Valve spring compressor

My valve spring tool of 40 years (or more!) has gone into voluntary isolation and cannot be found (it was getting a bit worn anyway)
I have an air head BMW head to do and of course a few Vincent heads I have been looking on ebay at the Sealey type U type with a choice of adapters
(I say Sealey though there are lots of similar rip offs on the ebay search.)
Nub of my question is is that type any good for our old school heads? if not what reasonable priced one is?

Ebay item number 114143441056. Been using one like this for years, fits BMW airheads as it has the required depth of reach and also fits Vincent heads. However, be careful like so many tools it is liable to slip unless care is taken, not suggesting you would but l hope you can see where l am going, good luck.

Certainly looks suitable and vintage

I made me a few of these spring compressors at minimum costs. The tube dia. and cutout can be sized to the dia. of the spring cups. One cutout seems to be better than two, you don´t lose the valve collets so easily. I place the lot on my legs while sitting on a chair. So two hands will do the job with some training and I don´t need anything more since decades on all sorts of engines.

Maybe Robert will post a picture of his Smith's spring compressor. It is of a superior design.

Looking at the Smith´s type, what keeps the valve up - nothing ? And no universal compressor, just Vincent I guess.

Thanks for that! I went for that as its universal, having finished the Comet (awaiting some oil to start it up) my next job was going to be the Wife's EW Douglas new valves and guides but just as I went to load it on the bench I had an email to say Spares service from the Douglas club was suspended because of CV. So its got to be the 58 650 Triumph Trophy next (thats been waiting since before SORN started!) . So between that and the long project the Difazio I should get something out of this isolation policy- even if its only a shed full of bikes with nowhere to go

Happy to help, if for any reason it is not suitable let me know and l will lend you mine via the post. l well know the feeling about the frustration of being grounded despite living in the least densely populated part of the uk, but as its lambing time we have our hands full as it is!

The spring compressor received today package undergoing sunlight decontamination at the moment, thanks for the tip off thankfully I have all the parts to rebuild the BMW heads as I see all proper BMW parts supply outlets have closed and the non official outlets have some horrendous pattern parts (dont ask how I know).

Glad to be of help. Re BMW airhead valve parts l have found Swiss made intervalves and elco guides to be the most durable and long lasting, change at 50k intervals and avoid the heads breaking off! Agree there are some awful pattern parts as well, AE probably the worst with incorrect machining of the collet grooves. The elco guides are a tad longer which can only help in there longevity, PCV got it right with the two guide system, less potential for guide wear. Happy fettling!

Vibrac, I´d be interested to see that compressor, the Ebay number is not helpful to me? As to universal, the homemade device in my photos is cheap like anything and universal as you weld a tube to it as you like or suitable for any engine.

You have to smile, I lost a collet half on the job, and since I have swept the floor and heard it fall I went down on my hands and knees with a torch thinking "there aint no BMW shops open for some time!" finally I saw something glinting in a corner, and it was the collet half and next to it an unbroken set of ET36 collets and most amazing of all an ET38 (one of the lost 500) all in the space of half a matchbox!

Thanks for the photo - but that don´t impress me much. Looks a bit clumsy to me. My own device from an f-clamp got the quick range change as well and the tube cutting welded to the top got only one window cutout. Seems a bit awkward but isn´t - you don´t loose the split collets so easily , stay in the tube mostly when fiddling with installing them. A screwdriver grip on the threaded part of an f-clamp is quite allright, you only deal with max. 100 kg spring pressure so no factor. A deep reach f-clamp will do on practically all heads , not
speaking of hair pin springs of course.

I just use a bucket of oil on the shop floor to catch the stray collets. Hairspring compressor made from an old forge made set of forge tongs.
The other doodad allows you to launch two collets at a time into the oil bucket.
It is a required tool for doing 4 valve multi cylinder engines as it helps to prevent foaming at the mouth. That one exit hole is a good idea Vic.
Bit of porosity in that head. I think that’s where they got the idea for oilite bushings.

I have to sort the cables out but have been told it will do about 80 MPH, Covid-19 makes you do daft things :)
