Can you use engineers blue to find the best engagement ?This should be stuff I've cocked up today....
So I went to rebuild the reduction gearbox for my bandsaw conversion. Now it's been some months,since I stripped this - actually, thinking about it, it was allready stripped, in a box, with knackered bearings. So I'd bought two new tapered rollers for the output shaft, and one new biased ball bearing for the twin start worm. Straight away I wondered which shaft needed to go in first. I had a fiddle around, and it looked like there was enough room for the wheel to drop in. So I built up and fitted the worm, and tapped in the bilnd oilseal. Mistakes 1 and 2...
Then I pressed off and fitted the two tapered rollers, cleaning as I went. Now to drop in the output shaft - bugger... it wouldn't go in. So I had to spike the oilseal, pull it out and the worm, circlips, spacers etc.
So then I tried fitting the output shaft first, but it wouldn't, without removing the new end bearing. So I popped off the outer race to see if it would help (mistake 3). This is when 11 shiny balls flew all over the floor.
So that sort of shot the fox. Until I decided to do something I should have done in the first instance (mistake 4, or should it have been 1?). Fit the output shaft to check endfloat. Bloomin heck, it was slack, and the only shims I had were the gaskets. I'm not sure why, but the side cover bearing recess machining was really poor. So now I have to shim the bronze wheel. But which side? Do I go for half and half? Ie guess it? Anyway, new bearing and seal needed before I try again....
Well, I made some progress. Fitted the whole lot back together, removed som 3.5 thou plastic gasket shims, and it only just has zero play. If I take the last shim out it tightens up. The backlash between the shafts is still there, so I’m going with it as is.Can you use engineers blue to find the best engagement ?
Scary isn’t it. Mind you with all the ww2 activity at work I’ve been reading up about barnes Wallis. Fascinating bloke with some quite literally devastating ideas…If they were designed for WW2 type warfare I recon you need to go a trifle lower for todays ordinance ,say about 30 meters.
Thanks magnet I hadn’t, those are some really interesting shelters with some great history.Dont know if you've seen this . Quite good.

That’s interesting Anguz was there a German design or were there some that found there way over there?there are anderson shelters still in existence that the germans used, i have been in one
british through and through, still have the makers mark showing on them...Scary isn’t it. Mind you with all the ww2 activity at work I’ve been reading up about barnes Wallis. Fascinating bloke with some quite literally devastating ideas…

Planted some oats
Years ago we would sew wild ones!
Simple number plate for my house, anodised the plate black and the number just clear anodised.

@The_Yellow_Ardvark Show us your crum shot!
Sewing an oat, wild or otherwise would take some dexterity!
