just wanted to give an update on the acid bath stuff in ti. so actually corroding hss steel out of ti is not a fast process.
i found that putting some 12% hydrogen peroxide in the mix speeded the process up. the 30% hcl only seems to last a few hours.
also its good to keep everything horizontal, since the iron oxide that is produced can then flow in/out of the part. and new acid can get in.
hdpe plastic containers is good for this. i think it took about 3 days to melt out the tap. and about a week to melt out the drill bit. they both came out in pieces.
it might go faster if you mix in some water. but dont quote me on that. i just get the feeling that whatever you are trying to dissolve needs something to dissolve into.
well. just pouring acid in the threaded hole didn't do much to be honest. it wasn't until i filled the whole container up with 50/50 water/acid and then some hydrogen peroxide that i started to see actual results. it still only lasts for a few hours.
------------------
the rocca issue. muhle warrantied my rocca head. because of material flaws and the alignment issue.
but the new head they sent me also had the same alignment issue. no ****. i think i can tilt the blade about 5 degrees or so.
and while this might not be the end of the world. i think this should not happen on a cnc razor.
basically what they did is this: they machined the tabs to the blade dimensions when its laying flat.then its tight.
but in the razor, while in use the blade is curved very much.
and that also makes the aligning area much wider. maybe 0,15 to 0,2mm wider, since the blade is now bent in that area.
so now you a real possibility of misaligning the blade and that 0,15mm or so will result in about +-0,8-1mm left-right difference (up-down). and this will definitely affect your shaving. no ****. you increase the exposure by 0,5mm or so. lol
but yeah its not a big deal if you are used to DE razors you just adjust it by eye. but still i dont think its very good for a cnc:ed razor. and i have woked as a cnc operator/programmer. machining steel. several hundreds of kilos a day.
------
basically i was gonna send this razor to my cousin, but now i have to go there and instruct.
----------
the upside is that i got a slightly defective rocca head for free.
i immediately started to polish it with p1000 and p1500 paper and now its really nice.
-------------------
i also ordered a blackland gem razor. the sabre. i like some sabre rattling so i wanted a sabre.
we'll see how that one does.
i will post a review after a few uses. is it better than DE?? better than straights??
who knows. all i know is that im a bit poorer and that i will very soon own a sabre.
---------------------
oh yeah just wanted to get this info in.
about 3 days ago i fired up the feather as-d2 with 2 spacers under tha blade. and to my surprise it was so mild so i could go over the places where i missed several times. until it was all bbs. no ****. this must have been one of the closest shaves i have ever gotten. ever. and i was seriously contemplating just sending the **** to billhanna and be done with it. and let he sort it out
just to **** with him. but now i see an actual use for the mild razors. very eye opening.
sorry bill
with the razors that i think are good, you really cant "go back" and finish up. you would be totally ruined then. but with the feather you can. even with the 2 spacers. and you can go back until its done. just like a mach 3. well almost like a mach 3. almost.
anyway this is the handle i made for the incoming sabre. 30 grams. 13mm. ti. on the polished rocca head.
i'm not saying the rocca head is ****. but you need to do some manual adjustments imo. and if u can live with that its just as good (well almost as good) as the EJ 316 and the timeless OC .95mm ti. its a very heavy head. at 40 grams. EJ is 32g. and 0.95mm ti timeless OC is 22g. so yeah its heavy no matter what handle you put on there.
p1500 finish rocca head.
