the pad softens n expands but it will come back normal if left untouched

So go easy on thinners n apply in thin layers rather than in a few millimeters, try it on an off cut

This particular adhesive has a good afinity n likeness 2 the LP66 n the 2 become 1 not all glues / adhesives R equal

My the flatness keep n remain with U always

Flatting hybred method is using diomond grinding blades which stick out from wt therby grind right 2 plate edge

Also this mwethod the "holder" can B repositioned depending on rings

http://talk.craftweb.com/showthread.php?s=&threadid=4955&highlight=lapland

These url thingies work n look same as B4

Weird, still it appears Rose n Rosie can still have fun even when they R not on

MayB Rosie is upset as she is currently covered in glue, I have assured her that all will B well, just a little patience persiverance n confidence

[Brian Blanthorn]

My earlier ephoria was some what missplaced

Although I used the Time Bond ( by itself ) on Lp66 some years in actual use and still holding on well

The wood cerium glue mix is comming off slightly

Technicaly the application was good n fairly easy n very flat overall

So next I will try same but more glue

I dont realy wanna research different glues

Sometime I feel like a reseach facility rather than manufacturing



May ur Lap stay ever flat

Brian, how far are you from Oxford? My daughter will be spending a year in school there as a transfer student from Smith and we wil likely come see her, and possibly you.

About 80 - 100 miles south strait road all the way about 2 hours or so n a nice journey but U gotta add on ferry about + 20 mins our side

But there is a bit of sea 2 cross but ferries run every 1/2 hour or so journey is usualy smooth n abour 1/2 to 1 hour

I would recomend U send a bit of time here we got thatched cottages n lovely scenery n stuff the whole place ( nearly ) is stuck in medieval / victorian time warp + other glass places if U feel the urge

Would B good 2 bond with fellow Laplander, Sally, Rose n Rosie would love 2 C U, and I belive U seen ur daughter already

As 2 the technology in this thread

The glue time bond has failed , partialy -- comming off yuck

But I am convinced with another 20 or so years of research I can get it sorted, anyway I have nothing else in my sad n empty life

I am convinced that the essence of the terchnology is sound and easaly doabble, just getting glue right

As pad wears in the centre n then I have 3 options

Failure -- get a proper jop ( but I dont do easaly failure )

Scrape off the entire rest of pade , yes I have done this

Fill pad , just the low centre part

The other glue a polyurethane wood adhisive worked well but the aplication was difficult

Any way I am now trying

Compensation Flatting tm

Crazed as it may seam I am "flatting " Rose ( 600 ) slightly convex by 0.05 or bit less at edge 2 compensate Rosies convex tendancy

I have just got a 6 mm LP66 as an unwanted surplus from my suppliers so that gives me 2 pads at about £50.00 total --- amasing

About time I had some luck


Pete how U holding ur glass on the laps ???????????????????

Mine R embedded in a big disk of wax

Brian

[Peter Bowles]

On the big lap its just clamped down gently in one corner, its a bit ugly but works well enough.

On the smaller laps the glass will gently rotate freely or it stays put by itself. Either way works as long as the piece moves about fairly evenly. I find that its much quicker to clean out and change the plates if they are not fixed down.

I've got a whole stack of old float that I am slowly working my way through that cost next to nothing to buy. I might feel less comfortable with this set up if I had to buy the glass. It does wear fairly quickly, especially with the 180 SiC but is so simple to do I reckon its a good way to go.

I dont have any holes in the glass so I have to change the grit quite frequently, but thats easy enough with a quick sponge down.

I've just set up a new tray with a piece of marine carpet and cerium and that is working well - not to a full polish but enough to make very easy work on a felt wheel.

I use a self emptying vac cleaner rather than lift plates
