Burgess Sprayit Compressor

I have just bought for a small sum, an old Burgess Sprayit compressor.

It is the type with separate motor,with pump turned by a V belt. On checking it out, I find there is no oil in crankcase, but believe this is an oil-less compressor, so assume all is ok. I assume bearing are lubricated for life. If anyone has the instructions for one of these I could do with a scan please.

Google it, I googled for an instruction manual for portable hard drive & strimmer last year & came up with the instruction manual/ instructions, just type in the name & search.

I bought one about 40 years ago. Worked OK. Neither high pressure nor volume, but worked a spray gun (was likely a complete kit back then). I don’t know if I still have it or not. Runs dry and exhausts through the relief valve, at the top, when air is not used.

You bought it from Des 53? He had it in mid 2014.

I will look to see if I still have mine and hunt for the destruction manual as well.

The big question is this.

When I replace the cylinder head, do I turn crankshaft so that diaphragm is tightened when crankshaft is at TDC or is it tightened with diaphragm under tension at BDC,, or half way between. ?

Mike.

Simple logic says that the diaphragm should be 'flat' at mid-stroke, so that the stretch is equal at the dead centres.

Edit: it's a different pump, but this might help:

If it is your intention to spray paint with this you will need to use a 'continuous bleed' internal mix spraygun - there is neither the pressure nor the volume to use any other type (except an air brush of course)

As an example the high street store with initials MM only list one only of this type against many that demand more air, so I suspect most sprayguns you see advertised are unlikely to be be suitable. Check first.

With the right gun though, you can obtain a very good finish and I have in the (distant) past sprayed whole cars with one of these.

Some photos on this link while it lasts , may be of some use ?

Yes mine is the same as one in last photo. The photo I posted was one I grabbed on the net as have not had time to post my actual one.

Yes, mid stretch of diaphragm sounds right.. All is in remarkable condition except for paint flaking off both pump and motor, but that will soon be rectified.

I will not be using it for spray guns except my air brush and for tyre inflation.. I had the smaller version of one of these in the 60's and it was fine for spraying my Lambretta, and yes the gun, as supplied with the kit ,I believe had "max 30 or 50 psi"

on the pot. Very reliable and never let me down but graduated to a big beast with huge tank for bigger projects.

I had the SR122 version, definitely internal mix only, bought the proper external mix nozzle for the gun and it couldn't drive it. On a bigger compressor it was a good nozzle.

No machine, or operating destructions, here - well not that I can find. One cupboard, where it may be, is out of bounds currently (a large pile of scrap in front of it).
